Problems solved by technology

[0004] At present, the process of maca products is generally as follows: 2) Maca extraction and percolation extraction, this method takes a long time and low efficiency; 2) Heating and reflux extraction with water and ethanol, the disadvantage of this method is the activity The ingredients are easy to lose and the extraction is incomplete; 3) Organic solvents are used for extraction, and then concentrated extraction, but the organic solvents are easy to remain and cause pollution; 4) Supercritical carbon dioxide is used to extract the active ingredients of maca, and the equipment cost is high; 5) Maca is naturally air-dried , easy to mold; 6) Drying maca with hot air can easily destroy the active ingredients in maca; while vacuum freeze-drying maca raw materials takes a long time

Embodiment 1

[0016] A kind of preparation method of maca superfine powder, concrete preparation steps are as follows:

[0017] 1) Select 50kg of maca lumpy rhizomes without insect spots, mildew, or scars on the surface, wash the surface soil, remove surface dirt, dry the surface water, put it into a potato slicer, and cut into 10mm×10mm×10mm Macadine;

[0018] 2) Put it into a freezer and freeze it for 15 hours at a temperature of -30°C;

[0019] 3) Then, under the condition of -15°C, put it into a pulverizer for coarse crushing, coarsely crush it into frozen maca coarse powder, and then put it into a superfine pulverizer to pulverize it into a superfine powder of over 500 mesh;

[0020] 4) Immediately put the frozen maca superfine powder into the vacuum drying device, control the vacuum degree to 5 Pa, and carry out vacuum drying for 3 hours, and the drying temperature is always controlled at 25°C to obtain dried maca superfine powder.

Embodiment 2

[0022] 1) Select 50kg of maca lumpy rhizomes without insect spots, mildew, or scars on the surface, wash the surface soil, remove surface dirt, dry the surface water, put it into a potato slicer, and cut into 10mm×10mm×10mm Macadine;

[0023] 2) Put it into the freezer and freeze it at -25°C for 16 hours;

[0024] 3) Then, under the condition of -18°C, put it into a pulverizer for coarse crushing, coarsely crush it into frozen maca coarse powder, and then put it into a superfine pulverizer to pulverize it into a superfine powder over 700 mesh;

[0025] 4) Immediately put the frozen maca superfine powder into the vacuum drying device, control the vacuum degree to 10Pa, and carry out vacuum drying for 5 hours, and the drying temperature is always controlled at 20°C to obtain dried maca superfine powder.

Embodiment 3

[0027] 1) Select 50kg of maca lumpy rhizomes without insect spots, mildew, or scars on the surface, wash the surface soil, remove surface dirt, dry the surface water, put it into a potato slicer, and cut into 10mm×10mm×10mm Macadine;

[0028] 2) Put it into the freezer and freeze it for 20 hours at a temperature of -20°C;

[0029] 3) Then, under the condition of -20°C, put it into a pulverizer for coarse crushing, coarsely crush it into frozen maca coarse powder, and then put it into a superfine pulverizer to pulverize it into a superfine powder of over 800 mesh;

[0030] 4) Immediately put the frozen maca superfine powder into the vacuum drying device, control the vacuum degree to 3 Pa, and carry out vacuum drying for 5 hours, and the drying temperature is always controlled at 29°C to obtain dried maca superfine powder.

Abstract

The invention belongs to the technical field of natural plant deep processing, and particularly relates to a preparation method of maca superfine powder. The preparation method particularly comprises the following steps: firstly, freezing maca, and directly crushing the frozen maca at a low temperature into ultrafine powder; and then carrying out vacuum drying instantly so as to obtain the dry maca superfine powder which keeps bioactivity fully. Not only is problem of drying difficulty of maca raw materials solved, but also the raw material freezing step of vacuum freezing and drying is reduced; and the time for preparing the maca superfine powder is shortened greatly.

Description

technical field [0001] The invention belongs to the technical field of deep processing of natural plants, and in particular relates to a preparation method of maca superfine powder. Background technique [0002] Maca (Maca), also known as Maca, is an annual or biennial herb with storage roots, short stems and leaves that grow close to the ground. It is native to the South American Andes at an altitude of 3500-4500 meters. At present, it is in Yunnan and Xinjiang in my country. It has been successfully introduced on a large scale. It is a plant of the genus Lepidium in the Cruciferae family (Cruciferae), and its scientific name is Lepidium meyenii. [0003] Maca is a medicinal and edible plant, and the underground swollen root is the main edible part. According to different colors, maca is divided into 13 types, including white, yellow, purple, red, gray, or white with red, and white with purple. , the average root weight and biological characteristics of each type are differ...
