Description

The manufacturing method of food contained taurine using a waste water generated by cuttle treatment}

The present invention relates to a manufacturing method of taurine-containing food, in particular, squid stripping liquid and cooked food to recover the squid stripping liquid and cooked liquid generated in the squid processing process to produce a food containing taurine through several process steps It relates to a method for producing a taurine-containing product using a liquid.

In recent years, as the demand for squid processed products has increased, the amount of squids used as raw materials for processed products has increased greatly. Accordingly, a large amount of waste liquid has been generated during processing to produce squid processed products.

In particular, the waste fluid is discharged from the shelling tank for the stripping process of the squid and the self-tightening tank for the stripped squid. In particular, the amount of the stripping liquid and the cooked liquid is rapidly increased, which is a major problem. It has emerged.

The waste liquid contains a large amount of nutrients, and when the waste liquid is discharged into a river or ocean, the amount of dissolved oxygen consumed by the growth and respiration of microorganisms to break down the waste liquid increases, that is, biological oxygen Because of high demand (BOD: Biochemistry oxygen demend), there is a problem that acts as a cause of various water pollution and marine pollution, including eutrophication and red tide phenomenon.

In general, the waste liquid generated in the squid processing process contains a large amount of various essential amino acids including taurine, and the chemical formula of taurine is shown in Chemical Formula 1.

Taurine is a kind of amino sulfonic acid as shown in Formula 1, and has a melting point of 305 ° C to 310 ° C and is soluble in water. Particularly, pure taurine is colorless or white crystalline powder, which has no odor.

Taurine having the above characteristics is excreted in bile together with taurocholic acid containing bile acid and taurine in carnivore bodies, and taurine released as bile absorbs fat or fat-soluble vitamins in the intestine by interfacial action. In addition, it also has an effect of relieving jaundice during acute hepatitis and lowering the level of triglycerides and cholesterol in serum of hyperlipidemic patients.

Due to such physiological activity, taurine is used as a variety of health foods and medicines, such as baby food, gum, beverages, and nourishing tonic drinks, and in particular, the amount of taurine has increased significantly in recent years due to increased demand for drink.

There are natural taurine extraction methods and chemical synthesis methods for the production of taurine, which are used for various purposes. However, the handling of starting materials and intermediates is different depending on the manufacturer and the method. Japanese Journal Bio Industry, Vol. 12, No. 12, 1995) introduce general natural taurine extraction and various chemical synthesis methods.

The general natural taurine extraction method, which is the former, extracts taurine components from molluscs such as squid, octopus and shellfish in which taurine is present, and then decolorizes the extract with activated carbon and passes through ion exchange resins to obtain taurine components. To obtain taurine crystals, and then separate and purify and commercialize them.

However, the product produced by the natural taurine extraction method can be used for edible and medical purposes, but very small amount of about 1% compared to the entire taurine products, taurine products are mainly used by the chemical synthesis method.

The latter chemical synthesis method includes the first method of synthesizing taurine by reacting ethylene bromide, sodium sulfite and ammonia, and the second method of synthesizing taurine by reaction of ethylene imine and sulfite. The method of synthesizing taurine and the method of synthesizing taurine by using mono ethanol amine as a raw material are proposed.

However, other impurities may be included in the production of synthetic taurine, and impurities cannot be completely removed during the purification thereof, and thus their use is limited by the remaining impurities, especially in the case of cheap synthetic taurine. It cannot be used for food.

As described above, in the case of taurine products, artificial taurine is mainly used by synthetic methods, but its use is extremely limited, and thus the necessity of natural taurine for multi-use such as food and medicine is increasing. In particular, natural taurine products are chemically 20 to 40 times more expensive than the artificial taurine product produced by the synthetic method can be a high value-added product.

As described above, taurine, which can be used for food and medicine, and can be a high value-added product, is contained in a large amount of waste liquid generated in the squid processing process, but the technology for producing a taurine-containing product from the waste liquid There is a problem that the method is not solved and is discarded as it is.

The present invention is to solve the conventional problems as described above, the squid stripping liquid and cooked to recover the squid stripping liquid and the waste liquid generated in the squid processing process to produce taurine-containing products through a number of process steps Its purpose is to provide a method for producing a taurine-containing product using a liquid.

The present invention for achieving the above object is a filtration step of recovering and filtering the stripping liquid and the ripening liquid generated in the squid processing process; Placing the filtrate in a vacuum concentrator and concentrating the concentration of the solid component to about 10% in a temperature range of 40 ° C. to 50 ° C .; Squid stripping and cooked liquid, comprising a powdering step of adding a powdered material dextrin at a ratio of 4 g to 7 g per 100 ml of the stock solution, and spraying the concentrate with a spray dryer at 45 ° C. It can be achieved by providing a method for producing a taurine-containing food using.

First, in the present invention, the stripping liquid discharged after being treated in the stripping tank for about 20 minutes, and the squid stripped in the stripping tank are subjected to a filtration step of recovering and filtering the ripening liquid obtained in the course of ripening in a self-contained tank.

The filtration process is performed to remove various fine miscellaneous substances present in the squid stripping liquid and the cooked liquid and to remove solids such as heat-solidified protein. The liquid is simply dehydrated using a centrifuge in the form of a centrifugal dehydrator. Although it may be used as a filtrate, in order to process a large amount of raw material liquid, it can be filtered using a filter cloth, and can be filtered by various methods.

The squid stripping liquid and cooked liquid contains various essential amino acids including taurine. Table 1 below shows the components and contents of amino acids contained in 1 kg of squid stripping liquid and cooked liquid, respectively, by HPLC.

ingredient Squid skin peeling liquid (g) Squid self-serving liquid (g) TauProIleLeuPheGluTrpValAlaMetAspGlyTyrGlnThrArgAsnSerHisCysCys2 13.69.35.42.41.32.22.11.52.31.61.51.11.51.31.11.31.30.60.50.10.5 15.89.57.42.01.11.71.61.12.00.70.71.11.10.61.11.10.10.80.70.10.2

As shown in Table 1, 1 kg of squid stripping liquid and cooked liquor contain a large amount of taurine, and in particular, the content of various amino acids including essential amine nosane of proline (Pro) and isoleucine (Ile) It is high.

The filtrate having the content as described above is subjected to the following concentration process, the concentration process according to the present invention to put the filtrate in a vacuum concentrator so that the concentration of the solid component in the temperature range of 40 ℃ to 50 ℃ about 10% It is to concentrate.

At this time, if the concentration temperature is less than 40 ℃, the concentration time is excessively delayed, resulting in a decrease in productivity. If the concentration temperature exceeds 50 ℃, the concentration time can be shortened. Since the problem occurs, the concentration temperature is preferably 40 ℃ to 50 ℃.

At this time, the reason for the concentration of the solid component of about 10% in the concentration process is to facilitate the following powderization process.

When the concentration process is completed as described above is subjected to the following powdering step, the powdering step is added to the concentrated solution concentrated in the concentration process in the ratio of 4g to 7g per 100ml of the powdered material dextrin, the concentrated solution Spray drying in a spray dryer at 45 ℃.

At this time, the powdering by adding the powdered material to the concentrate to compensate for the disadvantages of the original liquid, in particular to prevent the deterioration during the distribution process, reduce the distribution cost, and also to remove the remaining odor according to the powdering method Because it can be powdered.

In particular, the powdered material dextrin does not need to exceed the ratio of 7g per 100ml of the stock solution, but rather acts as a cause of increasing the production cost, and when the powdered product is added at a ratio of less than 4g per 100ml of the stock solution, Since the problem of deterioration will occur, the amount of dextrin is preferably added 4g to 7g per 100ml of the stock solution.

The powdering process may be a powdering method by hot air drying in addition to the powdering method by spray drying described above, and it is preferable to spray dry to remove odor and to prevent discoloration of the powder product. And spray drying at a temperature of 45 ° C. or less in order to prevent discoloration.

Hereinafter, the present invention will be described in more detail with reference to the following examples, but the present invention is not limited to the following description.
