Abstract

The present invention relates to a production method of using malt root powder to prepare low-purine defatted soybean powder. The production method of using malt root powder to prepare low-purine defatted soybean powder is as follows: defatted soybean meal is pulverized, and the mass ratio of defatted soybean meal to water is 1 :6‑1:12 after mixing, the pH is 5.2, stirring, and then ultrasonic treatment, then adding 1.0%‑2.5% of malt root powder to the total mass of defatted soybean meal powder and water, and then adding Ca 2+ , Mg 2+ Carry out water-bath treatment; add chitosan to the degreasing soybean meal aqueous solution after above-mentioned water-bath treatment and carry out the adsorption of nucleic acid, the addition amount of chitosan is 0.5%-2.5% of the total mass of the solution after ultrasonic treatment, and the adsorption time is 70-140 min; The low-purine defatted soybean milk is obtained by centrifugation; the low-purine defatted soybean milk is spray-dried to obtain the low-purine defatted soybean powder, and the purine content in the low-purine defatted soybean powder is 100-140 mg / 100g. The invention is used to solve the problem that the current defatted soybean meal is processed into soybean protein powder with relatively high purine content.

Description

[0001] 1. Technical field [0002] The invention relates to a preparation method of soybean flour, in particular to a production method of utilizing malt root powder to prepare low-purine defatted soybean flour. [0003] 2. Background technology [0004] Due to the disorder of purine metabolism, the excretion of uric acid is reduced, resulting in the deposition of uric acid in the form of urate crystals in the joints, thereby causing the occurrence of gout inflammation. According to statistics, the number of patients with hyperuricemia in my country has reached 120 million, of which more than 75 million are patients with gout, and they are increasing rapidly at a growth rate of 9.7% every year. The second largest metabolic disease after diabetes. The onset of gout is related to the daily intake of foods rich in purines, such as meat and seafood. The main reason is that animal foods will increase the serum uric acid content and aggravate the disease, which greatly reduces the hi...
