Sulfur-free fresh-keeping processing technology for fruits and vegetables

Abstract

The invention discloses a fruit and vegetable sulfur-free fresh-keeping processing technology which is characterized by comprising the following steps: step 1, fruit and vegetable decontamination: washing picked fruits and vegetables to remove stains on the surfaces, and naturally airing to obtain decontaminated fruits and vegetables; step 2, pesticide removal of fruits and vegetables: soaking the decontaminated fruits and vegetables in alkaline water, taking out the fruits and vegetables, washing the fruits and vegetables with clear water, and naturally airing the fruits and vegetables to obtain pesticide-removed fruits and vegetables; step 3, sterilizing the fruits and the vegetables: soaking the fruits and the vegetables subjected to pesticide removal in a sterilizing solution, taking out the fruits and the vegetables, washing the fruits and the vegetables with clear water, and naturally airing to obtain the sterilized fruits and the vegetables; step 4, coating the fruits and vegetables: selecting proper antibacterial packaging paper to coat the fruits and vegetables according to the shapes and sizes of the fruits and vegetables, so as to obtain the coated fruits and vegetables; and step 5, fruit and vegetable preservation: the coated fruits and vegetables are placed in a preservation box, and the preservation box is placed in a refrigeration house for storage.

Description

technical field [0001] The invention relates to the field of fruit and vegetable processing, in particular to a sulfur-free fresh-keeping process for fruits and vegetables. Background technique [0002] Fruits and vegetables are perishable commodities. In order to store fresh fruits and vegetables well, in addition to the necessary post-harvest commercialization, there must be appropriate storage facilities, so as to reduce the material consumption of fruits and vegetables, delay ripening and Aging process, prolong postharvest life and shelf life; effectively prevent the growth and reproduction of microorganisms, and avoid rot and deterioration of fruits and vegetables caused by dipping. [0003] In the existing fresh-keeping process of fruits and vegetables, the fruits and vegetables are usually kept fresh by means of sulfur fumigation technology, so that the inside of the fruits and vegetables contains residual sulfur components, which makes the fruits and vegetables produ...
