低变性大豆蛋白生产工艺

Production Technology of Low Denatured Soybean Protein

该工艺利用液化烃（丙烷、丁烷混合物）作浸出溶剂，在提取大豆油后，低温（３５℃）脱除豆粕中的溶剂，可获得水溶性蛋白保持率９０％以上的低变性豆粕。该产品可制备各种蛋白食品如分离蛋白粉、浓缩蛋白粉等。

Liquefied hydrocarbon was used as solvent to extract soybean oil.After extracting,the solvent in the meal was desolventized at low temperature (below 35℃) to obtained low denatured protein materials in which soluble protein content was over 90%.The protein products can be utilized to produce various protein foods,such as isolated protein meal,concentrated protein meal,etc.
