1-MCP可控缓释包装纸对杏果实贮藏品质的影响

Effect of 1-MCP Controlled Release Packaging Paper on Storage Quality of Apricot Fruit

  • 摘要: 本文以1-甲基环丙烯(1-Methylcyclopropene, 1-MCP)为保鲜剂,将其与不同比例的乙基纤维素(Ethyl cellulose ether,EC)和聚丙烯酸(Polyacrylic acid,PAA)混合匀浆后涂布至纸基上制成1-MCP可控缓释包装纸,研究其释放机制,并利用制作的1-MCP可控缓释包装纸处理在2 ℃下贮藏的赛买提杏,研究1-MCP可控缓释包装纸对杏果实贮藏过程中呼吸强度、硬度、可滴定酸、可溶性固形物、果皮颜色、商品率的影响,以期得到一种能有效延长杏果实贮藏期的保鲜纸。结果表明,在95% RH,2 ℃和80%聚丙烯酸的条件下,1-MCP粉末的颗粒塌陷使气体缓慢释放,释放机制参数为0.49,释放速率随着PAA含量的升高而增大。1-MCP可控缓释包装纸能抑制杏果实呼吸强度高峰的到来,延缓硬度、可滴定酸和可溶性固形物含量的降低,并保持果皮颜色。说明1-MCP可控缓释包装纸能有效保持在低温环境下贮藏的杏果实品质,并为1-MCP可控缓释包装纸运用到其它果蔬的贮藏中提供一定的参考。

     

    Abstract: In this paper, 1-methylcyclopropene (1-MCP) controlled release packaging paper was prepared by mixing 1-methylcyclopropene with different proportions of ethyl cellulose ether (EC) and polyacrylic acid (PAA) and then coating it on the paper base. The release mechanism was studied. Saimaiti apricot fruits stored at 2 ℃ were treated with 1-MCP controlled release packaging paper. The effects of 1-MCP controllable slow-release packaging paper on respiratory intensity, hardness, titratable acid, soluble solids, peel color and commodity rate of apricot fruit during storage were studied in order to obtain a kind of fresh-keeping paper which could effectively prolong the storage period of apricot fruit. The results showed that under the conditions of 95% RH, 2 ℃ and 80% polyacrylic acid (PAA), the particle collapse of 1-MCP powder made the gas release slowly, and the release mechanism parameter was 0.49, and the release rate increased with PAA content. Controlled release 1-MCP-coated paper could inhibit the arrival of the peak of respiration intensity of apricot fruit, delay the decrease of hardness, titratable acid and soluble solid content, and maintain the color of peel. The results showed that controlled release 1-MCP-coated paper could effectively maintain the quality of apricot fruits stored in low temperature environment, and would provide some reference for the application of controlled release 1-MCP-coated paper to the storage of other fruits and vegetables.
