Description

technical field [0001] The invention relates to a method for producing and processing preserved purple sweet potatoes by using No. 18 Jishu, and belongs to the field of deep processing of agricultural products. technical background [0002] The processing technology of preserved sweet potato originated in the countryside. Roasted preserved potato is a traditional product in the countryside. The common process is to wash, steam, shape, and dry naturally in a well-ventilated place. Beginning in the early 1990s, many local workshops and enterprises began to upgrade the production process of this traditional product, and carried out in-depth research on the selection of special varieties for processing and processing technology. In the modified process, the sweet potatoes are cleaned, peeled, shaped, steamed, saccharified, and then dried naturally for 24 hours in a high-temperature room heated by a fire channel.
