摘要
酿酒副产物丟糟的产生量大,丢糟成分复杂,含水量高,不易储存。稻壳等发酵填充物不易利用,暴露在空气中容易霉烂,对大气、水体、土壤都有一定的影响,丢糟的利用存在一定的困难。同时丟糟中还含有丰富的粗蛋白、粗纤维、粗脂肪、氨基酸、维生素和多种微量元素,营养丰富,具有非常高的开发利用价值。在对国内外丟糟的综合利用研究基础上,提出了通过丟糟提取木聚糖、甘油、有机酸和氨基酸等高附加值的产品,生产饲料、醋、酱油和食用菌等食品,生产生物肥、改良土壤等三个方面的综合利用途径,充分利用丟糟中的各种营养成分,提高丢糟的剩余价值,从节能环保的角度实现对丟糟的综合利用,创造较大的经济效益和社会效益。
As one part of by-product,there is a lot of distiller＇s grain which owns complicated composition,has high moisture content and is kept difficultly. There are some fermentation fillers just like rice husk which are hard to use and are easy to become mouldy in the air,as a result,which is bad for air、water and soil. There are some difficulties exist for the use of distiller＇s grain. Meanwhile,Distiller＇s grain contains abundant crude protein,crude fiber,crude fat,amino acid,vitamin,multiple microelement. Distiller＇s grain is nutritious and has high development and utilization value. In the paper,on the basis of research on the integrated utilization of distiller＇s grain at home and abroad,products with high additional value such as xylan,glycerol,organic acid and amino acid are extracted from distiller＇s grain,foods such as feed,vinegar,soy sauce and edible mushrooms are produced,bio-fertilizer is produced and soil condition is improved. The variety of nutritional ingredients of distiller＇s grain should be made good use of in order to improve surplus value of distiller＇s grain. At last,from the perspective of environmental protection,comprehensive utilization of distiller＇s grain is realized,meanwhile a lot of economic benefit and social benefit is created.
