Abstract

The invention discloses a fresh-keeping storage method for green vegetables. The fresh-keeping storage method includes the following steps that a, the harvested green vegetables are sorted, the greenvegetables which have been corrupted or damaged are removed, and roots of the green vegetables are cut off through a cutter subjected to high-temperature disinfection; b, the green vegetables processed in the step a are placed in saline water to be soaked, and the green vegetables are flushed with clear water to be clean after being soaked; c, the green vegetables which are flushed to be clean arefished out after being soaked in water containing ozone; d, the green vegetables processed in the step c are bundled up through rubber hands, wherein the bundling positions are petioles, close to theroots, of the green vegetables; e, the bundled green vegetables are hung in a carriage of a refrigerator truck at intervals, the petioles face upwards and leaf tails face downwards according to the hanging direction, and temperature in the carriage is controlled to range from 2 DEG C to 8 DEG C; f, water mist is sprayed to the green vegetables in the carriage at intervals; and g, carbon dioxide gas is input in the carriage, and the oxygen content in the carriage is decreased. The fresh-keeping storage method has the technical effect of prolonging the fresh-keeping time of the green vegetables.

Description

Technical field [0001] The invention relates to the technical field of vegetable preservation, in particular to a method for preservation and storage of green vegetables. Background technique [0002] Pak choi is a general term for leafy vegetables with fresh leaves and petioles as products. It contains minerals, vitamins, fiber and other nutrients, and has high nutritional value. Vegetables have a very high water content. After harvest, they are easily infected by harmful microorganisms such as bacteria and molds, resulting in decay and deterioration, which is not conducive to storage and transportation. After harvest, the vegetables lose their water source, resulting in reduced moisture in the tissues and cell turgor. , Which makes the vegetables lose their fresh state, such as wilting, shrinking, and loss of luster. Therefore, the research and development and application of scientific, standardized and perfect fresh-keeping methods in the logistics process of vegetables are p...
