摘要
为减缓鲜切西兰花贮藏期间品质下降,延长贮藏期,运用分光光度法研究连续光照处理(2000 lx)对鲜切西兰花低温贮藏期间品质变化的影响。结果表明,和黑暗对照相比,光照处理显著减缓鲜切西兰花贮藏期间叶绿素降解和黄化发生率,维持类胡萝卜素、可溶性固形物和抗坏血酸含量,从而使其保持较高的抗氧化力。然而,光照处理显著促进鲜切西兰花鲜质量损失。
In this study, the effect of continuous light illumination at 2000 lx on the quality of fresh-cut broccoli during 7 days of cold storage was investigated by spectrophotometry. The results indicated that light illumination significantly alleviated chlorophyll degradation and yellowing occurrence during storage, and meanwhile could maintain carotenoids, total soluble solid and vitamin C contents as well as antioxidant capacity of fresh-cut broccoli during storage. However, light illumination also induced more weight loss of fresh-cut broccoli during the whole storage compared with dark storage.
