Abstract

The invention provides a potato raw flour preparing process by the vacuum drying method and belongs to the technical field of potato processing. The process includes adopting fresh potatoes as raw material, cleaning, peeling and dicing the potatoes, soaking the potatoes through color protecting liquid to protect color, fetching and draining the potatoes before placing into a vacuum drying box to perform vacuum drying; obtaining the potato raw flour after smashing, filtering and packaging. The color, flavor and taste of potatoes can be remained to the utmost extent, the quality of the obtained potato raw flour is high, the protein has the biological activity, protein crosslink occurs to form a gluten network structure during dough making, the processing performance problem is solved when the potato dough is used for noddle and bread processing, and the significance is provided for promoting potatoes to be staple foods.

Description

technical field [0001] The invention relates to a process for preparing raw potato powder, in particular to a process for preparing raw potato powder by a low-temperature vacuum drying method, and belongs to the technical field of potato processing. Background technique [0002] In 2015, the Ministry of Agriculture announced that my country will start the strategy of turning potatoes into a staple food, and promote the processing of potatoes into staple foods such as steamed bread, noodles, and rice noodles. Potatoes will become another staple food besides rice, wheat, and corn. It is estimated that more than 50% of potatoes will be consumed as a staple food in 2020.
