Embodiment 1

[0039] S1. Wash the fresh Pueraria lobata, remove the epidermis, scrape off the black skin, and set aside;

[0040] S2. Rinse the Pueraria lobata root treated in step S1, and immediately put it in the color protection solution to soak for 120 minutes; the color protection solution includes 0.1% vitamin C, 0.2% citric acid and 0.1% EDTA by mass percentage. The amount is water.

[0041] S3. Grind and beat the color-protected kudzu root, add 0.2% cellulase according to the mass percentage of processed kudzu root, treat it with ultrasonic for 15 minutes under 400W power, and then treat it with colloid milling and homogenization for 20 minutes to obtain kudzu root Slurry filtration, collecting the filtrate and filter residue obtained by filtration;

[0042] S4. Add 0.5% of the mixture of cellulase and amylase according to the mass percentage of the filter residue to the filter residue obtained in step S3, and then homogenize it with colloid milling for 45 minutes, filter and combine the ...

Embodiment 2

[0045] S1. Wash the fresh Pueraria lobata, remove the epidermis, scrape off the black skin, and set aside;

[0046] S2. Rinse the Pueraria lobata root treated in step S1 and immediately put it in the color protection solution for 240 minutes; the color protection solution includes 0.3% vitamin C, 0.1% citric acid and 0.1% EDTA by mass percentage. The amount is water.

[0047] After this step is completed, the color-protected Pueraria lobata root is crushed to 30 mesh particles, then dried to 20% water content by microwave, and then extruded by an extruder for low temperature and high pressure puffing treatment. During the treatment, the extruder is controlled. The internal temperature is 120°C, the pressure in the extrusion chamber is 1MPa, the screw speed is 1300r / min, and the material stays in the extruder for 20 seconds.

[0048] S3. Grind and beat the color-protected kudzu root, add 0.4% cellulase according to the mass percentage of the kudzu root to be processed, treat it with ...

Embodiment 3

[0052] S1. Wash the fresh Pueraria lobata, remove the epidermis, scrape off the black skin, and set aside;

[0053] S2. Rinse the Pueraria lobata root treated in step S1, and immediately put it in the color protection solution for 180 minutes; the color protection solution includes 0.25% vitamin C, 0.15% citric acid and 0.1% EDTA by mass percentage. The amount is water.

[0054] After this step is completed, the color-protected Pueraria lobata root is crushed to 40 mesh particles, then dried to 18% water content by microwave, and then extruded by an extruder for low-temperature and high-pressure puffing. During the treatment, the extruder is controlled. The internal temperature is 120°C, the pressure in the extrusion chamber is 1MPa, the screw speed is 1300r / min, and the material stays in the extruder for 20 seconds.

[0055] S3. Crush and beat the color-protected Pueraria lobata root, add 0.6% cellulase based on the mass percentage of the processed Pueraria lobata root, treat it wi...

Abstract

The invention discloses a processing method of radix puerariae powder rich in resistant starch, and relates to the field of processing of radix puerariae. The method comprises the following steps of thoroughly cleaning the fresh radix puerariae, removing skin, scrapping and removing black skin, and performing color protection treatment for 120-240 minutes; performing crushing and mashing, adding acellulases solution which is 0.2-1.0% by weight of the processed radix puerariae, performing ultrasound treatment under the power of 400W for 15 minutes, performing homogenization treatment for 20-60minutes with a colloid mill, filtering obtained radix puerariae slurry, and collecting filtrate and filter residues, which are obtained through filtering; preparing an enzyme solution containing cellulases which is 0.5-1.2% by mass of the processed radix puerariae and amylases, adding the enzyme solution to the filter residues, performing homogenization treatment for 30-60 minutes with the colloid mill, performing filtering, and merging the filtrate and the filtrate obtained in the step S3; and performing concentration on the merged filtrate, performing spray drying and performing crushing toobtain finished products of the radix puerariae powder. The processing method of the radix puerariae powder rich in resistant starch can promote the decomposition and the release of dietary fibers and part of granular starch in radix puerariae, and can increase the powder yield of the resistant starch in the radix puerariae powder.

Description

Technical field [0001] The invention relates to the processing field of kudzu root, in particular to kudzu root powder rich in resistant starch and a processing method thereof. Background technique [0002] Pueraria lobata root contains 12% of flavonoids, such as puerarin, daidzein, peanut, and other nutrients, as well as protein, amino acids, sugar, and essential minerals such as iron, calcium, copper, and selenium. Yi's valuable tonic. At present, the processing method of kudzu root powder is usually carried out by the wet method. This method cleans, peels, crushes and beats, filters, washes, repeatedly filters and washes the fresh kudzu root, settles for the separation of slag and slurry, and removes sand, dehydration, and drying. After sieving and packaging, the finished product is obtained. [0003] The above method has the following problems: [0004] 1. Due to the repeated filtering and washing of the pulp in the above processing method, a large amount of water is used, and...
