There are four farmers in Mancheng County, Hebei Province, who have used fruits such as sweet potatoes, carrots, and apples to produce fruits in Beijing, Tianjin, Shenyang, and other major cities. They have created more than 300,000 yuan worth of output in half a year. Luping Zhaowang Taiwan Food Factory in Hebei Province, using sweet potatoes to produce more than 5,000 kilograms of fruit wolfberry, test sales in Shijiazhuang, Zhangjiakou, Datong city, welcomed.
Production Method: The use of sweet potato is not complicated. Wash the sweet potatoes first, peel and cut them into cubes, cook them in a pot, add 3 kg of sugar for every 10 kg, and then add appropriate amounts of citric acid, sulfurous acid and 200 g of honey sugar. When the sweet potatoes are ripe, remove them at 50. The baking room at about °C is cooked. About 2.5 kilograms of sweet potatoes can be made into 1 kg of preserved fruit.
Vitamins are a kind of trace organic substances that humans and animals must obtain from food in order to maintain normal physiological functions. They play an important role in the growth, metabolism, and development of the human body. In the body, this kind of substance can neither be a raw material for body tissue nor a source of energy, but a kind of regulating substance, which plays an important role in material metabolism.
From the point of view of chemical structure, various vitamins are very different or even unrelated. Therefore, vitamins are usually classified according to their physical properties. They can be divided into fat-soluble vitamins (such as vitamin A, D, E, K, etc.) and water-soluble vitamins ( Such as vitamin C, vitamin B1, B2, B6, B12, pantothenic acid, PP, biotin, folic acid, choline, etc.). Water-soluble vitamins are easily soluble in water but not soluble in organic solvents. They are stored in the body after absorption. Excessive amounts are mostly eliminated in the urine; fat-soluble vitamins are easily soluble in organic solvents but not in water. They can be absorbed by the body with fat and stored in the body, and the excretion rate is not high.
From the perspective of obtaining methods, vitamins can be divided into natural products and chemical synthetic products. Because natural vitamins are limited by raw materials and extraction technology, their yields are low, and their prices are high. Therefore, chemical synthesis takes the lead, accounting for about 80% of the total vitamin output. Among the various segments of the vitamin industry, vitamin B, vitamin E, vitamin C and vitamin A have the largest market shares, 33%, 30%, 21% and 13% respectively. Other vitamins have a smaller market share, accounting for only 3%.
