Embodiment 1

[0014] A preparation method of kudzu root powder, comprising the following steps:

[0015] (1) Material selection: select fresh kudzu root with complete appearance, wash with water, drain the water, and set aside;

[0016] (2) Drying: Cut the cleaned kudzu root obtained in step (1) into thin slices with uniform thickness, then place it in a low-temperature constant temperature oven and dry it at 35°C for 14 hours at low temperature, and set aside;

[0017] (3) Pulverization: after pulverizing the dried kudzu root slices prepared in step (2) in a high-efficiency pulverizer, set aside;

[0018] (4) Swelling and puffing: put the pulverized kudzu root obtained in step (3) in an extruder, and after aging and puffing at a temperature of 95°C for 3 hours, put the agglomerated kudzu root powder in a pulverizer to pulverize and Pass through a 85-mesh sieve.

Embodiment 2

[0020] A preparation method of kudzu root powder, comprising the following steps:

[0021] (1) Material selection: select fresh kudzu root with complete appearance, wash with water, drain the water, and set aside;

[0023] (3) Pulverization: after pulverizing the dried kudzu root slices prepared in step (2) in a high-efficiency pulverizer, set aside;

[0024] (4) Swelling and puffing: put the pulverized kudzu root obtained in step (3) in an extruder, and after aging and puffing at a temperature of 97°C for 2.5 hours, put the agglomerated kudzu root powder in a pulverizer to pulverize and Pass through a 90-mesh sieve.

Embodiment 3

[0026] A preparation method of kudzu root powder, comprising the following steps:

[0027] (1) Material selection: select fresh kudzu root with complete appearance, wash with water, drain the water, and set aside;

[0028] (2) Drying: Cut the cleaned kudzu root obtained in step (1) into thin slices with uniform thickness, then place it in a low-temperature constant temperature oven and dry it at 45°C for 12 hours at low temperature, and set aside;

[0029] (3) Pulverization: after pulverizing the dried kudzu root slices prepared in step (2) in a high-efficiency pulverizer, set aside;

[0030] (4) Swelling and puffing: put the pulverized kudzu root obtained in step (3) in an extruder, and after aging and puffing at a temperature of 100°C for 2 hours, put the kudzu root powder agglomerated in the pulverizer into a pulverizer and crush it. Pass through a 95-mesh sieve.

Abstract

The invention discloses a preparation method of kudzu root initial powder, comprising the following steps: (1) material selection: selecting kudzu root, washing and draining the kudzu root; (2) drying: cutting the kudzu root into flakes with uniform thickness, and drying the kudzu root flakes at 35-45 DEG C in a low-temperature constant temperature oven for 12-14 hours; (3) pulverization: pulverizing the kudzu root flakes obtained in the step (2) in a high-efficiency pulverizer; and (4) curing and bulking: curing and bulking the kudzu root pulverized in the step (3) at 95-100 DEG C for 2-3 hours, then pulverizing the kudzu root powder blocks in a pulverizer and sieving the powder with a 85-95 mesh screen. The kudzu root initial powder prepared by the mode of pulverizing and curing after drying at constant temperature is natural in taste and free of nutrient loss, the flavor and characteristics of the original product are reserved to 100% in the product produced by the invention, all nutrient components contained in the original product except mechanical loss are reserved to 100%, and the activities of the nutrient components are ensured to be not changed.

Description

technical field [0001] The invention belongs to the technical field of food, and in particular relates to a preparation method of kudzu root powder. Background technique [0002] The main component of Pueraria lobata is starch, and in addition contains about 12% flavonoids, including more than 10 kinds of daidzein, daidzein, puerarin, etc.; and contains carrotin, amino acids, coumarins, etc.; Protein, amino acid, sugar, and minerals such as iron, calcium, copper, and selenium necessary for the human body are valuable tonics suitable for all ages, and have the reputation of "thousand-year ginseng". As early as Zhang Zhongjing's "Treatise on Febrile Diseases" in the Han Dynasty, there was a famous prescription "Gegen Decoction", which is still an important prescription for treating symptoms. "Materia Medica Justice" said Pueraria lobata root "can best develop the qi of spleen and stomach Qingyang". [0003] Pueraria lobata is sweet and slightly pungent, with a delicate scent...
