摘　　要：马铃薯蛋白营养价值很高,与其他谷物蛋白相比,它能弥补水稻、小麦等主粮原料蛋白低的缺陷,市场应用潜力巨大。目前我国马铃薯加工主要集中于淀粉生产,但生产过程产生的废水中富含大量蛋白。高效回收废水中的马铃薯蛋白有助于提高我国食品蛋白资源储量,其具有重要的社会和经济价值。本文系统综述了提取马铃薯蛋白各种方法的优缺点及其应用,化学法实际应用广泛,但蛋白质得率低,使用物理法回收所得的马铃薯蛋白具有很好的品质及纯度,但对设备要求较高。而生物法更简洁高效,但处理效果受温度影响极大。目前我国马铃薯蛋白已广泛应用于食品加工、保鲜材料和动物饲料中。并且本文同时结合现有研究和生产工艺流程,设计了利用酸热沉淀法和超滤法从马铃薯淀粉废水中蛋白质回收生产设备流程,以解决蛋白质得率低及超滤法不能连续生产的问题,提高蛋白回收率,降低生成成本。Potato protein has high nutritional value,compared with other cereal proteins,it can make up for the low protein deficiencies of rice,wheat and other staple food raw materials,the market application potential is large.At present,China's potato processing mainly focuses on starch production,but the production process produces a large amount of protein in the wastewater.Efficient recovery of potato protein from wastewater can help increase China's food protein resources reserves,which has important social and economic value.This paper systematically reviews the advantages and disadvantages of various methods of potato protein extraction and their applications.The chemical method is widely used in practice,but the protein yield is low,and the potato protein recovered using the physical method has good quality and purity,but requires high equipment.The biological method is simpler and more efficient,but the treatment effect is greatly affected by temperature.Currently,potato protein is widely used in food processing,preservation materials and animal feed in China.And this paper also combines the existing research and production process,and designs the production equipment process of protein recovery from potato starch wastewater by acid thermal precipitation and ultrafiltration,in order to solve the problem of low protein yield and continuous production by ultrafiltration,improve the protein recovery rate and reduce the generation cost.
