冰温贮藏对西兰花保鲜的影响

Effect of ice-temperature storage on the freshness retaining of broccolis

  • 摘要: 研究冰温贮藏对西兰花保鲜效果的影响。将西兰花分为两组,一组存于冰温库中(-0.7~-0.4)℃,另一组存于普通冷库中(-1~1)℃。每14d取样测定其理化指标及营养成分。实验结果表明:冰温贮藏对于延缓西兰花可溶性固形物含量、可溶性糖浓度和VC含量的下降具有明显的效果,可显著抑制西兰花贮藏期间乙烯生成率,延迟乙烯高峰的出现,但对呼吸的抑制效果不大;冰温贮藏提高了西兰花POD、SOD和CAT等的活性,降低了PPO的活性,延缓了西兰花的衰老。这说明西兰花适于冰温贮藏,且冰温贮藏的效果优于普通冷藏的效果。 

     

    Abstract: In order to investigate the effect of ice-temperature storage on the results of freshness retaining of broccolis, the broccolis were stored under two different storage temperatures.One was-0.7~-0.4℃, and the other was-1~1℃.The physicochemical indexes and nutrition components were measured for 14 days.The research results showed that the soluble solids content, soluble sugar and vitamine C of the broccolis by ice-temperature storage decreased less than that of ordinary storage.Ice-temperature storage could significantly inhibit the ethylene generation rate of the broccolis, but the inhibition effect on respiration of the broccolis was not obvious.The activities of peroxidase (POD) , superoxide dismutase (SOD) and catalase (CAT) were promoted and the activity of polyphenol oxidas (PPO) was reduced, in turn, the ripening of broccolis was delayed.Therefore, the storage effect of broccolis by ice-temperature storage is superior to that by ordinary storage.
