WHAT IS THE CARAMEL COLOR MADE FROM?
Caramel Color is a water soluble viscous electro positive liquid color.
Caramel color is made by heat treatment of carbohydrates.
Caramel color's color can range from pale yellow to amber to dark brown.
Caramel color is one of the oldest and most widely used food colorings.
Caramel Color is classfied as an ammonia caramel, baker’s caramel, confectioner’s caramel and beer caramel.
Caramel Color can be used in beer, sauces and confectionary food and beverages based applications.
Caramel colours are produced from various carbohydrates like wheat, corn -dextrose, invert sugar, malt syrup from barley, molasses, lactose, wheat and corn starch hydrolysates, which are heated in the presence of acids like sulfites, alkalies like ammonium and the salts like ammonium, bicarbonate, sulfate and bisulfite.
There are two categories of raw materials for the manufacturing of this color, carbohydrates and reactants.
1. Sources of carbohydrates:
Food grade nutritive sweeteners which are the monomers glucose and fructose and/or polymers thereof, e.g. glucose syrups, sucrose, and/or invert syrups, and dextrose are the sources of carbohydrates.
2. Reactants:
The approved reactants such as acids, alkalis, salts, ammonium and sulfite, which are used to promote caramelization.
HOW TO MAKE CARAMEL COLOR?
Four types of this color are all produced from carefully controlled heat treatment of food grade carbohydrates with food grade reactants or not.
The process also called caramelization.
4 Types of Caramel Color:
The joint FAO/WHO Expert Committee on Food Additives (JECFA) has divided it into four classes based on different reactants (catalysts) in the manufacturing process, simply named class I, II, III & IV and with the corresponding E number E150a, 150b, 150c and 150d.
CARAMEL PROPERTIES:
The caramel process reaction end-point is determined from a combination of specific gravity, pH and viscosity.
Caramel color is a complex mixture of charged compounds, some of which are in the form of colloidal aggregates.
Caramel usually is a dark brown to black liquid or solid having an odor of burnt sugar and a somewhat bitter taste.
Caramel colors have isoelectric points and pH levels varying over a wide range.
The colloidal charge of caramel is strongly influenced by pH, so by changing the pH of caramel solutions, the isoelectric point where the charge is neutralized can be reached.
Further pH adjustments will cause the charge to switch to the opposite polarity.
In coloring a product with caramel, the particles of the caramel color must have the same charge as the colloidal particles of the product to be colored.
If a caramel color is put into a colloidal solution with oppositely charged particles, the particles will attract one another, form larger insoluble particles, and settle out.
For example, a soft drink contains negatively charged colloidal particles; therefore, a negative caramel color should always be used.
Conversely, beer contains positively charged proteins.
Therefore, the addition of negative-charged caramel creates a cloud that agglomerates into particles large enough to precipitate quickly.
For this reason, positively charged, beer-stable caramel should be selected.
In personal care, positively charged caramel would be utilized in conjunction with positively charged ingredients such as cationics or proteins.
Negatively charged caramels work well in whiskeys, wines, rums and liquors.
Wines clarified using gelatin and tannic acid require enough tannic acid to remove the entire gelatin, otherwise the remaining positively charged gelatin and negatively charged caramel will precipitate and be removed during the filtration process, making the wine perceptibly lighter in color.
Similarly, negatively charged caramels would be utilized in personal care in conjunction with negatively charged formulations such as anionic surfactant systems.
WHY ARE THERE FOUR CLASSES?
It is created through the controlled heating of sugars from sources such as corn, wheat, and sugar beet and they can range in hue from golden to dark brown.
Based on the type of reactant that is used, the caramel is divided into one of four different types, or classes.
They are: Class I (E150a), Class II (E150b), Class III (E150c), and Class IV (E150d).
Each class of caramel color has different specifications on color intensity and hue.
And while they are all favored for certain application, caramel color generally has excellent heat, light, and acid stability and works in many different applications.
Caramel Colour is Yellowish Brown to Blackish Brown Colour produced by heating food grade carbohydrates like Corn Syrup or Sugar in a controlled environment in the presence of alkalis.
The colour is naturally stable in application conditions like acidity, direct Sunlight and high process temperatures.
Caramel color is made by heating carbohydrates (i.e. sugar), which is the caramelization process.
Commercially, many different sweeteners are used to make caramel color:
*Fructose
*Glucose
*White Sugar (sucrose)
*Malt syrup
*Molasses
*Starch hydrolysates
Caramel color is one of the oldest and most widely used food colorings, and is found in many commercially produced foods and beverages.
Caramel is a form of carbohydrate that is formed by the process known as caramelization.
Caramel is extensively used as a coloring agent in the food additives.
Caramel is available in four different forms namely plain caramel, caustic sulfite caramel, ammonia caramel and ammonia-sulfite caramel.
Caramel provides a broad spectrum of stable colors to the food ranging from light yellow to dark brown depending upon the type of caramel used.
Caramel Color is a dark brown liquid material derived from controlled heat treatment of fine grade crystal sugar with or without some additive reagent.
Caramel color is defined and regulated as a food color additive.
Internationally the FAO/WHO Joint Expert Committee on Food Additives (JECFA) has divided Caramel Color into four classes depending on the food grade reactants used in its manufacturing:
E150 a - Class I is Plain Caramel Color
E150 b - Class II is Caustic Sulfite Process Caramel Color
E150 c - Class III is Ammonia Process Caramel Color
E150 d - Class IV is Sulfite Ammonia Process Caramel Color
Caramel color or caramel coloring is a water-soluble food coloring.
Caramel color is made by heat treatment of carbohydrates (sugars), in general in the presence of acids, alkalis, or salts, in a process called caramelization.
Caramel color is more fully oxidized than caramel candy, and has an odor of burnt sugar and a somewhat bitter taste.
Caramel color's color ranges from pale yellow to amber to dark brown.
Caramel color is one of the oldest and most widely used food colorings for enhancing naturally occurring colors, correcting natural variations in color, and replacing color that is lost to light degradation during food processing and storage.
The use of caramel color as a food additive in the brewing industry in the 19th century is the first recorded instance of it being manufactured and used on a wide scale.
Caramel color is a colloid.
Though the primary function of caramel color is for coloration, it also serves additional functions.
In soft drinks, Caramel color can function as an emulsifier to help inhibit the formation of certain types of "floc" and its light protective quality can aid in preventing oxidation of the flavoring components in bottled beverages.
Caramel color has excellent microbiological stability.
Since it is manufactured under very high temperature, high acidity, high pressure, and high.
Each class consists of a variety of caramels with their own unique properties that make it suitable for use in specific foods and/or beverages.
Color intensity (or, tinctorial power) is defined as the absorbance of a 1 mg/mL (0.1% weight/volume) solution in water, measured using a 1 cm light path at a wavelength of 610 nanometers (or 560 nm for tinctorial power).
In this case, A stands for absorbance and TS stands for total solids.
The color tone of the caramel color is also important.
This is defined by the Linner Hue Index, which is the measure of the color hue or red characteristics of the caramel color.
Caramel color is a function of the absorbance of light of wavelengths 510 and 610 nm.
In general, the higher the Tinctorial Power, K0.56, the lower the Hue Index and the lower the red tones.

Karamel renkleri, buğday, mısır-dekstroz, invert şeker, arpa malt şurubu, melas, laktoz, buğday ve mısır nişastası hidrolizatları gibi çeşitli karbonhidratların sülfit gibi asitler, amonyum gibi alkaliler ve benzeri tuzların varlığında ısıtılarak üretilir.
Bu rengin üretimi için iki hammadde kategorisi vardır; karbonhidratlar ve reaktanlar.
1. Karbonhidrat kaynakları:
Glikoz ve fruktoz monomerleri olan gıda sınıfı besleyici tatlandırıcılar ve/veya bunların polimerleri, örneğin glikoz şurupları, sakaroz ve/veya invert şuruplar ve dekstroz, karbonhidrat kaynaklarıdır.
2. Reaktanlar:
Karamelizasyonu desteklemek için kullanılan asitler, alkaliler, tuzlar, amonyum ve sülfit gibi onaylı reaktanlardır.
KARAMEL RENK NASIL YAPILIR?
Bu rengin dört çeşidi, gıda sınıfı karbonhidratların gıda sınıfı reaktanlarla dikkatlice kontrol edilen ısıl işleminden üretilir.
İşlem ayrıca karamelizasyon olarak da adlandırılır.
4 Çeşit Karamel Rengi:
Ortak FAO/WHO Gıda Katkı Maddeleri Uzman Komitesi (JECFA), üretim sürecindeki farklı reaktanlara (katalizörler) dayalı olarak, basitçe sınıf I, II, III ve IV olarak adlandırılan ve karşılık gelen E numarası E150a, 150b, 150c ve 150d ile dört sınıfa ayırmıştır.
KARAMEL ÖZELLİKLERİ:
Karamel proses reaksiyonu son noktası, özgül ağırlık, pH ve viskozitenin bir kombinasyonundan belirlenir.
Karamel rengi, bazıları kolloidal agregalar biçiminde olan yüklü bileşiklerin karmaşık bir karışımıdır.
Karamel genellikle koyu kahverengi ila siyah bir sıvı veya yanık şeker kokusuna ve biraz acı bir tada sahip katıdır.
Karamel renkleri, geniş bir aralıkta değişen izoelektrik noktalara ve pH seviyelerine sahiptir.
Karamelin kolloidal yükü pH'dan güçlü bir şekilde etkilenir, bu nedenle karamel çözeltilerinin pH'ı değiştirilerek yükün nötralize edildiği izoelektrik noktaya ulaşılabilir.
Daha fazla pH ayarlaması, şarjın ters polariteye geçmesine neden olacaktır.
Bir ürünü karamel ile renklendirirken, karamel renginin tanecikleri, renklendirilecek ürünün kolloidal tanecikleri ile aynı yüke sahip olmalıdır.
Zıt yüklü parçacıklar içeren koloidal bir çözeltiye karamel rengi konursa, parçacıklar birbirini çeker, daha büyük çözünmeyen parçacıklar oluşturur ve çöker.
Örneğin, bir meşrubat, negatif yüklü koloidal parçacıklar içerir; bu nedenle her zaman negatif karamel rengi kullanılmalıdır.
Tersine, bira pozitif yüklü proteinler içerir.
Bu nedenle, negatif yüklü karamelin eklenmesi, hızla çökelecek kadar büyük parçacıklar halinde topaklaşan bir bulut oluşturur.
Bu nedenle pozitif yüklü, biraya dayanıklı karamel seçilmelidir.
Kişisel bakımda, pozitif yüklü karamel, katyonikler veya proteinler gibi pozitif yüklü bileşenlerle birlikte kullanılacaktır.
Negatif yüklü karameller viski, şarap, rom ve likörlerde iyi sonuç verir.
Jelatin ve tanik asit kullanılarak berraklaştırılan şaraplar, tüm jelatini çıkarmak için yeterli tanik asit gerektirir, aksi takdirde kalan pozitif yüklü jelatin ve negatif yüklü karamel, süzme işlemi sırasında çökelecek ve şarabın rengini belirgin şekilde daha açık hale getirecektir.
Benzer şekilde, negatif yüklü karameller, kişisel bakımda, anyonik yüzey aktif madde sistemleri gibi negatif yüklü formülasyonlarla birlikte kullanılacaktır.
NEDEN DÖRT SINIF VAR?
Mısır, buğday ve şeker pancarı gibi kaynaklardan gelen şekerlerin kontrollü ısıtılmasıyla oluşturulur ve altın renginden koyu kahverengiye kadar değişen tonlarda olabilirler.
Kullanılan reaktan tipine bağlı olarak karamel, dört farklı tipten veya sınıftan birine ayrılır.
Bunlar: Sınıf I (E150a), Sınıf II (E150b), Sınıf III (E150c) ve Sınıf IV (E150d).

Caramel color is widely approved for use in food globally.
PRODUCTION:
Caramel color is manufactured by heating carbohydrates, either alone or in the presence of acids, alkalis, and/or salts. Caramel color is produced from commercially available nutritive sweeteners consisting of fructose, dextrose (glucose), invert sugar, sucrose, malt syrup, molasses, starch hydrolysates, and fractions thereof.
The acids that may be used are sulfuric, sulfurous, phosphoric, acetic, and citric acids; the alkalis are ammonium, sodium, potassium, and calcium hydroxides; and the salts are ammonium, sodium, and potassium carbonate, bicarbonate, phosphate (including mono- and dibasic), sulfate, and bisulfite.
Antifoaming agents, such as polyglycerol esters of fatty acids, may be used as processing aids during manufacture.
Caramel color's color ranges from pale yellow to amber to dark brown.
Caramel color molecules carry either a positive or a negative charge depending upon the reactants used in their manufacture. Problems such as precipitation, flocculation, or migration can be eliminated with the use of a properly charged caramel color for the intended application.
Caramel color has excellent microbiological stability.
Since Caramel color is manufactured under very high temperature, high acidity, high pressure, and high specific gravity, Caramel color is essentially sterile, as Caramel color will not support microbial growth unless in a dilute solution.
When reacted with sulfites, caramel color may retain traces of sulfite after processing.
However, in finished food products, labeling is usually required only for sulfite levels above 10 ppm.
Caramel colour is a water soluble food colouring made by heating carbohydrates, often in the presence of acids, alkalis or salts.
Caramel color is one of the oldest and most widely used food colourings and can be found in many food products.
The greatest use of the colour is in beverages such as colas.
There are four classes of caramel colour, depending on how it is manufactured.
Class III and Class IV can use ammonia in the preparation; whereas Class I
and II cannot.
In the United States, the Food Chemicals Codex defines caramel color and lists the carbohydrates, acids, bases and salts allowed in its manufacture.
It also lists the four classes of caramel color:
Class I (Plain Caramel):
Prepared by heating carbohydrates with or without acids or alkalies; no ammonium or sulfite compounds are used.
Class II (Caustic Sulfite Caramel):
Prepared by heating carbohydrates with or without acids or alkalies in the presence of sulfite compounds; no ammonium compounds are used.
Class III (Ammonia Caramel):
Prepared by heating carbohydrates with or without acids or alkalies in the presence of ammonium compounds; no sulfite compounds are used.
Class IV (Sulfite Ammonia Caramel):
Prepared by heating carbohydrates with or without acids or alkalies in the presence of both sulfite and ammonium compounds.
Each class of caramel color has specific characteristics based on the reactants used: Class I caramel colors have a neutral ionic charge; Class II are very negative; Class III are strongly positive; and Class IV are strongly negative.
The ionic charge is important in matching a color to a product.
If a positive caramel is mixed in a solution with a product containing negative ions, they will attract each other and produce a haze, or even precipitate.
For example, coffee's negative ions, plus a Class III caramel, has this effect, so Class IV or Class I is best.
WHAT IS CARAMEL COLOR MADE OF?
As caramelization is a complex and poorly understood process that produces hundreds of chemical products, so caramel color is a mixture and there are no specific compositions in it.
The caramelization reaction is the browning of sugar during the cooking process.
During the process, carbohydrates are incompletely decomposed, dehydrated and polymerized at high temperatures, and the degree is closely related to temperature and the type of carbohydrate.
For example, sucrose forms glucose and fructan at 160°C.
Isotopecane (C12H24O10)n is formed at 185 to 190°C, and it is polymerized to caramel alkane (C24H36O18)n and caramel olefins (C36H50O25)n at about 200°C, and caramel alkyne (C24H36O13)n will be generated at 200°C or more.
Tinctorial power, K0.560: Caramel color is defined as the absorbance of a 0.1% weight/volume solution measured through a 1 cm light path at a wavelength of 560 nanometers using a high quality spectrophotometer.
The higher the Tinctorial Power, K0.560, the darker the Caramel Color.
Color intensity: Caramel color is defined as the absorbance of a 0.1% (w/v) solution of caramel color solids in water in a 1-cm cell at 610 nm.
Hue index:
Hue index is one way to measure the redness of caramel color.
Caramel color is a function of the absorbance measured at wavelengths of 510 and 610 nanometers.
The higher this index, the more red of caramel color.
Class I: hues range from yellow to red-brown
Class II: hues range from very yellow to dark red-brown
Class III: hues range from a light brown to dark red-brown.
Class IV: a light brown to deep black-brown.
Ionic charge
Caramel color carries ionic (electrochemical) colloidal charges, positive, negative or neutral depending on the manufacturing processing.
Most of the caramel color consumed today is negatively charged. Generally, the application is related to the ionic charges.
Class I (E150a), has a slight negative colloidal charge.
It does not contain 4-MeI or sulfites, generally used in bread, spirits, dairy, beverages and confections.
Class II (E150b), has a negative colloidal charge and without 4-MeI.
Commonly used in tea, whiskey, and brandy.
Class III (E150c) has a positive colloidal charge and used to color soy sauce and beer.
Class IV (E150d), has a strong negative charge over a wide pH range, and widely used in the soft drink industry.
The specific application is complicated, usually, there are several classes can be used in a field.
Caramel color's safety when used as a food additive has been approved by the U.S. Food and Drug Administration (FDA), European Food Safety Authority (EFSA), Joint FAO/WHO Expert Committee on Food Additives (JECFA), as well as other authorities.
Caramel color is generally recognized as safe (GRAS) when used in accordance with good manufacturing practice.
Caramel colours are colouring substances authorised as food additives in European Union (EU) in accordance with Annex II and Annex III to Regulation (EC) No 1333/2008 on food additives and categorized as “Colours”
Ever wondered why caramel color (E150) is everywhere?
That’s because caramel color is one of the most widely used food coloring in the world.
It dates back to the 19th century when caramel color was first used commercially for the brewing industry.
Then in the 20th century, soft drink companies started using caramel color not only as a colorant, but as an emulsifying agent as well.
Today, caramel color comes in solid or liquid form, water-soluble and gives foods color that ranges from light yellow to dark brown.
Caramel color has a wide range of applications.
Although there are some considerations that food manufacturers take a look into when using caramel color.
Two of them are color stability and compatibility with the food process and/or the ingredients.
There are other other food additives that can make food products visually appealing to customers.
COLOR INTENSITY:
The color intensity of caramel is defined as the absorbance of a 0.1% w/w solution of caramel color solids in water in a 1-cm cell at 610 nm.
Percent solids are used in the calculation.
The color intensity of caramel is dynamic and will lighten over time during shelf storage.
This, and the percent of caramel added, affects the color of the final formulation.
A little caramel goes a long way to develop an intense caramel to dark brown colored formula.
However, process variations in the production of caramel can cause deviations in the final resultant color.
Therefore, it is critical to develop tight specifications on the color of caramel to minimize color variation in the final formulation.
FORMULATING WITH CARAMEL:
As noted, the isoelectric point is the pH at which the colloidal charge is neutral, and this is established by both the ingredients and the caramel coloring process.
A negatively charged caramel color has a pH higher than its isoelectric point.
The methods used to determine this neutral point are based on the mutual attraction of particles with opposite charges.
The procedure generally employs solutions with a known colloidal charge to detect the pH at which the charge of the caramel color particles changes.
It is suggested that the isoelectric point of a formula be determined before using caramel liquids.
For example, caramels in Class III have a charge that is usually positive up to around pH 5, then the isoelectric point will be between pH 5 and 7 depending on the product; above this pH, it will be negative.
In contrast, Class IV caramels have a negative charge above pH 2 and the isoelectric point will usually be between pH 0.5 and 2; below this pH, it will be positive.
As previously mentioned, caramel’s role in personal care is as a colorant and several products recently launched to the marketplace that contain caramel exemplify revived interest in this natural ingredient.
WIHT MANY SELECTIONS OF FOOD COLORING, WHY CARAMEL?
You can’t blame food manufacturers why they mostly, if not entirely, rely on caramel color.
The product of caramelization is relatively economical, readily available and easy to use.
Plus, its bland aroma and mild flavor do not significantly affect the flavor profile of the finished product.
The process of making caramel color
Like the name suggests, caramel color is made through a process called caramelization.
Caramelization is a process that involves controlled heat treatment of carbohydrates.
When making caramel color, reactants may be added. Basically, carbohydrates are food grade nutritive sweeteners that are commercially available.
These may consist of glucose, fructose, sucrose, invert sugar, molasses, maltose, and starch hydrolysates.
Among these, fructose creates the darkest color as it caramelizes the fastest at 230°F (110°C).
While maltose requires at least 356°F (180°C) to caramelize.
Caramel color can be manufactured without a reactant (Class I).
But food grade reactants such as an acid, alkali or salt may be added to assist in the caramelization and make a variety of caramel colors.
There are 4 classes of caramel color.
Each of them has its own distinct properties to satisfy the requirements of a specific application or food process.
Checking and standardization using a measuring equipment helps determine the color changes during processing, and storage, and control the color of the final product.
The color intensity or value refers to the absorbance of a 1 mg/mL (0.1% weight/volume) solution in water.
This refers to the brightness and visibility of a food product, to put it simply.
Commonly, the intensity of color is measured using a ratio of absorbance values.
In chemistry, absorbance value refers to the quantity of light absorbed by a sample (caramel color).
This is determined through spectral analysis using an equipment like a spectrophotometer.
Through the Hue Index, the results are analyzed.
Basically, the Hue Index determines objectively how red (or yellow) the caramel color is.
The higher the value of the Hue Index, the more red or yellow the caramel color is.
The range of the Hue Index for caramel color is around 3.5 to 7.5 at 0.1 solution.
Generally, the higher the color intensity, the lower the hue index.
Caramel food colouring is made by heating or burning sugar (or various other carbohydrates) and mixing it with an acid or alkali (ammonium, sulfites).
Just like Annatto, Caramel is also a ‘natural’ additive because it is derived from natural sources such as sugar cane and carbohydrates.
Caramel Colours provide a range from light yellow to reddish brown to dark brown.
Each and every type of caramel colour has its own unique colour tone and properties produced for special application.
Caramel Colour is one of the most versatile and stable colours available in liquid form, widely used in almost every category of commercially produced food.
CARAMEL COLOR QUALITIES:
The basic laboratory data for caramel colors consists of four characteristics: color, Baume, hue, and pH.
Color strength is measured as tinctorial power (absorbance at 560 nm of a 0.1% solution in a 1 cm cell), or color intensity (the same solution at 610 nm).
The pH is measured on an as-is basis.
A good pH measurement requires five or more minutes for the pH probe to equilibrate due to the high solids content of caramel colors.
Baume, or specific gravity, is a measure of the solids content, and is usually done with a density spindle or the newer electronic densitometers.
The final parameter is hue (Hue Index), which is a measurement of the degree of redness.
Typically, the Class I caramel colors are the reddest and have a higher index, followed by Class III.
Class IV caramel colors have the lowest hue, and are the least red.
There are many more tests, like salt and alcohol solubility, but these are more dependent on the designed use of the product.
All caramel colors are water soluble. However, they can be dispersed in oil, but this often requires emulsifiers, such as lecithin, resulting in pastes or emulsions.
Caramel colors change with age.
When they are manufactured, the carbohydrate and chemicals are heated to a high temperature (often under pressure) to form large polymers that generate the color.
When the desired color end point is reached, the reaction mass is cooled to stop the reactions.
In reality, the reactions never stop, they simply slow down.
So, as the product ages, the pH decreases while the color strength and viscosity increase.
The biggest change is often viscosity. However, a modern caramel color is shelf stable for two years or more, but as it ages it thickens.
Using fresh samples will ensure a sample represents the product sold.
The four types of caramel coloring include plain caramel; a type that reacts sugar with sulfites; one that reacts sugars with ammonium compounds; and one that reacts sugars with both ammonium and sulfite compounds — the type of coloring used in most sodas.
Caramel coloring is also found in brown bread, chocolate, cough drops, vinegars, custards, fillings, doughnuts, gravy browning and many other food products.
Caramel coloring is one of the oldest and most widely-used food colorings, the same substance that makes your colas brown and gives beers their amber gold.
Though it sounds natural, caramel coloring is not the same as the candy confection.
Caramel LFC is a dark brown liquid obtained by the controlled heat treatment of glucose, in presence of ammonium hydroxide.
The presence of amine functions enables its stability in acidic medium and gives it a positive colloidal charge.
Caramel color is a water-soluble food colorant which is made by heat treatment of carbohydrates.
Caramel color is widely used in beverage, soy sauce, etc., bringing attractive and appealing color to foods.
Caramel color is also called the Color of Soy Sauce in China, because it was first found in the fermentation of soy sauce.
After years of research, caramel color has been proved to be safe and effective in a variety of food applications with few limits of dosage.
Nowadays, caramel color has become the world’s most widely used food colorant.
Caramel color production always starts with a carbohydrate source and high heat.
Subsequent modifications, however, alter their chemistry, physical properties, and, importantly, their effects in the human body.
The resulting compound is classified into one of four categories, depending on method of production.
Class I: No ammonium or sulfites.
Used in high-proof alcohols.
Class II: Sulfites added, no ammonium.
Used in some cognac, sherry and vinegars.
Class III: Ammonium compounds added, no sulfites.
Used in some beers, sauces, and candy.
Class IV: Ammonium and sulfites added.
Used in soft-drinks.
Caramel color has an odor of burnt sugar, so Caramel color can not only provide an appealing color, but also enhance the original flavor and taste of foods.
Not quite the same as the tasty caramel we get when we melt sugar, caramel color—seen on the ingredient labels of many popular soft-drinks—is an artificial coloring agent recently brought into the public spotlight for its suggested negative health effects.
Caramel has been used in the personal care industry as a natural colorant for many years.
As the demand for natural personal care products continues to grow, the interest in caramel as a personal care colorant also has grown.
Caramel is an approved colorant in the United States and Europe, yet little is understood about how the performance of caramel can differ in personal care formulations.
All caramels are not the same.
They are divided into four classes: plain or caustic caramel (Class I); caustic sulfite caramel (Class II); ammonia caramel (Class III) and sulfite ammonia caramel (Class IV).
Caramel colors are amorphous, brownish materials resulting from the carefully controlled heat treatment of food grade carbohydrates in the presence of small amounts of food grade acids, alkalis or salts.
The chemistry of caramelization is complex and difficult to explain in brief.
Modern caramel color production is carried out in a heat controlled, closed vessel where a caramelization reaction occurs.
In this reaction, the sugars, i.e. large carbohydrate molecules, are dehydrated, then either reduced in size to simple sugars under the influence of acid, heat and/or pressure; condensed or recombined; or polymerized into complex color molecules of varying molecular weight.
Since caramel is a complex aggregate of degraded sugars, it is also difficult to illustrate using simple structural terms. Caramel can be considered a reduction of complex carbohydrates to smaller carbohydrates that are then combined into larger polymeric colored ingredients and by-products.
Similar examples of complex by-products created by mixing reactant products include roasted coffee and broiled meats.
