二氧化碳是果蔬呼吸代谢的最终产物,在适宜的CO_2浓度下,不少水果可保持鲜嫩外观和良好风味及品质,商品腐烂损耗下降,因而在水果的贮藏和运输中得到广泛的应用,是气调贮藏技术取得良好效果的重要原因之一。CO_2的应用方法基本上可分二大类:1.以高浓度CO_2作水果采后短期处理;2.在适宜的CO_2浓度下,对水果进行长期贮藏。但是,无论哪一种方法,在具体应用时,都存在着临界浓度或临界处理时间问题。一旦超过界限,就会导致水果伤害,使商品受到损失。 Carbon dioxide is the end product of the respiratory metabolism of fruits and vegetables. Under suitable CO 2 concentration, many fruits can maintain fresh appearance and good flavor and quality, and the decay loss of the commodity decreases. Therefore, it is widely used in the storage and transportation of fruits, Storage technology to achieve good results one of the important reasons. The application method of CO_2 can basically be divided into two categories: 1. Short-term treatment with high concentration of CO_2 for fruit picking; 2. Long-term storage of fruits under suitable CO_2 concentration. However, no matter which method is used, there is a problem of critical concentration or critical processing time in specific applications. Once beyond the limit, it will lead to fruit damage, so that the loss of goods.
