Effects of storage conditions on physiological and biochemical quality of Wannuo 2000 during processing period
The quality of fresh waxy corn will decline due to respiration and water loss after harvest,so it needs to be preserved in time.In this paper,the effects of storage temperature and preservative 1-methylcyclopropene(1-MCP)on respiratory rate of fresh waxy corn(Wannuo 2000),as well as the changes in water content,soluble solids content and weight loss rate of such corn under these conditions were systematically evaluated.The results showed that the respiration rate of Wannuo 2000 was significantly inhibited by the treatment of 4℃ combined with 1-MCP during storage for 6 hours,the weight loss rate and the loss of soluble protein were reduced.Meanwhile,the water retention rate was 97.61％and the soluble solid retention rate was 89.13％,so that the aging process of the fresh waxy corn was delayed,and the quality of fresh waxy corn in the processing period after harvesting was improved.The result can provide theoretical support for establishing the storage conditions of the fresh waxy corn in the processing period after harvesting.
