Embodiment 1

[0019] A preparation method of maca extract, characterized in that through the following steps:

[0020] 1) Crush 10 kg of washed maca root into maca powder with particle size less than 1mm;

[0021] 2) Put the maca powder in step 1) into a microwave dryer, heat up to 50°C, keep it for 25 minutes, and cool to room temperature to inactivate the enzyme, destroy the activity of the enzyme, and prevent the hydrolysis of glucosinolate;

[0022] 3) Put the maca powder treated in step 2) into the extraction tank, add ethanol with a mass concentration of 95% in an amount 7 times the mass of the maca powder, soak for 3 hours, and heat up to a liquid temperature of 70°C , reflux extraction for 4 hours, and separate the primary extract and residue; in the primary residue, add ethanol with a mass concentration of 95% of 3 times the mass of maca powder, heat to a liquid temperature of 70°C, and reflux After extracting for 3 hours, separate the secondary extract and residue; in the seconda...

Embodiment 2

[0028] A preparation method of maca extract, characterized in that through the following steps:

[0029] 1) Crush the washed maca stalks into maca powder with a particle size of less than 3mm;

[0030] 2) Put the maca powder in step 1) into a microwave dryer, heat up to 60°C, keep it for 15 minutes, and cool down to room temperature to inactivate the enzyme, destroy the activity of the enzyme, and prevent the hydrolysis of glucosinolate;

[0031]3) Put the maca powder treated in step 2) into an extraction tank, add 9 times the mass of maca powder in ethanol with a mass concentration of 95%, soak for 1 hour, and heat up to a liquid temperature of 85°C , reflux extraction for 2 hours, and separate the primary extract and residue; in the residue, add ethanol with a mass concentration of 95% in an amount 5 times the mass of maca powder, and heat up to a liquid temperature of 85°C, then reflux extraction After 3 hours, separate the secondary extract and residue; add ethanol with a...

Embodiment 3

[0037] A preparation method of maca extract, characterized in that through the following steps:

[0038] 1) Grinding the washed maca leaves into maca powder with particle size less than 2mm;

[0039] 2) Put the maca powder in step 1) into a microwave dryer, heat up to 55°C, keep it for 20 minutes, and cool to room temperature to inactivate the enzyme, destroy the activity of the enzyme, and prevent the hydrolysis of glucosinolate;

Abstract

The invention provides a preparation method of a maca extractive. The method comprises the steps that maca powder is placed into a microwave dryer, heated to 50-60 DEG C for 15-25min, and cooled to a room temperature; enzyme deactivation treatment is conducted; enzyme activity is destroyed; glucosinolate hydrolysis is prevented; backflow extraction is conducted; water is added to an extractive; the extractive is stirred, stands and is precipitated; supernatant liquid is separated and concentrated; beta-cyclodextrin is added; stirring is conducted for 50-70min; the extractive is embedded; volatilization of glucosinolate is prevented; vacuum drying is conducted; and the maca extractive is obtained. The method can effectively prevent hydrolysis of an available component, namely glucosinolate, in maca, and in particular can effectively prevent volatilization of glucosinolate as the extractive is embedded at normal temperature and pressure; the component is reserved to the greatest extent for improving an effect; a stimulation feel during oral administration is reduced; and the dosage is reduced.

Description

[0001] technical field [0002] The invention relates to a preparation method of maca extract, which belongs to the technical field of plant extraction. Background technique [0003] Maca is an annual herb of the genus Lepidium in the family Brassicaceae. It is native to the Andes in Peru at an altitude of 3,500 m. normal growth. Maca is comparable to ginseng in terms of its nutritional content and its ability to enhance energy and endurance, so it is often called "Peruvian Ginseng (Peruvian ginseng)". Maca has a long history. For thousands of years, as one of the important food sources of local indigenous people, Maca has rich nutritional value and medicinal effects, especially in enhancing energy and fertility. , is regarded as a precious gift from the gods of the Andes. The planting area of ​​maca in South America is relatively large, but because maca absorbs a lot of soil nutrients during the growth, under the original farming conditions, the land after maca root ...
