Food coloring, also known as food coloring agent, is an edible substance that makes food color, thereby improving the hue and luster of food. Before the 10th century, the ancients began to use plant-based natural pigments to color food. Food colorings are divided into synthetic food colorings and natural food colorings. Synthetic food colorings include carmine and lemon yellow, and natural food colorings include curcumin and carotene. Food coloring is pleasing to the eyes and stimulates people's appetite, but it may also harm people's health.

my country restricts the use of synthetic pigments

my country also has strict restrictions on the addition of synthetic pigments to food: all meat and its processed products, fish and its processed products, vinegar, soy sauce, fermented bean curd and other condiments, fruits and their products, milk and dairy products, baby food , Biscuits and cakes can not use synthetic coloring. Only soft drinks, cold foods, sweets, mixed wines and sherbet can be used in small amounts, generally not exceeding 1/10000.

Natural colouring

At present, there are 6 varieties of food synthetic pigments approved for use in my country, namely, amaranth, carmine, lemon yellow, sunset yellow, indigo and brilliant blue. Although the harm of these 6 kinds of edible synthetic pigments is still inconclusive, they do not have any nutritional value and are not helpful to human health. If you can, try not to eat them.

In fact, driven by huge economic interests, the phenomenon of over-standard and over-range use of synthetic pigments in food in our country has been repeatedly prohibited. You must be careful when buying food and not excessively pursue the color of the food.

As we all know, food safety issues have long been the focus of heated discussions among consumers. People want what they eat is safe and healthy. This change in consumption concepts and the country's increasingly stricter standards for the food industry have caused manufacturers in the food industry to transition from synthetic pigments to natural pigments. However, many manufacturers do not know much about natural pigments because they are new to them.

Carotene can replace synthetic pigments lemon yellow and sunset yellow

For example, I often hear customers ask us if they used synthetic pigments before, whether there are any natural pigments that can be directly replaced. This can ensure that the color of the product remains unchanged, but also meets the national food standards, and consumers are also easy to accept and recognize.

Carotene manufacturers

In fact, many natural pigments can directly replace synthetic pigments. Today I will talk about the sunset yellow and lemon yellow that are used in synthetic pigments. What can it be replaced by natural pigments?

Hebei Yuhua Biotechnology Co., Ltd. has two colors of β-carotene, one is golden yellow and the other is orange yellow. The technical research and development team of Hebei Yuhua Biotechnology Co., Ltd., after understanding that many customers need to replace the natural pigments of sunset yellow and lemon yellow, developed golden yellow beta carotene instead of sunset yellow and orange carotene instead of lemon yellow.

So now friends from manufacturers who are still using these two synthetic pigments, might as well use beta carotene instead.

Use note:

1. When used in food coloring, you can dilute the natural food coloring by 5-10 times with water or oil, and then mix with the material to be more uniform; when used for skin coloring, you can properly dilute the natural food coloring by 10-100 times and then soak or Spray. Natural pigment manufacturers

2. Natural food coloring at a suitable concentration (about 0.1-0.2%) will show a beautiful color, ▲but when the natural food coloring is excessive, it will appear dark, so a small amount should be added gradually during the application process to achieve good Effect.

3. Natural food pigments are easily affected by metal ions such as copper and iron to change color. Therefore, in the process of food processing, stainless steel utensils and deionized water are preferred to improve the stability of the pigments. ▲Foods with high protein content also absorb part of natural pigments.

4. Natural food pigments are easily faded under the influence of high temperature and sunlight for a long time, so the coloring process should be arranged in the post-production process as much as possible, and the finished or semi-finished products after the coloring should be stored at low temperature and avoid light.

5. Natural food coloring is non-irritating, but some products have strong coloring power, and it is not easy to wash off immediately after sticking to the skin, but there is no need to worry, it will disappear after two or three days. Wear long clothes to cover the bare skin during operation.

6. Natural edible coloring is a natural extract, in line with China's food hygiene regulations, non-toxic, and can be used in food coloring, but it is not suitable for direct human consumption.

▲Why does natural food coloring fade?

Natural food coloring is affected by certain factors, such as high temperature, light, overacid and overalkali, oxygen, metal ions and so on.

① Material density influence: steel balls, cast iron balls, alloy steel balls, etc. Different materials have different densities. The density of valve stainless steel ball steel is higher than that of cast iron, while alloy steel varies according to the density and content of the main alloy elements.

②The influence of the steel ball manufacturing method: the rolled and forged steel balls have a dense structure, so the density is high, and the structure of the cast steel ball, cast iron ball or cast alloy ball is not very dense, and even has pores, so the density is low some.

③The influence of steel ball metallographic structure: bearing stainless steel ball martensite, austenite, bainite, ferrite and other different crystal structures have different densities, which also have an impact on crystal fineness.

④The influence of chemical composition elements: the different chemical composition contained in the finished steel ball, such as iron, carbon, chromium, manganese, sulfur, phosphorus, etc., will affect the hardness and impact wear of the steel ball to varying degrees. Generally speaking, If the chromium content is large, the steel ball has high wear resistance.
