Scope

This Standard is applicable to the food additive BIXIN (bixin) obtained by taking the
outer seed coat of annato (Bixa orellana L.) seeds as raw materials, and through
extracting a solvent or cold weak alkaline aqueous solution and refining; as well as the
food additive BIXIN (norbixin) obtained through hydrolysis of the hot alkaline aqueous
solution and refining. The used solvents include acetone, methanol, ethanol, n-hexane,
isopropanol, ethyl acetate, basic ethanol and/or carbon dioxide.
