【摘要】：本文針對風(fēng)冷冰箱中冷凍豬肉品質(zhì)下降的問題,提出了一個操作簡單方便、效果良好的解決措施:抽氣貼體包裝(包裝袋內(nèi)留有5%~8%空氣,包裝袋與肉貼合)。通過實(shí)驗(yàn)測定了不包裝、密封包裝、抽氣貼體包裝的冷凍豬肉干耗率、解凍汁液流失率、色差、質(zhì)構(gòu)特性、剪切力、微觀結(jié)構(gòu)等指標(biāo),研究了不同包裝方式對冷凍豬肉品質(zhì)的影響。研究發(fā)現(xiàn):不包裝的干耗率、L*值、b*值顯著大于密封包裝和抽氣貼體包裝,解凍汁液流失率、a*值、質(zhì)構(gòu)特性、剪切力顯著低于密封包裝和抽氣貼體包裝,微觀結(jié)構(gòu)的完整性受到破壞的程度嚴(yán)重,肌纖維斷裂,呈無序性排列;抽氣貼體包裝的干耗率在60 d后顯著小于密封包裝,解凍汁液流失率、色差、質(zhì)構(gòu)特性、剪切力均優(yōu)于密封包裝,微觀結(jié)構(gòu)的完整性更好。結(jié)果表明密封包裝和抽氣貼體包裝可以有效地維持凍肉品質(zhì),抽氣貼體包裝的效果優(yōu)于密封包裝,更具有可行性。
[Abstract]:In order to solve the problem of the deterioration of frozen pork quality in air-cooled refrigerator, this paper puts forward a simple and convenient way to solve the problem. The solution is that the packing of air is fitted to the body (5% air is left in the bag, and the bag fits with the meat). The dry consumption rate of frozen pork, the loss rate of thawing juice, color difference, texture characteristics, shear force, microstructure and so on were measured by experiments. The effects of different packaging methods on the quality of frozen pork were studied. The results showed that the dry consumption rate, L * value, b * value of unpacked package were significantly higher than those of sealed package and air fitted package, the loss rate of thawing juice, a * value, texture characteristic, shear force of unpacked package were significantly lower than those of sealed package and air fitted packing. The integrity of the microstructure was damaged seriously, the muscle fibers were broken and arranged disorderly. The dry consumption rate of air-fitted packing was significantly lower than that of sealed package after 60 days. The loss rate of thawing juice, color difference, texture characteristic and shear force were better than that of sealed package, and the integrity of microstructure was better than that of sealed package. The results showed that the quality of frozen meat could be maintained effectively by sealed packaging and air-fitted packing, and the effect of air-fitted packing was better than that of sealed packaging, and it was more feasible.
