The Function of Polysorbate 80

What is polysorbate 80 in food Polysorbate 80 uses in pharmaceuticals is a synthetic non-ionic emulsifier, widely used in cosmetics, food and pharmaceutical preparations. Its industrial manufacturing method is: under the condition of alkali catalysis, the addition reaction of ethylene oxide with sorbitol fatty acid esters and sorbitol fatty acid esters is carried out, in which every 1mol of sorbitol or corresponding sorbitol anhydride is added to 20mol of epoxy ethane. 1. Types of polysorbates The most common types of polysorbates are polysorbate 20, 40, 60, 65 and 80. In addition, there are also polysorbate 21, 61, 81 and 85. Polysorbate at room temperature is paste-like or in a form of sticky oily liquid with a color between light beige and light yellow. Polysorbate has good thermal stability. Because the long polyoxyethylene chain, the hydrophilic group is the dominant component of the entire emulsifier molecule. 2. Brief int...
