What is Sorbitan Monostearate (E491) in food and yeast? Uses and Safety
sorbitan monostearate (abbreviation SMS), or Span 60, is an emulsifier esterified from sorbitol and stearic acid with the European food additive number E491. This ingredient is mostly used in baking yeast by improving the activity of instant dry yeast when the yeast is rehydrated before use.

How is Sorbitan monostearate made?
Generally, sorbitan monostearate can be made from direct esterification of sorbitol and stearic acid. Sorbitan tristearate (E492) would be generated in the production if too much stearic acid is involved.

Sorbitan monostearate (abbreviation SMS), or Span 60, is an emulsifier esterified from sorbitol and stearic acid with the European food additive number E491. This ingredient is mostly used in baking yeast by improving the activity of instant dry yeast when the yeast is rehydrated before use.

Sorbitol

Sorbitol is a sugar alcohol with a sweet taste and can be used as a sugar replacement and humectant in chewing gum, mints, cookies, bread, and cakes. It is commonly made from starches of corn and potato and follow the hydrogenation process.

Stearic Acid

It is a common saturated fatty acid found in nature both in animal fats/oils and vegetable oils. It can also be used in the production of soaps, cosmetics, and detergents.

The commercial food grade stearic acid may contain 48.7–50.0% palmitic acid.

As sorbitol has six hydroxyl groups and that’s why sorbitan monostearate may also contain palmitic acid esters of sorbitol, sorbitan and isosorbide besides sorbitol, sorbitan, and isosorbide esters of stearic acid.

Properties

What’re the Uses of Sorbitan monostearate?
Sorbitan monostearate is used as an emulsifier, commonly together with polysorbates to keep water and oil mixed in many food products.

It is commonly used in instant dry yeast, fat and oil emulsions, desserts, food supplements, cake, spread, margarine, coffee whiteners, and so on.

The following are its main uses and functions in food:

Dry yeast: maintain the moisture, increase the shelf life of dry yeast, and help the rehydration of yeast cells before blended with other dough ingredients.
Ice cream: promote emulsifying of dairy fat, prevent the formation of ice crystals, and improve the mouthfeel.
Margarine: improve emulsion stability and reduce sandiness.
Whipping cream: improve foam volume and contribute to a nice and stiff foam.
Bread & Cake: increase the loaf volume and improve the texture of bread and cake.
Confections and chocolate: stabilize the emulsion of oils and fats.
Meanwhile, it can be condensed with ethylene oxide to synthesize polyoxyethylene (20) sorbitan monostearate (polysorbate 60), which is also a food emulsifier.

Is Sorbitan monostearate Safe to Eat?
Yes, it almost has no side effects and the safety has been approved by the U.S. Food and Drug Administration (FDA) and European Food Safety Authority (EFSA), as well as the Joint FAO/WHO Expert Committee on Food Additives (JECFA).

FDA
Sorbitan monostearate may be safely used as an emulsifier in the following food, sometimes together with polysorbate (60, 65, 80) (1):Whipped edible oil topping
Cakes and cake mixes, icings and fillings
Nonstandardized confectionery coatings and standardized cacao products
Edible vegetable fat-water emulsions in beverage coffee
It can also be used as a rehydration aid in the production of active dry yeast with the maximum usage 1%. It may also be safely used in mineral premixes and dietary supplements for animal feeds. (2)

EFSA
Sorbitan monostearate (E491) is listed in Commission Regulation (EU) No 231/2012 as an authorised food additive and categorized in “ additives other than colours and sweeteners” (3).

Safety re-evaluation in 2017
EFSA changed the ADI of 25 mg/kg bw per day set by The Scientiﬁc Committee on Food (SCF) in 1974 and established a group ADI of 10 mg/kg bw per day for sorbitan esters (expressed as sorbitan) , and the ADI of sorbitan monostearate is 26 mg/kg bw per day. (4)

Approved uses
Its application is listed together with other sorbitan esters: sorbitan tristearate (E492), sorbitan monolaurate (E493), sorbitan monooleate (E494) and sorbitan monopalmitate (E495) and with the maximum use levels “5000-10000 mg/kg” while the use level in dry yeast and yeast for baking is “quantum satis”.

Frequently asked questions
Is SMS Halal?
Yes, it is is a synthetic ester that would be halal complying with the Muslim policy if the fatty acid stearic acid derived from vegetable oils instead of animal origins.

Is SMS Vegan?
Yes, it is corn derivative and vegan if the raw material stearic acid from vegetable oils as the manufacturing process without the use of animal matter or products derived from animal origin.

However, some manufacturers may use stearic acid from animal sources. Therefore, vegetarians should avoid it.

Nonionic surfactants are surface active agents which do not dissociate into ions in aqueous solutions, unlike anionic surfactants which have a negative charge and cationic surfactants which have a positive charge in aqueous solution. Nonionic surfactants are more widely used as detergents than ionic surfactants because anionic surfactants are insoluble in many hard water and cationic surfactants are considered to be poor cleaners. In addition to detergency, nonionic surfactants show excellent solvency, low foam properties and chemical stability. It is thought that nonionic surfactants are mild on the skin even at high loadings and long-term exposure. The hydrophilic group of nonionic surfactants is a polymerized alkene oxide (water soluble polyether with 10 to 100 units length typically). They are prepared by polymerization of ethylene oxide, propylene oxide, and butylene oxide in the same molecule. Depending on the ratio and order of oxide addition, together with the number of carbon atoms which vary the chemical and physical properties, nonionic surfactant is used as a wetting agent, a detergent, or an emulsifier. Nonionic surfactants include alcohol ethoxylates, alkylphenol ethoxylates, phenol ethoxylates, amide ethoxylates, glyceride ethoxylates (soya bean oil and caster oil ethoxylates), fatty acid ethoxylates, and fatty amine ethoxylates. Another commercially significant nonionic surfactants are the alkyl glycosides in which the hydrophilic groups are sugars (polysaccharides).

The term sorbitan describes the anhydride form of sorbitol, whose fatty acids are lipophilic whereas sorbitol body is hydrophilic. This bifunctionality in one molecule provides the basic properties useful in cleaners, detergents, polymer additives, and textile industry as emulsifiers, wetting agents, and viscosity modifiers. Sorbitan esters are rather lipophilic (or hydrophobic) surfactants exhibiting low HLB (Hydrophilic-Lipophilic Balance) values; having an affinity for, tending to combine with, or capable of dissolving in lipids (or water-insoluble). While, the ethoxylated sorbitan esters are hydrophilics exhibiting high HLB values; having an affinity for water; readily absorbing or dissolving in water. The type of fatty acid and the mole number of ethylene oxide provides diverse HLB values for proper applications.

Sorbitan monostearate has been approved by the European Union for use as a food additive (emulsifier) (E number: E 491)
HLB numbers describe following characterestics:
<10 : Lipid soluble (or water-insoluble)

DESCRIPTION OF SORBITAN MONOSTEARATE

Sorbitan monostearate is an ester of sorbitol and stearic acid.

The sorbitol end of the molecule is very soluble in water. The stearic acid end is soluble in fats. These properties make the molecule very good at making emulsions of oil and water.

Sorbitan monostearate is sometimes known as a synthetic wax.Sorbitan monostearate is a fatty acid that has many uses in the food industry and in health and beauty care products. Sorbitan monostearate is not a health supplement.

Sorbitan monostearate is used as a food additive that works as a surfactant, or blender. Other food uses are as an emulsifier, wetter, disperser, flavor enhancer or other form of food additive.

Sorbitan monostearate is used as an emulsifier and as a non-ionic surfactant. Sorbitan monostearate is used in cosmetics, pharmaceuticals and food preparation.

Not all types of physical activity are suitable for everyone. Users take challenges and training advice at Sorbitan monostearate own personal risk.

Stearic acid was the hm (74-82), no longer an active mh. Food emulsifier, stabiliser, defoaming agent, flavouring and flavour modifier, rehydration agent for active dried yeast, coating for fruit and vegetables and other food uses Sorbitan monostearate (also known as Span 60) is an ester of sorbitan (a sorbitol derivative) and stearic acid and is sometimes referred to as a synthetic wax. It is primarily used as an emulsifier to keep water and oils mixed. Sorbitan monostearate is used in the manufacture of food and healthcare products, and is a non-ionic surfactant with emulsifying, dispersing, and wetting properties.

Solid sorbitan ester anti-fog additive effective for use in greenhouse films based on LDPE, LLDPE, EVA (low VA content), and PVC. Anti-fog performance can be significantly enhanced by use in combination with SABO®STAT A 300. It is also suitable for use as an anti-static additive in PVC and as a dispersing agent for pigments in plastic masterbatches and compounds.
