新型食品添加剂谷氨酸钙的简述

Brief introduction of the new food additive——Calcium Diglutamate

谷氨酸钙是一种新型的食品添加剂,它可以代替食盐改善食物口味,补充钙质。为了普及推广谷氨酸钙,分别介绍了食盐的作用和谷氨酸钙的作用,通过加入谷氨酸钙可使汤中的含盐量从150 mM（1.03%）降低至50-85 mM（0.34%-0.58%）,香肠中含钠量从0.69%降低至0.12%,食物口感和滋味没有改变,因此,谷氨酸钙在生产低盐食物上有很大的潜力。

Calcium Diglutamate （CDG） is a kind of new safe food additive. As a substitute of salt, CDG can enhance food flavor and implement calcium to body. The functions of salt and CDG are introduced respectively in order to popularize CDG. The salt in the soup with CDG can be reduced from 150 mM （ 10.3% ） to 50- 85 mM （ 0.34% - 0. 58% ） without significant deterioration of taste. The adding of CDG to sausages can lower Na from 0.69% to 0.12% while the flavor doesnt change. Therefore, CDG has a great prospect in the production of low - salt foods.
