JP2002281894A - Case for keeping freshness of vegetable and fruit - Google Patents

Abstract

PROBLEM TO BE SOLVED: To keep the freshness of vegetables and fruits in the distribution stage over a long period by simultaneously carrying out the suppression and removal of ethylene and the suppression of the proliferation of microorganisms at normal temperature. SOLUTION: A freshness-keeping agent produced by mixing hinokitiol or a cyclodextrin clathrate compound of hinokitiol with an ethylene adsorbent and a printing ink is applied to the inner surface of a case for holding the vegetables, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention suppresses and removes the production of ethylene and suppresses the growth of microorganisms.
The present invention relates to a storage case for maintaining freshness of fruits and vegetables.

[0002]

2. Description of the Related Art In the distribution stage, fruits and vegetables are stored in a case such as a cardboard box, stored in a production area, transported and stored in a consumption area, and then provided to final consumers in a different packaging form. About the preservation of freshness of fruits and vegetables in
Conventionally, for example, low-temperature storage method, CA storage method (environmental gas control), MA packaging, etc., the method of lowering the physiological function of the whole fruit and delaying ripening and aging, and the use of ethylene remover to produce ethylene A method has been used to prevent the promotion of maturation and aging by removing the aging.

[0003]

However, the low-temperature storage method has a drawback that, even if the physiological function is reduced, low-temperature damage is caused depending on the fruits and vegetables, and the CA storage method has a high cost. In distribution after storage, sufficient ripening and prevention of aging cannot be expected. Further, even if only an ethylene removing agent is used, a sufficient effect cannot be obtained, and at present, none of the above methods has obtained any effect in terms of suppressing the growth of microorganisms.

[0004] It is an object of the present invention to simultaneously suppress and eliminate the production of ethylene and the growth of microorganisms under the normal temperature environment for fruits and vegetables at the distribution stage, and maintain their freshness over a long period of time.

[0005]

SUMMARY OF THE INVENTION The present invention for solving the above-mentioned problems comprises forming a freshener obtained by mixing hinokitiol or a cyclodextrin clathrate compound of hinokitiol, an ethylene adsorbent and a printing ink on the inner surface of a case. This is a case for keeping fresh fruits and vegetables.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The ethylene adsorbent for realizing the present invention is composed of a porous fine powder, for example, zeolite (Oyaishi), silica, activated carbon and the like are preferable.

[0007] The freshness holding case is preferably formed of corrugated cardboard, but is not limited thereto.
It may be formed by molding white paperboard, synthetic resin, or the like into a container.

The freshener formed on the inner surface side of the case can be printed by a general printing method such as flexographic printing, silk screen printing, offset printing, gravure printing or the like.

[0009]

EXAMPLES The present invention will be described in detail below, but the present invention is not limited thereto. "Example 1" Tomato freshness retention test Four cardboard boxes with a canopy having a length of 430 mm, a width of 280 mm and a height of 80 mm were prepared, one was a non-treatment section, and three were treatment sections A, B and C. Formulations having the following composition adjusted for each section were formed on the inner surface side of each box by flexographic printing at 10 g / m ² .

[0010] Tomato (Ibaraki, varieties "Momotaro", one day after harvest) is about 4 kg (16-
20 pieces, each about 150 g to 200 g), and their changes over time were observed in a normal temperature environment from the viewpoint of mold, decay, wilting of pericarp, and ripeness. The observation results are as shown in Tables 1 to 4.

[0011]

[Table 1]

[0012]

[Table 2]

[0013]

[Table 3]

[0014]

[Table 4]

Table 5 shows the overall evaluation based on the above observations.
Of the evaluations in the table, ◎ indicates that gloss was maintained and mold was extremely good, and ○ was ripe without mold and was good, △ was mold,
Wilting occurs, x indicates rot.

[0016]

[Table 5]

In the non-treated plot, after one week had passed, in the treated plot A and the treated plot B, after 10 days, mold had developed and decay had started. In the treated plot C using the case of the present invention, Even after the elapse of 14 days, the state was very good at the start of storage.

[0018]

As described above, the use of the freshness preserving case of the present invention suppresses and removes the production of ethylene, thereby preventing the ripening and aging of fruits and vegetables and also suppressing the propagation of microorganisms. It was possible to maintain the freshness of fruits and vegetables for a long time.
