A kind of maca extract and preparation method thereof

Abstract

The invention discloses a maca extract and a preparation method thereof. The maca extract is prepared by circularly extracting, purifying, concentrating and drying maca serving as a raw material, and comprises 30-40 percent of fatty acid, 18-25 percent of benzyl isothiocyanate and 13-20 percent of macamides and macaenes. The method comprises the following steps of: selecting non-rotten and non-moldy maca which is free from visible external impurities, and finely smashing dried root of maca, wherein the smashing particle size is that the smashed root can pass through a sieve of 60-100 meshes; putting the smashed raw material into an extracting tank, adding 7-9 times of a 50-90 percent alcohol solution, and circularly extracting at the temperature of 45-55 DEG C for 2-5 hours to obtain an extracting solution; putting the extracting solution into a depositing tank for naturally depositing for 6-10 hours, performing suction filtration on a supernatant in vacuum, and centrifuging a filtrate with a high-speed centrifuger at the revolving speed of 10,000-40,000 revolutions per minute; and concentrating a centrifugate in vacuum at the temperature of 40-55 DEG C till the relative density is 1.0-1.3, and drying at the temperature of 40-55 DEG C to obtain a maca extract. The extracting rate of the maca extract is increased greatly, the product purity is increased, and the activity is high.

Description

technical field [0001] The invention belongs to the technical field of extraction of natural plant components, and in particular relates to a high-purity arganum with high extraction rate, which can avoid the pollution caused by traditional precipitants, ensure that the active components are not destroyed, and have the original color, taste and smell of the product. Preparation method of coffee extract. Background technique [0002] Maca, also known as Peruvianginseng, maka, maca-maca, maino, ayakchichira, ayakwillku, etc., is native to the South American Andes at an altitude of 3500-4500 meters, and is now mainly distributed in the Puao ecological zone in central Peru and southeastern Peru. The city of Puno is a plant of the genus Lepidium in the family Cruciferac. Maca gained widespread attention in the early 1990s, when researchers were looking for a substitute for "Viagra" and found that it had a significant effect on improving sexual function, making Maca a new star in...

AI Technical Summary

Problems solved by technology

At present, there are maca health products on the market in my country, but the natural active ingredients of maca have not been extracted, separated and purified, and the efficacy is not obvious. Its health care function needs to be further improved and improved

Existing extraction techniques for maca all have low extraction rate and low purity. Therefore, it is necessary to develop an extraction process with high extraction rate and high purity of maca.
