Embodiment 1

[0023] (1) Wash 1kg of fresh Maca root with clean water to remove impurities such as soil, then dry it, then add 1000mL of a mixture of food grade ethanol preheated to 70°C and water at a volume ratio of 8:2 according to the solid-to-liquid ratio of 1:1 , then crush the mixture and let it stand for 24 hours;

[0024] (2) Add a mixture of edible grade ethanol and water in a volume ratio of 8:2 to the mixed material obtained in step (1) until the mixed material is completely submerged, and then percolate, and supplement the solvent at the same time. When the outflowing percolate reaches the mixed material When the volume is 8 times of the volume, stop the rehydration and retain the solid material;

[0025] (3) Concentrate the percolation solution obtained in step (2) in a water bath at 50°C under reduced pressure to 1 / 4 of the volume, and then perform centrifugal filtration to obtain 2000 mL of concentrated solution I;

[0026] (4) Add a mixture of edible grade ethanol and wate...

Embodiment 2

[0029] (1) Wash 1kg of fresh Maca root and dry it, then add food-grade ethanol preheated to 70°C and water at a ratio of 7:3 according to the solid-to-liquid ratio of 1:1, then crush the mixture and let it stand 24 hours;

[0030] (2) Add edible grade ethanol and water to the mixed material obtained in step (1) according to the mixture of 7:3 until the mixed material is completely submerged, and then percolate, and supplement the solvent at the same time. When the volume doubles, stop rehydration and retain the solid material;

[0031] (3) Concentrate the percolation solution obtained in step (2) in a water bath at 50°C under reduced pressure to 1 / 3 of the volume, and then perform centrifugal filtration to obtain 1000 mL of concentrated solution I;

[0032] (4) Add food-grade ethanol and water to the solid material obtained in step (2) at a ratio of 0.1:9.9 until the solid material is completely submerged, and then carry out secondary percolation, and at the same time repleni...

Embodiment 3

[0035] (1) Wash 1kg of Maca dry root and dry it, then add food-grade isopropanol and water, which are preheated to 80°C, into an equal volume mixture according to the solid-to-liquid ratio of 1:1, then crush the mixed material, and let it stand set for 24 hours;

[0036] (2) Add food-grade isopropanol and water to the mixed material obtained in step (1) in an equal volume until the mixed material is completely submerged, then percolate, and supplement the solvent at the same time. When the volume reaches 10 times, stop rehydration and keep the solid material;

[0037] (3) Concentrate the percolation solution obtained in step (2) in a water bath at 50°C under reduced pressure to 1 / 3 of the volume, and then perform centrifugal filtration to obtain 2500 mL of concentrated solution I;

[0038] (4) Add a mixture of edible grade isopropanol and water in any proportion to the solid material obtained in step (2) until the solid material is completely submerged, and then carry out sec...

Abstract

The invention provides a preparation method of Maca active extracts. According to the method, firstly, fresh Maca roots or dry Maca roots are pre-treated, then, percolation is carried out for twice after the treatment by a pre-heated mixed solvent, freeze drying is carried out after additives are added into concentrated liquid, and the Maca active extracts are obtained. The method provided by the invention is simple, the operation is easy, the nutrition ingredients and active substances of the Maca are sufficiently and fully integrated, the active ingredient enzymolysis is prevented, and in addition, the loss and the damage of nutrition ingredients and active ingredients can be effectively prevented. The obtained product can realize the instant eating effect, can also be used as raw materials to be made into health care foods in tablets, capsules and the like, or can be added into various kinds of food as additives to realize the application.

Description

technical field [0001] The invention relates to a preparation method of nutritional health food, in particular to a preparation method of Maca active extract, which belongs to the technical field of biological extract preparation. Background technique [0002] Maca is a cruciferous plant native to the high-altitude areas of the Andes Mountains in South America. As early as 3800 BC in the pre-Inca period, the ancient Indian indigenous people had grown Maca as a staple food. In 1843, Maca was discovered and recorded by Western scholars for the first time. In 1961, after the biologist Chacon published his work on Maca, it attracted the attention of various countries. At present, Maca, as a nutritional supplement, has been promoted to all parts of the world, and its research and development and production are in the ascendant. [0003] The bulbous root of Maca is rich in sugar, starch, protein and fiber, and also rich in lipids. Its amino acid composition is rich in essential a...
