一般认为果蔬产后的损耗包括自然耗损和腐烂耗损两部分。自然耗损又包括由于呼吸代谢引起的干物质的消耗和由于蒸发引起水分的散失。在自然损耗部分,由于水分散失而引起的重量损失约占75%～90%。腐烂损耗的变化幅度很大,既与采前的栽培管理及农业技术的合理应用密切相 Generally believed that the loss of fruit and vegetable postpartum, including natural wear and tear loss of two parts. Natural wear and tear also includes the consumption of dry matter due to respiratory metabolism and the loss of moisture due to evaporation. In the natural loss part, due to water loss caused by weight loss accounts for about 75% to 90%. The variation of decay loss is very large, which is closely related to the cultivation management of pre-harvest and the reasonable application of agricultural technology
