Because the colors on the cake cream are all pigments, it must be very difficult to clean. It is recommended to apply baking soda and detergent to the colored ones before washing, and then soak them for one night.
Pigment is a raw material that gives a certain color. People often choose goods by feeling such as sight, touch and smell, and pigment is an important part of vision, so whether pigment is used properly also plays a decisive role in the quality of products.
synthetic pigments food pigments are called synthetic pigments. Inorganic pigments commonly used inorganic pigments include iron oxide, carbon black, chromium oxide green, etc. They have good light resistance and are insoluble in water. Natural pigments commonly used include cochineal, cochineal, chlorophyll, curcumin and lycopene.
Make food more attractive:
Many natural foods have their own colors, which can promote people's appetite and increase the secretion of digestive juice, thus facilitating digestion and absorption, and are important sensory indicators of food. However, natural food is easy to fade or change color during processing and preservation. In order to improve the color of food, people often add food pigments in the process of processing food to improve sensory properties.
It is not a patent for modern people to add pigment to food. In fact, in ancient China, people knew that red wine was made from monascus pigment. Since Parkin, an Englishman, synthesized the first artificial pigment, aniline violet, in 1856, the synthetic pigment also appeared on the stage and played a role in improving the color of food.
There are two kinds of food pigments commonly used now: natural pigments and synthetic pigments. Natural pigments come from natural materials, mainly extracted from plant tissues, and also include some pigments from animals and microorganisms. Synthetic pigment refers to organic pigment prepared by artificial chemical synthesis, which is mainly made from aniline dye separated from coal tar.
for a long time, because people didn't realize the harm of synthetic pigments, and compared with natural pigments, synthetic pigments have the advantages of bright color, strong coloring power, stable properties and low price, etc., many countries generally use synthetic pigments in food processing industry.
