摘要/Abstract

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。

Abstract:

The effect of varying temperature (0, 5, 10 ℃ and ambient temperature) and gas composition (3%, 6% and 10% O2)
during refrigerated storage on the bitterness of grapefruit was studied. Results indicated that grapefruit bitterness varied with storage
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 fraction of oxygen and
the 10% O2 group showed the smallest change.
