Production processing technology for dried sweet potatoes

Abstract

A production processing technology for dried sweet potatoes comprises the following steps: A, cleaning sweet potato and peeling; B, putting cleaned peeled sweet potato in a pressure cooker for high-pressure boiling; C, taking sweet potato from the pressure cooker, mashing to obtain sweet potato paste; D, adding proper amount of yeast into sweet potato paste and fully stirring; E, standing the sweet potato paste fully mixed with yeast for 3 h; F, performing compaction molding on sweet potato paste subjected to fermentation through a mold so as to obtain sweet potato cakes; G, putting sweet potato cakes in a food steamer and steaming for 1 hour; and H, drying steamed sweet potato cakes in air and performing vacuum packaging. According to the production processing technology, cleaned sweet potato is subjected to high-pressure boiling, boiled sweet potato is mashed into sweet potato paste which is added with yeast and is fully stirred, after the sweet potato added with yeast and fully stirred is stood for 3 hours, sweet potato paste is subjected to fermentation under the effect of yeast, and fermented sweet potato paste is compacted for preparing sweet potato cakes, and the sweet potato cakes are steamed for 1 hour, so that sweet potato cakes are soft in mouthfeel and cannot harden.

Description

technical field

[0001] The invention relates to a production and processing technology of dried sweet potatoes. Background technique

[0002] Sweet potato has become a favorite food due to its rich nutrition and low price. It can be used not only as a staple food, but also as a snack. However, sweet potatoes are softer and easier to eat only after they have just been cooked. After the sweet potato becomes normal temperature, its taste is hard, making some elderly people unable to eat it. Contents of the invention

[0003] The problem to be solved by the present invention is to provide a production and processing technology of dried sweet potatoes, which can have a soft taste at normal temperature.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: a production and processing technology of dried sweet potatoes, comprising the following process steps:

[0005] A: Clean the sweet potatoes and peel them;...
