摘要
以南极冰鱼为原料,经预处理后制得外裹糊鱼块,研究其冻藏过程中品质变化及货架期,以菌落总数、挥发性盐基氮(TVB-N)、硫代巴比妥酸(TBA)值、pH值、色泽及感官评价等为评价指标。结果表明:随着冻藏时间的延长,南极冰鱼外裹糊鱼块的菌落总数呈先下降后上升趋势,TVB-N含量、TBA值和pH值均呈上升趋势,色泽亮度值L*、白度值以及感官评分均呈下降趋势,其冻藏货架期为6个月,超过6个月时,其品质严重下降,达到不可食用阶段。
The quality changes and the shelf life of antarctic ice fish fillets coated with batter during frozen storage were studied,total plate count,total volatile basic nitrogen (TVB-N),thiobarbital acid (TBA) value,pH value,color and sensory evaluation were used as evaluation indexes.The results showed that with the extension of storage time,total plate count decreased first and then increased and TVB-N content,TBA value,pH value were all on the rise.In addition,with the extension of storage time,the brightness value L*,whiteness value in the color value and sensory score all showed a decreasing trend.The shelf life of frozen storage is 6 months.When it is more than 6 months,its quality will be seriously reduced and it will be inedible.
