The Many Uses of E509 (Calcium chloride) in Food
Fundamentally E509 (Calcium chloride) is a desiccant and is often used as a firming agent.
That is, it helps keep foods from becoming mushy when they sit on store shelves – particularly canned foods.
You’re likely to find it in almost any canned fruit or vegetable, as it does a lot to extend the shelf lives of those foods.
However, that’s just the start of the usefulness of E509 (Calcium chloride).
Another extremely commonplace use of E509 (Calcium chloride) is when making cheese.
At a basic level, it acts as a firming agent here too – helping the cheese curds clump together and be more stable once they do.
Beyond that, it’s also highly useful for regulating the process of separating curds and whey.
Small amounts of E509 (Calcium chloride) can be added to milk, changing both its calcium content and its pH level, which in turn will change the properties of the cheese which is made.
The substance is also used in the making of tofu, particularly firm tofu, in a similar fashion.
E509 (Calcium chloride) is also commonly seen among brewers, as one of many “brewing salts” which can be added to affect the type and quality of the beer produced.
It can help correct for unbalanced mineral levels, as well as – again – altering the pH of the beer.
This is vital for creating a stable product!
One of the more interesting properties of E509 (Calcium chloride) is that when it’s combined with sodium alginate (another safe food additive) it can make liquids combine into small semi-solid spheres.
This is used for making fake caviar, as well as other novelty foods.
Applications of E509 (Calcium chloride):

Physical Properties of E509 (Calcium chloride) and Hydrates:
E509 (Calcium chloride) has got various physical properties.
Anhydrous E509 (Calcium chloride) and the lower hydrates release a large amount of heat when dissolved in water (negative values for Heat of Solution).
CaCl2 as a Chemical:
Decomposes on heating.
This produces toxic and corrosive fumes of chlorine.
The solution in water is a weak base.
Attacks zinc in the presence of water.
This produces flammable/explosive gas (hydrogen).
Dissolves violently in water with liberation of much heat.
Calcium is essential to the function of the nervous, muscular and skeletal systems.
Calcium also plays a part in cardiac function, renal function, respiration and blood coagulation.
Calcium ions increase the force of myocardial contraction.
In response to electrical stimulation of muscle, calcium ions enter the sarcoplasm from the extracellular space.
Calcium ions contained in the sarcoplasmic reticulum are rapidly transferred to the sites of interaction between the actin and myosin filaments of the sarcomere to initiate myofibril shortening.
Thus, calcium increases myocardial function.
Calcium's positive inotropic effects are modulated by its action on systemic vascular resistance.
Calcium may either increase or decrease systemic vascular resistance.
In the normal heart, calcium's positive inotropic and vasoconstricting effect produces a predictable rise in systemic arterial pressure.
Solubility of E509 (Calcium chloride):
Although E509 (Calcium chloride) is highly soluble in water at ordinary temperatures, crystallization will occur under certain temperature and concentration conditions.
Concentrated solutions of E509 (Calcium chloride) have a marked tendency to supercool; i.e., the temperature of the solution may fall several degrees below the phase boundary without crystallization taking place.
When crystals finally form in these supercooled solutions, the temperature of the mixture will rise to the limit defined by the phase diagram.
Crystallization points of commercial E509 (Calcium chloride) brines will differ slightly from those of pure E509 (Calcium chloride).
Moisture Absorption of E509 (Calcium chloride):
E509 (Calcium chloride) is both hygroscopic and deliquescent.
Thus, under common ambient conditions, solid material will absorb moisture from the air until it dissolves.
E509 (Calcium chloride) solutions will absorb moisture until an equilibrium is reached between the water vapor pressure of the solution and that of the air.
If the humidity of the air increases, more moisture is absorbed by the solution.
If it decreases, water evaporates from the solution into the air.
Surface tension is the force on the surface of a liquid that tends to diminish the surface area to a minimum.
It is a result of differences in intermolecular attraction at the surface and in the interior of the liquid.
At the surface, all the molecules are attracted inward; in the interior, the attraction is the same in all directions.
Surface tension has an important effect on the wetting and penetration abilities of a liquid, and on its ability to form emulsions.
The lower the surface tension, the greater the liquid’s wetting and penetration ability, and its ability to form an emulsion.

When storing E509 (Calcium chloride), keep it dry, concealed and away from zinc (since the two substances can react if mixed). If E509 (Calcium chloride) happens to spill, the IPCS recommends safely sweeping it into covered containers, moistening the salt if needed to more easily stow it.
Preperation of E509 (Calcium chloride):
In much of the world, E509 (Calcium chloride) is derived from limestone as a by-product of the Solvay process, which follows the net reaction below:
2 NaCl + CaCO3 → Na2CO3 + CaCl2
North American consumption in 2002 was 1,529,000 tonnes (3.37 billion pounds).
In the US, most of E509 (Calcium chloride) is obtained by purification from brine.
As with most bulk commodity salt products, trace amounts of other cations from the alkali metals and alkaline earth metals (groups 1 and 2) and other anions from the halogens (group 17) typically occur, but the concentrations are trifling.
Occurrence of E509 (Calcium chloride)
E509 (Calcium chloride) occurs as the rare evaporite minerals sinjarite (dihydrate) and antarcticite (hexahydrate).
Another natural hydrate known is ghiaraite - a tetrahydrate.
The related minerals chlorocalcite (potassium E509 (Calcium chloride), KCaCl3) and tachyhydrite (calcium magnesium chloride, Ca Mg2Cl6·12H2O) are also very rare.
So is true for rorisite, CaClF (E509 (Calcium chloride) fluoride).
E509 (Calcium chloride) Ice Melt
When it comes to finding the most powerful ingredient for melting ice, E509 (Calcium chloride) ice melt is generally the top choice.
E509 (Calcium chloride) is a chemical used for numerous purposes, including refrigeration, dust control, and melting ice.
E509 (Calcium chloride) is available in liquid formulations, but as an ice melter it is usually provided in pellet or flake form.
If you are thinking of using E509 (Calcium chloride) on your residential or commercial property but are unsure of its benefits compared to other ice melters, the following information will help you make an informed decision.
E509 (Calcium chloride) is widely used by commercial businesses for melting ice and is the preferred choice over common rock salt.
It has several key advantages, the most important being the following:
E509 (Calcium chloride) has the most powerful and quickest melting action on the market today.
For ice to melt, deicing chemicals must first reach the pavement and dissolve into brine.
E509 (Calcium chloride) absorbs moisture from the atmosphere as opposed to relying on the little water that snow has to offer.
As it returns to liquid state and mixes with water, E509 (Calcium chloride) also becomes exothermic—it releases thermal energy that further helps in melting the ice surrounding it, which in turn allows it to release more thermal energy.
E509 (Calcium chloride) currently holds the record for melting ice at the coldest temperatures.
While potassium chloride can melt ice down to approximately -13°F (-25°C) and rock salt down to -10°F (-23.3°C), E509 (Calcium chloride) can melt down to -25°F(-31.7°C).
This makes E509 (Calcium chloride) ice melt the most effective ice melter during harsh winter conditions and heavy snowstorms.
E509 (Calcium chloride) in its anhydrous form is an economical drying agent and very important for drying processes in laboratories.
Those are for example: drying of liquids and neutral gases.
It is also a very good drying agent for a wide variety of solvents.
E509 (Calcium chloride) is suitable for drying acetone, ethers, numerous esters, aliphatic, olefinic, aromatic and halogenated hydrocarbons, and neutral gases.
Since E509 (Calcium chloride) is also available in granular form, it is often used in drying tubes.
Note: E509 (Calcium chloride) is not suitable for drying ammonia, amines, alcohols, phenols, aldehydes, ketones and some esters because these substances are bound by CaCl2.
E509 (Calcium chloride) has a drying capacity up to 98%.
It binds the water through crystallization and can be regenerated by warming.
Regenerate at 250°C for at least 1 hour.
