Embodiment 1

[0030] A method for extracting selenium cordyceps essence, characterized in that, by the following extraction steps:

[0031] a. Drying treatment of Cordyceps selenium: drying the secondary Cordyceps selenium and its fungus turf so that the water content is less than 6%;

[0032] b. Pulverization: Use a pulverizer to pulverize to 40-50 mesh, so as to increase the extraction surface area and extract more nutrients from Selenium Cordyceps;

[0033] c. Reflux extraction: add deionized water to make "glycine-HCl buffer solution" with pH = 3.2-4.5, assisted ultrasonic reflux extraction at 60°C for 90 minutes, centrifuged in a tubular centrifuge, and then used 30%-40% ethanol to assist ultrasonic 50 Reflux and extract at ℃ for 60 minutes, centrifuge; combine the two filtrates, concentrate under reduced pressure at 60℃ to 60%;

[0034] d. Spray drying: spray drying conditions are inlet temperature 136°C, outlet temperature 67°C, wind speed 44.18 rpm, electric spray head speed 4000 r...

Embodiment 2

[0039] A method for extracting selenium cordyceps essence, characterized in that, by the following extraction steps:

[0040] a. Drying treatment of Cordyceps selenium: drying the secondary Cordyceps selenium and its fungus turf at 60-80°C to make the water content less than 6%;

[0041] b. Pulverization: use Shanghai Ruiyuan Machinery Equipment Co., Ltd., model RY-NSG-100L-C pulverizer to pulverize and sieve 3000g of selenium cordyceps powder to 50 mesh, and put it into an ultrasonic extraction tank;

Abstract

The invention provides a method for extracting essence of selenium-enriched cordyceps. The invention is characterized in that the method comprises the following extraction steps: a. drying treatment of selenium-enriched cordyceps; b. crushing; c. reflux extraction; d. spray drying; e. vacuum package. A solvent-aided supersonic wave two-step heat reflux extraction method is used, so that active ingredients in the selenium-enriched cordyceps are extracted fully, and the recovery rate of selenium reaches above 90%; extraction time of the solvent-aided supersonic wave two-step heat reflux extraction method is optimized, and compared with the traditional method, extraction time is reduced by more than 2 / 3; the extraction temperature is below 60 DEG C, active ingredients which are heat-labile and easy to hydrolyze or oxidize in the medicinal material are protected, and energy consumption is substantially saved.

Description

technical field [0001] The invention relates to a method for extracting selenium cordyceps essence. Background technique [0002] Cordyceps contains cordycepin, cordycepic acid, polysaccharides, more than 10 kinds of amino acids and various trace elements. Modern medical and nutritional studies have shown that Cordyceps can regulate the immune system and blood system, protect and prevent kidney, liver, and heart damage, and have anti-aging, anti-stress, and anti-tumor effects. However, due to strict parasitism and special growth geographical environment restrictions, drug sources are in short supply and expensive, which is far from meeting the market demand. Selenium is an essential trace element for the human body. Modern medical research shows that selenium deficiency is related to the occurrence of more than 40 diseases such as Keshan disease, Kaschin-Beck disease, cardiovascular and cerebrovascular diseases, and cancer. Selenium supplementation can effectively reduce t...
