Abstract

The invention discloses a dried selenium-enriched purple sweet potato processing technology. The dried selenium-enriched purple sweet potato processing technology comprises the following steps of cleaning up, draining, cutting, drying purple sweet potato slices in the sun until semi-dried purple sweet potato slices having moisture content of 45 to 60% are obtained, drying by an air dryer, carrying out sterilization by an air dryer drying-sterilization combined technology, and carrying out vacuum packaging. Through the combination of air-drying and air-dryer drying, the dried selenium-enriched purple sweet potato processing technology does not destroy nutritional values of purple sweet potatoes and retains an original taste of purple sweet potatoes. Dried selenium-enriched purple sweet potato obtained by the dried selenium-enriched purple sweet potato processing technology has a beautiful color and a crispy taste and is rich in nutrients.

Description

technical field [0001] The invention relates to a process method for processing dried selenium-enriched purple sweet potatoes, which belongs to the field of food processing. Background technique [0002] Purple potato is also called black potato, and the potato flesh is purple to dark purple. In addition to the nutrients of ordinary sweet potatoes, it is also rich in selenium and anthocyanins. Purple sweet potato is rich in nutrition and has special health functions. It contains about 20% protein, including 18 kinds of amino acids, which are easily digested and absorbed by the human body, including 8 kinds of vitamins such as vitamin C, B, and A, and more than 10 kinds of vitamins such as phosphorus and iron. Mineral elements, the anthocyanins rich in it have significant antioxidant properties and anti-aging functions; French scientist Dr. Masquelle discovered that anthocyanins are natural and powerful free radical scavengers. Anthocyanins have preventive and therapeutic e...
