Abstract

PURPOSE: To effectively extract a collagen component form the skin of swellfish. CONSTITUTION: A collagen component is extracted by boiling fresh skin of a swellfish in an aqueous solution containing alcohol such as SYOUTYUU (low-class distilled spirits) having deodorizing and sterilizing functions and concentrating the solution. The obtained collagen is boiled under stirring in water together with vegetable gelatin and a corrosion preventing agent such as granular potassium sorbate for preservation is added to the collagen solution while it is boiling. Powdery agar is added to the boiling collagen solution and the solution is continuously boiled to be concentrated. Subsequently, the concentrated solution is cooled to make it a semisolid state. An additive is added together with the corrosion preventing agent depending the use of the collagen, that is, a perfumery for cosmetic material and bathing agent, and a food additive for food.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing collagen obtained from puffer skin used as an adhesive for various kneading materials such as cosmetics, bath salts, confectionery, buildings and crafts.

[0002]

2. Description of the Related Art Conventionally, such collagen has been extracted from various plants or animals by chemical treatment.

However, since the skin of blowfish is made of a kind of protein, has a high amino acid index, and has a strong absorption ability, it is known as a nutritional material more than that of blowfish itself.
It has components such as unsaturated fatty acid EFA, eicosaexapentaenoic acid, and PHA tocosaexaenoic acid, and its collagenous material can be used for various purposes.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for efficiently extracting collagen from blowfish skin.

[0005]

The present invention is a method for extracting collagen from fugu skin, which comprises the following steps.

That is, the skin of live blowfish is boiled down in an alcohol-containing aqueous solution having a deodorizing and sterilizing function like shochu in a boiling state to extract collagen, and the obtained collagen is stirred in water with vegetable gelatin. While boiling, administer a corrosion inhibitor for preservation such as granular potassium sorbate, add powdered agar to this boiling collagen solution, continue to boil and boil, then cool. Make a semi-solid state.

[0007] Cosmetics, fragrances for bath salts, and additives for foods are selectively blended together with the corrosion inhibitor depending on the use as collagen.

[0008]

[Function] Collagen is boiled and extracted by combining deodorization and sterilization such as shochu of live blowfish skin, and after corrosion prevention treatment for preservation, it is cooled with vegetable gelatin such as agar to produce collagen in the latter half solid state after cooling. To do.

[0009]

[Example] 1 kg of natural tiger blowfish skin was mixed with 2 parts of alcohol.
The boiling state was boiled down for 30 minutes while boiling 720 cc of 0 ° C distilled water in an aqueous solution of shochu diluted with 1440 cc of water to boil down to obtain condensed collagen. The total amount of this collagen was put into 1000 cc of water, to which 30 g of granular potassium sorbate was added, and the mixture was boiled while stirring well.
With this boiled down, 500 cc of water and 4 g of powdered agar were added and boiled for 30 minutes to boil down. By leaving it at room temperature, it is a semi-solid fair white,
A translucent collagen was obtained which had a good luster and yet was well spreadable.

[0010]

According to the present invention, the following effects can be obtained.

(1) It is possible to easily obtain high-quality collagen which has a good tenacity and can be stored at room temperature from the puffer skin which has been conventionally provided only for food.

(2) The obtained collagen is comparable to the high-quality collagen among conventional collagens, and can be suitably used as a collagen for cosmetics.
