Why does black wolfberry turn blue when soaked in water? What is the best water for black wolfberry

Black Lycium barbarum has high nutritional value, and also contains very rich natural proanthocyanidins. So, why does black wolfberry change color? Why does water with different colors have different colors? Black wolfberry with what water brewing better?

Efficacy and function of Lycium barbarum

1. Lycium barbarum L. is the most effective antioxidant in nature, which can replenish blood and calm nerves, improve sleep, and prevent skin wrinkles. It can not only prevent the early formation of skin wrinkles, but also supplement nutrition and eliminate harmful free radicals in the body.

2. Anthocyanins in Lycium barbarum L. are natural sunshades, which can prevent ultraviolet rays from damaging the skin.

3. Lycium barbarum L. has obvious function of lowering blood lipid and regulating lipid metabolism, which has a positive effect on the prevention of cardiovascular disease. Lycium barbarum has hypoglycemic effect. Lycium barbarum polysaccharide can significantly enhance the activity of superoxide dismutase in damaged islet cells, improve the antioxidant capacity of islet cells, reduce the damage of peroxide on cells, and reduce the production of malondialdehyde. Therefore, Lycium barbarum polysaccharide has a certain protective effect on islet cells.

4. Black wolfberry is a natural nickel supplement product. Chromium and nickel are also essential trace elements for human body, but when the content is high, it will lead to poisoning. Chromium is closely related to glucose metabolism, lipid metabolism, protein synthesis and nucleic acid metabolism in human body. The content of chromium in Lycium ruthenicum is lower than that in normal milk (5 ~ 15ug / ml), which will not cause poisoning to human body. The content of nickel in Lycium ruthenicum L. is higher than that in grain pickled vegetables (0.1-0.3 & mu; g / g), but this concentration range will not pose a toxic threat to human body. Therefore, Lycium ruthenicum L. can be used as a single pure nickel supplement. Lead and cadmium are heavy metal pollution elements strictly controlled by environmental organizations, which are harmful to human body but not beneficial. The content of lead and cadmium in black wolfberry is much lower than that in common plants (0.5-3.0 & mu; g / g).

5. Black wolfberry is a natural cobalt supplement. Cobalt has low toxicity to human body, participates in vitamin B12 composition and stimulates hematopoiesis. The content of cobalt in Lycium ruthenicum is much higher than that in green leafy vegetables (0.2-0.6ppm dry weight), but this concentration range will not pose a toxic threat to human body. Lycium ruthenicum has the function as a pure cobalt supplement.

6. Black wolfberry has the effect of anti-cancer and anti-cancer. The most prominent component of Lycium barbarum is anthocyanin, which is a good pigment and a powerful antioxidant. It can prevent premature aging, enhance vascular elasticity, inhibit allergy and inflammation, and improve joint flexibility. Cancer is also caused by the destruction of genetic material (DNA) by free radicals. By protecting our genetic material, anthocyanins will indirectly protect us against cancer. Although it is long-term, anthocyanins do have an indirect protective effect. The effect of anthocyanins in scavenging free radicals can also prevent cancer cells from spreading smoothly, so as to protect more healthy cells from being eroded by cancer cells. On the other hand, some cancers form tumors by dissolving tissues and cells. These cancer cells produce lysozyme and proteoglycan, and anthocyanins can protect proteins from proteoglycan.

Lycium ruthenicum contains a certain amount of essential fatty acids, 8 kinds of essential amino acids and VC. The most significant is that it contains more reducing sugar and pigment. Its pigment is the active component of antioxidant and anti-aging of Lycium ruthenicum, which plays a role in anti-aging and has far-reaching development potential.

The color change of black wolfberry soaked in water was as follows

The color of black wolfberry soaking in water, when brewing black wolfberry, there will be a very interesting phenomenon of discoloration. When brewing with tap water (water temperature below 60 ℃), it immediately feels like drawing and turns blue, and after a while, it turns blue ink; when brewing with mineral water (water temperature below 60 ℃), it immediately feels like drawing and turns purple, and after a while, it turns purple black; After brewing with boiling water (tap water), there will be a sense of silk drawing and blue immediately. After waiting for a moment, the color will become lighter (due to the degradation of anthocyanins due to too high temperature) & hellip; & hellip; after brewing, some fruits will be white and transparent.

Why does black wolfberry change color when soaked in water?

The reason why black wolfberry will change color in water is that the anthocyanins in black wolfberry dissolve in water. Anthocyanin is a kind of water-soluble pigment, and it is particularly sensitive to acid and alkali. It can change different colors with the acid and alkali of the environment. In acid water, it is purple (purple, purple red, iron red, etc.), in alkaline water, it is blue (blue, blue-green, Lake blue, etc.).

Therefore, black wolfberry in different water bubble out is not the same color, generally with mineral water bubble is purple, with home tap water bubble is blue. Black wolfberry soak water to use 60 degrees below warm water or cold water, can not use boiling water, because the black wolfberry anthocyanins and some nutrients afraid of high temperature.

The color change of black wolfberry soaking in water is generally related to the water quality, but it has little connection with black wolfberry. Black wolfberry will show different blue and purple because of the change of pH and temperature of water.

Black wolfberry with what blister best?

Generally speaking, the water quality in the north is alkaline; the water quality in the south is acidic; therefore, the water soaked in black wolfberry in the South will be purple. It is suggested that when people in the South drink black wolfberry, they should choose the water with strong alkaline. Of course, the color of black wolfberry does not affect the absorption of anthocyanins. Only the best 60 degree water immersion, too high temperature, will affect the release of active substances. If the temperature is too low, the polysaccharide and other components in black wolfberry are not easy to release, which will affect the taste, that is, the faint fruit flavor we feel when we drink black wolfberry.

How to soak black wolfberry in water?

1. Wash the cup and pour water: wash the cup and pour about 400ml of warm or cold water below 60 ℃.

2. Add wolfberry: put 2g (about 30) black wolfberry directly into water.

3. Standing drinking: quietly watching the release of anthocyanins, the color is getting darker and darker, pleasing to the eye.

4. Repeated brewing: when there is 1 / 3 water left each time, add water to brew again until there is no color.

Tips: it is better for adults to put 3 ~ 5g a day. There is no strict regulation on how much to put each time. You can put it all at once and then brew it repeatedly until there is no color at last. You can also put a little bit each time and brew it several times separately.
