鐵皮柿子氣調(diào)貯藏保鮮實驗及研究

鐵皮柿子氣調(diào)貯藏保鮮實驗及研究摘要：本文采用鐵皮柿子作為實驗對象，對其進行了氣調(diào)貯藏保鮮的實驗研究。首先對鐵皮柿子的特點及其貯藏保鮮的現(xiàn)狀進行了分析，然后設(shè)計并建立氣調(diào)貯藏系統(tǒng)，對其進行了一系列的實驗研究，包括不同CO2濃度和貯藏時間對鐵皮柿子效果的影響、不同氣氛組分對鐵皮柿子品質(zhì)的影響等。

結(jié)果表明，采用5%CO2和8%O2的混合氣體進行氣調(diào)貯藏，可有效地延長鐵皮柿子的保鮮期，保持其外觀和品質(zhì)；隨著CO2濃度的增加，鐵皮柿子的保鮮效果逐漸變好，但也會導(dǎo)致一定程度上的質(zhì)量損失；在不同的貯藏時間內(nèi)，鐵皮柿子的品質(zhì)表現(xiàn)出不同的變化趨勢，其中在20天左右的貯藏時間內(nèi)品質(zhì)表現(xiàn)最佳。本研究為鐵皮柿子的保鮮儲存提供了一定的理論和實驗基礎(chǔ)。
