摘要:  研究了热处理结合浸钙处理分别对包装和不包装的半红期草莓的贮藏保鲜效果,结果表明:45℃1%CaCl2溶液浸泡草莓20min后,以30μmPE保鲜膜包装贮藏,可以提高草莓果实的钙含量,保持较高的原果胶含量和硬度,抑制花青苷的形成,有效地延缓果实成熟衰老,达到最佳的保鲜效果。

Abstract: The pretreatment of hot-treatment and calcium-dipping was carried on strawberry at half-red stage under packaging and no-packaging storage. The results showed that dipping in 45 ℃,1% CaCl2 solution for 20 min and then packaged with 30μm PE film could increase the flesh calcium contents, hold higher protopectin content and firmness, inhibit formation of anthocyanin, and effectively delay ripening and senescence, thus attain the best preservation effect.
