In 2011, researchers from the Institute of Desertification of the Chinese Academy of Forestry saw a large area of wild black wolfberries for the first time in Delinghatosu Lake, and happily said that the medicinal value of black wolfberries is very high, and the market price is much higher than that of ordinary wolfberries. After that, the news that qinghai wild black wolfberries were stolen by thousands of people attracted the attention of people in many industries, and the popularity of black wolfberries was because of the "magical ingredient" behind it - anthocyanins.
Six or seven years have passed, and the current artificial cultivation of black goji berries has been successful, and this artificially grown black goji berries are no different from the wild black goji berries. Scientific research has proved that the antioxidant "holy product" contained in the fruit of black goji berries - anthocyanins (i.e., anthocyanins), its content is much higher than that of blueberries known as the "king of berries".
Nature's magician - anthocyanins
Anthocyanins are a class of water-soluble pigments widely found in plants that absorb different wavelengths of sunlight and make plants appear colorful.
This change is mainly determined by the pH number in the environment. Usually, it will appear red in the acidic environment, pink, purple in neutral, blue and green in the weak alkaline environment, and yellowish green and yellow in the strong alkaline environment. So the higher the anthocyanin content, the darker the color of the plant!
Of course, anthocyanins are not only found in black goji berries. In our daily life, many purple, black, and blue foods generally contain anthocyanins.
【Domestic Research】
Black goji berry anthocyanin has the effect of scavenging free radicals, antioxidants, anti-aging, lowering blood lipids, eye protection, etc., not only protecting vision and improving sleep, but also effectively preventing and treating diabetes, tumor cancer, blood clots and other diseases, helping to reduce blood pressure and protect the heart and brain and other functions.

Anthocyanins can increase the secretion of tear fluid, relieve eye fatigue, and have a preventive and protective effect in a variety of ophthalmic diseases.
--Yao Jiayu and Li Zhijian, author of the International Journal of Ophthalmology, "Research Progress of Blueberry Anthocyanins in Ophthalmic Diseases"
Researcher Yang Yang used the cell counting kit-8 (cck-8) method to screen the anti-tumor activity of anthocyanins and found that high-purity anthocyanins can inhibit tumor cell proliferation very well. And the high-purity anthocyanin acts on hepg2 liver cancer cells, so that the anthocyanin dosage (ic50) value when it dies half is 223 mg/ml, the ic50 value of breast cancer cells is 112.56 mg/ml, and the ic50 value of raw264.7 macrophages is 26.32 mg/ml. It can be seen that anthocyanins have a good anti-cancer effect.

【Foreign Studies】
"e-health net", a lifestyle disease prevention website provided by the Japanese Ministry of Health, Labor and Welfare, points out that the anthocyanins rich in vegetables and fruits such as blueberries have a strong antioxidant effect and are expected to help remove reactive oxygen species from the body, so it may help prevent arteriosclerosis, aging, cancer and other problems.
Studies conducted by institutions such as the University of East Anglia (UEA) in the United Kingdom have found that ingesting anthocyanins through fruits and vegetables may help improve insulin resistance, lower blood sugar, and may also inhibit inflammation.
1 In 2016, the Seventh Research and Development Framework Programme (fp7) of the European Union provided 3 million euros for this purpose, with a total investment of 4.3 million euros in research and development, funding the formation of a European athena research and development team in six EU member states of the United Kingdom, France, Germany, Italy, the Netherlands and Turkey, and for the first time established a relatively systematic and complete anthocyanin content information database for different food varieties in the world, providing scientific guidance for human healthy diet. The R&D team once again confirmed in phase III clinical trial studies of phytoanthocyanidin epidemiology and intestinal microbiome that anthocyanins help reduce the risk of heart disease, cardiovascular and other diseases, and can also effectively resist tissue radiation damage during chemotherapy and radiotherapy for some cancers.
A number of domestic and foreign studies have confirmed that anthocyanins do have hypolipidemic and antioxidant effects, and it can react with free radicals that cause aging in the human body, thereby reducing and scavenging free radicals in the body and achieving the effect of delaying aging.
Use anthocyanins - create a noble black miracle
The extraction technology of improving the stability of anthocyanins through artificial acylation can extract and isolate anthocyanin pigments from the tissues of grapes, blood oranges, blueberries, eggplant peels, mulberries, hawthorn skins, perilla, purple sweet potatoes, etc., such as blackcurrant red, natural amaranth red, purple corn pigment, mulberry red pigment, perilla pigment, etc.
As a natural food color, anthocyanins are safe and non-toxic, have certain nutritional and pharmacological effects, and have great application potential in food, makeup, medicine and other aspects.
--In Zhao Yuying's "Research Status and Development Trend of Anthocyanins"
The main ingredient of perilla pigment is perilla, purple suning, is present in the perilla family with purple leaves of the variety of natural red pigment, Japan in 1993 on its provisions as a food additive, and used in chewing gum, juice drinks, etc., is believed to have the effect of preventing allergies, anti-caries, anti-inflammatory and so on.
In the 1980s, Japan extracted four anthocyanins from the leaves of red cabbage and used them as food colorants (red to red and purple) and widely used in the production of candy, juice, soda, ice cream, and plum.
They are all fruits and vegetables with high anthocyanin content
Antioxidant-rich anthocyanins have increased the economic added value and health effects of edible crops, and more and more scientific research has begun to use the characteristics of anthocyanins and genetic engineering to cultivate high-content anthocyanin crops.
Cultivating "black tulips" is very difficult. Because there is no pure black pigment in the plant pigment, researchers use high concentrations of blue and purple anthocyanins to make the flower color look closer to black.
Canada introduced tomatoes containing anthocyanins, these tomato peels appear purple, not only more nutrients than the original red tomatoes, the shelf life is also longer, the various colors of small tomatoes combined together to sell goods, so that consumers have a refreshing feeling, increase a lot of desire to buy.
Anthocyanins have been studied in the root block for a long time, and the color system of sweet potato seed blocks collected from home and abroad has become more and more abundant. In 2007, Taiwan's Chiayi Agricultural Research Institute successfully cultivated a purple root variety, which is a high anthocyanin variety that also allowed the world to see the "purple sweet potato" for the first time.
And the most amazing thing is the "gem corn" in the United States, where the color of each seed on a corn ear is different, colorful and crystal clear, just like a dazzling gem set on the corn ear, making people want to buy it as a collectible.
Many anthocyanin research and development institutions have published articles to remind consumers not to blindly pursue anthocyanin products, because the market has not yet appeared strict anthocyanin pure products, if you use or eat too many synthetic anthocyanin products, it will have side effects on the body, and the results will be more than worth the loss.
Therefore, the intake of anthocyanins is needed, which can only be achieved through food supplements, such as eating purple-black foods with high blue anthocyanin content, such as black rice, black sesame seeds, purple corn, black goji berries, blueberries, purple grapes, etc.
Most anthocyanin-rich foods require some complex cooking processing, for the fast pace of work and life of the out-of-the-way party, personally cook a simple meal is a luxury, and Zhang Tai and Mulberry Black Goji Berry Yangyuan Cake is a good anthocyanin supplement small snack, both beauty and nourishment, but also to replenish the body's energy.
