摘要: 以新疆哈密瓜为研究对象,对哈密瓜进行采后热水处理,测定贮藏中哈密瓜的过氧化物酶(POD)活性、呼吸强度、细胞膜透性、可溶性固形物、硬度。结果表明:50、55、60℃热水处理能够提高哈密瓜呼吸高峰的到来,提高哈密瓜的可溶性固形物,保持果实较高的硬度,提高果实POD活性。且以55℃和60℃热水处理效果最显著。

Abstract: The Hami melon treated by heated water was studied in this paper. The peroxidase activity , respiration rate , membrane permeability, total soluble solids (TSS) and hardness of Hami melon were assayed. The results showed that the heat treatment at 50 ℃, 55 ℃ or 60 ℃ on Hami melon can enhance the respiration peak, increase the total soluble solids (TSS), keep the higher hardness, and increase the peroxidase activity. The heat treatment at 55 ℃ or 60 ℃ shows significant difference in comparison with control.
