StrainBaker's yeast
Description5-(2-Hydroxyethyl)-4-methylthiazole is a thiazole, a type of nitrogenous heterocycle compound. Thiazoles are found in different processed foods and are the products of the Maillard reaction, which involves an amino acid and a reducing sugar. Thiazoles are volatile compounds responsible for popcorn, roasted, and peanuts aromas. 5-(2-Hydroxyethyl)-4-methylthiazole is also a substrate in thiamin (vitamin B1) biosynthesis.
