Abstract

The invention belongs to productive technology for preserving and processing fruits and vegetables, mainly comprising the processes of grading selection, cleaning, arranging and splitting, preserving, dewatering and sterilizing, packing and refrigerating and the like. The technology is mainly characterized in that after two times of sterilizing by ozone and ultraviolet rays in sequence, the fruits and vegetables are soaked by an natural edible antistaling agent to form a film so as to carry out atmosphere packaging by mixed gas, thereby maximally maintaining nutritional quality of the fruits and vegetables, improving edible safety of the fruits and vegetables and prolonging sale and preservation period.

Description

Technical field: [0001] The invention belongs to the field of fruit and vegetable processing and preservation, in particular to a production process for fruit and vegetable preservation. It is suitable for fresh-keeping processing of fruits and vegetables before sale. Background technique: [0002] With the progress of the "Vegetable Basket" project, my country's fruit and vegetable production has developed rapidly, accounting for 30% of the world's total fruit and vegetable production, ranking first in the world, and has become my country's second most important agricultural product after grain. However, since fruits and vegetables are agricultural products with strong regional and seasonal characteristics and are perishable, the loss rate in each link from fruit and vegetable harvesting, storage and transportation, processing to sales and circulation is as high as 30%. With the improvement of China's economic level and the acceleration of the pace of life in modern societ...
