Kudzuvine root powder processing method

Abstract

The invention relates to a kudzuvine root processing method which is characterized by comprising the following steps: a, crushing the raw materials, namely flushing the fresh kudzuvine root by using water to remove silt, and crushing; b, pulping and separating, namely crushing the fresh kudzuvine root, performing centrifugal separation, and collecting the pulp and kudzuvine residue, so that the pulp and the residue are separated; c, refining, collecting the pulp after the pulp and the residue are separated, adding a potentilla fulgens wall extracting solution, standing, realizing powder and silt separation, and collecting the powder-containing pulp, wherein the potentilla fulgens wall extracting solution is an extracting solution through centrifugal collection after the potentilla fulgens wall is crushed; and d, drying, namely standing the pulp in which the silt and impurities are removed, collecting the precipitate, and drying to obtain the finished product. According to the kudzuvine root processing method, a method for removing silt, small particle kudzuvine root residue and other impurities in pulp by utilizing white alum and other chemical substances in the traditional process is abandoned, a small amount of Chinese herbal medicine potentilla fulgens wall extracting solution is added, and the density distribution of the pulp is changed; and moreover, the kudzuvine root powder, silt and impurities in the pulp are separated at high efficiency, the kudzuvine root powder is high in recovery rate, and the nutrient substances in the kudzuvine root powder are enriched.

Description

[0001] The invention relates to a processing method of kudzu powder. Background technique

[0002] Pueraria lobata is the root of the Pueraria genus of the leguminous family, also known as Gange, Pueraria vine, and Gange, etc. It is the first batch of medicinal and edible plants approved by the Ministry of Health. According to the survey, there are about 20 species of Pueraria plants in the world, among which there are 11 species in my country, which are mainly distributed in temperate and subtropical regions. Among them, Pueraria lobata and Pueraria lobata are widely distributed and have high yields. They are varieties with more resources, and they are also processed, utilized and eaten. main species. The main components of kudzu root are starch, dietary fiber, flavonoids, protein and a small amount of vitamins and minerals, etc. The contents of starch, flavonoids and dietary fiber in different varieties of kudzu root are different, and the content of starch...

Embodiment 1

[0021] Embodiment 1: the concrete steps of the processing method of a kind of kudzu powder of the present invention are as follows:

[0022] (1) Pre-treatment of kudzu root, including raw material cleaning, crushing, rotary washing and separation of pulp and slag: fresh kudzu root is cleaned to remove sediment, cut into 2-3cm thick slices, and then crushed by a universal grinder, and the crushed pulp and slag are sent to In a 3.3m-long horizontal rotating bucket, wash and centrifuge with tap water until there is no starch in the slurry, and collect kudzu slag and slurry respectively. The flow rate of tap water was adjusted according to the residual starch in the kudzu slag, and the final mass ratio of kudzu slurry to fresh kudzu root was about 1.5:1.

[0023] (2) Separation of silt and sand in the slurry: after the separation of slurry and slag, collect the slurry, add Guanzhong extract at a volume ratio of 100-200:1, and after 15-30 minutes, the small particles of kudzu slag ...

Embodiment 2

[0026] Embodiment 2: the specific steps of the processing method of a kind of kudzu powder of the present invention are as follows: a. raw material pulverization: fresh kudzu root is rinsed away silt with tap water, is cut into 2~3cm thick flakes, pulverizes through universal pulverizer;

[0027] b. Separation of pulping: fresh kudzu root is crushed and sent to a horizontal rotating bucket, washed by tap water and centrifuged until there is no starch in the slurry, and the slurry and kudzu slag are collected to realize the separation of pulp and dregs. The final mass ratio of slurry to fresh kudzu root is 1.5 :1;

[0028] c. Refining: After separating the pulp and slag, collect the slurry, add Guanzhong extract at a volume ratio of 100-200:1, and let it stand for 15-30 minutes. The silt in the slurry and small particles of kudzu slag aggregate and sink, and the slurry containing kudzu powder rises. Realize the separation of silt and sand, and collect the powder-containing slur...
