摘　　要：为了研究生物保鲜剂对菊黄东方鲀品质的影响,以菌落总数、挥发性盐基氮及汁液流失率为指标,探讨在4℃贮藏条件下,不同生物保鲜剂(茶多酚、乳酸链球菌素以及溶菌酶)处理对菊黄东方鲀品质的影响。结果表明,在贮藏10 d时,0.5%浓度茶多酚组的菌落总数为4.71 lg(CFU/g),TVB-N值为12.82 mg/100 g,汁液流失率为6.12%。在贮藏15 d时,0.2%浓度乳酸链球菌菌落总数仅为4.44 lg(CFU/g),TVB-N值为13.16 mg/100 g,汁液流失率为6.91%。在贮藏10 d时,0.3%浓度溶菌酶组的菌落总数为4.68 lg(CFU/g),TVB-N值为13.25 mg/100 g,汁液流失率为4.47%。空白组在贮藏10 d时的菌落总数达到5.52 lg(CFU/g),显著高于其他保鲜剂处理组(P<0.05)。空白组汁液流失率显著低于保鲜剂组。结论:0.5%茶多酚、0.2%乳酸链球菌素及0.3%溶菌酶对菊黄东方鲀的保鲜效果均最佳。Influences of bio-preservatives on quality changes effect of Takifugu flavidus were investigated.Aerobic plate count,total volatile basic nitrogen(TVB-N)and drip loss were used as evaluation indices to investigate the effects of different bio-preservatives treatments(including tea polyphenol,nisin and lysozyme)on the quality characteristics of T.flavidus during 4℃cold storage.The results showed that the aerobic plate count in the 0.5%tea polyphenol group was 4.71 lg(CFU/g),the TVB-N value was 12.82 mg/100 g,and the drip loss was 6.12%in the 10 days of storage.In the 15 days of storage,the aerobic plate count of 0.2%nisin group was only 4.44 lg(CFU/g),its TVB-N value was 13.16 mg/100 g and the drip loss was 6.91%.During the aerobic plate count in the 10 days of storage,TVB-N value and the drip loss in the 0.3%lysozyme group was 4.68 lg(CFU/g),13.25 mg/100 g,and 4.47%,respectively.The aerobic plate count in the blank group reached 5.52 lg(CFU/g)in 10 days of storage,which was significantly higher than that of other preservative groups(P<0.05).Furthermore,the drip loss of the blank group was significantly lower than that of preservative groups.So the conclusion was that 0.5%tea polyphenols,0.2%nisin and 0.3%lysozyme had the best preservative effect on T.flavidus,respectively.
