Albumin is a viscous colloidal substance, which has detoxification effect on heavy metal poisoning. Due to the neglect of environmental protection, various water resources are polluted by heavy metals, and the content of heavy metals in drinking water and food exceeds the standard. However, when albumin meets heavy metal ions in the human body, it will combine with them and then be excreted, which plays a role in detoxification. So eating pitaya rich in albumin can avoid the absorption and poisoning of heavy metal ions. 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.
