Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a quality preservation material that can be attached to a jar or the like to properly maintain the quality of heated cooked rice.

[Conventional technology and its problems]

BACKGROUND ART Jars have been commonly used as means for holding cooked rice, for example. Such a figure is
Keeps rice warm by keeping the temperature inside the rice bowl below about 70℃,
On the other hand, approximately 70
Because the rice is kept at a high temperature of ℃, browning of the rice, loss of aroma, and stuffy odor occur, resulting in a significant deterioration in the quality of the cooked rice.

This invention aims to solve the conventional problems at once and provide a quality maintenance material that can be attached to a jar or the like to ensure that the quality of heated cooked rice is always maintained.

[Means for solving problems]

That is, this invention consists of a structure in which a fibrous polymer absorber 2 contains an oxygen scavenger 3 and activated carbon 4.

[Effect]

Moisture generated in the rice bowl is absorbed by the polymer absorber 2, oxygen is absorbed by the oxygen scavenger 3, and foreign odors such as stuffy odor are absorbed by the activated carbon 4, and these actions work together to maintain the quality of warm cooked rice at all times. It can be held securely.

〔Example〕

An embodiment of this invention shown in the drawings will be described below.

Reference numeral 1 denotes a flat, approximately doughnut-shaped quality preservation material, which includes a pair of upper and lower fibrous polymer absorbers 2 in the form of a sheet, and an oxygen absorbing material built between the polymer absorbers 2. It is composed of an agent 3 and activated carbon 4. The polymer absorbent 2 may be, for example, acrylic fibers, cellulose fibers, polyvinyl alcohol fibers, etc. treated with water-absorbent modification, fibrous materials made from a dibasic acid copolymer such as maleic acid, or polyacrylic acid A material coated with a hydrophilic polymer such as soda can be used. In particular, carboxyl groups of 0.5 to
The fibrous polymer absorber containing 4.0 mmol/g has excellent water absorption capacity and physical properties such as strength and elongation.
Even under water-retaining conditions, the presence of the core not only makes it possible to maintain the water-retaining form stably, but also, for example, if the degree of neutralization of carboxyl groups is kept below 80%, the remaining acid-type carboxyl groups (-COOH) can be converted into ammonia,
It is extremely suitable because it can selectively adsorb amines and the like. In addition, as the oxygen absorber 3, ferroalloy, ferrosilicone, ferromanganese,
Silicon manganese, aluminum, or the like can be used, and as the activated carbon 4, known activated carbon such as powdered activated carbon or granulated activated carbon can be used. In addition, 5 is a jar, and the jar 5 includes a main body 6, an inner pot 7 that can be freely fitted into the main body 6, an outer lid 8 attached to the upper edge of the main body 6 via a hinge, and a jar 5 that is attached to the outer lid 8. It is composed of a pot lid 9 that can be attached to the inner surface of the pot, and a holder 10 for a quality maintenance material that can be attached to the inner surface of the pot lid 9.

The quality maintaining material 1 according to this invention is attached to the inner surface of a pot lid 9 via a holder 10, as shown in FIG. After that, the jar 5 is activated to keep warm. Then, the polymer absorber 1 removes the moisture generated from the cooked rice in the inner pot 7 as it is kept warm, and transfers it to the oxygen absorber 3.
The activated carbon 4 absorbs and retains oxygen, and the activated carbon 4 absorbs and retains foreign odors such as stuffy odor, and these actions combine to reliably prevent browning of the warm cooked rice, loss of aroma, and stuffy odor.

In the above embodiment, the quality maintaining material 1 has a flat, approximately donut shape, but it is not limited to this, and can have various shapes depending on the object to be attached. Even if one of the pair of fibrous polymer absorbers 2 is made into a heat insulating sheet, the object of this invention can be effectively achieved. Furthermore, it goes without saying that the quality maintaining material 1 according to this invention can be applied not only to cooked rice but also to maintaining the quality of other foods that require heat retention.

[Effect of idea]

According to this invention, as described above, the fibrous polymer absorbent material 2 is constructed by incorporating an oxygen scavenger 3 and activated carbon 4, so that moisture generated in the rice bowl is absorbed by the polymer absorbent material 2. To remove oxygen, use oxygen scavenger 3
In addition, the activated carbon 4 absorbs foreign odors such as stuffy odor, and these actions work together to reliably prevent browning of heated cooked rice, loss of aroma, and unpleasant odors such as stuffy odor, and always maintain appropriate quality. It is something that can be maintained.
