摘要
为了探索玉米淀粉生产中的工艺水中的蛋白组分的开发利用,研究一种玉米淀粉工艺水蛋白回收工艺,主要包括处理在湿磨法生产玉米淀粉工艺中的麸质浓缩步骤产生的工艺水,并使用膜技术和热处理技术在回收玉米黄粉的同时获得两种新蛋白产品。研究发现,50 ku和100 ku对丰度较高的30 ku蛋白组分的截留浓缩效果较好,其中,该蛋白富含亮氨酸和缬氨酸等支链氨基酸。分离出的耐热耐酸蛋白组分主要为3 ku^14 ku的部分。所得新蛋白产品可作为食用或饲用蛋白原料使用,并且分别具有增肌和用于酸性食品的潜力。
A study was conducted to develop a technique that can recover protein from the process water in starch wet milling system, which mainly include recollecting corn gluten and obtaining two kinds of novel protein from process water produced during the step of major starch/protein separation by membrane filtration incroporating heat treatment. It was found that ultrafiltration membranes with molecular weight cut-off at 50 ku and 100 ku have better effect on the rejection of 30 ku protein fraction , which is in the enrichment of branched chain amino acids such as Leu and Val. In addition , the obtained protein fractions at molecular weight range of 3 ku to 14 ku were found to resist to heat treatment. The novel protein products can be used as food protein ingredient or protein feed with potential application in muscle building and the acid food or beverage , repectively.
