Problems solved by technology

[0004] Due to some functional ingredients in maca, such as polysaccharides, glucosinolates, alkaloids, etc., the structure will be destroyed under the action of high temperature for a long time, and the efficacy will be lost. The extraction time at normal temperature is very long, the extraction rate is low, and resources are wasted; The functional properties of coffee include both water-soluble and fat-soluble components. A single solvent can not completely extract the functional components, which also causes a waste of resources.

Abstract

The invention provides a preparation method for high-activity lepidium meyenii extract. The preparation method is characterized by comprising the following steps of: crushing fresh or dry lepidium meyenii roots, and performing primary ultrasonic reinforced extraction, primary solid-liquid separation and primary low-temperature supernatant concentration under the conditions of certain liquid/solid ratio and 20 to 50 DEG C by taking water as a solvent; performing secondary ultrasonic reinforced extraction, secondary solid-liquid separation and secondary low-temperature supernatant concentration on filter residues under the conditions of certain liquid/solid ratio and 20 to 50 DEG C by using an ethanol-water solution; and mixing the two concentrated solutions, and drying the mixture at low temperature or quickly to obtain powdery lepidium meyenii extract. The preparation method has the characteristics of high speed, high efficiency, completeness of functional component extraction, capability of preventing the damage of heat-sensitive functional components of lepidium meyenii, high bioactivity of the extract, low energy consumption, low cost and the like. The lepidium meyenii extract prepared by the preparation method provided by the invention has the effects of eliminating fatigue, resisting pressure, improving immunity, alleviating climacteric syndromes, resisting prostatic hyperplasia, enhancing sexual function, and the like.

Description

technical field [0001] The invention belongs to the technical field of extracting plant functional components, and in particular relates to a preparation method of a highly active maca extract. Background technique [0002] Maca (Lepidium meyenii), also known as Maca, Peruvian ginseng, etc., is an annual herb belonging to the genus Brassicaceae, with a plant height of about 15-20cm, with enlarged roots and short stems and leaves that grow close to the ground. Arranged in a rose shape, self-pollinated, the fruit is a short silique, and the seeds are oval. The swollen root is the main edible part, 2-8 cm in diameter. According to its different colors, maca is divided into 13 types such as white, yellow, purple, red, gray or white with red, white with purple, and the average root weight and biological characteristics of each type are different. Maca is rich in nutrients and has important physiological functions including: eliminating fatigue, anti-stress, improving immunity, ...
