Problems solved by technology

[0002] At present, in addition to fresh potatoes, the processing raw materials of potato staple food products on the market mainly include potato powder, potato starch, etc., but these raw materials have some defects to varying degrees. Fresh potatoes are difficult to store due to their high moisture content, short shelf life and transportation issues
In the production of potato starch products, the important nutritional components protein, dietary fiber, and trace elements in potatoes are discarded in the form of waste water and waste residue, which not only causes the lack of nutrition but also brings great pressure to the treatment of waste water and waste residue; The closest product is potato flour. At present, more than 95% of the commercially available flour is cured potato snowflake flour or granule flour. However, since the starch in the potato flour has been gelatinized after ripening, the original potato flour The complete structure of starch has been destroyed, so the original processing characteristics of potatoes have been completely changed, and it is prone to browning, which is not suitable for traditional food production and processing, and its application range is limited, and the unit processing amount is limited, and the processing cost is high. Difficulties for further development of potato products for food applications

Abstract

The invention provides a production and processing technology of raw potato whole powder. The production and processing technology comprises the following steps: pretreating raw materials; cleaning; crushing; homogenizing; performing centrifugation; carrying out light-phase sand removal; concentrating a light phase; premixing; drying; crushing a finished product; and packaging the finished product to obtain the potato whole flour, injecting inert gas into a buffer tank, and maintaining the positive pressure environment in the tank. Compared with the traditional potato whole flour (cooked whole flour), the potato starch is prevented from being gelatinized in the processing process, the inherent characteristics of the original starch are reserved, the browning of the potato whole flour in the processing process is inhibited, the color, aroma and taste and inherent nutrients of potatoes are maintained, the potato whole powder is suitable for long-term storage, and the production and processing technology is wide in application field, is especially suitable for processing staple food products, is beneficial to promoting the industrialization of staple food of potatoes, and ensures the national food safety.
