Embodiment 1

[0021] After the dried kudzu root was crushed, the raw kudzu powder was adjusted to a 15% uniform emulsion with distilled water. After adjusting the milk, the pH was adjusted to 5.0, and 1500 U / g of fungal α-amylase was added, and stirred in a constant temperature water bath at 50°C for 2 hours. After the enzymolysis, the enzyme was boiled in boiling water for 5 minutes, cooled to room temperature, centrifuged at 3000 r / min, and dried to obtain the solid substance of kudzu powder.

Embodiment 2

[0023] After taking the dried kudzu root and crushing it, the raw kudzu powder was adjusted into a 15% uniform emulsion with distilled water. After adjusting the milk, the pH was adjusted to 4.5, 13 U / g of pullulanase was added, and stirred in a constant temperature water bath at 60°C for 3 hours. After the enzymolysis, the enzyme was boiled in boiling water for 5 minutes, cooled to room temperature, centrifuged at 3000 r / min, and dried to obtain the solid substance of kudzu powder.

Embodiment 3

[0025] After taking the dried kudzu root and breaking it, adjust the raw kudzu powder into a 15% uniform emulsion with distilled water, adjust the pH to 4.8 after adjusting the milk, and add 1500U / g of fungal α-amylase and 13U / g of pullulanase at the same time, Stir in a constant temperature water bath at 60°C for 3h. After the enzymolysis, the enzyme was boiled in boiling water for 5 minutes, cooled to room temperature, centrifuged at 3000 r / min, and dried to obtain the solid substance of kudzu powder.

Abstract

The invention belongs to the field of the deep processing of Radix Puerariae, and discloses a method for preparing instant Radix Puerariae powder through adopting a compound enzyme. The method comprises the followings steps: grinding Radix Puerariae to form powdery Radix Puerariae, adding water to the powdery Radix Puerariae, stirring for slurry mixing to obtain a slurry having a concentration of 15%, adding assistants, adjusting the pH value to 4-5, adding the compound having an amount being 1.5-2% of the powdery Radix Puerariaer, carrying out stirring enzymatic hydrolysis at a constant temperature for 3h, carrying out boiling inactivation for 5min, cooling, centrifuging, and drying to obtain a solid substance of the powdery Radix Puerariae. The prepared Radix Puerariae powder has the advantages of good mouthfeel, good dissolubility, convenient eating, and effective reservation of various nutrition and other effective components of Radix Puerariae, is a convenient environmentally-friendly healthcare food, and can be developed and popularized as a novel instant Radix Puerariae beverage.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a method for preparing instant kudzu powder by using a compound enzyme method. Background technique [0002] Puerarin has always been known as "Southern Gegenseng and Northern Ginseng" and "Southern Ginseng", which has great nutritional and medicinal value. Kudzu root is rich in nutrients such as starch, flavonoids, amino acids, dietary fiber, and trace elements that are beneficial to the human body. Various studies have shown that it has various health functions such as weight loss and beauty, delaying aging, lowering blood sugar, lowering blood fat, improving osteoporosis, improving memory, removing garbage in the body, and enhancing immunity. Therefore, kudzu powder is also known as "longevity powder". It has strong demand, large capacity and high value in domestic and foreign markets. [0003] Pueraria lobata is a common traditional Chinese medicine. It is a resourc...
