Glycerin fatty acid ester

Glycerin fatty acid ester is an additive used mainly in the sake brewing process. It improves the sabake of steamed rice (the way the grains separate, which depends on the rice's condition and stickiness), making it easier to move steamed rice by pneumatic conveyance and to carry out koji making. Specifically, it keeps the steamed rice grains from sticking to one another so that the rice can be handled evenly, which improves working efficiency when making koji. This ester is approved as a food additive and its safety has been confirmed, but it is important to use it in an appropriate amount.
