摘要:

以豆粕酶解物为原料,通过美拉德反应制备猪肉香精,并用GC-MS对反应产物中挥发性风味成分进行分析。结果表明:以豆粕酶解物为原料的美拉德反应较佳配方为半胱氨酸添加量0.5g/100mL、还原糖添加量6g/100mL、葡萄糖和木糖的配比为1:3(m/m)、VB1添加量0.3g/100mL、VC添加量 0.20g/100mL,最佳工艺条件为反应pH8.0、反应温度100℃、反应时间20min,在此条件下感官评分达到4.68;经GC-MS分析共分离鉴定出29种化合物,其中2-甲基-3-呋喃硫醇、糠醛、2-乙酰基吡啶、3-甲基丁醛、甲基吡嗪等对肉香味具有重要意义。

Abstract:

Pork-flavor essence was prepared by Maillard reaction using the soybean meal hydrolysate prepared in this
laboratory and the volatile compounds of the pork flavor essence was identified by GC-MS. The optimum Maillard
reaction conditions were as follow: 0.5 g of L-cysteine, 6 g of reducing sugar, 0.3 g of VB1 and 0.2 g of VC per 100 mL
of hydrolysate, 1:3 of glucose-to-xylose ratio, pH 8.0, 100 ℃ and 20 min. The resulting essence scored 4.68 in sensory
evaluation. A total of 29 volatile compounds were identified from this synthetic essence. Some identified compounds made
an important contribution to the pork flavor, such as 2-methyl-3-furanthiol, furfural, 1-(2-pyridinyl)-ethanone, 3-methylbutanal,
methyl-pyrazine, etc.
