Embodiment 1

[0011] Embodiment 1: A method for preparing Pueraria mirifica starch rich in flavonoids, comprising the following steps: a. Cleaning: Fresh Pueraria mirifica is washed with tap water until there is no mud, and placed in a clean place until there is no surface water drop; b. Slicing: Along the Cut the cross-section into 2-3cm thick slices; c. beating: beat the cut kudzu slices; d. filter: soak in 60% ethanol for 4 hours, and filter with a 100-mesh filter; e. settling: let the filtrate Settling for 10 hours; f. Concentration: extract the upper layer and concentrate to one-fifteenth of the original volume, and combine the concentrated solution with the lower layer of starch solution; g. Drying: place the combined solution at 40°C for 48 hours to air-dry, and then place it for 60 8 hours in a drying oven at ℃; h. Packaging: Cool for 6 hours at room temperature, seal the package and place it in a low-temperature sterile place. The step f. Concentration: Concentration conditions of ...

Embodiment 2

[0012] Embodiment 2: a kind of preparation method of Pueraria mirifica starch with high flavonoid content,

[0013] Weigh 5 kg of fresh Pueraria mirifica, wash it with tap water until there is no mud, and place it in a clean place until there is no surface water dripping. Cut into 2-3cm thick slices along the cross section of Pueraria mirificatus. Beat the cut kudzu slices. Soak in 60% ethanol for 4 hours, and filter with a 100-mesh filter. Allow the filtrate to settle for 10 hours, extract the supernatant and concentrate to one-fifteenth of the original volume, combine the concentrated solution with the body starch solution, place it at 40°C for 48 hours to air-dry, and then place it in a 60°C drying oven for 8 hours. At normal temperature, cool the kudzu starch in the above 5 for 6 hours, weigh 313 grams of starch, and have a total flavonoid content of 2.7%. Store in a low-temperature sterile place after sealing the package.

Embodiment 3

[0014] Embodiment 3: a kind of preparation method of Pueraria mirifica starch with high flavonoid content,

[0015] Weigh 50 kg of fresh Pueraria mirifica, wash it with tap water until there is no mud, and place it in a clean place until there is no surface water dripping. Cut into 2-3cm thick slices along the cross section of Pueraria mirificatus. Beat the cut kudzu slices. Soak in 60% ethanol for 4.5 hours, and filter with a 100-mesh filter. Allow the filtrate to settle for 10 hours, extract the supernatant and concentrate to one-fifteenth of the original volume, combine the concentrated solution with the body starch solution, place it at 40°C for 48 hours to air-dry, and then place it in a 60°C drying oven for 8 hours. At room temperature, cool the kudzu starch in the above 5 for 6.5 hours, weigh 3527 grams of starch, and have a total flavonoid content of 2.4%. Store in a low-temperature sterile place after sealing the package.

Abstract

The invention relates to a preparation method of flavone-enriched pueraria lobata starch. The preparation method is characterized by comprising the following steps: cleaning, slicing, pulping, filtering, settling, concentration, drying and packaging. The preparation method has the beneficial effects that an ethanol solution is used as an extracting agent, and the total flavone content of the starch is 2.3 to 2.8 percent, namely every 100 grams of starch contain 2.3 to 2.8 grams of flavones; and the total flavone content is nearly 100 times higher than that of the conventional radix puerariae starch. Compared with a conventional radix puerariae starch extraction process, the process is simple.

Description

technical field [0001] The invention relates to a preparation method of Pueraria mirifica starch rich in flavonoids. Background technique [0002] Pueraria lobata (Willd.) Ohwi is a leguminous plant, which belongs to medicinal and edible plants. It is widely distributed in my country. Pueraria lobata (Willd.) Ohwi is rich in Pueraria lobata starch, and Pueraria lobata contains a substance called isoflavones, which can Improvements in some markers of metabolic syndrome, including blood pressure, high cholesterol and blood sugar. The specific isoflavones of puerarin, found only in kudzu, are probably the most beneficial substances. Research shows that puerarin helps lower blood pressure and blood cholesterol. But the biggest effect we found was regulating blood sugar. Both diabetes and obesity will cause blood puerarin to lower blood sugar by rationally distributing glucose, such as putting it in a useful place (muscle) and reducing its distribution in fat cells and blood ve...
