Description

Dried water of fast drying water and its manufacturing method {DRIED MATERIAL OF WATER-SWELLABLE AGAR AND PROCESS FOR PREPARING THE SAME}

1 is a process chart related to the manufacturing method of a conventional traditional silk agar.

Figure 2 is a process diagram for a method for manufacturing a dry ceiling of a real ceiling according to an embodiment of the present invention.

 The present invention relates to a dry agar with a rapid water swelling and a method for manufacturing the same, and more particularly, by mixing a gum dissolving solution that melts well in cold water with a flat starch extract at a constant ratio, the swelling speed is faster and texture than the conventional real agar. It relates to a process for producing this good dry matter and to a dry matter produced therefrom.

In general, silk hancheon is extracted with water, and then filtered through a clear solution, the solution is put into a fixed container, hardened, cut into noodles, and freeze-thaw is repeated by using the temperature difference between day and night. have.

1 is a process chart of a conventional method for manufacturing a traditional silk agar, the manufacturing method is as follows.

After washing the dried woodworm sufficiently with water, add about 20 times of purified water to the raw material and hang at 100 ° C. for 2 hours to allow the agar to sufficiently elute from the woodworm. After elution, add perlite and filter. The clear liquid is placed in a small molding box, hardened, cut into noodles, and placed in a drying room installed so that water can be drained outdoors. In winter, when the temperature drops below freezing at night, the jelly is frozen sufficiently during the night. During the day, the temperature rises again, so the frozen jelly will melt again and the water will drain. Repeated freeze thaw, after about a full filamentous dried product can be obtained.

You can get 200-250 g of real agar with 20% moisture from 1 kg of loot. 10 g of the silk agar was immersed in 500 g of water at 25 ° C. for 20 minutes, and the weight of the swollen silk agar was 50 g. This swelling does not feel the soft texture in the mouth, hard texture, but the manufacturing method of such a real agar has been produced only in winter in Korea in the past decades.

The silk agar prepared in this way is widely used in jelly, red bean jelly, malang jelly and so on. In addition, since the real agar is a fish product having a high fiber content, various applications have been developed. In particular, the seaweed salad, or agar noodles, soup for drying, such as the original use of the real agar and a lot of different parts are used. If the original characteristics of the real agar was a high sugar content, such as yokan, 갱 using a lot of sugar was an indispensable material. This is due to the sugar reactivity of only agar. This is because only agar can be concentrated.

However, since the silk agar made by the conventional method has a slow swelling rate in water, the texture in the mouth is not good when used as a food ingredient such as a seaweed salad.

That is, agar is a polysaccharide composed of agarose and agalopectin, cold water insoluble, has a linear and filamental structure, and above all, a macromolecular hydrophilic colloid material composed of galactose. Normally, it must be heated to 100 ° C to dissolve completely. The melting point is about 90 ℃, the gel point is about 35-43 ℃, a hard, transparent thermoreversible gel is formed at this point, the temperature of the melted gel to re-melt at 85 ℃ or more to re-dissolve Has characteristics. The real agar consisting of agarose and agalopectin alone absorbs water and swells much slower than other gums.

Therefore, the conventional silk agar has a poor texture in the mouth because it does not soften within a short time after absorbing the water when immersed in water. Therefore, when it is used for salad, completely different characteristics are required, and there is a need to improve the lacking part as the characteristics of the traditional real agar.

Accordingly, the present invention is to solve the problems as described above, by adding a gum dissolving solution consisting of a mixture of kappa-carrageenan, glucomannan, galactomannan and potassium chloride and wood starch extract as a substitute for salad agar substitutes It is an object of the present invention to provide a dried product of a real agar with a faster swelling speed in water than a real agar and a method for producing the same.

In addition, another object of the present invention is to provide a real dry cloth and a method for manufacturing the same, which can absorb water in a short time and feel a soft texture in the mouth.

In order to achieve the above object, the method of preparing a dry water-based fast-drying cloth according to a preferred embodiment of the present invention, kappa-carrageenan 40 to 60% by weight, glucomannan 30 to 50% by weight, galactomannan 0.5 to 5 Preparing a gum (GUM) solution obtained by dispersing 1 kg of the powder mixed at a ratio of weight% and 0.5 to 5 weight% of potassium chloride in 100 kg of purified water and then warming to 100 ° C .; Washing the dried wood starfish 5kg, extracted with 100kg of purified water for 2 hours at 100 ℃ and then put the perlite and filtered by filter press to prepare the wood starch extract; A mixing step of mixing the gum solution and the mantle starch extract and then mixing the same in a constant sealed container with a variable speed stirrer; A cooling step of pouring the mixed solution into a constant mold to leave the starch solids for 10 hours at a low temperature of 5 to 20 ° C. or lower; And a dried product forming step of cutting the solid wood solid matter into a noodle shape of 1 to 4 cm and then drying it in a drying plant to repeat freezing and thawing to obtain a dried product.

Preferably, the gum solution is a mixture of kappa-carrageenan: glucomannan: galactomannan: potassium chloride in a ratio of 5: 4: 0.5: 0.5.

And, preferably, the mixing ratio of the gum dissolving liquid and the mantle fern extract is 1: 9 to 9: 1.

On the other hand, the present invention is characterized by providing a dried product produced by the above production method.

The present invention is a water swelling as a result of experiments to determine the appropriate blending ratio for the commercially common kappa-carrageenan and glucomannan, galactomannan and potassium chloride in order to give a texture of the gel suitable as a substitute for the agar agar for salad This fast, moderate gel strength and toughness have been obtained and new texture is excellent in the mouth.

2 is a process chart related to a method for manufacturing a dry cloth in a yarn according to a preferred embodiment of the present invention. Referring to Figure 2 when explaining the manufacturing process of the fast-drying the real water swelling fabric prepared according to the present invention. The following weight percentages are relative to the total weight of the dry matter composition.

First step: manufacturing process of gum solution according to Japanese Patent Laid-Open No. 4-16153

As conventionally described in Japanese Patent Application Laid-Open No. 4-16153, "The thermoreversible gelling agent and its manufacturing method", as a method for producing a thermoreversible gelling agent for preparing foods having excellent solubility, taste, and gel transparency, 100% by weight of at least one type of carrageenan, such as κ-carrageenan, at least one type of glucomannan, such as purified pure kognac powder, and at least one type of galactomannan, such as purified locus bean gum. A method of preparing a gum solution is disclosed by mixing 10-80% by weight carrageenan, 10-80% by weight glucomannan, and 10-60% by weight galactomannan.

In the present invention, a gum solution is prepared using the above-mentioned thermoreversible gelling agent and its preparation, but first, potassium chloride is further added to kappa-carrageenan, glucomannan and galactomannan, and the mixture is stirred while heating an aqueous solution mixed with water.

First, carrageenan can be used in crude form (eg, washed seaweed) or in alkaline improved form or in commercially available conventional carrageenan extract. The carrageenan may be lambda, iota or kappa-carrageenan or in the form of a mixture thereof, but the preferred carrageenan species includes kappa-carrageenan. The concentration of kappa-carrageenan in the mixture is preferably 40 to 60% by weight.

Glucomannan can be used in purified or crude form. The crude form may be a ground of glucomannan untreated. Any glucomannan is suitable but preferred is Amorphophallus species, especially A. rivieri (Syn A. Konjac), Amorpopalus oncophyllus, Amorphopal A. variabilis, A. bulbifera and A. blumei caliber. The concentration of glucomannan in the mixture is preferably 30 to 50% by weight.

In addition to β-1,4-bonded mannose-units, galactomannan shows α-1,6-linked galactose-units at the same time and consists of mannose- and galactose components. Such galactomannans are obtained from commercially available guar gum, cassia gum and carob seed flour. The concentration of galactomannan in the mixture is preferably 0.5 to 5% by weight.

In addition, in the case of kappa-carrageenan as in the present invention, the gel strength can be effectively increased by adding potassium ions rather than the addition of sodium ions, which is called potassium-sensitive carrageenan. Therefore, potassium salts such as potassium chloride, potassium phosphate, potassium citrate, etc. may be used to increase the gel strength, but preferably potassium chloride. The concentration of potassium chloride in the mixture is preferably 0.5 to 5% by weight.

As such, the more preferred ratio of kappa-carrageenan to glucomannan versus galactomannan to potassium chloride, the gelling agent at the beginning of the heating process, is 5: 4: 0.5: 0.5, and the preferred concentration of the mixture bound to the aqueous phase is 0.5 to 5 Wt%, more preferably 1-2 wt%.
