Roles Classification
Biological Role(s): food anticaking agent
An anticaking agent that is used to reduced the tendency of particles of food to adhere to one another.
plant metabolite
Any eukaryotic metabolite produced during a metabolic reaction in plants, the kingdom that include flowering plants, conifers and other gymnosperms.
antimicrobial agent
A substance that kills or slows the growth of microorganisms, including bacteria, viruses, fungi and protozoans.
raising agent
A food additive which liberates gas so as to increase the volume of a dough or batter, resulting in a lighter and softer finished product.
