Extraction method of effective ingredients in maca

Abstract

The present invention provides an extraction method of effective ingredients in maca. The method is characterized by consisting of the following steps: maca powder at 150-250 meshes and water at a mass ratio of 1:(5-20) are mixed, the mixture is subjected to a high-pressure homogenization, the mixture is sprayed into a vacuum container to be soaked via a high-pressure nozzle, soaking liquid is subjected to a membrane filtration, filtrate is concentrated at a temperature of 10-40 DEG C, 40-50% of water content is removed to obtain extraction liquid containing maca water-soluble effective components, residue and anhydrous ethanol are mixed at a mass ratio of 1:(5-10) evenly, the mixture is soaked for 2-5 hours, the soaking liquid is subjected to the membrane filtration, the filtrate is concentrated at a temperature of 10-40 DEG C, and 70-80% of the ethanol is removed to obtain the extract containing maca lipid-soluble effective components. On the basis of the water extraction, then the lipid extraction is conducted, so that both the water-soluble and lipid-soluble effective components are extracted and the extraction rate of the maca effective components is high. All the technologies are conducted at room temperature to effectively prevent the destructions of the activities of the effective ingredients.

Description

technical field [0001] The invention relates to a method for extracting effective components of maca. Background technique [0002] Maca (scientific name: Lepidium meyenii Walp.), (Spanish: Maca), alias: Maca, is a cruciferous plant of the genus Lepidium, native to the Andes of South America. It has the functions of anti-fatigue, anti-oxidation, enhancing immunity, improving sexual function, regulating endocrine, and improving fertility. It is one of the safe foods recommended by the United Nations Food and Agriculture Organization. In 2011, the Ministry of Health of my country approved maca as a new resource food ( Ministry of Health Announcement No. 13 of 2011). [0003] The above-mentioned health benefits of maca are related to the components such as macaene, maca amide, maca polysaccharide, glucosinolate and its derivatives. At present, the extraction methods for the active ingredients of Majia are as follows: one is to extract under normal temperature conditions, which...

AI Technical Summary

Problems solved by technology

At present, the extraction methods of active ingredients of maga are as follows: one is extraction under normal temperature conditions, which takes a long time to extract and the extraction rate is low; the other is extraction under high temperature conditions. The structure will be destroyed under the action, and the activity will be lost; the third is single solvent extraction, Maca has both water-soluble components and fat-soluble components, and a single solvent can not completely extract the functional components, resulting in waste of resources
