为研究短波紫外线(short-wave ultraviolet,UV-C)处理对青椒色泽和生理品质的影响,本实验以不同剂量UV-C处理青椒,得到最佳处理剂量,然后采用最佳剂量的UV-C(0.25 kJ/m^2)处理青椒,分别将其进行常温和冷藏方式贮藏,测定青椒贮藏过程中的感官品质和总叶绿素、类胡萝卜素、类黄酮、总酚含量,同时测定过氧化物酶(peroxidase,POD)、过氧化氢酶(catalase,CAT)、抗坏血酸过氧化物酶(ascorbate peroxidase,APX)、多酚氧化酶(polyphenol oxidase,PPO)及八氢番茄红素合酶(phytoene synthase,PSY)、番茄红素β-环化酶(lycopene-β-cyclase,LCYB)活力的变化。结果表明:UV-C处理可明显提升青椒的外观品质,减缓叶绿素降解,并降低PSY和常温贮藏下LCYB活力,进而影响青椒中类胡萝卜素的合成,抑制类胡萝卜素和类黄酮含量的升高,从而延缓青椒转红。此外,与对照相比,UV-C处理还能降低青椒中的PPO活力,有效延缓果实褐变,并诱导酚类物质的合成,提高POD、CAT和APX活力,提高抗氧化能力。结论:UV-C处理可以延缓青椒转红,维持青椒在贮藏期间的生理品质,有效延长青椒的货架期,结果可为青椒的采后贮藏保鲜提供理论依据。

通过对糙皮侧耳（Pleurotusostreatus）子实体在0、2．5和5℃恒温贮藏和0℃温度波动贮藏对比试验，通过对失重率、呼吸强度、色泽（L＊值和b＊值）、细胞膜相对电导率、可溶性固形物的测定及感官评定研究了温度对糙皮侧耳子实体品质的影响。结果表明，贮藏温度和温度波动会对糙皮侧耳子实体品质造成明显的影响，5℃恒温贮藏的糙皮侧耳品质最差，0℃是最适宜糙皮侧耳子实体贮藏的温度，但贮藏过程中的温度波动显著影响糙皮侧耳子实体品质，会使子实体的失重率、呼吸强度、b＊值和细胞膜相对电导率升高，可溶性固形物含量和感官评定值下降。
