Problems solved by technology

[0008] It can be seen from the above process that the production of kudzu powder is mainly to extract the starch in the kudzu root, but a large amount of flavonoids and polysaccharides and other substances with higher value are retained in the waste water and waste residue, resulting in kudzu root in the kudzu powder product. The isoflavone content of kudzu root such as Su is very little, and the utilization of kudzu root cannot be effectively realized.

Embodiment 1

[0051] Take 1 kg of fresh kudzu, remove the rotten part, clean it, chop it up, use about 8 kg of water, squeeze and crush it, add water to wash the powder, filter, put the slurry into the settling tank, settle for 12 hours, separate the mother liquor, and remove sand Rinse the sedimented starch 3 times with about 3 kilograms of water in total, settle for 3 hours after each rinsing, take out the wet starch and control the temperature at 70-80 ° C for 4 hours in vacuum to get 190 grams of kudzu starch. During the above process, 12 kg of waste water (mother liquor and rinsing liquid) and some fibrous waste residue (about 0.2-0.3 kg) are produced.

Embodiment 2

[0053] The fibrous waste slag obtained in Example 1 was added to a 20L jacketed glass kettle with stirring, and all 12 kg of waste water was added. Under stirring, the jacketed hot water was heated to a temperature of 50°C in the kettle, and kept for leaching for 1 hour. Filtrate while hot to obtain filtrate and fiber slag, rinse and dry the fiber slag with about 1 kg of water for later use, combine the filtrate and lotion, and pump to two-stage microfiltration membrane (double-layer microporous membrane filter) for filtration to obtain Microfiltrate (the pore diameter of the primary microfiltration membrane is 5 microns, and the pore diameter of the secondary microfiltration membrane is 2 microns), and the microfiltrate is controlled at room temperature at a pressure of 3.0-3.5 MPa into the membrane and a pressure of 2.5-3.0 MPa out of the membrane. Enter the reverse osmosis membrane (reverse osmosis system) for membrane concentration. When the weight of the concentrated solut...

Embodiment 3

[0055] Embodiment three is basically the same as embodiment two, the difference is that the waste water is divided into 3 times (each time 4 kg) to extract fibrous waste residue, finally obtain 32 grams of kudzu root water extract, the puerarin content is 12.5% ​​through HPLC detection, The recovery rate of puerarin was 0.4%.

Abstract

The invention discloses puerarin-rich instant arrowroot and a preparation method thereof, and belongs to the technical field of agricultural product processing. The puerarin-rich instant arrowroot comprises the following ingredients: 80-95 parts by weight of arrowroot starch, 2-20 parts by weight of arrowroot water extract, and 0.01-0.1 part by weight of sucralose. The preparation method comprises the following steps: uniformly mixing a sucralose water solution and the arrowroot starch according to the ratio; adjusting the water content to 11-13%; performing puffing cooking, wherein the puffing temperature is 135-145 DEG C and the puffing speed is 0.5-1 m / min; drying, wherein the drying temperature is 80-90 DEG C and the drying duration is 2-5 h; smashing, and screening with a 80-100 meshed sieve to obtain instant arrowroot starch; uniformly mixing the arrowroot water extract and the instant arrowroot starch according to the ratio; pelletizing through a drying method; smashing, and screening with a 60-80 meshed sieve to obtain puerarin-rich instant arrowroot. The puerarin mass content of the instant arrowroot provided by the embodiment of the invention is larger than 15 mg / g, and the puerarin-rich instant arrowroot has a good taste, and a good appearance, and is good in instant property.

Description

technical field [0001] The invention belongs to the technical field of agricultural product processing, in particular to an instant kudzu powder rich in puerarin and a preparation method thereof. Background technique [0002] Pueraria lobata is widely distributed in my country, rich in resources, rich in starch, dietary fiber, flavonoids, polysaccharides, etc. It has many health functions such as nourishing nutrition, beauty and skin care, anti-oxidation, anti-aging, improving osteoporosis, regulating estrogen level, removing garbage in the body, improving circulation, reducing fat and losing weight, regulating blood pressure, etc. It is even more important for caring for women's youth Particularly important. [0003] At present, puerarin and other pueraria isoflavones in the pueraria powder products sold on the market are very small, especially the water-soluble pueraria polysaccharides with anti-oxidation function basically do not contain, and a large amount of active ing...
