Abstract

The invention discloses a method for preserving fruit. The method comprises the following steps: pre-treating the fruits, first refrigerating, second refrigerating, third refrigerating, aerating, sterilizing and completing. By using the method for preserving fruit, respiration and metabolism of the fruit can be effectively inhibited, so that ripening and aging of the fruit are postponed and quality of the fruit is maintained. According to the method, the fruit is pre-treated by gradual cooling, so that the fruit has a good adapting process to effectively avoid chilling injury caused by excessively low temperature of the refrigerator when the fruit enters the refrigerator for the first time; post-treatment of aerating is also utilized to suppress growth and metabolism speeds of the fruit, so that the fruit is effectively preserved. Innocent treatments are utilized in the whole preservation process of the method for preserving fruit, so that the method overcomes problems of multiple methods for preserving fruits, such as single preservation type, complex preservation method and impossible mixed preservation.

Description
