Cold Pitaya Peel

My sister asked me if I knew the pitaya peel contains anthocyanins, and some people made the pitaya peel into a cold dressing. I said I know that anthocyanins, blue plum and wolfberry all contain anthocyanins, especially wild black wolfberry. But I don't know that pitaya also contains it. I just bought the dragon fruit, so I tried to make the dragon fruit skin into a cold dressing.
Anthocyanin is a powerful antioxidant, more than 10 times stronger than carotene, and can be stored in human blood for 75 hours. It can protect the human body from harmful substances-free radical damage, and help prevent a variety of free radical-related diseases. Anthocyanins can enhance the elasticity of blood vessels, protect the inner walls of arteries, lower blood pressure, inhibit inflammation and allergies, improve joint flexibility, promote the regeneration of rhodopsin in retinal cells, improve vision, and have anti-radiation effects. In short, anthocyanins maintain the health of the human body in many ways and bring us many benefits.
Therefore, when eating dragon fruit, try not to discard the inner pink peel. You can scrape it off with a knife and eat it raw, or cut it into thin strips for cold salad. Juicing is also a good choice. It should be reminded that the pitaya peel is not suitable for tea, soup or steaming, because high temperature will cause local degradation of anthocyanins and reduce its nutritional value. "
