Sweet potato is an important industrial raw material crop, like edible corn starch, which is also a new energy crop and a natural feed crop. Deep processing of high-quality sweet potato starch into modified starch is also a bright spot in the comprehensive development of sweet potato. Compared with the original starch, the starch processed by modern machinery and new technology has transparency, high viscosity, anti-aging, good stability and good water retention. It is widely used in food, medicine, chemical and other industries. . Potato chemical products have become the main raw materials for chemical products such as lactic acid, citric acid, disposable tableware and degradable agricultural film.

U7彩票U7CCAt present, China's domestic market demand for various deep-processed sweet potato starch reaches millions of tons, but domestic processing volume is less than half. As a modified starch (acid-modified starch, oxidative degeneration powder and carboxyalkyl modified starch) that is in high demand in the food, paper, textile, petroleum and other industries, China's annual demand is over 4 million tons, and only the instant noodle market needs to be close. 300,000 tons, the country's output is only 100,000 tons, and the rest are dependent on imports. Therefore, there is a very large market space in the use of sweet potato to process modified starch.

In addition, the sweet potato comprehensive development project also includes: development of fully degradable non-toxic and harmless agricultural mulch film, packaging materials, development of natural pigments, snack foods, functional beverages, protein feed and bio-polysaccharides, protein, flavonoids, polyphenols series products Wait. The development of high-tech industrialization of sweet potato comprehensive processing will effectively promote the prosperity and development of the animal husbandry, feed industry, food processing industry, biomedicine, chemical industry, machinery industry and other industries in the vast sweet potato producing areas, forming a industry to drive many industries. A benign development situation can produce positive and good social benefits, while at the same time having significant economic benefits.

The market development prospects of sweet potato deep processing are good, conforming to the trend of the times, accelerating the transformation and development of modern mechanized agricultural industry, actively exploring new energy sources, opening up innovative models for clean energy development, taking into account green environmental protection, safety and health, and realizing sweet potato. The industry characteristics in the field of deep processing create greater industrial benefits.

U7彩票U7CCSweet potato starch demand

At present, the demand for sweet potato starch in the domestic market alone is more than 2 million tons, and the production volume is far less than this figure. With the change of people's dietary consumption concept, the market demand for sweet potato starch will become larger and larger, and the space for planting sweet potato and the processing space for starch will become larger and larger. Due to the wide use of products, low raw material prices, and large value-added space for processing and development, the prospect of sweet potato starch processing industry is promising.

U7彩票U7CCSweet potato is convenient for fans

Fans are a traditional food in our country. In the past few years, a new product has appeared in the fan market. Sweet potato is a convenient fan. It is made from sweet potato starch.

100 kg of sweet potato can generally produce 20-30 kg of sweet potato starch. (This is because different sweet potato varieties and different starch content, different starch processing equipment used, resulting in different powder extraction rate and starch extraction rate.) A pound of sweet potato starch probably Can make a pound of sweet potato vermicelli. At present, the purchase price of sweet potato is about 0.35 yuan / kg, the pure sweet potato starch is above 4-4.5 yuan / kg, the price of sweet potato vermicelli fans is more than 10 yuan / kg, the price is a dozen times higher. The deep processing of sweet potatoes into fans can not only achieve high economic benefits, but also solve a series of problems such as farmers' difficulties in selling potatoes.

At present, sweet potato convenience fans have been exported to Europe, America, Australia and Southeast Asia. Now the product is booming and the development prospects are very broad.
