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.
