黄冠梨销地急速降温条件下适宜贮藏温湿度的筛选

摘要

通过测定黄冠梨采后贮藏中硬度、糖度、酸度、呼吸强度、乙烯释放量、果心褐变情况，研究了急速降温下各温湿度条件对黄冠梨果实贮藏期间品质的影响，以筛选出急降条件下最适宜黄冠梨贮藏的温湿度。结果表明，在急降温处理下，-0.7℃-85%RH温湿度组合能够最大程度地抑制黄冠梨果实的呼吸强度，较好地保持果实硬度。此外，还可以有效延缓黄冠梨果实的果心褐变，减少可滴定酸含量的下降，延缓了黄冠梨果实品质的下降。%The soluble solids content, firmness, release rate of ethylene, respiration intensity and the rate of core browning as the indexes of storage quality were investigated. The objective of this study was to investigate the effect of different temperature and humidity on storage quality of Huangguan pears under rapid cooling , and screen the best storage environment. The results showed that,-0.7℃-85%RH treatment significantly decreased the respiratory rate and the core browning rate of Huangguan pears, postponed the respiration peak coming, inhibited the color changing of the peel, and delayed the decreasing rate of soluble solids content and firmness, compared with the other treatments. In a word, the-0.7℃-85%RH was the best store condition for Huangguan pears under rapid cooling.
