The main purpose

It has special effects on preventing the production of aflatoxin, various molds, and gram-negative bacilli, but it is almost ineffective against yeast.  EEC regulations can be used for dairy products, bakery products, cheese, etc. It is also used as a sticky substance inhibitor for beer and the like. In the food industry as leavening agents, dough conditioners, buffers, tissue modifiers, curing agents, nutritional supplements, chelating agents. Such as baked products, cake raising agent. Bread, biscuits, co-enzymes, buffers, pectin curing agent (gel effect), yeast food meat product tissue improver and so on. For brewing, increase saccharification and increase fermentation capacity。

Dosage

Antibacterial effect is affected by the pH of the environment. The minimum inhibitory concentration was 0.01% at pH 5.0 and 0.5% at pH 6.5.
