摘　　要：水解乳清蛋白由氨基酸、寡肽和多肽组成,属于预消化蛋白。水解后的乳清蛋白降低了乳蛋白的抗原性,水解程度越高,抗原性越低,适度水解乳清蛋白能够诱导婴儿对乳蛋白产生耐受性。使用水解乳清蛋白制备的短肽型肠内营养制剂比整蛋白型产品易消化吸收;比氨基酸型产品渗透压低、耐受性高,不易引发腹泻。含水解乳清蛋白、不含膳食纤维的无渣饮食用于肠道准备能缓解患者的不适,降低胰岛素抵抗,更有利于患者恢复。运动营养中使用水解乳清蛋白,不仅消化速率快,富含亮氨酸,还含有抗氧化肽,能促进运动后的肌肉恢复。水解乳清蛋白含多种生物活性肽,是最有潜力的保健食品原料之一。水解乳清蛋白因其低致敏性、易消化、无渣、富含生物活性肽的特点,广泛应用于特殊医学用途配方食品、运动食品和保健食品等。Whey protein hydrolysate is composed of amino acids,oligopeptides and peptides,which belongs to pre digested protein.Hydrolyzed whey protein reduces the antigenicity of milk protein.The higher the degree of hydrolysis,the lower the antigenicity.However,partially hydrolysed whey protein can induce the milk protein tolerance of allergy infant.The short peptide enteral nutrition(EN)prepared by whey protein hydrolysate is easier to digest and absorb than the whole protein product,and it has lower osmotic pressure,higher tolerance than amino acid products.The short peptide EN is not easy to cause diarrhea.A residue free diet containing whey protein hydrolysate and no dietary fiber for intestinal preparation can alleviate the discomfort of patients,reduce insulin resistance and be more conducive to the recovery of patients.The use of whey protein hydrolysate in sports nutrition not only has fast digestion rate and rich in leucine,but also contains antioxidant peptides,which can promote muscle recovery after exercise.The whey protein hydrolysate contains a variety of bioactive peptides and is one of the most potential raw materials for health food.Whey protein hydrolysate is widely used in special foods such as formula food for special medical purposes,sports food and health food because of its low sensitization,easy digestion,no residue and rich in bioactive peptides.
