Technical problem to be solved

Aiming at the defects of the prior art, the invention provides a method for preserving fruits and vegetables and application thereof, and solves the problem that fruits and vegetables are easy to rot.

(II) technical scheme

In order to achieve the purpose, the invention provides the following technical scheme: a method for keeping fruits and vegetables fresh comprises the steps of putting fresh fruits and vegetables into a vacuum bag, pumping air out of the vacuum bag, injecting low-concentration ozone and negative oxygen ions into the vacuum bag, sealing the vacuum bag, selecting a cuboid-shaped heat preservation box, putting ice bags into the heat preservation box, and putting a plurality of fruits and vegetables into the heat preservation box.

Preferably, the vacuum bags are cylindrical structures, and one fruit and vegetable is placed in one vacuum bag.

Preferably, the air content evacuated from the vacuum bag is 90%.

Preferably, the number of the ice bags is multiple and is divided into five groups, one group of the ice bags is placed on the lower surface inside the heat preservation box, and the remaining four groups of the ice bags are placed on the four side walls of the heat preservation box.

Preferably, the humidity in the incubator is 95%.

The invention also provides an application of fruit and vegetable fresh-keeping, wherein the fruit and vegetable can be apples, honey peaches, oranges, lettuce and the like, picked honey peaches are put into a vacuum bag, air is pumped out from the vacuum bag, low-concentration ozone and negative oxygen ions are injected into the vacuum bag, the vacuum bag is sealed, a cuboid-shaped heat preservation box is selected, ice bags are evenly put into the interior and the inner side wall of the heat preservation box, and then the honey peaches are sequentially put into the heat preservation box from bottom to top.

(III) advantageous effects

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1-3, the present invention provides a technical solution: a method for preserving fruits and vegetables includes putting fresh fruits and vegetables in a vacuum bag, pumping air out of the vacuum bag, injecting low-concentration ozone and negative oxygen ions into the vacuum bag, sealing the vacuum bag, selecting a cuboid-shaped heat preservation box, putting ice bags in the heat preservation box, and putting a plurality of fruits and vegetables in the heat preservation box.

Furthermore, the vacuum bag is cylindrical structure, puts into a fruit vegetables in a vacuum bag, and cylindrical vacuum bag packs into the fruit vegetables and pours into ozone and negative oxygen ion back, and the vacuum bag expands for the vacuum bag stands, like this, puts the back at the vacuum bag from bottom to top, and the vacuum bag can play keeps apart, shock attenuation, cushioning effect.

Furthermore, the content of air pumped out of the vacuum bag is 90%, the vacuum bag is not in a hundred percent vacuum state, and the vacuum bag contains a small amount of air, so that the influence on the quality of fresh fruits and vegetables can be reduced.

Furthermore, the number of the ice bags is multiple and is divided into five groups, one group of ice bags are placed on the lower surface of the inner part of the heat preservation box, the remaining four groups of ice bags are placed on the four side walls of the heat preservation box, the ice bags play a role in cooling, the respiration and metabolic processes of fruits and vegetables can be inhibited, and the senescence of the fruits and the vegetables is delayed.

Further, the humidity in the incubator is 95%.

The invention also provides application of fruit and vegetable fresh-keeping, wherein the fruit and vegetable can be apples, honey peaches, oranges, lettuce and the like, picked honey peaches are placed into a vacuum bag, air is pumped out from the vacuum bag, low-concentration ozone and negative oxygen ions are injected into the vacuum bag, the vacuum bag is sealed, a cuboid-shaped heat preservation box is selected, ice bags are uniformly placed in the heat preservation box and on the inner side wall of the heat preservation box, and then the honey peaches are sequentially placed in the heat preservation box from bottom to top.

In conclusion, the working process of the invention is as follows: the staff prepares the insulation can, puts into the ice bag in the insulation can, puts into the vacuum bag with fresh fruit vegetables, and in a suitable vacuum bag was put into to a fruit vegetables, takes out the air in the bag, pours into low concentration ozone and negative oxygen ion into to the bag, puts the vacuum bag that is equipped with fruit vegetables in the insulation can one again, can put into two-layer or multilayer, and the insulation can is covered the lid alright in order to have transported.
