용도

일반 설명

3-Mercapto-2-butanone is a sulfur-containing flavor compound mainly found in meat and meat products. It is formed by the Maillard reaction between sugars and cysteine or thiamin, which are known precursors for meat-like flavorings.

제조 및 합성 방법

제조 방법

From 2,4,5-trimethyl-2-ethyl-3-thiazoline with butyl and hydrolysis; from oxo-compound with sulfur or polysulfides and ammonia at room temperature.
