摘　　要：酶解牛血制取亚铁血红素肽,并于酶解底物及产物中分别添加不同种类亚铁保护剂,考察其对产物亚铁血红素肽的保护效果。结果表明,复合型保护剂的性能明显优于单一型。与空白组相比,酶解底物添加2∶1(抗氧化剂/还原剂质量比)的复合型保护剂可使亚铁含量提高24.5%;酶解产物中添加复合型保护剂后(2∶1),亚铁含量可提高37.7%。Heme-iron enriched polypeptide product was produced from bovine blood enzymolysis.Various kinds of protective agents were added to the enzymolysis substrates and the products to examine they protective effect on the products.Results show that the compound protective agents are superior to a single protective agent.Ferrous iron in enzymolysis substrates and in products are increased by 24.5% and 37.7% respectively after the addition of compound protective agents with mass ratio of antioxidant/reductant = 2∶1.
