摘　　要：研究气体结合高静压(high hydrostatic pressure,HHP)处理对干锅藕片的货架期及贮藏品质的影响。测定充气包装后经高静压处理的干锅藕片在贮藏过程中微生物菌落总数、质构、色差、油脂过氧化值的变化及感官评价。结果表明:充CO_2结合高静压(CO_2-HHP)处理的干锅藕片贮藏期较充N_2、充CO_2、真空包装结合高静压(vacuum-HHP)处理、充N_2结合高静压(N_2-HHP)处理长,且第一循环硬度保持在14 000 g左右,b*值变化在2以内CO_2-HHP处理的干锅藕片在贮藏期内感官评价始终较好。这为低酸性食品的保藏提供了新的思路与方法。Dry pot lotus root slices is a popular Chinese dish with rich nutrients and good taste.This study was done to analysis the effects of gas packaging combined with high hydrostatic pressure(HHP)on the shelf life and storage quality of dry pot lotus root slices.For this purpose,changes in total colony count,texture,color difference,lipid peroxidation and sensory evaluation of dry pot lotus root slices during storage after sequential gas packaging combined with HHP treatment were measured.The results showed that compared with N2packaging,CO2packaging,vacuum packaging combined with HHP,and N2packaging combined with HHP,the shelf life of dry pot lotus root slices treated by CO2packaging combined with HHP was longer,the hardness during the first cycle was maintained at about14000g,and the decrease in b*value was less than2during storage.Sensory evaluation of the product subjected to CO2packaging combined with HHP was also good.Thus,the results provide new ideas and methods for the preservation of low acid foods.
