摘  要:
目前苜蓿Medicago sativa叶蛋白提纯为食用叶蛋白需要经过二次加工,进行脱色、去腥工艺,且苜蓿叶蛋白的脱色、去腥技术尚处于研究阶段,工艺还不成熟。为此,将苜蓿叶蛋白在提取阶段直接分离出不同用途的绿白叶蛋白,既饲用叶蛋白和食用叶蛋白,打破了国内苜蓿叶蛋白产品只有混合型粗叶蛋白的单一局面,使叶蛋白的蛋白质含量由45%~63%提高到72%,极大地提升了苜蓿深加工产业中的高端产品——叶蛋白的产品档次和利用价值,免去食用叶蛋白中脱色环节,降低成本;同时对残渣、残液中的营养物质进行测定分析,并应用于膳食纤维、饲用等方面。

摘  要:
The secondary processing for destain and removing smell was needed to separate the alfalfa leaf protein (ALP) into white component for edible purpose and green component for forage purpose and the processing procedure was still impractical at present. The white and green components were separated in processing stage in this study and the protein content of extraction was increased to 72%. The utilization value of leaf protein was greatly improved due to the reduction of processing cost and the value-added product. The nutrition components in the residue were analyzed for further utilization.
