| 摘 要： | 以总挥发性盐基氮(TVB-N)和硫代巴比妥酸值(TBA)作为肌肉鲜度的评定指标,研究在冷藏(4℃)和冷冻(-18℃)条件下鲢(Hypophthalmichthys molitrix)背部和腹部肌肉鲜度的变化情况。结果表明,在贮存过程中,鲢背部和腹部肌肉的TVB-N和TBA均符合一级反应动力学模型;随着温度的升高,反应速率加快;在4℃条件下,鲢肌肉一级鲜度的保质期为27～38 h,二级鲜度为51～65 h,到81～88 h腐败变质;在-18℃条件下,鲢肌肉一级鲜度的保质期为11～18 d,二级鲜度为36～43 d,到73～77 d腐败变质;在同一贮存时间,腹部肌肉的TVB-N和TBA均高于背部;并且,鲢肌肉的TVB-N与TBA呈极显著(P<0.01)的正相关关系。

| Abstract: | The changes in freshness of silver carp stored at 4 ℃ and-18 ℃were studied by measuring the total volatile basic nitrogen(TVB-N) and the thiobarbituric acid(TBA).The results indicated that the changes of TVB-N and TBA during storage followed first-order reaction kinetics model,and they increased with the increase of temperature.At 4 ℃,silver carp muscle presented a shelf life of 27～38 h for the first grade freshness,51～65 h for the second grade freshness,and deteriorated at 81～88 h.At-18 ℃,silver carp muscle presented a shelf life of 11～18 d for the first grade freshness,36～43 d for the second grade freshness,and deteriorated at 73～77 d.At the same storage time,the TVB-N and TBA of silver carp ventral muscles were higher than that of dorsal muscle.There was significantly(P<0.01) positive correlation between TVB-N and TBA. |
