설명

일반 설명

Natural occurrence: Asparagus, beef, sake, Virginia tobacco, wheat bread.

Pyruvic acid is the key component formed during the hydrolysis of flavor-precursors called S-alk(en)yl-L-cysteine-sulfoxides in onion tissues by allinase during maceration or chopping. The amount of pyruvic acid formed is used as a measure for onion pungency.
