Method for producing whole sweet potato powder

Abstract

The invention discloses a method for producing a whole sweet potato powder, which takes fresh sweet potato as a raw material, the method comprises the following steps: cleaning, automatically refining, removing stones and sands, refining and concentrating, dehydrating and drying to obtain the product. The method of the invention is suitable for large scale production of edible sweet potato starch, and is capable of realizing the industrialized management and substantially raising the production efficiency. The whole sweet potato powder prepared by the method of the invention keeps the dietary fiber, carotene, vitamin, protein, polysaccharide and anthocyanin as well as other nutrition components in sweet potato residue, is capable of improving the intestinal function of human body and preventing the constipation and intestinal diseases, and is beneficial to human health.

Description

technical field [0001] The invention relates to a whole sweet potato powder and a production method thereof, belongs to the technical field of food processing, and is suitable for producing whole powder series products of sweet potato or similar raw materials. Background technique [0002] The processing and production of existing sweet potato powder generally adopts the processes of cleaning, peeling, rinsing, slicing, cooking, mud making, drying, crushing and sieving, crushing, collecting and dust removal, and packaging of finished products. Some methods also add emulsification and dispersion in the production process. The main disadvantages and deficiencies of the above methods are pre-cooking, blanching or microwave processing of sweet potatoes to mature pulp, and then drying to make whole powder. The actual whole powder is cooked powder, and the viscosity of cooked sweet potato pulp is large. The mud is still added with a dispersant, and it is also easy to agglomerate i...

[0002] The processing and production of existing sweet potato powder generally adopts the processes of cleaning, peeling, rinsing, slicing, cooking, mud making, drying, crushing and sieving, crushing, collecting and dust removal, and packaging of finished products. Some methods also add emulsification and dispersion in the production process. The main disadvantages and deficiencies of the above methods are pre-cooking, blanching or microwave processing of sweet potatoes to mature pulp, and then drying to make whole powder. The actual whole powder is cooked powder, and the viscosity of cooked sweet potato pulp is large. Mud is still added with dispersant, it is also easy to agglomerate in the subsequent drying process, and it is difficult to crush, thus affecting production efficiency
