摘　　要：为探究气调包装对糙米储藏期间品质的影响,分别采用空气、真空、100%N2、90%N2+10%O 2和70%N2+30%O2包装糙米,研究在长期储藏过程中(6个月)糙米的品质变化情况。研究发现,在所有包装方式中,90%N2+10%O2包装展现出最好的储藏效果。与空气对照相比,L*值增加22%,b*值降低15%,细菌总数和霉菌总数分别降低50%和24%,脂肪酸值和丙二醛含量分别减少11%和47%,保持淀粉粒微观结构,硬度减小12%,而黏着性和回复性分别提高17%和32%。储藏实验结果证实90%N2+10%O2气调包装能够作为一种有效的糙米包装方式。To study the effect of modified atmosphere packaging on quality of brown rice during storage at 37℃.The modified atmosphere environment was as follows:vacuum,100%N2,90%N2+10%O2 and 70%N2+30%O2.The effect of different atmosphere packaging on the quality of brown rice during prolong storage(6 months)was studied.The results show that 90%N2+10%O2 packaging exhibits the best preservative effect.Compared with air packaging,90%N2+10%O2 packaging increased L*value by 22%,reduced b* value by 15%.Total bacterial count and total mould count were inhibited at the temperatures 50% and 24%,respectively.Fatty acid value and malondialdehyde content were reduced by 11%and 47%,respectively.The starch granular microstructure was maintained best.The hardness was reduced by 12%,while cohesiveness and resilience increased by 17% and 32%,respectively.These results of storage test indicated that 90%N2+10%O2 packaging might be a kind of effective packaging for brown rice.
