摘    要:在红曲霉发酵酿造茶酒的原料中添加制茶下脚料,实验对比测定了发酵前后各营养成分的变化,结果表明:发酵前物料中各营养含量分别为,总糖(302.2±3.29) mg/g,还原糖(126.3±7.46)mg/g,多糖(175.9±9.05) mg/g,粗纤维27.1%,氮(40.64±1.06) mg/g,游离氨基酸(47.04±0.75) mg/g。发酵后物料中总糖(199.1±1.64) mg/g,还原糖(29.07±0.34) mg/g,多糖(170.0±1.30) mg/g,粗纤维18.8%,氮(37.02±0.86) mg/g,游离氨基酸为0 mg/g。发酵前后物料总重量利用率39.4%,各营养物质的转化率分别为总糖60.06%,还原糖86.01%、多糖3.35%、粗纤维30.62%、氮8.91%、氨基酸为100%。发酵茶酒的酒精度达到13%。

Abstract:Add the tea scraps in tea wine materials of Monascus fermented. Nutrient compositons were compared. The results showed that the raw material contain total sugar (302.2±3.29) mg/g, reducing sugar(126.3±7.46)mg/g,polysaccharides (175.9±9.05) mg/g, crude fiber 27.1 %, nitrogen (40.64±1.06) mg/g, free amino acid (47.04±0.75) mg/g. After fermentation, the material contain total sugar (199.1± 1.64) mg/g, reducing sugar (29.07±0.34) mg/g,polysaccharides(170.0±1.30) mg/g,crude fiber 18.8 %,nitrogen (37.02±0.86) mg/g, free amino acid 0 mg/g. The output coefficient of this processing for material was 39.4 %, total sugar 60.06 %,reducing sugar 86.01 %, polysaccharides 60.06 %, crude fiber 30.62 %, nitrogen 45.30 %, amino acid 100 %. The alcohol content for tea wine was 13 %.
Keywords:Monascus  fermentation  tea scraps  nutrients  utilization
