将猪骨经适当处理后,采用酶解法制备了平均分子量1200～2000道尔顿的缩氨酸(肽)[I],该诱品溶性好,无一般混合氨基酸的异味,臭味、高温煮沸无絮状沉淀发生;在192℃条件下基氨基酸组成不被破坏,经分析,它含18种氨基本酸,(8种必需氨基酸均有),以及有人体需要的Fe、Cu、Zn、Ca、Mn、K、Na等金属元素。急性以及亚急性试验证明无毒。继续采用酸解法,制备了平均分子量350～600道尔的缩氨酸[II]。将缩氨酸[I]应用于酸性饮料、面包生产不仅提高了产品的蛋白含量,而且表现出特殊功能性质,还可以使混浊酒类澄清。将缩氨酸[II]应用于雪花膏,对剥脱性皮炎有一定疗效。
After the pig bone was properly treated, the peptide (I) with an average molecular weight of 1200 to 2000 Daltons [I] was prepared by enzymolysis method. The attractant has good solubility, no common odor, odor and high temperature boiling of mixed amino acids No flocculent precipitation occurs; the amino acid composition at 192 ° C is not destroyed, and it contains 18 kinds of amino acids (all 8 essential amino acids), as well as Fe, Cu, Zn, Ca , Mn, K, Na and other metal elements. Acute and subacute tests prove non-toxic. Continue to use acid hydrolysis method, prepared an average molecular weight of 350 ~ 600 Dole of peptide [II]. Peptides [I] are used in sour beverages and bread production not only increases the protein content of the product, but also shows special functional properties and clarifies the turbid liquor. Peptide [II] is used in the cream, has a certain effect on exfoliative dermatitis.
