Abstract

This study aims to identify the characteristic components of carbon dioxide injury in fresh-cut broccoli and establish a foundation for early warning and precise control of CO2 concentration, thereby enhancing the effectiveness of air conditioning and preservation. Gas chromatography-mass spectrometry was employed to analyze the trend of volatile components produced by broccoli under dynamic controlled atmosphere storage. The results indicated that fresh-cut broccoli sustained injury when stored at 0°C with 4% O2 and 3% or higher CO2 concentration, with the injury phenotype being off-odor. The contents of propionic acid specifically increased under injured conditions, displaying a significantly different trend compared to hypoxic conditions. Thus, propionic acid can be used as a characteristic component of carbon dioxide injury in fresh-cut broccoli.

Key words

鲜切西兰花极易衰老黄化,严重影响其感官质量和商品价值。为减缓鲜切西兰花衰老黄化,延长贮藏期,研究荧光照射(光照)处理(24 μmol/(m2·s)、12 h/d)对鲜切西兰花贮藏期间(7 ℃、5 d)衰老黄化的影响。结果表明:和黑暗对照相比,光照处理能够显著维持鲜切西兰花叶绿素含量,降低黄化指数(P<0.05),同时诱导葡萄糖、蔗糖和果糖累积,与贮藏初期(第0天)相比,3 种糖在贮藏第5天分别增加了106%、73%和70%;进一步用0、40、80、120、160 mmol/L外源葡萄糖溶液对鲜切西兰花进行培养,结果发现在一定浓度范围(0~120 mmol/L)内,随着外源葡萄糖浓度增加,鲜切西兰花内源葡萄糖含量显著上升,黄化指数显著下降(P<0.05),而且黄化指数与外源葡萄糖浓度、内源葡萄糖含量呈极显著负相关(P<0.01),相关系数分别为-0.958和-0.878。因此,光照处理延缓鲜切西兰花黄化可能与其诱导的可溶性糖尤其是葡萄糖累积有关。
