JPS59179560A - "miso" (fermented soybean paste) powder - Google Patents

Abstract

PURPOSE:A MISO powder for plastic moldings that is prepared by kneading a plastic together with a MISO powder to remove the odor characteristic in polyolefin, thus being suitable for use in making food vessels or containers. CONSTITUTION:A plastic is kneaded together with a natural MISO powder. In addition to MISO, preferably sodium glutamate and mannan are admixed. As plastic, polyethylene or polypropylene is used. The resultant powder is made into films, sheets or vessels.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to plastic molding pellets, particularly miso powder for plastic molding characterized by kneading natural miso powder.

Generally, food packaging materials include paper, plastic, glass,
It is well known that various materials such as ceramics and metals have been used since ancient times. Recent product miniaturization,
Due to weight reduction and the rapid spread of disposable containers, the use of disposable paper containers for instant food containers is gradually increasing, and along with this, paper containers are increasingly being laminated with plastic and glue. Plastic materials such as polyolefin resins such as polyethylene and polypropylene cannot be used because their unique odor significantly interferes with the flavor of the product, and PET (polyethylene terephthalate) is used to prevent the flavor of foods from being affected. Due to the fact that we have no choice but to use expensive plastic materials, and with the recent spread of vending machines, it is necessary to improve the chemical properties and unique odor of packaging containers in order to spread the use of paper containers and paper containers. There is a trend that the necessity of using inexpensive plastic materials is being pointed out.

The purpose of the present invention is to solve these problems pointed out in food packaging materials such as paper and plastic. The object of the present invention is to provide a novel plastic material for food packaging. Yet another object of the present invention is to provide a novel food packaging plastic material in which the flavor of the food self-sealing contained therein is enhanced by the packaging material used, further increasing its product quality. Another purpose is to replace expensive plastic materials such as PET? The object of the present invention is to provide a new plastic material in which polyethylene and polynolopyrene can be used.

As a result of investigation, the present inventor found that a film obtained by cross-mixing a film for lamination of polyolefin resins such as polyethylene resin and polyzolopyrene resin with dried miso powder having a particle size approximately the same as the thickness of the film. It was discovered that the sheet eliminates the odor peculiar to polyolefin, and that by incorporating other main ingredients of sake other than miso, an excellent plastic packaging material that does not impair the flavor of miso can be obtained. In addition, as a result of examining film types, film thickness, sake lees content, etc., we found that by applying the same treatment not only to polyolefin resins but also to various other resins, the properties of food plastics and packaging materials could be significantly improved. By using it not only as a film sheet but also as a pellet for molding, similar results can be expected for all kinds of plastic molded products, and any molding method such as injection molding or blow molding can be used. I know that it can be applied.

That is, the present invention relates to pellets for molding two sticks of ore, especially plastics characterized by being mixed with natural miso powder, and miso powder for molding, which contains a large amount of miso powder. Various components of miso are leached into the infusion solution, and in particular, in addition to amino acid compounds, which are the main components of miso, desired results can be easily obtained by adding and mixing all of the ingredients, such as glutamic acid, mannan, etc. This has become possible.

In general, miso has the components (wt%) as shown in the table below, carbohydrates are high in dextrin and maltose, the coloring component is melanoidin, and the aroma is thought to be based on β-methylmercazotonorobionic acid ether. In addition to salt, the taste is thought to be imparted by the sweetness of maltose and glucose, as well as amino acid-based non-protein arthrobiotic compounds.

The miso glue for plastic molding of the present invention may be used in the form of a laminate film for disposable food containers, metal containers, etc., or it can be formed into a thin film as a food container and used as an outer holding material. The content of contaminants such as sake lees is not particularly limited, but is preferably 5 weight or more. Furthermore, depending on the type of f') stick used and the product field to which it is applied, for example, low-density polyethylene is used for 2-laminate film sheets such as TBA, paper, 7°, etc., and low-density polyethylene is used for molded containers. Various polynolopyrenes and the like can be suitably used. It goes without saying that the film sheet made from the molding powder of the present invention can be used as a single layer, but it can also be used in combination with various materials, as a double layer,
By using it as a three-layer, four-layer, etc. laminate film, the range of application as food containers can be significantly expanded.

Examples of the present invention are shown below.

Example 1 A film sheet with a film thickness of 20 μm was made by molding polypropylene cross-wired with a content of 25% by weight of natural miso powder into a 20 μm thick film, and this was laminated with a barrier film. When the obtained multilayer film was applied to the surface of a paper cup for vending machines and analyzed by hot water leaching gas chromatography, the elution of miso components was observed.

Example 2 When kneading dried natural miso powder, sodium glutamate j% was mixed in, and polyethylene F was used and laminated on the inner surface of a paper cot in the same manner as in Example 1. In addition to component 1, a large amount of sodium glutamate was observed to be eluted.

Example 3 Polyethylene fillo with a film thickness of 20 μm and a particle size of 20 μm
A molded container obtained by kneading 2% of dried natural miso powder crushed to about μ size with 1% of sodium glutamate powder and 1 batch of mannan powder, pelletizing it, and pasting it on a three-layered Kuraray enoral film. As is known from the above examples, the miso of the present invention/4' has no odor and has no flavor as an instant miso soup.
It is clear that the various glass products obtained by using Uda have significant advantages over conventional products, not only as laminate films such as paper cots but also as special packaging materials for various miso containers. be.
