铁皮柿子气调贮藏保鲜实验及研究

铁皮柿子气调贮藏保鲜实验及研究摘要：本文采用铁皮柿子作为实验对象，对其进行了气调贮藏保鲜的实验研究。首先对铁皮柿子的特点及其贮藏保鲜的现状进行了分析，然后设计并建立气调贮藏系统，对其进行了一系列的实验研究，包括不同CO2浓度和贮藏时间对铁皮柿子效果的影响、不同气氛组分对铁皮柿子品质的影响等。

结果表明，采用5%CO2和8%O2的混合气体进行气调贮藏，可有效地延长铁皮柿子的保鲜期，保持其外观和品质；随着CO2浓度的增加，铁皮柿子的保鲜效果逐渐变好，但也会导致一定程度上的质量损失；在不同的贮藏时间内，铁皮柿子的品质表现出不同的变化趋势，其中在20天左右的贮藏时间内品质表现最佳。本研究为铁皮柿子的保鲜储存提供了一定的理论和实验基础。
