Description

Container for using by a storehouse}

The present invention relates to a container that can store food, and to maintain the freshness of vegetables and fruits and vegetables, as well as to neutralize the pesticides remaining on the surface, and to be configured to meet the fermentation conditions of fermented foods, such as kimchi It is about.

Containers are widely used for offices, lodgings, warehouses, etc. because they are convenient to move and can be used semi-permanently.

Among them, there is a storage container for storing and transporting vegetables and fruits and vegetables, and such conventional storage containers are stored with water or the like to be cleaned of pollutants on the surface of crops after harvesting the crops. Is stored inside the container, so that various bacteria and viruses in the air do not propagate to maintain antibacterial properties, so that the proper storage conditions are maintained at a room temperature of 5 ° C. to prevent mold or rot. The refrigeration unit is installed.

Looking at the conventional container for storage configured as described above it is possible to increase the storage period without being deteriorated vegetables and fruits and vegetables by maintaining a constant room temperature by simply providing a refrigeration device.

However, such a conventional storage container has a problem that it has only a simple function of storing vegetables and fruits and vegetables at a constant temperature, and exhibits improved performance and improves the quality of the storage to increase the value added of the container. Is required.

Freshness of crops is maintained after harvesting. Vegetables and fruits and vegetables are still alive and breathing after harvesting, and maturation and aging progress. This can be observed when the roots come out again when storing various vegetables, which is a symptom of growing.

The main freshness holding materials are as follows.

1) film packing

Selective gas permeability is used to control the concentration of moisture, carbon dioxide, oxygen, ethylene and the like in the film.

This is an easy freshness method at home. When fruits and vegetables are kept sealed in plastic bags, the oxygen concentration decreases and the carbon dioxide concentration rises, resulting in slow breathing. Aging) is suppressed.

2) Moisture Control

Maintain freshness and prevent wilting. Examples include silica gels, absorbent polymers, and the like.

3) deoxidizer

Rapidly lowering the concentration of oxygen improves storage of CA (Controlled Atmosphere). The CA storage is a method of suppressing respiration by setting the concentration of carbon dioxide higher than the atmosphere.

4) Ethylene Remover

Ethylene that accumulates during the CA storage is removed to prevent degradation of the aging salts. The action of ethylene is described in detail below.

Ethylene is a plant hormone made by plants that promotes the maturation of fruit. It plays a positive role in enhancing the taste of fruit and destroying chlorophyll, which makes the color taste good. It is a cause of deterioration of the quality by promoting rot and softening the tissues to decay or accelerate the penetration of pathogens.

If physical damage occurs due to inadequate management of the crop during harvesting, the amount of ethylene produced will increase significantly, so care must be taken to avoid stress from the harvest. In addition, ethylene acts on the surrounding fruits and vegetables as if it is an infectious disease, thereby rapidly promoting ethylene generation. Thus, when ethylene is removed from the early stage of pre-cooling, long-term storage is possible in a fresh state.

Even after harvesting, fruits and vegetables are alive for a while, breathing is activated by ethylene, APT content decreases, and chlorophyll and starch content decreases, leading to a drop in freshness. As a result, the ecological function is reduced, the antimicrobial properties are lost, and mold or rot occurs. Physiological action of ethylene is shown in Table 1.

Among the physiological effects of ethylene, a particularly maintenance problem is to turn yellow by aging and degradation of chlorophyll.

Table 2. Ethylene Generation in Fruits and Vegetables (Unit: μl / kg · h)

Amount And real Vegetable 0.1 or less Strawberry, Grape, Cherry, Lemon, Orange, Wine Citrus, Lime, Grape Fruits Spinach, lettuce, cabbage, green onion, carrot, onion 0.1 to 1.0 Olive, pineapple, Japanese pear, watermelon, Blue-berry Cucumber, eggplant, mallow, bell pepper, pumpkin 1.0 to 10 Banana, Mango, Melon, Tomato, Fig, Persimmon Cabbage, Broccoli, Bell Pepper 10-100 Apples, Plums, Peaches, Nectarines, Western Pears, Avocados, Papayas, Pigeons 100- Apricot, Kiwi, Plum, Tangerine, Chinese Pears

Table 2 above shows the amount of ethylene generation of various fruits and vegetables, but does not represent a constant value, but varies considerably according to physiological conditions and environmental conditions.

Hormones do not appear in fruits and vegetables with less than 1 μl / kg · h of ethylene production. Once maturation begins, chain reaction generates a large amount of ethylene. Indeed, the use of ethylene scavenger makes it possible to maintain ethylene concentration below the lowest level at which maturation can occur.

Commercially available ethylene scavengers can be classified into physical adsorption and chemical reaction types, and the removal methods are shown in Table 3 below.

Therefore, in order to solve the above problems, the present invention removes ethylene gas while maintaining a constant room temperature in order to maintain the freshness of crops such as vegetables and fruits and vegetables in the container in which the crops are stored, and the surface of the vegetables and fruits and vegetables. An object of the present invention is to provide a storage container configured to neutralize the pesticide component remaining in the container.
