Administration route: Oral. Commonly used amount and the maximum amount: FAO/WHO(1984, g/kg) : Margarine 5; Cold drink 10. GB 2760-2001: Lactic acid bacteria drinks, vegetable protein drinks, ice cream, ice cream bars, popsicles, potato chips, fried snacks and starch and seasonings used for fried snacks, all 10g/kg. Source and Preparation: The synthesis is divided into two steps. The first step is to add 5kg sodium hydroxide into 500kg refined glycerin at 200-300 °C and in the presence of a small amount of alkaline catalysts (such as NaOH, KOH, LiOH, etc.), steam away the water, condense at 260°C for 24h, and then add CO2 gas to stir and remove the generated water. Inert gas is then injected at 220 ~ 225°C and 267kPa to steam off the unreacted glycerol, and finally cooled under nitrogen protection. In the second step, 450kg stearic acid and 485kg glycerin were mixed and stirred, esterified for 2h at 220-230 °C, and then cooled in CO2 airflow to separate a small amount of unreacted glycerin to obtain the product.
