E492 - Sorbitantristearat

Origin

Sorbitan tristearate (E492) is a non-ionic surfactant and emulsifier derived from sorbitol and stearic acid. Sorbitol is a sugar alcohol found naturally in some fruits, but commercially it is produced by the catalytic hydrogenation of glucose. Stearic acid is a saturated fatty acid commonly obtained from vegetable oils, although animal fats can also be a source. The esterification of sorbitol with stearic acid results in sorbitan tristearate.

Usage

E492 is primarily used in the food industry as an emulsifier, stabilizer, and thickener. It helps to blend oil and water-based ingredients, preventing separation and maintaining a consistent texture. It is commonly found in chocolate and chocolate coatings to prevent fat bloom (the white coating that can appear on chocolate). Other applications include baked goods, icings, whipped toppings, and processed foods. It can also be used in non-food applications such as cosmetics, pharmaceuticals, and industrial products.

Side Effects

Sorbitan tristearate is generally considered safe for consumption at the levels typically used in food. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has established an Acceptable Daily Intake (ADI) "not specified", meaning that, based on available data, the total dietary intake of the food additive does not represent a hazard to health. However, as with many food additives, excessive consumption may cause gastrointestinal discomfort in sensitive individuals. There are no significant concerns regarding carcinogenicity, genotoxicity, or reproductive toxicity at normal usage levels. Individuals with specific sensitivities to sorbitol or stearic acid should exercise caution, although allergic reactions are rare.

Regulatory Status

Sorbitan tristearate (E492) is approved for use as a food additive in many countries, including the European Union (EU) and the United States. In the EU, it is subject to specific purity criteria and labeling requirements. In the United States, it is regulated by the Food and Drug Administration (FDA) under specific conditions of use. The regulatory status and permitted uses may vary depending on the specific jurisdiction.
