Abstract

The invention provides a technology for preparing potato flour by an electrothermal forced air drying method, and belongs to the technical field of potato processing. The technology includes taking a fresh potato tuber as a raw material, cleaning, peeling and dicing the tuber, soaking the tuber in color protection liquid for color protection, taking out the tuber, draining off water, and putting the tuber in an electrothermal forced air dry box to perform electrothermal forced air drying and dehydrating; smashing, sieving and packaging the tuber to obtain the potato flour. The technology has the advantages that the temperature for electrothermal forced air drying and dehydrating is controlled to be lower than potato albuminous degeneration temperature and starch pasting temperature, so that color, smell and taste of a potato can be kept to the utmost to obtain a high-quality final product; protein of the prepared potato flour has biological activity, and protein crosslinking can be achieved during kneading to form a gluten network structure, so that the processing performance problems in processing of potato paste into noodles and steamed buns are solved, and the technology has a great significance in promotion of potatoes serving as staple food.

Description

Technical field [0001] The present invention involves a preparation process for potato -raw powder, and especially involves a process of potato raw powder for all potato pink. It belongs to the field of potato processing technology. Background technique [0002] Potato is an important food and economic crop in my country. Its planting area and output are the first in the world.In 2013, my country's total potato output exceeded 80 million tons, which was the fourth largest grain crop located after rice, corn, and wheat.In January 2015, the Central Document No. 1 and the Ministry of Agriculture took potato as the strategic development of the main grainization, which will be more important in ensuring the security of national food and the promotion of national and economic development. [0003] Potato food is an ideal choice: fresh potato tubers are composed of about 80%of water and 20%of dry substances, and each 100 G potato tubs contain approximately 18 G carbohydrates and 2 G pro...
