可食性涂膜对双孢蘑菇生理和品质的影响

Effect of Edible Coatings on Physiology and Quality of Mushrooms(Agaricus bisporus)

研究了卡拉胶、羧甲基纤维素钠及其复配涂膜对(2±1)℃下贮藏的双孢菇生理和品质的影响。实验结果表明:羧甲基纤维素钠涂膜抑制双孢菇失重率的效果最好;卡拉胶涂膜在抑制呼吸速率、PPO活性、细胞膜通透性的上升和果实硬度、白度的下降方面效果最好,可以将双孢菇的货架期延长至12 d以上。

The effects of carrageenan,carboxymethyl cellulose solution and their complex film on the physiology and quality of mushrooms stored at（2±1） ℃ were studied.The minimum loss of weight was obtained in fruits coated with CMC coating,the minimum value of respiration rate,PPO activity,membrane permeability and the maximum hardness and L＊ value were obtained in mushrooms coated with carrageenan coating.Overall,the preservation effect of carrageenan film is the best,and it can extend the shelf-life of Agaricus bisporus to more than 12 d.
