Color rich food from coloring to function

Rich color food refers to "raw materials for food industry produced by physical processing from naturally colored food". It belongs to food ingredients, a product colored by food, and a coloring scheme for clean labels. Because of their special color components, such as anthocyanins in elderberries and Purple Carrots, and anthocyanins in red beets, different color rich foods can not only be used as color rich foods by standardizing their content, but also have certain functional claims.

Edible history of elderberry

Elderberry is the fruit of elderberry. Elderberry, also known as black ancient wood, belongs to the honeysuckle family. It mainly grows in the northern hemisphere. Hungary and Austria in Europe are its main production areas. Heilongjiang, Jilin, Liaoning, Shanxi, Hebei and other regions in China also have some planting.

Elderberries have been used in the West for hundreds of years. As early as 400 years before the park, Hippocrates, an ancient Greek doctor, called elderberry his "medicine box" because he could cure various diseases.

Elderberry is full of treasure. Its fruit, elderberry, is usually used as food, as well as for colds and flu, activating the immune system, defecation and diuretics. Elderberry flowers, leaves and bark are also used to relieve pain, detumescence, diuresis, defecation and induce vomiting.

As modern analytical methods become more and more advanced, the chemical composition of elderberry has also been studied more and more clearly. Its effective components are mainly composed of anthocyanins, flavanols and vitamins. Anthocyanins: mainly cyanoside-3-glucoside and cyanoside-3-abioside. Flavanol: mainly composed of quercetin and rutin. Vitamins: including natural vitamin C and vitamin A. according to the data of the national nutrition database of the United States Department of agriculture, the average anthocyanin content of elderberry is 485mg/100g. The average content of flavanol is 328mg/100g

Health effects of elderberry

We know that the mechanism of virus invasion into human body is to enter cells through the combination of hemagglutinin and cell membrane, and then release ceramide enzyme, so as to help the virus enter cells and spread.

Studies have shown that the flavone component in elderberry, the flavanol we mentioned earlier, can inhibit the activity of hemagglutinin on the surface of the virus and prevent the release of ceramide enzyme, so as to inhibit the virus from entering cells and achieve the antiviral effect.

Experiments also showed that the flavonoids of elderberry can combine in vitro and prevent the infection of influenza virus. The standardized elderberry can resist a variety of bacteria and viruses that cause human upper respiratory tract infection. It has antibacterial activity and can kill 8 kinds of bacteria and fungi.

Antioxidant activity of elderberry

An in vivo experiment in rats showed that compared with the control group, the experimental group with long-term consumption of elderberry significantly increased its resistance to colitis, and its level of oxidative stress was relatively low. This is due to the role of anthocyanins in elderberry, which can prevent oxidative stress of virus infection and help recover from infection. Other studies have shown that even using elderberries with low anthocyanins can effectively eliminate free radicals.
