Problems solved by technology

[0005] A large number of scholars have studied the extraction process of effective components of Maca, and studied how to extract glucosinolates and the best decomposition products, but the results are often counterproductive. The content of glucosinolates and decomposition products in the extract is lower than that of Maca raw materials, resulting in The embarrassing result that the activity is not as good as the original powder

preparation example Construction

[0020] The method for preparing maca powder that fully retains biological activity of the present invention includes pretreatment, freezing, freeze-drying, and pulverizing procedures, specifically including:

[0021] A. Pre-treatment: remove impurities, wash and dry the surface moisture of fresh maca;

[0022] B. Freezing: put the pretreated maca into a freezer and freeze below -20°C;

[0023] C, freeze-drying: the maca that freezes is packed in the vacuum freeze-drying device, after pre-freezing, sublimation drying, analysis drying, obtain dry active maca;

[0024] D. Pulverization: the freeze-dried maca is pulverized to obtain the target object.

[0025] Maca described in step A is more than one of Maca root, Maca fibrous root, and Maca leaf, and described Maca root, Maca fibrous root, and Maca leaf complete pretreatment, freezing, freeze-drying together or respectively , pulverizing process, can realize the purpose of the present invention.

[0026] After the maca root i...

Embodiment 1

[0034]Take the yellow mature fresh maca tubers and fibrous roots grown without pollution in Lijiang, Yunnan, remove the stems and leaves, insect eggs, diseased tubers and fibrous roots, separate the tubers and fibrous roots, wash them with clean water, and quickly dry them on the surface at room temperature; put the tubers and fibrous roots together In the freezer, freeze at -30°C for 3 hours; cut the maca roots into 4mm thick slices after freezing, and send them to the -20°C freezer together with the maca fibrous roots to be dried; maca root slices and maca Spread the roots of coffee fibrous evenly in the freeze-drying tray, put them into the contact heat transfer type freeze-drying device, after pre-freezing at -40°C, vacuumize to 50Pa, set the co-melting point at -17°C for sublimation drying, and then use Analyze and dry the material at a central temperature of 40°C until the moisture content is 5% to obtain dry active maca; after ordinary crushing, it is made into dry maca ...

Embodiment 2

[0036] Take the yellow mature fresh maca tubers, fibrous roots and leaves grown in pollution-free Lijiang, Yunnan, remove the stems, yellow leaves, insect eggs, diseased tubers and fibrous roots, separate the tubers and fibrous roots, wash them with clean water, and quickly dry them on the surface at room temperature; the tubers, Put the fibrous roots and leaves into the freezer, freeze at -40°C, and freeze for 2 hours; cut the frozen roots into 1mm thick slices, spread the thin slices evenly in the freeze-drying tray with the frozen fibrous roots and leaves, and put them into In the radiation heating type freeze-drying device, after pre-freezing at -40°C, vacuumize to 60Pa, set the co-melting point -15°C for sublimation drying, and then analyze and dry at the center temperature of the material at 45°C until the moisture content is 3%. The dry active maca is obtained; the dry maca powder is formed after ordinary crushing and passing through a 400-mesh sieve. Get the dried maca...

Abstract

The invention discloses maca powder with bioactivity fully reserved, and a preparation method and a preparation of the maca powder. The maca powder is prepared by conducting refrigerating, freeze drying and smashing on fresh maca; moisture content of the maca powder is below 5%; and the maca powder contains glucosinolate accounting for 1.1-2.75wt% of the total weight of the maca powder. The preparation method comprises the processes of preparing materials, refrigerating, conducting freeze drying, and smashing. The preparation is characterized in that the maca powder is matched with auxiliary materials accepted in the field of pharmacy, and prepared into a tablet, power, dissolved medicine or a capsule. The preparation method adopts a vacuum freeze drying technology, and the activity of myrosinase in the maca is inhibited during the course of storage and drying; a hydrolysis reaction condition for myrosinase and glucosinolate is destroyed by crystallization of moisture in the maca; oxidation of active components of the maca is reduced due to the low-temperature drying; and characteristic substances-glucosinolate, the bioactive components such as protein, and other volatile components are reserved to the greatest extent.

Description

technical field [0001] The invention belongs to the technical field of deep processing of agricultural products, and in particular relates to a maca powder which fully retains biological activity, a preparation method and a preparation thereof. Background technique [0002] Maca (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, my country has successfully introduced it in Yunnan and Xinjiang on a large scale. For the genus Cruciferae (Cruciferae) Lepidium )plant. Maca is a medicinal and edible plant. The underground swollen root is the main edible part. The surface color is black, purple, yellow, etc. Maca is rich in protein, amino acid, sugar, minerals and multivitamins. It has been eaten in South America for more than 5,800 years. It is traditionally used for strengthening the body, improving fertility, improving sexual fu...
