Embodiment 1

[0014] Embodiment 1, the preparation method of sweet potato flour slag dietary fiber,

[0015] A. Fermentation and impurity removal: Take 500 kg of sweet potato flour residue with 70% water content remaining from the processed starch and pour it into the fermentation tank, add 250 kg of physalis left over from starch production in the starch factory, stir for 10 minutes, and naturally ferment for 40 hours at 20°C. The starch and other substances in the sweet potato powder dregs are suction-filtered after the fermented pulp residue, and the acid pulp water is filtered out for reuse next time. neutral,

[0016] B. Alkalization: Pour the sweet potato powder slag that cleans and press filter in the stirring reaction pot, add clear water in the ratio of 1: 10 of dry sweet potato powder slag weight, add sodium hydroxide in the ratio of 6% of dry sweet potato powder slag weight, Then stir and heat at 50°C, continue to alkalinize for 3 hours, add acid to neutralize to a pH value of 6...

Embodiment 2

[0021] Embodiment 2, sweet potato residue is produced dietary fiber,

[0022] A. Fermentation and impurity removal: Take 500 kg of sweet potato powder residue with 70% water content remaining from processed starch and pour it into the fermentation tank, add 350 kg of physalis left over from starch production in the starch factory, stir for 10 minutes, and ferment naturally for 36 hours at 20°C. The starch and other substances in the sweet potato powder dregs are suction-filtered after the fermented pulp, and the acid slurry water can be reused next time. After the suction filtration, the potato dregs are cleaned, impurities are removed, and the pH value is medium. sex,

[0023] B. Alkalization: Pour the sweet potato powder slag that cleans and press filter in the stirring reaction pot, add clear water in the ratio of 1: 10 of dry sweet potato powder weight, add sodium hydroxide in the ratio of 6% of dry sweet potato powder weight, and then Stir and heat at 80°C, continue to a...

Abstract

The invention provides a process for preparing yam powder slag dietary fabrics, which consists of the steps of fermenting, rouging, alkalizing, hydrolyzing, decolorizing, extruding, drying, squeezing, puffing and disintegrating.

Description

Technical field [0001] The invention belongs to the preparation method of food, especially the preparation method of food rich in cellulose. Background technique [0002] As a pure natural dietary fiber, sweet potato dietary fiber is widely used in food production and processing industries. It can be made into capsules and eaten directly, and can also be used as a raw material or additive of food, and added to bread, noodles, biscuits, pastries, candies and various small foods to stabilize the product structure, reduce water loss, and extend shelf life. . In addition to being used as a food additive, sweet potato dietary fiber can also be used as a health food for special groups. After people eat it, it absorbs water and expands in the human digestive tract, promotes gastrointestinal peristalsis, excretes various toxins in the feces, and prevents constipation, hemorrhoids and other diseases . At the same time, it can delay the absorption of carbohydrates and has a certain...
