Sweet potato is a nutritious and rich natural nourishing food, rich in protein, fat, polysaccharide, phosphorus, calcium, potassium, carotene, vitamin A, vitamin C, vitamin E, vitamin B1, vitamin B2 and 8 amino acids. According to scientists' analysis, its protein content is 7 times more than that of rice; its carotene content is 3.5 times that of carrots; its vitamin A content is 100 times that of potatoes; its sugar, calcium, vitamin B1, and vitamin B2 contents are all higher than those of rice and flour. Each 100g edible portion of fresh potato cubes contains 29.5g of carbohydrates, 0.2g of fat, 20g of phosphorus, 18g of calcium, and 0.4g of iron. These substances play an important role in promoting the activity of human brain cells and secreting hormones, enhancing the body's disease resistance, improving immune function, and delaying mental decline and body aging. The Japanese Ministry of Health has listed it as an important food for dietary therapy.

Weight loss food: Sweet potato has an extremely low fat content (0.2), which is unmatched by other foods. The content of unsaturated fatty acids is very rich. Take it as a staple food and insist on eating it once a day. Its rich fiber makes people feel "full" and relaxed in the stomach. At the same time, it can not only prevent the absorption of fat and cholesterol in the intestines, but also decompose cholesterol in the body and promote lipid metabolism. It can effectively prevent overnutrition in the human body and resist the occurrence of obesity, thereby achieving the purpose of weight loss.

Longevity food: Sweet potato As early as the Ming Dynasty, Chinese medical scientist Li Shizhen listed it as a "longevity food". In recent years, with the development of society, the "social status" of sweet potatoes has also increased, and many countries in the world call it "longevity food." Its function is to quickly neutralize the acidic substances produced by foods such as rice, noodles, meat, and eggs in the human body, maintain the weak alkaline balance of the human blood, and convert carotene into the human body into vitamin A. Both raw and cooked sweet potatoes contain mucin. This mucin is a mixture of polysaccharide proteins, which are collagen and polysaccharide substances. It can not only effectively prevent the deposition of fat on cardiovascular walls, maintain and increase the elasticity of arterial blood vessel walls, reduce the accumulation of subcutaneous fat, prevent the shrinkage of connective tissue in the liver and kidneys, but also prevent fatigue, restore energy, and prevent constipation. , strengthen the body and prolong life. Disease prevention: Potato cubes are rich and special in vitamin C, vitamin E and potassium. Among them, vitamin C can significantly enhance the body's resistance to various viruses such as colds; vitamin E can promote people's sexual desire and delay aging. Potassium can effectively prevent the occurrence of high blood pressure, stroke and cardiovascular disease. Japanese scientists have found that potato cubes contain a type of collagen mucus protein that cannot be obtained from chicken, duck, or fish. This substance can maintain the elasticity of human arterial walls and effectively prevent arterial atherosclerosis.

Good medicine for treating diseases: It has high medicinal value. Ancient Chinese medical scientists have long discussed the efficacy of potato cubes in curing diseases. Li Shizhen's "Compendium of Materia Medica" of the Ming Dynasty states: "Sweet potatoes have the effects of replenishing deficiency, replenishing qi, strengthening the spleen and stomach, and strengthening kidney yang." "Jinshu Zhuanxilu" says: "It can cure dysentery, alcohol-accumulated heat and diarrhea, damp-heat, infantile malnutrition" and other diseases. The milky white slurry in raw potato cubes is a good medicine for laxative, promoting blood circulation, and inhibiting muscle spasms. It is also effective in treating eczema, centipede bites, herpes zoster and other diseases. The method is to mash the raw potato pieces, squeeze the juice, and apply it to the affected area. It will heal after several times. High-quality feed: Sweet potatoes are high-quality feed for fattening pigs. They can be eaten alone or mixed with other grains, such as corn, green grains, or grass and leaves. The leaves and vines can be eaten fresh, or dried and crushed, blanched and cooked with grain bran. One month before the pig body is finalized (the skeleton is elongated) or slaughtered, eating cooked potato pieces alone or mixed with corn has a particularly good fattening and fattening effect. It is like using a "fattening agent", generally increasing 0.5-0.8kg of meat per day. This This is a successful experience in fattening pigs in Chenggu County, Shaanxi Province. Avoid eating potato pieces with black spot disease to prevent fat pigs from being poisoned and dying.

Wide range of uses: Potato cubes are suitable for processing a variety of products, including making soy sauce, candied fruit, maltose, calcium gluconate, brewing liquor, and extracting alcohol. The potato residue after starch extraction can then produce calcium citrate. Its starch is an important raw material for the production of plasticizers and advanced absorbent resins. The processed dried potatoes are mainly exported to Southeast Asia.

Extracted starch: Its starch has a wide range of consumption. It can be mixed with various meats to make food balls, mixed with flour to steam cold skin, or can be used alone to make pancakes, stir jelly, etc.
