Colorful food: from coloring to function Colorful food refers to "raw materials for food industry processed by physical methods from naturally colored food raw materials". It belongs to food ingredients, is a product colored by food, and belongs to the coloring scheme of clean labels. Different rich color foods have special color components, such as anthocyanins in elderberry and purple carrot, and beet glycosides in red beet, which can not only be used as rich color foods by standardizing their contents, but also have certain functional claims. French Diana Sambucus -- a natural solution to resist influenza and improve immunity. The edible history of Sambucus williamsii Elderberry is the fruit of elderberry. Elderberry, also known as black elderberry, belongs to the honeysuckle family and mainly grows in the Northern Hemisphere. Hungary and Austria in Europe are its main producing areas. There are also some plants in Heilongjiang, Jilin, Liaoning, Shanxi, Hebei and other regions in China. Elderberry has been used for hundreds of years in the West. As early as 400 BC, Hippocrates, an ancient Greek physician (respected by the West as the "father of medicine"), called Sambucus elderberry his "medicine box" because it can cure various diseases. Elderberry is a treasure all over the body. Its fruit, also known as Elderberry, is usually used as food (Elderberry wine and pie), as well as to treat colds and flu, activate the immune system, defecate and diuretic. Elderberry flowers, leaves and bark can also be used to relieve pain, reduce swelling, diuresis, defecate and induce vomiting. With the development of modern analytical methods, the chemical composition of Sambucus williamsii has been studied more and more clearly. Its effective components are mainly composed of anthocyanins, flavanols and vitamins. Anthocyanins: mainly cyanoside - 3 - glucoside, cyanoside - 3 - tribiotic glycoside, flavanol: mainly composed of quercetin and rutin. Vitamins: including natural vitamin C and vitamin A According to the data from the National Nutrition Database of the United States Department of Agriculture, the average content of anthocyanins in Sambucus williamsii is 485 mg/100 g. Average content of flavanol: 32,8mg/100g. Average content of natural vitamin C: 36mg/100g. Health efficacy and mechanism of Sambucus williamsii a) Antiviral and antibacterial We know that the mechanism of virus invasion into the human body is that it combines with the cell membrane through hemagglutinin, enters the cell, and then releases ceramidase, thus helping the virus enter the cell and spread. Research shows that the flavonoids in Sambucus williamsii, namely the flavanol we mentioned earlier, can inhibit the activity of hemagglutinin on the surface of the virus, prevent the release of ceramidase, so as to inhibit the virus from entering the cell and achieve the antiviral effect. In addition, experiments have shown that the flavonoids of Sambucus williamsii can combine in vitro and prevent the infection of influenza virus H1N1 type IV The standardized Sambucus williamsii can fight against a variety of bacteria and viruses that cause human upper respiratory tract infections. It has antibacterial activity and can kill 8 kinds of bacteria and 3 kinds of fungi b) Immunological activity of Sambucus williamsii Flavonoids and anthocyanins from Sambucus williamsii stimulate the immune system by promoting monocytes to produce proinflammatory cytokines. In a study on rats, it was found that the concentrated juice of Sambucus williamsii could effectively affect the transmission of influenza A virus and reduce the virus infection of rats. Another experiment is a study on 60 people with early flu symptoms. Through the self-evaluation of patients, it is shown that the flu symptoms of the patients taking elderberry group can be significantly improved after 3-4 days of treatment, while the placebo group takes 7-8 days. This shows that Sambucus Sambucus is effective in relieving flu symptoms. Antioxidant activity of Sambucus williamsii Through an in vivo experiment in rats, it was shown that compared with the control group, the resistance of the experimental group rats fed with cranberry for a long time to colitis was significantly enhanced, and the level of oxidative stress was relatively low. This is due to the role of anthocyanins in elderberry. Anthocyanins in elderberry can prevent oxidative stress caused by virus infection, thus helping to recover from infection. Other studies have shown that even the elderberry with low content of anthocyanins can effectively scavenge free radicals. Coloration of Sambucus williamsii Diana, France, provides two forms of natural elderberry products, concentrated juice and juice powder. The raw materials are from Central Europe. The anthocyanins of the two kinds of elderberry products were standardized, so as to standardize the color intensity. The pure natural process was used, without any added ingredients, including color and flavor. Diana's elderberry products are 100% pure natural products, with pleasant fruit flavor, natural color, and no pigment added, so they are especially suitable for children, especially in the flu season, and can be used to alleviate cold symptoms and stimulate immunity. In Europe, when used with acerola cherry, it can claim to maintain the normal function of the immune system and reduce fatigue. Application case: 1.
