摘要
为延长冷却猪肉的保质期,选择气调包装合适的气体组分,通过将不同气体比例气调包装放置在7℃条件下贮藏,运用响应面软件研究气调包装冷却猪肉中细菌总数、假单胞菌、乳酸菌等微生物的生长概率.研究表明,O2对假单胞菌和细菌的作用相当显著,CO2对乳酸菌的作用比较显著.通过Design Expert软件对试验数据进行回归分析,预测最佳比例,得出假单胞菌优化气体比例为CO2 31%+O2 49%+N2 20%,乳酸菌优化气体比例为CO2 37%+O2 35%+N2 28%,细菌总数优化气体比例为CO2 36%+O244%+N2 20%.
Abstract
In order to extend the shelf life of cooling of pork,and provide the basis for its gas packaging components,this experiment using response surface software build different gas proportion,through the proportion of different gases and gas packaging to place it at 7 ℃ under the condition of storage,modified atmosphere research pseudomonas,lactic acid bacteria in cooling pork growth probability,total number of bacteria and other microorganisms.Studies have shown that oxygen of pseudomonas bacteria is very significant,carbon dioxide is significant for the role of lactic acid bacteria.Through the Design Expert software regression analysis of experimental data,forecast the best proportion.Pseudomonas optimized gas proportion isCO2 31%+O2 49%+N2 20%,optimized gas ratio of lactic acid bacteria:CO2 37%+O2 35%+N2 28%,optimized gas ratio of total bacteria isCO2 36%+O2 44%+N220%.
