A new method for analysis of Sorbitan Tristearate (STS) in vegetable oils and fats has been developed. 
The method is based on isolation and hydrolysis of STS compounds in a silica cartridge. 
The polyalcohols are eluted from the silica cartridge and the final separation and quantitation are done by high-performance liquid chromatography and refractive index detection. 
Linearity, precision, and recovery satisfy general demands on quantitative methods. 
The detection limit and the quantitation limit are well below the concentrations normally used to attain functional effects of STS in vegetable oils and fats.

Description:
Sorbitan Tristearate is produced by the esterification of Sorbitol with commercial edible fatty acids and consists of approximately 95% of a mixture of the esters of Sorbitol and its mono and di-anhydrides.
Sorbitan Tristearate is light cream to tan coloured, hard, waxy solid with a slight characteristic odour and bland taste.

Applications in Food:
Sorbitan Tristerate is free of Palm-oil and serves as a good food additive for Halal and Kosher preparations too. 
E492 has many other applications in food include:

Chocolates:
Sorbitan Tristearate is an effective emulsifier to retard fat bloom in chocolate. 
Fat used in chocolate, particularly cocoa butter, forms as a tightly packed β’ polymorph/crystal which is an unstable crystal but is vital for the functional and aesthetic quality of chocolate. 
If chocolate is not tempered properly or is exposed to excessive heat, these β’ crystals convert to β crystals which are less tightly packed but are more stable. 
These β crystals tend to migrate to the surface causing fat bloom to occur and also having a negative impact on the aesthetics of the chocolate.

Sorbitan Tristearate’s structure mimics the β’ crystals and bonds with such fat crystals and retards their conversion to the less desirable β crystals.

Crystal Inhibitor in Palm Olein and Coconut Oil:
Sorbitan Tristearate is used as a crystal inhibitor in oils which contain fractions that harden faster during colder temperatures making the oils look cloudy. 
Sorbitan Tristearate is perceived by many as deteriorated oil which it actually is not,it is just aesthetically unacceptable.

The addition of Sorbitan Tristearate retards the harder fractions from nucleating at lower temperatures and causing cloudiness in oils.

Margarine and low-fat spreads:
Sorbitan Tristearate has a structure more similar to a triglyceride than to an emulsifier.
In margarine and low-fat spreads textural defects can occur quite rapidly due to the change of fat crystals from β’ to β form. β crystals have a sandy texture and can lead to poor mouthfeel and aesthetics. 
STS retards this change from one crystal to another and keeps the crystal size of the fat in control to slow down nucleation and sandiness.

The Sorbitan esters are the fatty-acid esters of hexitol anhydrides derived from sorbitol. 
Esterification with a fatty acid derivatives normally yields the ester at the terminal (primary) alcohol group (e.g., Sorbitan Oleate). 
Sorbitan esters are water insoluble. 
The sorbitan derivatives as a class are excellent emulsifiers.

ABSTRACT
The formation and stabilization of fat crystals in palm oil (PO) by the templating effects of sorbitan tristearate (STS) and sucrose stearate (S-370) were examined. 
We observed that the crystallization mechanism occurred via heterogeneous nucleation, which was induced by co-crystallization or seeding, after the addition of STS or S-370, respectively. 
Overall, both emulsifiers, STS and S-370, caused an increase in the hardness of PO, which was related to changes in the microstructure. 
In addition, the intensity of this effect was shown to be dependent on the emulsifiers concentration. 
In differential scanning calorimetry analysis, S-370 proved to be associated predominantly to the crystallization of high-melting triacylglycerols (TAGs), while STS showed to actuate the crystallization of high and low-melting TAGs. 
Moreover, the addition of STS improved the polymorphic stability of the PO, while the use of S-370 resulted in a soft texture at lower temperatures.

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 Tristearate While at a restaurant, you order a meal which includes a salad, followed by a soup, a club sandwich, and ice cream for dessert. 
These four food items have more in common than you think; the salad dressing on your salad and the mayonnaise on your sandwich and your soup and ice cream all contain sorbitan tristearate. 
But what is sorbitan tristearate that is found in so many of the foods that you eat everyday? 
Sorbitan tristearate is a non-toxic product that is used in foods, among other products. 
Sorbitan Tristearate  is used as a substitute for sorbitan stearate and conforms to Food and Drug Administration requirements. 
The main focus of this paper will be the chemical and physical properties of sorbitan tristearate, Sorbitan Tristearate structure, the use it has as a food additive, how it is manufactured, and the toxicology of the product. 

Sorbitan tristearate is manufactured. 
Sorbitan tristearate is done so by "reacting edible commercial strearic acid with sorbitol. 
Sorbitan tristearate usually contains associated fatty acids, mainly the fatty acid palmitic". 
Sorbitan tristearate can be safely used if the sorbitan tristearate is manufactured with stearic acid and sorbitol to "yield a mixture of esters". 
If these components are combined correctly, the sorbitan tristearate has been manufactured properly and is regulatory.

Definition:
Sorbitan tristearate is an emulsifier and stabilizer made from sorbitol esters and stearic acid. 
Sorbitan tristearate is used particularly in chocolates to maintain colour and shine and prevent blooming, and in margarine and cooking oils to maintain appealing texture.

Health considerations:
At the levels expected with normal consumption, no negative effects have been attributed to sorbitan tristearate.

May be found in:
Bakery products, toppings and coatings, fat emulsions, milk and cream analogues, beverage whiteners, edible ices, desserts, sugar confectionery, chocolate, emulsified sauces, dietetic foods
