Sweet potato belongs to the angiosperm phylum, dicotyledonous plant class, tubular flower order, spiral flower family, and sweet potato genus. It is the sixth largest food crop in the world and is native to Peru. Sweet potato, as a dual-purpose food for both food and vegetables, has always been favored by people. As early as 2007, sweet potato was named the "Best Vegetable Champion" by the World Health Organization. Sweet potato stems and leaves are known as the "Vegetable Queen", "Longevity Vegetable", and "Anti Cancer Vegetable" in Hong Kong, China and other parts of the world. Sweet potato tubers come in white, yellow, orange red, and purple colors. These tubers contain various essential nutrients for the human body, such as protein, polysaccharides, dietary fiber, carbohydrates, minerals, carotenoids, vitamins, linoleic acid, lysine, folate, and more. In recent years, researchers have extracted various bioactive substances from this type of plant, including sweet potato peptides, polysaccharides, polyphenols, anthocyanins, flavonoids, etc. These bioactive substances play an important role in lowering blood pressure, blood sugar, delaying aging, protecting body functions, antibacterial, antioxidant, anti-tumor, and anti-cancer effects.
