茶多酚-川陈皮素-羧甲基纤维素钠复合涂膜剂对刺嫩芽的保鲜效果

Fresh-keeping Effect of Tea Polyphenolsand Nobiletin and Sodium Carboxymethyl Cellulose Composite Coating Agent on Aralia elata(Miq.)Seem.

  • 摘要: 利用茶多酚、川陈皮素和羧甲基纤维素钠(Sodium carboxymethyl cellulose,CMC-Na)进行复合涂膜的制备,以刺嫩芽为保鲜对象,以感官评价、失重率、硬度、叶绿素、VC含量、多酚氧化酶活性和丙二醛含量为指标,多方面评定复合涂膜对刺嫩芽的保鲜效果,并分析了可能的保鲜机理。结果表明:复合涂膜组对刺嫩芽的保鲜效果明显优于对照组,同时也明显优于茶多酚涂膜组和川陈皮素涂膜组。复合涂膜剂可有效地抑制刺嫩芽菜体褐变,维持多酚氧化酶和丙二醛处于较低水平,保持菜体组织形态,保证较高的感官品质,延缓其VC含量和水分的损失。贮藏12 d时,与对照组相比,复合涂膜处理的刺嫩芽VC含量提高1.4倍,失重率减少31%,综合各保鲜指标分析,复合涂膜可以延长刺嫩芽4~5 d的贮藏时间。

     

    Abstract: The preparation of composite coating film was carried out by using tea polyphenol,nobiletin and sodium carboxymethyl cellulose(CMC-Na),and the Aralia elata(Miq.)Seem. was used as preservation objects for sensory evaluation. The sensory evaluation,weight loss rate,hardness,chlorophyll,VC content,tpolyphenol oxidase activity and malondialdehyde content were used as indicators. The preservation effect of the composite coating on Aralia elata(Miq.)Seem. was evaluated in these aspects,and the possible preservation mechanism was analyzed. The results showed that the fresh-keeping effect of the composite coating group on the Aralia elata(Miq.)Seem. was significantly better than that of the blank control group,and it was also superior to the tea polyphenol coating group and the nobiletin coating group.The composite coating agent could effectively inhibit the browning of the Aralia elata(Miq.)Seem.,maintain the polyphenol oxidase and malondialdehyde at a low level,maintain vegetable tissue morphology,ensure high sensory quality,delay the loss of VC content and moisture.When stored for 12 days,compared with the control group,the VC content of the composite coating film increased by 1.4 times,the weight loss rate decreased by 31%,based on the analysis of various fresh-keeping indexes,the composite coating film could prolong the Aralia elata(Miq.)Seem. storage time for 4~5 d.
