Description

DETAILED DESCRIPTION OF THE INVENTION

[0001] The present invention relates to a container for transporting edible asparagus for refrigerated transportation, which can maintain the freshness of edible asparagus conveyed to a consumer via a production area and a distribution channel for a long period of time. About.

[0002]

2. Description of the Related Art Conventionally, edible asparagus has been set up with its ears up in a refrigerated transport box, for example, a cardboard box, and the container is put in a freezing container, for example.
Stored or transported while maintaining the temperature at about 1 to + 5 ° C. In addition, edible asparagus imported from abroad is stored and / or transported in a refrigerated transport box which is required to have a fumigation hole having an area of 2.0% or more of the entire container. . However, in these methods, the edible asparagus hardens or dries the stem in less than one week, and the spikes open or rot by drying.

[0003]

Accordingly, an object of the present invention is to maintain the freshness of edible asparagus for as long as possible under the same conditions of storage or transportation by refrigeration as before, and The goal is to develop containers that can be transported with high freshness and delivered to consumers.

[0004]

Means for Solving the Problems The present inventor has conducted intensive studies to solve such problems, and as a result, has set ears up in a container.
Standed edible asparagus spike or higher
Only at the location is a hole in the side wall of the container where the fumigation gas enters.
Water absorption which is impregnated and impregnated with dilute aqueous sucrose solution
Edible for refrigerated transport, with a water-repellent rug placed on the bottom
It has been found that this problem can be solved by using a container for holding and transporting asparagus freshness .

[0005] The aqueous solution of sucrose used in the present invention is 8-0.5.
%, Preferably about 5 to 1%, particularly about 4 to 2%. If the concentration is too high or less than 1%, sufficient freshness retention results cannot be achieved. This solution is preferably used after slightly adjusting the pH to slightly acidic. The amount of the aqueous solution used is preferably such that the ground portion of the edible asparagus does not immerse in the solution in a state where the water-absorbent water-retentive rug has sufficient water retention. 0.15 based on
２．５2.5 ml / cm ³ , preferably 0.5-1.16 m
1 / cm ³ .

The water-absorbent water-retentive rug used in the present invention is a composite or laminate of a natural or synthetic nonwoven fabric, a cotton-like fiber or woven fabric and a nonwoven fabric or a cotton-like fiber, and absorbs and retains a dilute aqueous solution of sucrose. There is no limit as long as it can do. However, when the above-mentioned aqueous solution can retain water for a long period of time and edible asparagus is placed, the edible asparagus has a water-retaining power so as not to be extremely immersed in the aqueous solution and the cut portion of the edible asparagus bundle It is preferable that each asparagus has elasticity enough to come into contact with the rug in response to the irregularity. This rug can be placed simply by laying or pasting or attaching to the bottom of the container.

A hole into which fumigation gas enters (hereinafter referred to as a fumigation hole)
(Also referred to as fumigation hole) below the ears of edible asparagus, two weeks after storage, a lot of stem wilting due to cool air from the fumigation hole was found (see Example 2). . However, in addition to using a water-absorbent water-retentive rug and a dilute solution of sucrose , if a fumigation hole is provided on the tip of the ear or on the side wall of the container at a higher position, the stem does not wither even after two weeks, and the defect is lost. The rate was 0% (see Example 3). This is thought to be due to the fact that not only the chilled air does not hit the edible asparagus during refrigerated storage or transport , but also the humidity adjustment in the container has been achieved. Here, the fumigation holes mean all holes in which a gaseous fumigant may enter during fumigation .

[0008]

The location of the fumigation hole is as described above, but the opening ratio (2.0% or more required for fumigation in plant inspection at the time of import) is as small as possible from the viewpoint of humidity control. Better. By providing the fumigation hole in this way, this container can be used as a frozen container (set at + 1 ° C).
The humidity in the container is 83
It is kept almost constant at ~ 85%, which is about 5-8% higher than the humidity in the container. This is presumed to prevent edible asparagus from withering.

[0010] The present inventor further puts a commercially available ethylene adsorption film or a denaturation preventing film on the tip of edible asparagus and / or puts the denaturation preventing film on the whole or a part of the inner wall in the container. It has been found that higher freshness retention can be achieved by using a container which has been coated or used with a coating or adhesive which has been placed or attached by attaching or attaching or has been treated to prevent denaturation.

Accordingly, the ethylene adsorption film or the denaturation preventing film is placed on the tip of edible asparagus, and / or the denaturation preventing film is arranged by attaching or attaching the denaturation preventing film to the whole or a part of the inner wall in the container. An object of the present invention is also a method for maintaining the freshness of edible asparagus using a container coated or used with a coating or an adhesive which has been subjected to a denaturation treatment.

The ethylene-adsorbing film used in the present invention is a commercially available plant freshness retaining film, for example, a trade name: Primavera (Inpack Co., Ltd.).
The denaturation prevention film is a film for preventing protein denaturation, for example, a film containing cristobalite that has been subjected to electromagnetic wave treatment as a filler, for example, a trade name: Tasty Tasukutsun (Daicel Chemical Industries, Ltd.). As a container for preventing denaturation, there is a container using a coating agent or an adhesive containing a filler obtained by treating ceramic particles with an electromagnetic wave, for example, a corrugated cardboard (JP-A-62-292).
425).

This method achieves an extension of the freshness retention period by removing ethylene generated by spoilage of edible asparagus. In particular, the case where the denaturation-preventing film was placed on the tip or the case where the denaturation-prevention container was used was better than the case of the ethylene-adsorbed film, and surprisingly, the defect rate was 0% even after 2 weeks ( Example 2
reference).

A side protector is attached to the inner side wall of the container of the present invention to prevent contact between the edible asparagus and the side wall of the container, thereby removing water from the edible asparagus to the side wall caused by the contact between the edible asparagus and the side wall. Absorption movement can be prevented. This side protector is provided so that only a part of the tip or stem of edible asparagus is in contact with the side protector. If the side protector is made of a water-absorbing material, it is made non-water-absorbing by a coating agent or a coating material, for example, polyvinyl wrapping. Is advantageous.

The container for keeping freshness of edible asparagus of the present invention takes about two weeks from the manufacturer of edible asparagus, especially from an overseas manufacturer, to transport by ship, freight car, etc., and storage to distribution users, and then to the consumer. Even in such a case, it has become possible to provide consumers with fresh edible asparagus.

In each test, a container packed with 200 edible asparagus was stored in a frozen container (set at + 4 ° C. (Example 1) or + 1 ° C. (Examples 2 and 3)) and left for one week from the container. At the time of 2 weeks, 30 samples were taken at random and strictly performed a visual inspection, and the number of defectives relative to the number of inspections was expressed as a percentage. It was shown to. With respect to the third week, the deficiency rate was examined for the remaining amount of the specimen at the lapse of three weeks, and the results are shown in Table 1.

If it is good, it grows slightly even in the freezing container
The length increases and the cross-sectional area and weight of the stem also increase. Its growth
The greater the amount of vibration, increase in cross-sectional area and weight, the better
It can be said that the freshness state is maintained. However, it grows too much
Then, the nest tends to be bright inside the stem, so the growth is moderate (
Average elongation after 2 weeks: about 3-7mm, increase in cross-sectional area:
2-10mm ^TwoAnd bundle weight increase rate: 0 to 30%)
It is necessary. In order to measure these, a)
About 1 week, 2 weeks and 3 weeks
The changes over time were tested. Test method and test
The results are shown in Table 2.

One representative bundle is selected from each container. (1) Average length: The length of each selected sample is measured for the selected bundle, and the total length is divided by the number. Expressed as bundle average length.

(2) Cross-sectional area average: For the selected bundle,
The major axis and minor axis of the cut portion were measured for each sample, the cross-sectional area was calculated as major axis × minor axis × π / 4, and the total was divided by the number to express the average sectional area.

(3) Bundle weight: The selected bundle was expressed as the total weight of the bundle.

The gas also had a putrefactive odor, and was virtually totally damaged. In comparison,
Clearly good results were obtained when using saccharides. Among sugars, a 3% sucrose aqueous solution is the best,
Next, a 3% glucose aqueous solution and a 3% fructose aqueous solution were in that order. The sucrose aqueous solution adjusted to pH 6.5 has a higher pH
Slightly better results were obtained than with the aqueous sucrose solution adjusted to 7.5.

The change in the average length of edible asparagus is 2
Comparing the amount of elongation up to the week, it was demonstrated that the sucrose aqueous solution was the largest (5.4 mm) and the freshness was kept the most. Next, an aqueous fructose solution (3.0 mm), an aqueous glucose solution (2.8 mm) and water (2.5 mm) were arranged in this order.

The change in the average cross-sectional area is 1 when water alone is used.
At week, rot of the cut part progressed, the cross-sectional area decreased, and at week 3, about 60% of the cut part was decayed and could not be measured. In the case of an aqueous sucrose solution, the upholstery and luster are better at the first week than at the start of the experiment, and the freshness is better than that of the aqueous solution of other saccharides and water. Increase is small. In the case of other saccharide aqueous solutions, the rot was not formed at the cut portion after the second week, but nests were formed, so that the major axis and the minor axis increased.

[0030] The bundle weight was reduced in the case of water alone from the first week and only decreased after the second week. In the case of the sucrose aqueous solution, the bundle weight increased until the second week, and thereafter decreased, but the decrease was smaller than that of other saccharides. In the case of the fructose aqueous solution, the bundle weight increased until the first week and did not increase or decrease at the second week measurement. In the case of glucose aqueous solution, there was no increase or decrease until the first week, and then decreased.

From the above experimental results, when the saccharide aqueous solution was absorbed by the superabsorbent polymer and used as a rug,
It was found that edible asparagus can maintain good freshness, and particularly excellent results can be obtained when an aqueous sucrose solution is used.

EXAMPLE 2 Four rectangular fumigation holes (40 mm wide) with 70 mm from the bottom or top of one side of the same cardboard box as used in Example 1 and 50 mm from the side , Length 5
0 mm) (see FIG. 3). As a freshness maintaining aqueous solution, a 3% aqueous sucrose solution was used by impregnating the same superabsorbent polymer as used in Example 1, and then an ethylene-adsorbed film (trade name: Primaverer, Impack Corporation) or denatured Prevention film (Product name:
Delicious Tasukutsun, Daicel Chemical Industries Co., Ltd.) was placed on the edible asparagus spikes in the entire container, and the defect rate at 1 week, 2 weeks, and 3 weeks elapsed as in Example 1. , Length average, stem cross-sectional area average and change in bundle weight. In this experiment, the temperature of the refrigeration container was set to + 1 ° C. The results are shown in Table 3: a) 3% aqueous solution of sucrose, ethylene-adsorbed film b) 3% aqueous solution of sucrose, anti-denaturation film Table 3 | 1 week 2 weeks 3 weeks Ａ a) | Defective rate = 0% Defect rate = 16.7% Defect rate = 73. 2% │ Slightly withered stem part Slightly withered stem part Slightly withered stem part, │, but found to be defective, ears are good.

Considering that the hole is in an inconvenient place, using an ethylene adsorption film or a denaturation prevention film Good results if it can be estimated that the obtained.

In the first week, the freshness of the anti-denaturation film was very good as compared with the case of using the ethylene-adsorbed film, and the stalk and spike increased in tension and luster. Also maintained good freshness. Approximately 10% of the defects occurred in the second week, but the number of defects was smaller than in the case of using the ethylene adsorption film, and the number of defects in the third week was also small. When the denaturation-preventing film was used, the amount of elongation was larger than that of the ethylene-adsorbed film, and there was growth until the second week, and good freshness was maintained. With respect to the average cross-sectional area, when the denaturation-preventive film was used, the value increased significantly to +5.9 mm ^{2 in the} first week compared to the case of the ethylene-adsorbed film, and both the stems and ears increased in appearance. This tension was maintained for almost two weeks. Regarding the bundle weight, when the denaturation-preventing film is used, the amount of increase is larger until the second week than in the case of the ethylene adsorption film, and the decrease after the two weeks is smaller. The decrease in bundle weight may be due to too much cold air contact of the edible asparagus due to over-drilling of the fumigation holes or improper opening location.

Summarizing the above, it was confirmed that the ethylene-adsorbing film, particularly the anti-denaturation film, was useful for maintaining the freshness of edible asparagus. However, a lot of wilting of the stem near the fumigation air hole was found, and the amount of change in the bundle weight in the second week was larger than that in Example 1, and the position of the fumigation air hole played an important role in maintaining freshness. It is inferred that it is playing.

Example 3 In this example, an experiment was carried out in the same manner as in Example 1 using the same container and superabsorbent polymer used in Example 2. However, in this embodiment, unlike the case of the second embodiment, the position of the fumigation hole is located above the tip of the edible asparagus, and the upper side is 20 mm from the top, as shown in FIG. There are two 20 × 70 mm holes and three 20 × 35 mm holes on the other two sides. The opening ratio of the fumigation hole is 3.28%.

As a freshness maintaining aqueous solution, a 3% aqueous sucrose solution was used as in Example 2, and an experiment using an ethylene-adsorbed film as in Example 2 was conducted.
An experiment using a denaturation-preventing cardboard box manufactured according to Example 2 of Japanese Patent No. 425 is conducted. As in Example 1, the defect rate, the average length, the average cross-sectional area of the stem, and the change in bundle weight were measured at the lapse of one week, two weeks, and three weeks. The results are shown in Table 4.

This is due not only to the effects of the water-absorbent and hygroscopic rug, the aqueous sucrose solution, and the cardboard cardboard for preventing denaturation, but also that the position of the fumigation hole is a value close to the humidity of about 90% and the temperature of + 1 ° C., which are preferable for maintaining the freshness of edible asparagus. It is believed that the ability to maintain and keep cold air out of direct contact with edible asparagus achieves freshness retention of edible asparagus. Incidentally, the denaturation-preventive cardboard used in Examples b) and c) achieved the same effect as the ethylene-modified film or the denaturation-preventive film as described above.

Under the same conditions as in the experiment a) of this embodiment, the same experiment was conducted by placing the same container in the container, and the humidity and temperature in the container and the temperature and humidity in the container were measured. 83-85% within
It was found that this humidity was 8.1 to 5% higher than the humidity in the container, and the humidity measured every 12 minutes was almost constant.

[0039]

Effects of the Invention for the conventional container could not also stored refrigerated for 1 week edible asparagus, cold of the present invention
In the freshness-keeping transport container for storage, even for edible asparagus imported from abroad, a very low loss rate within 2 weeks,
Depending on the configuration, it is possible to carry and carry freshness with a defect rate of 0%.
