Natural Gefen Health Food Processing
Gegen is a rare natural wild plant. Pueraria lobata has a starch content as high as 40%. It is rich in 13 essential amino acids and trace elements such as iron, calcium, selenium, zinc, barium, etc. It also contains flavonoids such as soybean pupa and puerarin. Substances, with clear heart and eyesight, heat detoxification, lower blood pressure, anti-cancer and other effects. Domestic and foreign markets are in great demand, with large capacity and high value. Our country's Pueraria is rich in resources, and it has great potential for the development of series of health foods and has a vast market. Now we will introduce the extraction and production technology of natural Pueraria powder as follows for developers' reference. First, timely extraction and extraction of natural arrowroot to grasp the season, usually after the beginning of winter to Qingming. That is, from the late November of that year to March of the following year, it is better to excavate Pueraria radix 2 to 4 years old. Pueraria at an age only contains 10% of starch, which is of low utility value and should not be excavated to protect wild resources. Ginger is a perennial leguminous vine creeping plant. After winter, the vine leaves on the ground are transferred to the underground rhizome for storage and the highest starch content. The pueraria root should be extracted within 3 to 5 days as soon as possible to avoid affecting the quality of mold and starch transformation and decomposition, resulting in decreased powder yield. Second, clean the scrape skin will be excavated from the wild Pueraria, with a knife to cut rattan, tail, lateral roots and damaged parts, put it in clean water for 1 to 2 hours, wash debris after debris picked up, and then use Knife scrape except skin, then rinse with water, pick up the filter dry water. Third, the refining filter will be washed Pueraria pulp with a pulp mill, or cut into 10 centimeters in diameter, about 5 cm in diameter of the root section, into the pulper pulp, broken edge and add water. Then add proper amount of water to the slurry and dilute it. Stir it evenly and filter it with a 80-mesh steel mesh sieve. Refill the filter bag and put it into a tank filled with clean water and rub it again to wash it off. Then use a gauze to filter the slurry in the tank once; or pour into the bottom with a piston and hold most of the barrel Clear special vats are filtered to remove slag. IV. The slurries after sedimentation and sieving should be promptly put into sedimentation tanks or water tanks, and trace alum solution should be added. Stir in the same direction with a clean bamboo stick and stir uniformly to accelerate precipitation and sink impurities to the bottom. After sedimentation, the upper aqueous solution was drained off and the upper yellow slurry (capable of extracting pueraria flavonoids) was separated. After adding appropriate amount of fresh water and stirring, the mixture is allowed to stand for 12 hours, and the upper layer of water is drained. The wet kudzu powder is covered with 3 to 4 layers of white cloth to dry the remaining water. 5. After drying and moisture absorption, remove the white cloth. The upper layer of yellow powder is separated with a spatula (it can be used as a raw material for food without separation), and the yellow powder slurry separated from the sediment is dried together for use. Then remove the wet powder in the sedimentation tank or cylinder, remove the bottom layer of froth, then send the pure Pueraria powder to the drying room to dry at a temperature of 55-65°C, or dry it in an electric oven or microwave oven; or place it in a clean bamboo. Pan or sun mat, drying in a sunny, non-polluting place, natural cooling for 24 hours, the moisture content should be less than 3%, then broken into fine powder, over 100 mesh sieve, that is, silver white pure natural arrowroot for food Or for health food ingredients.
