醇法大豆浓缩蛋白萃取过程中溶剂渗透速率的影响因素
|
摘要
研究了醇法大豆浓缩蛋白萃取过程中溶剂渗透速率的影响因素,结果表明,原料粉末度过高、萃取温度过高降低渗透速率;使用溶剂对原料进行预变性、预溶胀可以提高渗透速率。因此,在工业化生产过程中采用原料进行筛分粕末、常温萃取、预浸处理是提高萃取过程中渗透速率的有效手段。
The influential factors of solvent permeation rate in the extraction process of alcohol leached soy protein concentrate(ALSPC) were studied. The research shows that too much powder in the raw material, the extraction temperature was too high reduced the permeation rate, and pre-denaturation and pre-swelling of the raw materials can increase the permeation rate. Therefore, in the industrial production process, screening powder from raw materials, ambient temperature, pre-leaching treatment is effective means to improve the permeation rate.
