Abstract

PURPOSE:To stabilize a carotenoid dyestuff in a readily decomposable paprika extract over long period of time by hermetically sealing the paprika extract together with a disoxidizer in an oxygen-impermeable packaging material. CONSTITUTION:This method for stabilizing a carotenoid dyestuff in a paprika extract is to hermetically seal a paprika extract together with a disoxidizer (preferably a material prepared by filling a granular readily oxidizable substance such as active iron oxide or ascorbic acid in a small bag using paper or a plastic as a substrate or processing the substance into a sheetlike form) in an oxygen-impermeable packaging material (preferably a plastic film having <=100ml/24hr.m<2> oxygen permeation coefficient, e.g. vinylidene chloride-coated stretched PP/unstretched PP).

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to the stabilization of carotenoid pigments in paprika extracts used to improve the color tone of egg yolks such as chickens.

[0002]

2. Description of the Related Art Conventionally, in order to improve the color tone of egg yolk such as chicken, it has been practiced to incorporate a color tone improving agent into feed. As color tone improvers, paprika, spirulina, marigold are known as natural products, and canthaxanthin and β-apo-8'-carotate ethyl ester are known as synthetic products, but they are consumer-oriented and safety-oriented. Therefore, paprika, which is a natural product, is currently used mainly as a color improving agent for chicken egg yolk.

Paprika is a plant of the Solanaceae family that prefers a Mediterranean climate and is cultivated in many countries such as the United States, Spain, Hungary, Morocco and China. Paprika contains a large amount of red-colored carotenoid pigment containing capsanthin as a main component, and when this is fed to chickens, the carotenoid pigment contained therein improves the egg yolk of chickens. For this purpose, a so-called paprika extract (paprika oleoresin) obtained by crushing dried paprika and extracting a carotenoid pigment as an active ingredient with an organic solvent such as hexane is usually used.

However, it is known that the carotenoid pigment in the paprika extract is rather unstable, and the carotenoid pigment content in the extract gradually decreases. To prevent this, for example, ethoxyquin, butyl hydroxytoluene (BHT), butyl hydroxyanisole (B
It is known to mix additives such as HA), tocopherol, and ascorbic acid, but the effect is not sufficient.

DISCLOSURE OF THE INVENTION The present invention provides a method for stabilizing carotenoid pigments in a paprika extract which is easily decomposed.

[0006]

[Means for Solving the Problems] The inventors of the present invention have conducted extensive studies to solve the above-mentioned problems. As a result, most of the decomposition of carotenoid pigments in paprika extract is due to oxidation, and paprika extract It was found that the carotenoid pigment in the paprika extract can be stabilized for a long period of time without being decomposed by encapsulating it in an oxygen-impermeable packaging material together with an oxygen scavenger, and completed the present invention.

That is, the present invention relates to a method for suppressing and stabilizing the decomposition of carotenoid pigment in a paprika extract, and specifically, the paprika extract and an oxygen-impermeable packaging material together with an oxygen scavenger. It is characterized by being sealed inside. The means for sealing may be any method as long as oxygen in the outside air does not substantially enter the packaging container, but usually the object can be easily achieved by heating and pressing a plastic film described below. it can. At this time, it is preferable to deaerate or replace the inside of the packaging material with nitrogen beforehand, because the carotenoid pigment in the paprika extract can be stabilized with a smaller amount of oxygen scavenger.
Further, after sealing, it may be stored at room temperature and need not be frozen or refrigerated.

The paprika extract referred to in the present invention is obtained by drying paprika fruit which is a plant of the Solanaceae family, pulverizing and pelletizing it, and then extracting a fat-soluble component containing a carotenoid pigment with an organic solvent such as hexane, The organic solvent is removed, and natural products such as wheat flour, defatted rice bran,
Also included are so-called premixes in which feed ingredients such as minerals and vitamins are mixed and the concentration of carotenoid pigment is adjusted, and further, paprika extract-containing feed prepared so that they can be fed directly to chickens and the like.

The oxygen scavenger used in the present invention may be any one as long as it can chemically react to remove oxygen in the air, but a granular oxidizable substance (for example, active iron oxide or ascorbine) can be used. An oxygen scavenger of a type in which a small bag of paper or plastic is filled with acid, catechol, or the like, or a type processed into a sheet is suitable. Such oxygen absorbers are widely used mainly in the food field, and there are many commercial products. For example, Ageless (trade name, manufactured by Mitsubishi Gas Chemical Co., Inc.), Secure (trade name,
Nippon Soda Co., Ltd.), Vitalon (trade name, manufactured by Toagosei Kagaku Kogyo Co., Ltd.), etc., and many types are produced depending on the oxygen absorption etc., but depending on the type and capacity of the packaging container used It may be selected appropriately.

The packaging material used in the present invention may be any as long as it can substantially block oxygen, such as metal, glass,
Although plastic or the like can be used, a plastic film can be preferably used in terms of its lightness, easy handling, and the like. Any plastic film may be used as long as it has an oxygen permeability coefficient of 100 (ml / 24 hr · m ² ) or less. Specifically, vinylidene chloride-coated stretched polypropylene / unstretched polypropylene, vinylidene chloride-coated cellophane / low density polyethylene. , Vinylidene chloride coated nylon / low density polyethylene, vinylidene chloride coated polyester / unstretched polypropylene, biaxially oriented polypropylene / ethylene / vinyl alcohol copolymer / low density polyethylene, polypropylene / vinylidene chloride / polypropylene, polyester aluminum deposition / low density polyethylene And so on. Among these, aluminum vapor-deposited ones and aluminum foil-coated ones are more preferable because they can block light.

Hereinafter, the present invention will be described in more detail with reference to examples.
