3.2  Active ingredients of  Bilberry Extract Powder

Anthocyanins are a general term for a class of substances formed by combining anthocyanins and sugars. Anthocyanins are polyhydroxy and methyl derivatives of 2-phenylbenzopyran cations. Due to the presence of conjugated double bonds, anthocyanins can absorb visible light and present certain colors. Anthocyanins have maximum light absorption in the wavelength range of 465-560nm and 270-280nm respectively. The R1 and R2 groups on the 3- and 5-carbon positions of the B-ring are mainly -H, -OH and OCH3, and the different substituents determine flowering The type and color of the pigment.

3.3 Benefits and Application of Red bean bilberry extract 

1). Antibacterial effect

2). Antiviral effect of Red bean bilberry extract powder
Bilberry total flavonoids can significantly reduce the mortality of mice challenged with influenza virus A1; significantly prolong the disease incubation period and survival time of mice infected with influenza virus A1.

3). Anticancer effect
Bilberry fruit ethyl acetate extract can induce the production of quinone reductase (QR). Its crude extract can obviously inhibit the activity of ornithine-releasing enzyme and fight cancer.

4). The 5% alcohol extract of the whole plant has a resistance hormone effect on male frogs; the infusion or decoction of the leaves has a diuretic effect.

3.4 Application of Red bean bilberry extract

1)

Red bean bilberry extract is a food colorant with good color quality and wide color gamut. It can show different colors in acidic and weakly alkaline environments. It can be added to different styles of food, and the United Nations FAO/WHO joint food According to the existing toxicological data, the Expert Committee on Additives believes that anthocyanins are "extremely toxic", and have listed them as natural pigment food additives (E163). Anthocyanins extracts (including Red bean bilberry extracts) are also listed by the US FDA As a food additive without certification, it is allowed to be used in beverages, dairy products and pastries.

2). Application to functional food industry

Unregulated oxidation and free radical attack are one of the fundamental causes of human aging and disease, and many phenolic hydroxyl groups contained in anthocyanin molecules strongly resist the uncontrolled oxidation and free radical attack in the body and reduce or inhibit the human body. Red bean bilberry extract can be used as a functional ingredient for functional foods and can be used as a nutritional supplement. In addition, anthocyanins have the effect of improving night vision, that is, night vision. Matsumoto et al. Demonstrated that anthocyanins were able to pass through the atrioventricular barrier for study and enter into the ocular tissues of rats and rabbits, regardless of oral administration, intraperitoneal injection or intravenous injection. Oral administration of cassis extract, which is rich in cy-3-g (cyanobacterine-3-o-glucoside, which is the most important ingredient of bilberry anthocyanins), can improve blackish caused by prolonged exposure to the display terminal. Anthocyanins have the function of activating the resynthesis system of rhodopsin, and it is assumed that there is a function to improve the sight. Foreign health product manufacturers often combine anthocyanins and lutein and claim to have a full effect on improving eyesight. For example, American newnordic's blueberry Eyebright dietary supplement prescriptions include Red bean bilberry extract, grape seed extract, calendula extract, lutein in Europe. With so many active functions, the broad use of Red bean bilberry extract in the functional food industry is taken as a matter of course.

3). Application to pharmaceutical industry

Many experiments have now shown that anthocyanins have antioxidant effects on mammalian cells, induce apoptosis in cancer cells, inhibit their proliferation, and inhibit inflammatory responses. Anthocyanin is highly soluble in water, but it is confirmed that anthocyanins are present in cells, and anthocyanins are absorbed in cells through cell membranes. In Europe, Red bean bilberry extract with an anthocyanin content of more than 24% is used as a drug, and the extract of European bilberry anthocyanins (miltcycyan) is recorded in Italy, Germany, and other countries. The purity requirements for pharmaceuticals are generally high, making it difficult to reach the international standard of anthocyanin content in simple extraction and purification processes, which are bottlenecks that limit the industry of Red bean bilberry extract in my country urgent improvement is necessary, for example, exported to foreign countries with a low added value.
