Autumn ripe vegetables are cabbage, potatoes, carrots, carrots, eggplants, celery, lotus root, beans, tomatoes and so on; potato tubers contain a large amount of starch, can provide the body with a wealth of calories;

And rich in protein, amino acids and a variety of vitamins, minerals, especially its vitamin content is the most complete of all food crops in Europe and the United States, especially in North America. North America, the potato has long been the second staple food.

Harvest

Harvesting

Reaching physiological maturity, early varieties of mid- to late August, late varieties of early to mid-September harvest. A week or so before harvest, the potato field mechanical cut seedling or chemical seedling extermination, and will be cleaned out of the plot of stems and leaves. Digging depth should be reasonable when harvesting, to prevent the loss of potato and broken skin injury potato. Shipping should be light, transportation and storage to prevent sun, rain and frost damage.

Main value

Potato is one of the high-yield crops with development prospects, but also one of the top ten popular nutrition and health food. Potato is an important food crop after rice, corn and wheat.

Because of its high and stable yield, wide adaptability, full nutritional content and long industrial chain and by the world's high attention, potato seed potatoes and a variety of processed products have become an important part of the global economic trade.

Economic value

crops. In the south of China's northeastern, northern and eastern China, potato as an early spring vegetables become an important crop of rural wealth; in the south of eastern China and most of southern China, potato as a winter crop and rice rotation, the export of fresh potatoes can be a great economic benefits; in the northwestern and southwestern mountainous areas, the potato as a major food crop plays an important role.

In recent years, potato food processing, starch processing industry rapid development. In the food processing industry, the potato as raw material, can be processed into a variety of frozen convenience food and leisure food.

such as dehydrated products, fried potato chips, frozen French fries, puffed food, etc., while it can also be further processed into fruit glucose syrup, citric acid, biodegradable plastics, adhesives, enhancers, and a variety of additives on the medicine.

Potato starch in the world market is more competitive than corn starch, potato high-yielding countries will be about 40% of the total output for starch processing, the world's starch production of 25% from potato.

Compared with starches from other crops, potato starch has high pasting degree, low pasting temperature, good transparency, strong adhesion and high tensile strength. Potato modified starch has applications in many fields, such as the processing of derivatives, the production of fructose syrup, the production of citric acid, and the production of biodegradable plastics.

According to expert estimates: potato processing into ordinary starch can double the value-added, special starch can be more than ten times the value-added, the production of biogelatin can be more than 60 times the value-added, the processing of french fries, potato chips, puffed food can add value to the value of 5 ~ 10 times.
