 The
use of food emulsifier began with the production of margarine as monoglyceride
and lecithin. These compounds were commonly called emulsifiers.
After that quite different functions were found and emulsifiers have since
been used in starchy foods such as breads, and dairy products like ice
cream. Nowadays, emulsifiers are also used in Japanese-foods like Tofu
and minced fish products.
Why do bread and Tofu need emulsifiers? Generally speaking, an emulsifier
is as a compound with emulsifying effects, however, actually it has various
functions. For example:
To modify oil crystal and prevent water spattering in cooking.
In ice cream, an emulsifier does not promote emulsification, but rather
destroys emulsion to stabilize foam and to make a product with smooth
texture and shape keeping property.
In bread, an emulsifier reacts with proteins to make a smooth easy-rising
dough with no relation to emulsification. It also acts on starch to make
bread soft.
