Embodiment Construction

[0013] Grind the dry maca powder and mix it with distilled water, choose the ratio of solid to liquid as 1:60 (g / ml), and put it in the stirring tank for initial stirring;

[0014] The feed liquid that has been stirred initially is poured into a sealed microwave-ultrasonic composite stirring container for stirring, and the ultrasonic wave with a frequency band of 40KHz is selected, and the ultrasonic power is 300W; the microwave frequency is 300MHz, and the microwave power is 352W. Stirring time is 30min, work at room temperature.

[0015] The feed liquid after stirring is now filtered, and the obtained residue is rinsed twice with distilled water, and the obtained washing liquid is combined into the filtrate, and then concentrated to obtain an extract. Dissolve the extract with 2% HCl, adjust the pH to 9-10 with concentrated ammonia water, then extract with chloroform three times to obtain the extract, and finally concentrate the extract by airtight evaporation to obtain the ...

Abstract

The invention discloses a method for extracting maca alkaloids through microwave and ultrasonic wave combination. The process comprises the main steps: grinding raw materials, mixing and dissolving, controlling the parameters, stirring through microwave and ultrasonic wave combination, filtering, and extracting. The method comprises the following sub-steps: mixing and dissolving the maca powder according to a material-liquid ratio of 1:60, preliminarily stirring the raw materials and distilled water in a stirrer, transferring the mixture into a built-in ultrasonic extraction tank, operating at normal temperature, and selecting ultrasonic waves in the wave band at the frequency of 40KHz, wherein the power of the ultrasonic wave is 300 W, the selected ultrasonic wave frequency is 300MHz, the microwave power is 352 W, and the stirring time is 30 minutes; evaporating and concentrating the extracting solution subjected to filtration, concentration, pH regulation and extraction so as to obtain the extract of the maca alkaloids.

Description

technical field [0001] The invention relates to a method for compoundly extracting maca alkaloids with microwave and ultrasonic waves. The method can quickly and efficiently extract the alkaloids in maca, and improves the extraction rate of maca alkaloids. Background technique [0002] Maca (Maca), an annual or biennial herb of the Brassicaceae genus, is native to the Andes in central Peru, South America, and has been eaten locally for thousands of years. Maca is rich in nutrients such as carbohydrates, proteins, minerals, and vitamins. As a dual-purpose plant for medicine and food, the secondary metabolites alkaloids and glucosinolates of maca have functions such as improving sexual function, increasing fertility, anti-fatigue, anti-tumor, anti-anxiety and improving endocrine. This makes Maca a hot spot in functional food research both at home and abroad. In recent years, products using maca as a dietary supplement have become popular in the European, American and Japanes...
