Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a release agent for food casings.

More specifically, the present invention relates to a release agent applied to skinless cellulose casings and the like.

[Conventional technology]

Among processed foods, small-sized sausages such as Wiener sausages and frankfurters are processed through the processing of meat emulsions into artificial casings made from animal fat, regenerated cellulose or other cellulose derivatives, alginates, flagens, etc. After filling, it is subjected to processing such as smoking and shoeking. There are two types of finished products: those that are supplied to the market as they are, and those that are supplied after the casing is removed and only the processed food contents are left.

The latter is skinless sausage.
It is a product developed in recent years for the purpose of mass production through mechanization. The main machines used to manufacture this product are a high-speed automatic filling machine and a peeling machine, but the casing used must also be adaptable to these machines.

Specifically, in the production of small-sized sausages,
First, raw meat such as pork or beef is ground, and seasonings are added to this.
Spices and other ingredients are added and kneaded, and the meat emulsion thus prepared is filled into a casing using a stuffer and shaped into a predetermined size. The machine used for this purpose is a high-speed automatic filling machine, for which the casing is usually shirred with a cylindrical material with a length of 17 to 48 m and compressed to about 20 to 4 ocn (stick). or strands). The mechanical suitability of this stick in the filling process requires that the stick exhibits predetermined properties such as inner diameter, straightness, self-holding ability, release of pleats, lubricity on the inner and outer surfaces, and strength.

The semi-finished products that have been completely filled are subjected to all processes such as drying, smoking, and shoeing according to the technology in the industry, and after cooling,
An operation is carried out to remove the casing from the meat content. The machine used for this work is a beer ring machine,
The top surface of the sausage links running at high speed is torn apart in the direction of flow with a sharp knife, and the torn casings are separated with compressed air and either rolled downwards or sucked into a vacuum chamber. In this case, the delicate state of adhesion between the meat and the casing determines whether or not the peeling process can be carried out smoothly.If the peeling property is poor, the casing will not be easily separated from the meat inside, and may get caught on the way. It targets the smooth flow of work.

This peelability is affected by the raw meat used and the content of additives, as well as the manufacturing conditions of the processing process, so sausage manufacturers must satisfy the peelability as much as possible while taking other quality characteristics into consideration. You have selected conditions that will allow you to do so. However, with machines that have become faster these days, it is not possible to perform smooth peeling work by simply setting these fz fitting conditions, and it is necessary to actively apply treatments to the inner surface of the casing to promote peelability. By doing this, work efficiency has been improved.

Various stripping agents have been proposed for this purpose, and stripping agents containing particularly good water-soluble cellulose ether as one component are commonly used. When used, there is a problem of sticking of the treated casing pleats together. If this adhesion force is large, tearing occurs due to partial adhesion during deshering (releasing the fillet), which seriously impedes the filling operation. Therefore, it is essential to add an anti-sticking agent to the release agent.

Various types of anti-sticking agents have been proposed in the past, including animal oils, vegetable oils, mineral oils, silicone oils, alkylene oxide adducts of water-soluble fatty acid partial esters (Japanese Patent Publication No. 53-20578), and olein. Acid monoglyceride-diglyceride mixture (JP-A-51-63
No. 962), partial fatty acid esters of polyhydric alcohols (Nete Publication No. 70466/1983), wax (Japanese Patent Application Laid-Open No. 1983)
9-98646), phospholipids (JP-A-59-55
However, water-soluble anti-sticking agents have low anti-sticking ability, and water-insoluble ones have poor dispersion stability and stability of prepared aqueous dispersions. Viscosity is a major practical limitation.

[Problem that the invention seeks to solve]

In order to solve these drawbacks, the present inventor further investigated aqueous dispersion-based stripping agents. As a result of extensive research, we have found that this problem can be effectively resolved by using a water-insoluble, ie, low HLB, sucrose fatty acid ester.

[Means for Solving the Problems] and [Operation] Accordingly, the present invention relates to a release agent for food casings, and this release agent for food casings comprises a water-soluble cellulose ether, HL.
B 2.5 or less shio sugar fat u 0 ester anti-sticking agent,
It consists of an aqueous dispersion of an emulsifier and a polyol.

Examples of water-soluble cellulose ethers used include methylcellulose, ethylmethylcellulose, hydroxyethylcellulose, hydroxyglobilcellulose, hydroxyglobilmethylcellulose, ethylhydroxyethylcellulose, carboxymethylhydroxyethylcellulose, and especially carboxymethylcellulose ( OMO ) is most preferred. It is commercially available as IJium salt, and has an average degree of substitution of carboxymethyl groups per anhydroglucose unit of cellulose of 0.4 to 2.0, and a viscosity of a 2% aqueous solution of about 10 to 2.0. 5Q cps (25°C) is suitable.

As the sucrose fatty acid ester with an HLB of 2.5 or less, preferably 2 or less, palmitic acid or steric acid esters of sucrose are used, and di- and triesters are used based on their HLE values. Used1. If a material with an HLB higher than this is used, various problems will occur in terms of the anti-sticking effect as described above.

Various emulsifiers can be used, but polyoxyethylene alkyl ethers, polyoxyalkylene polymers, and the like are particularly preferred.

Polyoxyethylene alkyl ethers are preferably those in which carbon FJ of the alkyl group is 18 to 22 and the number of moles of oxyethylene added is approximately 10 to 30. A copolymer of ethylene and propylene oxide, preferably a block copolymer having a molecular weight of about ioooo to 16,000, in which ethylene oxide is copolymerized at a ratio of about 70 to 80% by weight, is used.In addition to this, as an emulsifier, , polyoxyethylene sorbitan fatty acid partial ester, polyoxyethylene alkylphenol ether, dialkyl sulfosuccinate, etc. are also used.

Further, as the polyol, for example, glycerin, glopylene glycol, triethylene glycol, polyethylene glycol, and sorbitol are used.

The concentration (wt%) of each of these components in the entire aqueous stripping agent dispersion will vary depending on the type of casing being treated, the treatment and the row 1'1.
:Although not necessarily constant depending on factors such as, -I12 contains 0.2 to 2.0% of water-bathable cellulose ether, preferably 0.5 to 1.6%, and 1 to 5% of anti-sticking agent, preferably (. The emulsifier is 0.3 to 3.0%, preferably 0.5 to 1.0%, the polyol is 20 to 80%, preferably 50 to 70%, and the remaining portion is water.

The 6 degree of water-soluble cellulose ether also depends on its degree of polymerization, and those with a low degree of polymerization have inferior peeling performance than those with a high degree of polymerization, so those with a low degree of polymerization have a high 201 degree, and conversely those with a high degree of polymerization have a high 201 degree. It is necessary to lower the concentration. Furthermore,
Those with a low degree of polymerization tend to have a higher density and 4 degrees than those with a high degree of polymerization, and as the degree of polymerization increases, the viscosity of 3V due to humidity increases, so these peelings are caused by adhesion,
It is important to select the most appropriate combination based on comprehensive judgment including the concentration of the stripping agent. If the density is lower than the density range σj3 selected from such red points, substantially N

! Arrival. This will cause the vessel to become too large, which will completely impede filling suitability. The most preferred embodiment is a 2.0% aqueous solution having a viscosity (25°C) of about 10 to 40 cps. s~1
．． When used within the range of 6%. For example, the higher the degree of polymerization and concentration of carboxymethyl cellulose, the better;
2% aqueous solution viscosity is 15 cpsD, casing 1
A treatment of 0.003 m7 per cJ shows excellent πε peelability from processed sausages.

Regarding the adhesion prevention agent, if it is used at a concentration lower than this, the adhesion prevention effect will be substantially reduced, breakage will occur during deshiring, and filling suitability will be hindered by 1g. On the other hand, if the concentration is higher than this, the viscosity of the release agent increases (-), which not only causes problems in operation, but also reduces the degree of adhesion and deteriorates handling properties during use.

Regarding the emulsifier, when the concentration is lower than this, the viscosity of the stripping agent increases, which becomes a problem in operation, while when the concentration is higher than this, an adverse effect on the peelability9 is observed. Furthermore, regarding polyols, v'! ! If the t r k is higher than this, the viscosity will increase, which will cause operational problems.On the other hand, if the concentration is lower than this, there will be a relatively large amount of water, which will increase the frictional resistance on the mandrel and hinder the feeding of the shirring casing. This also increases the relaxation of the folds upon release of compression, causing the stick to bend.

The release agent aqueous dispersion containing the above-mentioned components as essential components is prepared according to a conventional method.
In order to reduce the frictional resistance between the gathered sticks and the shearing machine mandrel, a water-soluble or water-insoluble liquid lubricant can also be included.

The release agent is applied to the casing as described below, and the amounts of the above-mentioned components applied per 1 crl of the casing are as follows.

Water-soluble cellulose ether: o, ooi~o, oism9, preferably 0.003~
0.01 rny anti-sticking agent: 0.006-0.03 drops, preferably 0.01-0.0

0.006 m9 polyol: 0.12-0.48 mg, preferably 0.30-0.
42 mg water: 0.12-0.48-, preferably I'j: 0.18
~0.309 Methods for applying the release agent to the casing include a method in which the release agent is injected into the inside of the casing immediately before the dryer, and the excess amount is squeezed out and dried (slugging method), and during shear linking. A method of spraying a release agent on the inner surface of the casing using a mandrel (spray method),
Stripping i+ during the final wet tank bath! ! A method in which a release agent is added to the viscose stock solution prior to molding the casing (DO) and a release agent is added to the viscose stock solution prior to molding the casing (
[Effects of the Invention] When the release agent according to the present invention is applied to food casings, particularly cellulose casings, sucrose and fatty acid esters can be used as anti-sticking agents. The adhesion prevention effect is sufficiently exhibited over a wide range of applications, and the peeling performance is also good.
