In the world, become world the biggest fruit to produce a country, but long-term since because take crop seriously, negligence quality, take measure of the increase production before collecting seriously, negligence collects an aftertreatment, store up treatment, the decay after causing fruit greens product to collect is degenerative and serious, loss is great, main show is in these problems the following respects: 1Structure of breed of product of.1 fruit greens is unreasonable although the crop of fruit greens product of our country is tall, but quality is poorer, market price is low, breed structure is unreasonable, early, medium scale of ripe, late-mature breed is undeserved, do not have especially comfortable the high grade breed at treatment, restricted our country fruit to machine the development of course of study apparently.

因此提高果蔬产品的质量，发展贮藏加工业，是我国果蔬产业发展亟待解决的问题。1 目前我国果蔬产业发展中存在的问题自 1993年以来，我国果品产量跃居世界第 1位，成为世界第一大水果生产国，但是长期以来由于重视产量，忽视质量，重视采前增产措施，忽视采后处理、贮藏加工，造成果蔬产品采后腐烂变质严重，损耗极大，这些问题主要表现在以下几个方面：1.1 果蔬产品品种结构不合理我国的果蔬产品产量虽高，但质量较差，市场售价低，品种结构不合理，早熟、中熟、晚熟品种比例不当，非凡是没有适于加工的优质品种，明显制约了我国果品加工业的发展。
