摘要
研究冷藏过程中温度(0、5、10℃、室温)和气体体积分数(3%、6%、10%O2)的改变对胡柚苦味变化的影响。结果表明:温度对苦味变化影响显著,整个贮藏期中,各温度条件下苦味物质含量均出现了较大地波动,但各组变化趋势基本一致,具体表现为贮藏0-30d期间有一定的增加,30~105d期间出现下降趋势并逐渐趋于稳定,而10℃条件下苦味物质含量一直处于各组最低水平。气体体积分数改变时,对比对照组,3组气调处理的胡柚果实中苦味物质均出现不同程度的增加或减少,但并不呈现特定的规律性;贮藏30~105d,随着O2体积分数的增加,胡柚苦味物含量波动幅度减小,且以10%O2组含量最低。
The effect of varying temperature (0, 5, 10 ℃ and ambient temperature) and gas composition (3%, 6% and 10% 02) during refrigerated storage on the bitterness of grapefi'uit was studied. Results indicated that grapefruit bittemess varied with stor- age temperature and the content of bitter compounds dramatically fluctuated in a substantially consistent manner throughout the storage period under varying temperatures, which was manifested by an increasing trend during the first 30 days before decreasing and then remaining stable during 30-105 days. The minimum amount of bitter compounds was detected in grapefruit stored at 10 ℃. Compared with the control group, three MAP groups contained more or less bitter compounds, showing irregular changes. During 30-105 days, smaller fluctuations were found for the amount of bitter compounds with increasing volume fi'action of oxygen and the 10% 02 group showed the smallest change.
