JPH1142015A - Hibernant storage at low temperature - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a method for hibernant storage at low temperatures, in view of the fact that any biological material is subject to oxidation on coming into contact with oxygen, so intended as to shield a biological material from oxygen by the aid of nitrogen gas instead of a vacuum to prevent the material from being deteriorated and stop its growing activity with neither impairing the pigment contained therein nor decreasing its weight. SOLUTION: An article to be stored held in a flexible sealing bag such as of polyvinyl chloride of a closed vessel 1 is evacuated of air which, in turn, replaced with nitrogen gas and a small amount of quicklime 2 is put into the container, and the while of the above is put into another container and sealed, and then preserved in a refrigerator at 5 deg.C. This method is characterized in making use of nitrogen gas.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for storing low-temperature fresh foods such as shiitake mushrooms from forests and agriculture for a long time by using nitrogen gas and quick lime.

[0002]

2. Description of the Related Art Conventionally, storage of shiitake mushrooms and the like has been a drying method of drying at a high temperature in a drier and storing in double in a nylon bag. Preservation of other perishables also required large-scale cold storage and refrigeration facilities, making it difficult to preserve fresh foods for long periods of time.

[0003]

Conventionally, shiitake mushrooms and the like have only a raw shipping and drying method, which is disadvantageous due to limitations in distribution. Long-term preservation of other perishables must rely on large-scale facilities, and their use is limited. This method can be carried out with very simple facilities and methods, and can be brought to the end of distribution with the method implemented. Also, mass processing is possible. In addition, the cost is extremely low and the conventional disadvantages are solved,
There is a feature that can be widely used for fresh products.

[0004]

The article to be preserved is put in a soft bag or container such as vinyl, and a small amount of quicklime is put in another bag and enclosed. Glue a bag or container made of vinyl or the like, leaving a hole for bleeding air, gently bleed the air inside, and immediately seal with nitrogen gas. After the above treatment, it is put into another container, sealed again, and stored at a constant low temperature.

[0005]

Embodiments of the present invention will be described below. First step: Put the preserved product in a soft bag or container such as vinyl, and put quicklime in a breathable bag and enclose it without touching the preserved product. The enclosed ratio is as follows. Preserved bag capacity 18 liters of quicklime per 18 liters 100 g 2nd step A bag or a container made of vinyl or the like is bonded with an electric bonding machine, leaving a hole for bleeding air. Third Step Next, the inside air is lightly evacuated, nitrogen gas is introduced and replaced with air, and then the holes are adhered with an electric bonding machine and completely sealed. Fourth Step The above-mentioned treatment is put in a container made of poly or resin, sealed with a cloth tape, and stored in a refrigerator at 5 ° C. Above, the residual oxygen is completely treated by the synergistic effect of the radioactive substance and the ion, the substance and oxygen are cut off, the pigment is not damaged and the weight is not reduced. It is possible.

[0006]

According to the present method, matsutake, which has been considered impossible in the storage history, is 15 days, shiitake mushrooms are 1 month, tulip and other flowers are 3 months, and seafood grains are fresh for a long time. The ultimate storage method that is guaranteed and applies to all fish. It is to be noted that the embodiment is extremely simple, the equipment and materials are inexpensive, the cost is low, and there is no problem in terms of profitability. Furthermore, it can be transported to the end of distribution with processing, so it is very strong.
Utilization of nitrogen gas is the point of the present invention, which makes it easy to store all the raw materials.

Claims (1)

[Claims] 1. A preservation product and a small amount of quicklime are put in a soft bag or container such as vinyl, and the inside is evacuated. Instead, nitrogen gas is injected and sealed, and then put into another container. A low-temperature hibernation storage method in which the fresh products of forestry, agriculture and fisheries are stored in a fresh state for a long period of time after being resealed and stored in a low-temperature refrigerator.
