Description

Composition for preventing discoloration of natural pigments {PREVENTIVE COMPOSITION OF COLOR CHANGE FOR NATURAL PIGMENT}

The present invention relates to a composition for preventing discoloration of natural pigments with excellent color preservation effect of natural pigments.

In general, pigments are substances added to add color to products. They can be natural or synthetic, and are used in various fields such as food, cosmetics, and clothing dyeing.

Synthetic pigments are artificially synthesized chemicals that exhibit excellent coloring and low discoloration rates and are inexpensive, so they have been widely used in place of natural pigments. Among these synthetic pigments, tar-based pigments such as Red No. 2, Red No. 40, Red No. 102, Yellow No. 4, and Yellow No. 5 can cause allergies and cause atopy or asthma, so the U.S. Food and Drug Administration (FDA) The FDA requires that cautions for use be indicated on products when tar-based colorants are added, and in particular, the use of Red No. 2 is prohibited. As concerns about the harmful effects of synthetic pigments, such as human toxicity and carcinogenicity, have continuously been raised, their use has been strictly regulated.

Along with the controversy over the safety of synthetic pigments, the use of natural pigments in various foods and cosmetics is increasing significantly due to health-oriented consumption trends.

Natural pigments are obtained from animals, plants, and microorganisms, and unlike synthetic pigments, they have the advantage of high safety and reliability. In addition, natural pigments have physiological activities such as bactericidal and anti-inflammatory properties, so they can be added to cosmetics and foods. However, natural pigments have a problem in that color fading and discoloration easily occur due to environmental factors during processing, storage, and storage, which reduces the marketability and sensory properties of the product. In addition, there are disadvantages in that the range of price and supply fluctuations is large depending on the limitations and types of coloring raw materials, and it is difficult to ensure uniformity and uniformity of color depending on the manufacturing process.

Existing chemical discoloration inhibitors such as PEG-n Dimethicone (n = integer from 1 to 20) and benzophenone, as well as plant-derived antioxidants such as vitamin C (ascorbic acid), quercetin, and enzyme-treated rutin, and natural substances such as betaine. Although discoloration inhibitors have been used, they do not effectively suppress discoloration of natural pigments and contain salt components, causing problems in product formulation.

Accordingly, much development and research is being conducted on discoloration inhibitors for natural pigments in order to maintain the color of natural pigments and apply them to various products.

For example, Republic of Korea Patent Publication No. 2015-0087600 uses a composition for preventing discoloration or discoloration of natural pigments containing acrylate/C10-30 alkyl acrylate crosspolymer and xanthan gum to improve the color stability of natural pigments and their usability in products. It is disclosed that it can be done.

In addition, Republic of Korea Patent Publication No. 2011-0054711 provides stability and prevention of discoloration through an anti-discoloration composition containing as active ingredients two or more selected from the group consisting of tea tree extract, Centella asiatica extract, and epigallocatechin gallate. We are showing that it can be done.

These patents have improved the stability of natural pigments to some extent, but the effect is not sufficient and their use is limited to specific color groups or the manufacturing process is difficult. Therefore, there is a greater need to develop an anti-discoloration composition that prevents discoloration of natural pigments through a simple process and can be easily applied to various products.

Amid this social awareness, the demand for products that minimize the content of chemical ingredients or replace them with natural substances is increasing.

Accordingly, when it comes to pigments added to give color to products, the use of natural pigments rather than synthetic pigments is increasing. However, natural pigments have complex chemical structures, and most of them have double bonds, so they are unstable and their structures are easily decomposed under the influence of pH, oxygen, moisture, heat, light, and metal ions, resulting in various colors such as fading, discoloration, or formation of new colors. Changes occur and have a negative impact on product quality.

For this purpose, in the prior art, chemical discoloration inhibitors and natural discoloration inhibitors were mixed together with natural pigments, but the stability of the pigments was not effectively improved, the form of applicable formulations was limited, and there was a problem of lowering formulation stability.

Experiment example 1. Color change evaluation

The oil-in-water emulsions prepared in Example 1 and Comparative Examples 1 to 7 were placed in a 15,000 Lux fluorescent lamp cabinet at 25°C, and measured with Hunter color at intervals of 1 day using a colorimeter (Spectrophotometer CM-3500D, Minolta, Japan). The L*, a*, b* values of the system were measured and the △E* ab value was obtained to compare the difference in color. The lower the △E* ab value, the smaller the color difference and the more stable it is. Generally, when it exceeds 3, discoloration can be recognized with the naked eye, so when it is 3 or less, stability is judged to be excellent. The results obtained at this time are shown in Table 2 below.

△E* ab 1 day 3 days Example 1 1.13 3.01 Example 2 2.25 3.00 Example 3 1.32 2.95 Comparative Example 1 2.49 9.92 Comparative Example 2 2.33 5.67 Comparative Example 3 2.10 4.78 Comparative Example 4 not measurable not measurable Comparative Example 5 2.48 6.50 Comparative Example 6 2.31 5.51 Comparative Example 7 2.50 3.43

In Table 2, it was confirmed that the examples according to the present invention exhibited superior light resistance and color stability compared to the comparative examples. Looking at the results on the first day, not only did the △E* ab of all comparative examples exceed 2 compared to the examples, but when measured on the 3rd day, the △E* ab value increased by more than 2 compared to the value on the 1st day, resulting in a very large color change. It was confirmed that this was the case.

Specifically, in the case of Comparative Example 1, which did not contain a composition for preventing natural pigment discoloration, the greatest change in color occurred on both the 1st and 3rd days, and in the case of Comparative Examples 2 to 4, which included only citric acid, there was a slight discoloration prevention effect on the 1st day. However, on the 3rd day, all discolorations visible to the naked eye appeared, and in Comparative Example 4, separation of the formulation occurred due to a decrease in pH as it contained a large amount of citric acid, making measurement impossible. Therefore, it was confirmed that sufficient discoloration prevention effect could not be obtained with citric acid alone. In addition, in Comparative Example 5, where acerola extract was used alone, a significant difference in color was observed for both 1 and 3 days, and in Comparative Examples 6 and 7, a mixture of citric acid and acerola extract was used, but the ratio was different, so there was no sufficient discoloration prevention effect. It was confirmed that it could not be obtained.
