摘  要:
为了研究溶菌酶和乳酸链球菌素(Nisin)对草莓(Fragaria ananassa Duch.)的低温保鲜效果,使用不同浓度的溶菌酶与Nisin复配液对草莓进行保鲜处理,贮藏于4℃,对贮藏期间草莓的烂果率、失重率、维生素C含量、还原糖含量、总酸含量进行测定。结果表明,0.01%溶菌酶与0.10%Nisin复配保鲜液对草莓保鲜效果最好,贮藏前5 d无烂果。贮藏第五天草莓失重率为8.24%;维生素C含量为109.0 mg/100 g,下降13.6%;还原糖含量为7.21 g/100 g,上升14.3%;总酸含量为6.21 g/kg,下降43.1%。

摘  要:
The effects of lysozyme and nisin on the cold preservation of strawberry was studied through detecting decay incidence, weightlessness incidence, Vitamin C content, reducing sugar content, total acid content in the preserved strawberry treated with different concentrations of lysozyme and nisin blends at 4 ℃, The results showed that 0.01% Lysozyme and0.10% Nisin blends had best preservation effect for strawberry. There was no rotten fruit during first 5 days of preservation.At the fifth day, the strawberry's weightlessness rate was 8.24%. Vitamin C content was 109.0 mg / 100g with decrease of13.6%. The reducing sugar content was 7.21 g / 100g with increase of 14.3%. The total acid content was 6.21 g / kg with decrease of 43.1%.
