Pressure-reduced ozone-charged fruit and vegetable storage method

Abstract

The invention discloses a pressure-reduced ozone-charged fruit and vegetable storage method. The storage method comprises the following steps: A, manufacturing a closed pressure-proof storeroom body; B, performing heat preservation in the storeroom; C, setting a full-automatic control system; D, storing fresh fruits and vegetables; E, storing the fresh fruits and vegetables under reduced pressure; F, charging the storeroom with ozone; G, humidifying the storehouse. The closed pressure-proof storeroom body is adopted, so that the pressure and the temperature can be rapidly reduced, the oxygen can be rapidly reduced, and the harmful gas components in the storeroom can be quickly removed, therefore the physiological health of the fruits and vegetables is guaranteed to the largest extent, the stored fruits and vegetables do not age, do not yellow, and do not lose weight, the different varieties of fruits and vegetables can be placed in a mixing manner, the storage amount is large, the operation is flexible, and the use is convenient. The method is adopted to build the fruit and vegetable reduced-pressure storeroom, the preservation cost can be reduced by 30%, the method is simple, the cost is low and the effect is remarkable; test proves that the storage method can remarkably prolong the storage period, the storage period of the vegetables can be 60 days or above, and the storage period of the fruits can be 90 days or above.

Description

technical field [0001] The invention belongs to the technical field of fruit and vegetable storage and preservation, and in particular relates to a storage method for fruits and vegetables under reduced pressure and filled with ozone. Background technique [0002] With the improvement of people's living standards, residents' consumption demand for fresh products continues to expand. However, due to the nature of fresh products, in addition to obtaining part of the nutrition from food, people also need to absorb a large amount of vitamins, fruits and vegetables from fruits and vegetables. Nutrients such as minerals and dietary fiber. Fruits and vegetables are the best representative foods, both natural and healthy. Some fruits and vegetables are very seasonal, and the ripening period is very short, especially when the weather is hot, fruits and vegetables are easy to rot and difficult to preserve. method to prolong the preservation of the original results. [0003] In order...

Problems solved by technology

Furthermore, the skin of fruits and vegetables is easily damaged by collision, and its sugar content is also very high, so it is very easy to be infected by mold, especially in the case of collision damage, it is very easy to breed mold, causing the whole box of cherries to rot, which restricts the cultivation of fruits and vegetables. In addition, the porosity of fruit and vegetable skins is also large, and it is easy to lose water during storage, resulting in loss of skin luster and skin wrinkles, which seriously affects the commodity quality of fruits and vegetables
