Cheese whey protein membrane recycling technology and membrane fouling problem

随着乳清蛋白较高的生理活性和理化特性不断被发现,并且广泛的应用于食品生产中,乳清蛋白的高效回收技术也越来越受到全球食品领域的关注。膜技术的出现使乳清蛋白的高效快速回收成为可能,但膜污染问题所带来的相对较高的回收成本制约着膜回收乳清蛋白的广泛推广。然而在乳清蛋白膜回收过程中,影响膜污染的因素十分复杂。该文从膜材料和膜回收工艺在乳清蛋白回收中的应用进行综述,此外对导致乳清蛋白回收过程中的膜污染机制进行了综合分析,为今后乳清蛋白膜回收技术的创新提供理论基础。

With higher physiological activities and physicochemical properties of whey proteins have been found and widely used in food production, the efficiency of whey protein recovery technology at tracted more and more attention in the field of food globally. The emergence of membrane technology made it possible forefficient rapid recovery of whey protein. However, the membrane fouling problems bringing relatively high cost for recycling restricted wide application of the membrane recovery of whey protein. Furthermore, in the process of whey protein membrane recycling, the factors influencing membrane fouling were very complex. The application of the membrane material and membrane recovery of whey protein was reviewed in this article. The membrane fouling mechanism for whey protein recycling was also analyzed. This review wouldalso provide theoretical basis for the innovation of whey protein membrane recycling technology in future.
