摘要: 鲜虾蛄包装条件分别为:充氮包装、抽真空包装和普通包装。在-25℃下冷冻8h,然后分别在-5、-10、-15、-20、-25℃等温度条件下贮存,并在不同的贮存时间对虾蛄的感官指标评价、K值和TVB-N(挥发性盐基氮)值进行测定。结果表明虾蛄的K值与TVB-N值有较好的相关性。当虾蛄的K值在20%以下,TVB-N值在30mg/100g以下时,其感官指标在C级以上。在-20℃和-25℃条件下贮存的虾蛄不论是感官指标还是化学指标均无明显的区别。真空和充氮包装使K值与TVB-N值增加的速度放缓,可以延长保鲜时间。

Abstract: The effects of different storage temperature(-5 ℃,-10 ℃,-15 ℃,-20 ℃,-25 ℃) and different package methods(uncover package,vacuum package,package full of nitrogen) on squilla were evaluated by sensory method and biochemical properties including total volatile basic nitrogen(TVB-N)and K value.The result showed that the pertinence of K value and the TVB-N is obvious.When the K value below 20 % and the TVB-N below 30mg/100g,the squilla’s sensory index above the C level.Vacuum package and package full of nitrogen can inhibit the growth of bacteria and extend the shelf life.When the squilla stores at-20 ℃ and-25 ℃,the difference of sensory index and the chemistry index is no obvious.
