[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a film for coating a paste product for adding post-treatments such as coloring, coloring, aromatizing, seasoning or improving shelf life to paste products of livestock meat, poultry or fish meat.

[0002]

[Prior Art]

  Background of the Invention For example, a film or sheet made of a resin having low gas permeability such as polyvinylidene chloride (PVDC) is coated with a coating film on one surface of which a edible dye, a flavor or a preservative is dispersed. Is conventionally used for the purpose of adding post-treatments such as coloring, coloring, perfuming or improving shelf life of kneaded products such as ham, sausage and kamaboko, and the final product may be packaged directly with this film. ..

Problems of the Prior Art However, for the above coating operation, it is necessary to first make the resin serving as a vehicle into a solution, and for this purpose, a solvent is required. As the solvent, lower aliphatic alcohols, lower fatty acid esters, lower aliphatic ketones, etc. are used as the solvent, but since the resin film is generally highly hydrophobic, a hydrophilic solvent such as lower aliphatic alcohol is used. A resin that dissolves in water cannot dissolve a sufficient amount of resin, and the resulting coating film does not have a good binding property to the film. Therefore, lower fatty acid esters and lower aliphatic ketones are usually used as solvents, but since this kind of weakly hydrophilic solvent is not a food additive, it is assumed that the solvent will be completely completely removed in the drying step after coating. Even if it volatilizes, it cannot be said to be preferable in terms of food hygiene.

Another problem associated with the use of weakly hydrophilic solvents is that this type of solvent is not a good solvent for additives such as water-soluble dyes and seasonings. That is, it is difficult to uniformly disperse the resin in the resin layer. Therefore, as a result of particles of the additive causing pinholes in the resin layer, uneven transfer occurs on the surface of the processed meat, and flesh (adhesion to the surface of the processed meat) is poor. Therefore, it is not possible to include a sufficient amount of additive.

[0005]

[Problems to be solved by the device]

 In view of the above circumstances, the present invention is not only safe from the viewpoint of food hygiene, but the water-soluble additive is completely dispersed, and uneven transfer does not occur on the surface of processed meat to be processed. To provide a film for coating a kneaded product of good quality.

[0006]

[Means for Solving the Problems]

  Concept In order to achieve the above object, the present invention provides an intermediate layer having an affinity with the film on one surface of a synthetic resin substrate film, and an ethanol-soluble material having an affinity with the layer on the outer surface of the intermediate layer. The gist of the present invention is a film for coating a kneaded product, which is characterized by comprising the edible vehicle layer. Below, the various elements that make up the device will be explained by section.

Synthetic Resin Base Film In the present invention, the synthetic resin forming the base film is a plastic material commonly used for food packaging, such as vinylidene chloride / vinyl chloride copolymer, vinylidene chloride / vinylidene chloride. A single-layer or laminated film made of acrylonitrile copolymer, plasticized polyvinyl chloride, rubber rubber, polyethylene, polypropylene, polyethylene terephthalate, polyamide, ionomer, etc. is used. A film or sheet made of vinylidene / vinyl chloride copolymer is particularly preferable in terms of heat resistance and gas permeation resistance.

Intermediate Layer As the intermediate layer, a synthetic resin having compatibility with both the base film and the below-mentioned ethanol-soluble vehicle is used. As the synthetic resin, a resin soluble in an organic solvent, for example, alkyd resin; polyvinyl chloride; vinylidene chloride / vinyl chloride copolymer; vinylidene chloride / acrylonitrile copolymer; vinyl chloride / vinyl acetate copolymer; polyvinyl Formal or polyvinyl butyral; polyvinyl acetate, polyacrylic acid ester or polymethacrylic acid ester or their copolymers; cellulose acetate or propionate; coumarone / indene resin, polybutadiene, etc. It is not limited to the ones. Depending on its solubility, this resin is dissolved in a solvent such as an aromatic hydrocarbon, a lower fatty acid ester, a lower aliphatic ketone or a lower aliphatic alcohol, and is applied to one surface of the base film. It is preferable that the base film also has a property of dissolving or swelling to some extent. A thin film having a thickness of about 1 to 5 μm is sufficient for this layer.

Ethanol-soluble edible vehicle The ethanol-soluble edible vehicle is located in the re-upper layer of the film for coating the kneaded product of the present invention, and retains the released components such as edible dyes, coloring agents, flavors, seasonings and preservatives. At the same time, it has an action of closely adhering to the meat paste product to be coated. Since this layer is in direct contact with the kneaded product, it must be not only soluble in ethanol but also highly safe to ingest. Appropriate in this respect are cellulosic polymeric substances such as acetyl cellulose, acetyl butyl cellulose, capryl cellulose, nitrocellulose, methyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, cellulose acetate phthalate, carboxymethyl cellulose; Polyvinyl acetate, polyvinyl butyral, acrylate / polyvinyl acetate copolymer, polyamide (nylon type); prolamin proteins such as gliadin, zein, hordein, etc .; and various natural resins such as shellac, rosin, copal, dammar, Kirin ashes and the like are exemplified.

Among these, shellac is a material that has long been used as an enteric coating for enteric coated tablets in addition to being used as a main component of varnish for a long time, and its safety is very high. The same applies to wheat proteins such as gliadin, zein and hordein. Furthermore, since Kirin ketsu is also used as a component of varnish, and the red one is also used for coloring varnish, it is suitable for the purpose of giving the film of the present invention a red appearance.

Additives In the ethanol-soluble edible vehicle layer, various water-soluble edible pigments, particularly red-based pigments (which may partially include oil-soluble pigments) and color formers ( For example, nitrites, flavors (including smoked liquid), seasonings (including spices), preservatives (eg sorbic acid), etc. are added. Further, if necessary, an anti-blocking agent such as silicic acid anhydride or microcrystalline cellulose and a stripping agent (meat adjusting agent) such as lecithin, fatty acid monoglyceride, sorbitan fatty acid ester, fats and oils can be added.

Production In order to industrially produce the film of the present invention, while continuously moving the substrate film, the intermediate layer forming resin solution is applied using a coater and dried in a drying oven. Using another coater, apply an ethanol solution of the ethanol-soluble edible vehicle and dry. The ethanol here does not have to be anhydrous, but rather is preferably hydrous ethanol containing a relatively small amount of water. This is because anhydrous ethanol is unsuitable for dissolving prolamin-type proteins such as zein, and it is rather preferable to contain some water to dissolve water-soluble dyes, water-soluble seasonings, preservatives, etc. is there.

The above-mentioned additive component may be dissolved or dispersed in the vehicle solution from the beginning, or on the viscous coating surface before the solvent component in the vehicle solution evaporates. It may be sprayed. Generally, the water-soluble dye is dissolved in the vehicle solution, but powder such as spice or anti-blocking agent which is difficult to dissolve in ethanol is preferably applied by a spraying method.

Usage method After filling the processed meat material using a stuffer inside a tubular shape molded by a welder such as high frequency, ultrasonic wave, hot plate, etc., sterilization treatment such as boiling, retort heating, oven heating and shaping Treatment, and if necessary smoke treatment. The kneaded product such as ham and sausage obtained here may be used as the final product as it is, or may be once peeled off and then again packaged with a packaging material such as cellophane.

[0015]

[Action]

 In the film for coating a kneaded product according to the present invention, since the intermediate layer is separated from the vehicle layer of the surface layer containing the additive component such as a dye, a trace amount of the organic solvent is temporarily contained in the intermediate layer coated with the organic solvent. Even if it remains, it does not contact the processed meat layer at all. Since the vehicle layer is formed by using ethanol, which is safe for food, as a solvent or a dispersion medium, it has a very high degree of safety in terms of food hygiene. In addition, since the vehicle layer is made of an ethanol-soluble hydrophilic material, even if the vehicle layer contains a sufficient amount of additives such as dyes and seasonings, the transfer state to the kneaded product is good. Not only that, but the adhesiveness to the surface layer of the product is good, and therefore the adhesiveness (fleshing) is very good. Therefore, when cooled after boiling, there is a risk that gaps will form between the product and the kneaded product inside. Absent. However, when the film is peeled off because the adhesiveness is so strong that the surface layer of the product is peeled off, the degree of adhesion can be adjusted by using the above-mentioned release agent together.
