Pitaya is rich in nutrition and unique in function, which has excellent effects on human health. It contains plant albumin and anthocyanin, rich vitamins and water-soluble dietary fiber, which are rare in general plants. Albumin is a viscous and colloidal substance, which has detoxification effect on heavy metal poisoning. Due to the lack of attention to the treatment and recycling of industrial wastewater and waste, various water resources have been seriously polluted by heavy metals. In addition to direct drinking water poisoning, human ingested food is also prone to heavy metal poisoning.
When albumin meets heavy metal ions in the human body, it will automatically combine with heavy metal ions and be eliminated from the body by the excretory system, which plays a role in detoxification. Therefore, eating pitaya rich in albumin can avoid the absorption of heavy metal ions and poisoning. Albumin also has a protective effect on the stomach wall. Moreover, the albumin in the flowers, fruits and stems of pitaya is excellent and stable, and the polymerization of these albumin constitutes the main component of cactus mucus.
