Method for extracting active ingredients from maca

Abstract

The invention relates to a method for extracting active ingredients from maca. The method comprises the following steps: pulverizing: performing super-micro pulverizing and wall-breaking treatment on a maca raw material to obtain maca wall-broken super-micro powder; deactivating enzyme: performing lighting enzyme deactivation pretreatment on the obtained wall-broken super-micro powder by adopting pulse intense light; flash extracting: mixing the obtained wall-broken super-micro powder and absolute ethyl alcohol for dissolving, extracting the mixture into a flash-type extractor, and after the extraction, filtering to obtain extract liquid; and freeze drying: freeze drying the obtained extract liquid in an environment at the temperature of 20 DEG C or lower, thus obtaining the maca extract rich in the active ingredients. The method has the following beneficial effects: (1) the flash-type extraction can maximally keep the active ingredients of the plant, the active ingredients are not damaged by heating, less solvent is used, the extraction time is short, the efficiency is high, a cutter is abrasion-proof, the structure is compact, and the use is safe and reliable; and (2) myrosinase is deactivated by adopting the pulse intense light method, so that partial loss of the functional ingredients of a product is avoided , and the content of the functional ingredients is increased.

Description

technical field [0001] The invention relates to an extraction method, in particular to an extraction method of effective components in Maca, and belongs to the technical field of natural product extraction. Background technique [0002] Maca, which is widely used on the Peruvian plateau, has high nutritional value, and its functional ingredients such as maca alkaloids, glucosinolates, macamides and sterols can improve fertility, promote libido, adaptogenicity, and promote hormone metabolism Synthetic and other physiological effects, Maca has been widely cultivated in Peru for thousands of years, has rich nutrients, and is one of the main food sources for local residents. With the in-depth research on maca, it has gradually become a hotspot in the research of medicinal and edible homologous plants in the world. Only in the United States and Japan in 2002, the sales volume of Maca has exceeded 2 billion US dollars. In 2007, the global sales volume has reached 5 billion yuan, ...

AI Technical Summary

Problems solved by technology

[0003] Traditional maca extraction methods such as decoction method, reflux method, continuous reflux method, maceration method, countercurrent method, ultrasonic extraction, microwave extraction, etc. have been well known, and the extraction time of traditional methods is too long, ranging from 1 hour to longer , and the operation is repeated, resulting in low production efficiency, long production cycle, high production cost, high energy consumption, low yield, and some heating methods are easy to destroy the original active ingredients, so it is not suitable for large-scale production

In the past maca extraction process research, for the inactivation of myrosinase in maca, methods such as microwave radiation and high-temperature steam were often used, and these methods would cause partial loss of product functional components and affect the efficacy of maca
