Abstract

Vacuum and modified atmosphere packaging are widely used for preserving food items including fish. In this context, the quality and shelf life of air- (control), vacuum- and nitrogen-packed dried barb fish (Puntius spp.) stored at ambient temperature were evaluated through biochemical and microbial analyses for 90 days. In most of the storage days, significantly lower values of moisture, total volatile base-nitrogen (TVB-N) and peroxide value (PV) were observed in the vacuum pack sample compared to control. However, the TVB-N, PV, total coliforms and faecal coliforms counts were within the acceptable limit in all groups. The total plate count (TPC) increased gradually with time from an initial value of 4.29 log CFUg–1. However, compared to control, significantly lower TPC were found on and after the 30th day of storage in vacuum and nitrogen pack samples. Considering the TPC value of 5 log CFUg–1, the shelf life was determined at approximately 15 days for control, 35 days for nitrogen pack and 45 days for vacuum pack samples. Therefore, the vacuum pack is considered the best packaging, which may be utilised by the processors to produce and retail the dried products with prolonged shelf life.
真空包装和氮包装干倒刺鱼的质量和保质期
真空和气调包装广泛用于保存包括鱼类在内的食品。在此背景下,通过生化和微生物分析,对空气(对照)、真空和氮气包装的干倒刺鱼(Puntius spp.)在常温下储存90天的质量和保质期进行了评价。在大部分的贮藏时间内,真空包装样品的水分、总挥发性碱氮(TVB-N)和过氧化值(PV)均显著低于对照。但各组TVB-N、PV、总大肠菌群和粪便大肠菌群数量均在可接受范围内。总平板计数(TPC)从初始值4.29 log CFUg-1逐渐增加。然而,与对照相比,真空和氮气包装样品在第30天及其后的TPC显著降低。考虑到5 log CFUg-1的TPC值,确定对照样品的保质期约为15天,氮气包装样品为35天,真空包装样品为45天。因此,真空包装被认为是最好的包装,加工商可以利用它来生产和零售具有延长保质期的干燥产品。
