Embodiment 1

[0031]Wash and peel the kudzu root, chop it and dry it at low temperature. Take 150kg of the kudzu root after crushing, add 300L ethanol aqueous solution to extract at room temperature for 35 minutes, and filter it through a ceramic membrane once to obtain filtrate I and filter residue I. Add 15L of glucoamylase solution, 20L of pectinase solution and 25L of cellulase solution to filter residue I, and carry out mixed enzymolysis at 30°C for 10 hours to obtain an enzymolysis solution. The enzymolysis solution was sterilized at 110°C for 20-30 minutes, then inoculated with 12 kg of yeast powder, anaerobically fermented for 3 days, and then inoculated with 20 kg of acetic acid bacteria powder for aerobic fermentation for 3 days to obtain a fermented product. The filtrate I was concentrated to dryness under reduced pressure at 55°C to obtain a dry product. Add dry matter to the fermented product, stir well and centrifuge at 8000rpm for 20 minutes to obtain the supernatant (that is...

Embodiment 2

[0033] Wash and peel the kudzu root, chop it and dry it at low temperature. After crushing, take 240kg kudzu root, add 700L ethanol aqueous solution to extract at room temperature for 35 minutes, and filter it through a ceramic membrane once to obtain filtrate I and filter residue I. Add 20L glucoamylase solution, 25L pectinase solution and 35L cellulase solution to the filter residue I, and carry out mixed enzymolysis at 35°C for 10 hours to obtain an enzymolysis solution.

[0034] The enzymatic solution was sterilized at 121° C. for 25 minutes, then inoculated with 12 kg of yeast powder, anaerobically fermented for 3 days, and then inoculated with 20 kg of acetic acid bacteria powder for aerobic fermentation for 3 days to obtain a fermented product. The filtrate I was concentrated to dryness under reduced pressure at 65°C to obtain dry matter. Add dry matter to the fermented product, stir evenly and centrifuge at 8000rpm for 20 minutes to obtain the supernatant (that is, fer...

Abstract

The invention provides a radix puerariae dietary fiber product. The radix puerariae dietary fiber product is made from the following raw materials in parts by weight: 50-100 parts of radix puerariae and 20-40 parts of konjac powder. The radix puerariae dietary fiber product is made through steps of performing enzymolysis, performing fermentation, performing filtration, performing vacuum treatmentand performing drying. According to the radix puerariae dietary fiber product disclosed by the invention, radix puerariae isoflavones type substances are obtained through alcohol extraction, so that destruction of microorganism fermentation to functional substances is effectively prevented, and later through cellulose adsorption, the stability of the radix puerariae isoflavones type substances canalso be improved; besides, a radix puerariae fermented vinegar product is also obtained; in a manner of adding the konjac powder, the edibility of dietary fibers can be effectively improved, and thepurpose that the radix puerariae isoflavones type substances adsorbed by the dietary fibers are in slow release can be realized.

Description

technical field [0001] The invention relates to a kudzu root dietary fiber product and a preparation method thereof, belonging to the technical field of food processing. Background technique [0002] Pueraria lobata is the dried root of the leguminous plant Pueraria mirifica, commonly known as Pueraria mirifica. Excavated in autumn and winter, cut into thick slices or small pieces while fresh; dry. Perennial vines, up to 10 meters long, covered with yellow-brown coarse hairs. Root tubers are thick. Alternate leaves; long stalk; 3 compound leaves, the stalk of the leaflet at the top is longer, the leaf blade is diamond-shaped and round, sometimes with 3 wavy lobes, 8-19 cm long, 6.5-18 cm wide, sharp at the apex, round at the base Shaped, both sides are covered with white pubescent pubescence, denser below; lateral leaflets are smaller, elliptic or diamond-shaped elliptic, sometimes with 2-3 wavy lobes. The raceme is axillary, the total pedicel is densely covered with yel...
