Embodiment 1

[0027] The defatted soybean meal with protein content of 46-51%, total sugar content of 34.4-38%, fat content of 4-5%, and purine content of 253-275 mg / 100g is pulverized and passed through a 120-mesh sieve, and the sieved defatted soybean meal powder is After mixing with water at a mass ratio of 1:12, ultrasonic treatment was performed. The ultrasonic treatment conditions were ultrasonic temperature 40°C, ultrasonic time 35 min, and then chitosan was added for nucleic acid adsorption. The amount of chitosan added was the total mass of defatted soybean meal aqueous solution 1.0%, the best adsorption time is 100 min, centrifuge at 3000r / min for 5min, filter out the chitosan that adsorbs nucleic acid, and cook the pulp. The cooking conditions are 85°C and 9min. Spray-dried under the conditions of air inlet temperature 80°C and outlet air temperature 175°C, the obtained purine content was 130 mg / 100g, and the protein, total sugar and fat contents were 54%, 27%, and 1% respectively...

Embodiment 2

[0029]The defatted soybean meal with protein content of 46-51%, total sugar content of 34.4-38%, fat content of 4-5%, and purine content of 253-275 mg / 100g is pulverized and passed through a 120-mesh sieve, and the sieved defatted soybean meal powder is After mixing with water at a mass ratio of 1:14, perform ultrasonic treatment. The ultrasonic treatment conditions are ultrasonic temperature 45 ° C, ultrasonic time 40 min, and then add chitosan for nucleic acid adsorption. The amount of chitosan added is 1.5% of the total mass of the defatted soybean meal aqueous solution. %, the best adsorption time is 110 min, centrifuge at 3000r / min for 5min, filter out the chitosan that adsorbs nucleic acid, and cook the pulp. Spray drying under the condition of air inlet temperature 85℃ and outlet temperature 180℃, the content of purine is 125mg / 100g, the content of protein, total sugar and fat are 54.5%, 26% and 0.5% respectively, which meets the requirements of high nutrition and low fa...

Embodiment 3

[0031] The defatted soybean meal with protein content of 46-51%, total sugar content of 34.4-38%, fat content of 4-5%, and purine content of 253-275 mg / 100g is pulverized and passed through a 120-mesh sieve, and the sieved defatted soybean meal powder is After mixing with water at a mass ratio of 1:14, ultrasonic treatment was performed. The ultrasonic treatment conditions were ultrasonic temperature 50°C, ultrasonic time 45 min, and then chitosan was added for nucleic acid adsorption. The amount of chitosan added was the total mass of defatted soybean meal aqueous 2.0%, the best adsorption time is 120 min, centrifuge at 3000r / min for 5min, filter out the chitosan that adsorbs nucleic acid, and cook the pulp. Spray drying under the conditions of inlet air temperature 80-90°C and outlet air temperature 175-185°C, and spray drying under the conditions of inlet air temperature 90°C and outlet air temperature 180°C, the obtained purine content is 124.5mg / 100g, protein , total suga...

Abstract

The invention relates to a method for producing low-purine degreased lactone Tofu. The method comprises the following steps of: 1, pulverizing degreased bean pulps with 46-51 percent of protein, 34.4-38 percent of total sugar, 4-5 percent of fat and 253-275mg / 100g of purine; screening the degreased bean pulps to 120 meshes; and performing ultrasonic treatment on the degreased bean pulps and the water in a mass ratio of (1:12)-(1:16); 2, adding chitosan into the degreased bean pulp aqueous solution subjected to ultrasonic treatment for adsorbing nucleic acid; 3, filtering out the chitosan on which the nucleic acid is adsorbed to prepare low-purine degreased soya-bean milk; 4, boiling the low-purine degreased soya-bean milk and cooling the boiled low-purine degreased soya-bean milk; 5 carrying out spray drying on the low-purine degreased soya-bean milk at the air inlet temperature of 80-90 DEG C and the air outlet temperature of 175-185 DEG C to prepare convenient low-purine degreased Tofu powder; and 6, making Tofu, mixing the convenient low-purine degreased convenient Tofu powder with water in a mass ratio of (1:12)-(1:16), and adding glucose lactone into the mixture to make the Tofu. The low-purine degreased Tofu prepared by the method is suitable for gout patients to orally take, and belongs to the low-purine food.

Description

1. Technical field [0001] The invention relates to a method for preparing tofu, in particular to a method for producing low-purine defatted lactone tofu. 2. Background technology [0002] Hyperuricemia (Hyperuricemia, HuA) and gout (Gout) are a common disease caused by purine metabolism disorder leading to decreased uric acid excretion and / or purine metabolism disorder leading to increased blood uric acid. According to statistics: 90% of gout patients will cause impotence, nephritis, stones and other chronic kidney disease and heart disease and other complications; 50% of patients are prone to severe deformation of joints and become disabled; Diseases such as exhaustion lead to death. Clinically, the goal of treatment is to prevent the onset of acute gouty arthritis, protect the kidneys, and eliminate tophi. The treatment method is to inhibit the formation of uric acid (UA) and accelerate the excretion of uric acid from the body. Traditional anti-gout drug therapy has a c...
