Embodiment Construction

[0026] A kind of processing method step of potato coproduction processing potato juice, starch and whole potato starch of the present invention is:

[0027] 1) Remove the soil, stones and wash the potato raw materials first, peel the cleaned raw materials, and transport the raw materials to the brush potato washing machine for cleaning, and manually remove the pits;

[0028] 2) Transport the raw material obtained in step 1) to a slicer for slicing, and then use a dicing machine to cut into 2-8mm raw material particles;

[0029] 3) Transport the raw material particles to the juice extractor for the first juice extraction, and separate the solid and liquid phases;

[0030] 4) Put the solid phase into the enzymatic hydrolysis box, hydrolyze it with cellulase and pectinase for 30 minutes, and then use the juice extractor to squeeze the juice for the second time, and separate the solid and liquid phases again;

[0031] 5) Transport the solid phase part obtained in step 4) to a bel...

Abstract

The invention relates to the technical field of food processing, and concretely relates to a processing method for coproducing a sweet potato juice, starch and total-sweet potato starch by using sweet potato. The method adopting sweet potato as a raw material comprises the following steps: dicing the peeled raw material, crushing the diced raw material, juicing the crushed raw material, dehydrating the juiced raw material, carrying out low temperature drying on the obtained solid phase material to obtain powder, crushing the powder, and screening the crushed powder to obtain screen underflow which is the total-sweet potato starch; and allowing the above obtained liquid part to enter a fresh fruit and vegetable normal juice processing device, processing the liquid part, and separating the processed liquid part to obtain free starch and an NFC sweet potato juice. The method avoids cooking the raw material through blanching, microwave and pre-boiling, guarantees that the product is the sweet potato starch, and reduces loss of nutrients.

Description

1. Technical field: [0001] The invention relates to the technical field of food processing, in particular to a processing method for processing potato juice, starch and whole potato starch through joint production of potatoes. 2. Background technology: [0002] Traditional sweet potato processing is mostly single-product processing, rarely joint production. [0003] Potato flour is a dehydrated product prepared from fresh potato as raw material through drying and other processes. It contains almost all fresh potato ingredients except potato skin. Potato flour processing can be divided into raw flour and cooked flour according to whether fresh potatoes are cooked or not. Raw flour is generally obtained by processing and crushing the dried potato after drying the traditional fresh potato slices. The advantage is that the production process is simple and the cost is low, but the product processing adaptability is poor, and it is greatly affected by the weather. If there is too...
