supplement, emulsifier, and stabilizer e.g. it is applied as
leavening agent for flour, cake, pastry, bakery, as quality
modifier for bread, and fried food. Also be applied in biscuit,
milk powder, drinks, ice cream as nutrient supplement or quality
improver. In pharmaceutical industry, it is often used as an
additive in the producing of Calcium Tablet or other tablets. In
daily chemical industry-toothpaste, it is used as friction
agent.
