Embodiment 1

[0022] 1) Place 2 g of pearl powder and 10 g of pure water A obtained from the commercially available (Zhejiang Osman Group Deqing Biotechnology Co., Ltd.) Microwave power 200W, reaction time 1h, obtain reaction solution A; 2) add 10g pure water B to step 1) reaction solution A, obtain reaction solution B, the total amount of water A and water B added is 10 times of the pearl powder feeding amount, Keep the temperature of the system at 60°C and react for 3 hours with intermittent gradient heating, that is, react at 60°C for 30 minutes, stop for 10 minutes, react for another 30 minutes, stop for 15 minutes, react for another 30 minutes, stop for 20 minutes, react for another 30 minutes, stop for 25 minutes, and then react for 30 minutes , stop for 30 minutes, react for another 30 minutes, and the reaction ends.

[0023] Reacted for 3h, after the reaction was finished, the reactor was cooled, the reaction liquid B was filtered, and the filter cake was vacuum-dried to constant we...

Abstract

The invention discloses a microwave-hydrolyzation method of pearl powder. The method comprises the steps of: (1) carrying out freeze drying on raw pearl powder for pre-activation, mixing the pearl powder subjected to freeze drying with water A to prepare turbid liquid, transferring the turbid liquid into a microwave reactor, controlling the temperature at 60-200 DEG C, the microwave power at 100-300 W, and the pressure at 200 Pa, and reacting for 0.5-5 hours to obtain reaction liquid A; and (2) adding water B to the reaction liquid A prepared in step (1) again to obtain reaction liquid B, keeping the system at the constant temperature of 60-200 DEG C, reacting for 0.5-10 hours in an intermittent gradient heating way and filtering the reaction liquid B after the reaction is ended so as to obtain a product of the pearl powder, wherein the total addition amount of the water A and the water B is 10 to 40 times of the amount of added pearl powder. According to the microwave-hydrolyzation method of the pearl powder, disclosed by the invention, numerous adverse factors of the conventional hydrolyzation method of pearl powder, such as complex separation process (acid, alkaline, enzyme catalyst and the like), environmental pollution caused by the posttreatment process, low utilization rate and the like are eliminated; moreover, the whole process is carried out without any factors bad for health, and therefore the pure natural property of nutrient components of the pearl (pearl powder) can be ensured.

Description

(1) Technical field [0001] The invention relates to a hydrolysis method of pearl powder, in particular to a microwave hydrolysis method of pearl powder. (2) Background technology [0002] The medicinal use of pearls has a history of more than 2,000 years in China. Various ancient medical books have clear records of the curative effect of pearls. Modern medical research has proved that pearls contain 19 kinds of amino acids, nearly 20 kinds of minerals and highly active biological taurine, rich in pearl protein and a large number of trace elements, which can improve the body's anti-aging factor SOD and amino acid carrier GSH-PX It has the functions of calming the nerves, clearing away heat and detoxification, soothing the liver and protecting the liver, regulating the stomach, supplementing calcium, and supplementing trace elements; at the same time, it can delay skin aging, remove freckles, acne, and wrinkle, and enhance skin luster and elasticity; through regulating Human...
