DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-fading agent and a method for preventing fading of natural pigments in foods and drinks, pharmaceuticals, quasi-drugs, feed and cosmetics.

[0002]

2. Description of the Related Art Foods and drinks, such as juices, vegetables, fish and shellfish, livestock meat and processed products thereof, include natural pigments, especially carotenoid pigments (eg, β-carotene, astaxanthin, etc.), anthocyanin pigments, heme pigments and the like. In addition, these natural pigments are used in pharmaceuticals, quasi-drugs, feeds, and cosmetics for the purpose of appealing to consumers' sight and increasing the commercial value or as a nutrient. However, these dyes are oxidized in light or air during storage and rapidly fade. For this reason, vitamin C (L-ascorbic acid) has been mainly used as an anti-fading agent, and vitamin E (α-tocopherol) and rutin have been used.

[0003]

However, the effect of L-ascorbic acid cannot be said to be sufficient,
Since tocopherol and rutin are hardly soluble in water, use of water-soluble products is naturally restricted. For this reason, there has been a strong demand for the development of a water-soluble and effective anti-fading agent and a method for preventing the fading.

[0004]

In view of the above circumstances, the present inventors diligently study a water-soluble anti-fading agent which is highly safe, has a stronger effect than L-ascorbic acid, and is water-soluble. Performed, the anti-fading agent consisting of water or hydroalcoholic extract from sunflower seeds or its oil cake and L-ascorbic acid or salts thereof has a much better anti-fading effect than using each alone. And completed the present invention.

[0005]

In other words, the present invention provides a discoloration inhibitor comprising a component extracted from sunflower seeds or its oil cake and extracted with water or hydroalcohol, and L-ascorbic acid or salts thereof; A method for preventing fading, comprising allowing a component extracted with water or hydroalcoholic water from sunflower seeds or its oil cake to coexist with L-ascorbic acid or a salt thereof in a pharmaceutical product, a quasi-drug, a feed or a cosmetic. Is provided.

Hereinafter, the present invention will be described in detail. The sunflower seeds used as a raw material of the anti-fading agent used in the present invention are sunflowers belonging to the family Asteraceae and the genus Sunflower “Japanese name;
Sunflower, Scientific name: Helianthus News
nthus annuus L .; )), Which is mainly used as a raw material for sunflower oil and as feed for pets. In addition, the grain after oiling is usually used as feed for livestock, and this is also a suitable raw material of the present invention. Of course, hexane after oiling,
Needless to say, other solvents from which the fat component has been removed can also be used as the raw material of the present invention.

In order to obtain the sunflower seed extract as referred to in the present invention, sunflower seeds are crushed to an appropriate size using a crusher or the like. If the shell has already been crushed with oiled cake or the like, it may be used as it is. To this, about 5 to 10 times the amount of water or hydrous alcohol is added, and extraction with water is performed by heating to 50 to 100 ° C. or using an autoclave (120 ° C. × 1 atm). When using hydroalcoholic alcohol, a 20-80% alcohol solution,
Preferably, a 30 to 65% alcohol solution is used, and room temperature to
It is extracted by heating and extracting at 70 ° C., preferably around 50 ° C.

As the alcohol, methanol, ethanol, propyl alcohol, isopropyl alcohol and the like can be used. The extract may be concentrated under reduced pressure and dried to be powdered, or may be obtained as a paste or a hydroalcoholic solution. The anti-fading agent of the present invention comprises the sunflower seed extract thus obtained and L-ascorbic acid or a salt thereof as main components. Ascorbate is a physiologically-used physiological food usually used for pharmaceutical foods. For example, sodium salts which are acceptable are used, such as sodium ascorbate and calcium ascorbate.

[0009] Other antioxidants conventionally used may be added to these together, and at least one selected from organic acids and inorganic acids and salts thereof, particularly alkali metal salts, is used in combination. It is also possible to further stabilize and enhance the effect by making it exist.
Further, by adding a polysaccharide, an oligosaccharide or other saccharides, the spreadability of the anti-fading agent can be enhanced. Examples of organic acids and inorganic acids used as food additives include citric acid, DL-malic acid, phosphoric acid, polyphosphoric acid, hexametaphosphoric acid, and the like, and examples of the alkali metal salts thereof include trisodium citrate, Sodium malate,
Disodium hydrogen phosphate, sodium dihydrogen phosphate, sodium polyphosphate, sodium hexametaphosphate and the like are used.

Examples of the saccharide include curdlan, xanthan gum, carrageenan, guar gum, polydextrose, lactose, dextrin, glucose and the like. The weight composition ratio of the sunflower seed extract and the L-ascorbic acid or salts thereof in the anti-fading agent according to the present invention,
The ratio is 1: 0.5 to 10, more preferably 1 to 5.

[0011] The anti-fading agent according to the present invention may be a natural pigment itself or a food and beverage, a pharmaceutical, a quasi-drug containing the same,
Used in addition to feed or cosmetics. For example, in the case of foods and drinks, juices, jellies, Japanese confectionery, western confectionery, fish paste products, raw fish, red fish, dried fish, koji pickles, bottling etc., ham, sausage, other processed meat products, dried vegetables, vegetables Add to processed products, soups, sauces, etc. to prevent fading of pigments on sugar-coated tablets, vitamin-derived pigments such as drinks and other natural pigments in the case of pharmaceuticals, and kneading in the case of quasi-drugs It is used to prevent fading of pigments such as toothpaste, shampoo and bar soap.

In the case of feed, β is used for the purpose of fried red fish.
-Carotene and astaxanthin are added,
The decomposition of these pigments not only lowers nutritional aspects but also changes the appearance, and can be used for the purpose of preventing this. In the case of cosmetics, they are added to natural lotions, cosmetic creams, foundations and the like, and are used to prevent deterioration due to decomposition of existing pigments. The amount of the anti-fading agent according to the present invention is usually 0.005 to 1% by weight,
Preferably it is 0.01 to 0.5% by weight.

[0013]

Industrial Applicability The anti-fading agent of the present invention and the anti-fading method using the same comprise an extract obtained from a sunflower seed which is a natural product and L-ascorbic acid (vitamin C) which is a natural product. Because it ’s safe,
Further, a far higher fading prevention effect can be obtained than when each of them is used alone.
