【摘要】 气质联机分析了维生素B1(硫胺素)微波炉中火加热5分钟的挥发性产物, 鉴定出26种含硫化合物,结构类型包括噻吩、噻唑、硫取代呋喃、脂肪族含硫化合物、含硫羰基化合物等, 其中2-甲基-3-呋喃硫醇,2-乙酰基噻吩等9种化合物含有肉香味含硫化合物特征结构单元.更多还原

【Abstract】 Volatiles from thermal degradation Vitamin B1 (thiamin) in a microwave oven were trapped and analyzed by GC/MS. Twenty six sulfur containing compounds with structural characteristics of thiophene, thiazole, furyl sulfide, acetyl sulfide,aliphatic sulfide were identified. And nine of them such as 2-methyl-3-furanthiol and 2-acetylthiophene, which bear the specificmeaty structural unit, were expected to possess the meaty flavor and contribute more to the aroma of Vitamin B1 degradationproducts under microwave oven heating.更多还原
