Wolfberry is a kind of food that many people use for health care in daily life. The health care effect of black wolfberry is much better than that of red wolfberry. Black wolfberry contains special anthocyanin. According to different water quality, the color of the water is different, mainly blue and purple. It is recommended to use water below 60 ℃ for brewing to avoid damaging anthocyanin.
What color is black wolfberry after soaking in water?
Black wolfberry will show different colors under different water quality (i.e. different pH value) and different water temperature. For example, the color of acid water (tap water, mountain spring water, etc.) is purple, while that of alkaline water (mineral water, etc.) is blue. It is recommended to use water below 60 ℃ for brewing, because too high temperature will degrade anthocyanin.
The color of black wolfberry in water, there will be very interesting discoloration phenomenon when brewing black wolfberry. If you use tap water (water temperature is lower than 60 ℃), you will immediately feel drawn and turn blue. If you use mineral water (water temperature is lower than 60 ℃), you will immediately feel drawn and turn purple and turn purple and black. If you use boiled water (tap water), you will immediately feel drawn and turn blue. If you wait for a while, the color will become lighter (the temperature is too high to degrade the cyan) After brewing, some fruits will be white and transparent.
Even in the same water quality, the change of water temperature will also cause the change of bubble color. Because in the hot water state, the concentration of hydrogen ions ionized from the aqueous solution increases. According to the pH value formula of the solution, the pH value of water decreases with the rise of temperature. If the pH value of water is greater than 7, the water quality will be alkaline; if it is less than 7, the water quality will be acid. In other words, hot water is alkali, cold water is acid. The commonly used acid-base indicator 'litmus', which is a blue purple powder, is a blue pigment extracted from plants and can be partially soluble in water and appear blue.
Generally speaking, the water quality in the north is alkaline; the water quality in the south is acidic; therefore, the water soaked by black wolfberry in the South will be purple. It is suggested that when people in the South drink black wolfberry, they can choose the water with strong alkaline. Of course, the color of black wolfberry does not affect the absorption of anthocyanin. Only the best 60 degrees or so of water immersion, too high temperature, will affect the release of active substances. 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 light fruit flavor we feel when we drink black wolfberry.
How does black wolfberry change color after being soaked
1. Wash the cup and pour water into it: wash the cup and pour 400ml warm water or cold water below 60 ℃.
2. Add Lycium barbarum: put 2g (about 30 grains) of black Lycium barbarum into water directly.
3. Static drinking: watch the release of anthocyanins, the color is more and more deep, pleasing to the eye.
4. Repeated brewing: when 1 / 3 of water is left each time, water can be added again until there is no color.
