对鸭血酶水解得到的鸭血水解物进行主要营养成分、氨基酸组成、肽相对分子质量分布的研究.结果表明,干燥的鸭血水解物蛋白质含量达40.2%,铁和锌含量分别为484mg/kg和22.8mg/kg,除了未检测色氨酸以外,其它氨基酸组成平衡,必需氨基酸含量占氨基酸总量的42.3%,特别是富含普通谷物中极易缺乏的赖氨酸、苏氨酸和缬氨酸等.采用高效凝胶过滤色谱法(HPSEC)研究了鸭血水解物肽的相对分子质量分布范围,结果表明,相对分子质量基本上在10000 D以下,在标样分子量范围内的8种肽类物质相对分子质量分别为10702、7788、6059、4113、3421、2417、1495、1065 D,相对分子质量小于451 D的小肽含量也有24.72%,这也进一步证实了鸭血蛋白的酶水解.起到了有效降解相对分子质量较大且不易为人体吸收利用的血红蛋白的作用.

This study focus on primary nutrient components,amino acid components and relative molecular weight of duck blood hydrolysate peptides gained by protease hydrolysis.The results show that dry duck blood hydrolysates are rich in protein,iron and zinc.The content is 40.2%,484 mg/kg and 22.8 mg/kg,respectively,amino acid components is balanceable except not detecting tryptophan,and necessary amino acid content is 42.3%,especially lysine,threonine and valine which lacking in corn,and so on.The relative molecular weight distribution of duck blood hydrolysates peptides was determined using HPSEC.The results show that duck blood hydrolysates have lower 10000 D average molecular weight.The molecular weight of 8 peptides that in the scope of standard sample are 10702,7788,6059,4113,3421,2417,1495 and 1065 D,small peptides(≤451 D)content is 24.72%,which explains that protease hydrolysis plays an effective role in the degradation of hemoglobin that is larger molecular weight and not easily absorbed and used by the body.
