ある。Among pigments, anthraquinones and carotenoids are found in many resources in animals and plants, and are easy to obtain, have extremely low toxicity, have good color development, and are easy to use. Although it is often used in industrial applications or in food products, it is exposed to sunlight. Discoloration tends to occur over time due to oxidation, etc., and the color tone becomes unstable. Many methods are known for preventing the destabilization of these dyes, but each method has the disadvantage that the degree of prevention is low.
この発明はこのような欠点のないものである。The present invention is free from such drawbacks.
この発明を以下に説明する。この発明の適用色素は、ア
ントラキノン系及びカロチノイド系のもの一般である。This invention will be explained below. The pigments applicable to this invention are generally anthraquinone and carotenoid pigments.
両者の均質な混合物についても適用することができる。
アントラキノン系色素としては、カルミン酸、ラツカイ
ン酸、ケルメシン酸等が代表例としてあげられる。It can also be applied to a homogeneous mixture of both.
Representative examples of anthraquinone dyes include carminic acid, latcaic acid, and kermesic acid.
カロチノイド系色素としては、β一カロチン、ビキシン
、ノルビキシン、カプサンチン、クロチン、ルテイン、
β−アポカロチナール、カッタキサンチン等が代表例と
してあげられる。Carotenoid pigments include β-carotene, bixin, norbixin, capsanthin, crotin, lutein,
Representative examples include β-apocarotenal and cattaxanthin.
この発明は、これらの色素に対して、安定化するための
組成物を使用する。This invention uses stabilizing compositions for these dyes.
その組成は、次の通りである。酒石酸ナトリウムとミヨ
ウバンと炭酸ナトリウムとの配合物である。Its composition is as follows. It is a combination of sodium tartrate, alum and sodium carbonate.
酒石酸ナトリウムは１０〜４５％（重量、以下同じ）、

~50 parts (same weight and below), while the latter is 10 to 50 parts
Department. The blend system should be homogeneous. At this time, the purpose is best achieved if the system is neutral. Therefore, sodium tartrate, alum, and sodium carbonate do not need to be added simultaneously, and may be added separately. When the system is acidic or alkaline, add a pH adjuster that does not adversely affect the quality of the dye and stabilizing composition, such as a dilute aqueous mineral acid solution or a dilute aqueous sodium hydroxide solution.
It is preferable to make the system slightly acidic or slightly alkaline.
The system here represents a homogeneous water-soluble system. This product is added to the surface or inside of desired foods, such as sugar, processed seafood products such as kamaboko, baked goods, and other objects.
添加する方法は、次に記す３つの態様の何れでもよい。
その１は、相手の色素にこの安定化のための組成物を添
加混合する方法である定その２は、先ず着色を要する物
、例えば、かまぼこを色素で着色してから、これにこの
安定化のための組成物の水溶液を噴霧し、あるいはその
水溶液中にかまぼこを浸漬する方法である。The method of addition may be any of the following three modes.
The first method is to add and mix this stabilizing composition to the other dye.The second method is to first color an object that requires coloring, for example, a kamaboko, with a dye, and then add this stabilizing composition to the dye. This is a method of spraying an aqueous solution of the composition or immersing the kamaboko in the aqueous solution.
その３は、かまぼこを予めこの安定化のための組成物で
処理（例えば、その水溶液中に浸漬する、あるいは組成

This is a method of coloring using
