Preparation method of active pseudo-ginseng ultramicro powder

Abstract

The invention discloses a preparation method of an active pseudo-ginseng ultramicro powder, wherein the preparation method comprises the following steps: (1) cleaning fresh pseudo-ginseng root main roots, and cutting into pseudo-ginseng slices; (2) cooling the pseudo-ginseng slices to freeze the pseudo-ginseng slices; (3) at the pressure intensity of 10-20 Pa, holding for 1-2 hours, making the temperature rise to 0 DEG C from -30 DEG C to -40 DEG C in 20-30 hours, and then making the temperature rise to 20 DEG C from 0 DEG C in 2-4 hours; and obtaining freeze-dried pseudo-ginseng slices; and (4) smashing the freeze-dried pseudo-ginseng slices for 2-10 min at a low temperature with a jet mill, to obtain the active pseudo-ginseng ultramicro powder having more than 95% of the micro powder with the particle size of 20 [mu]m or less. Medicinal active ingredients are avoided from generating oxidation, decomposition and other phenomena due to heating, drying and smashing under ordinary pressure, and the mouthfeel, color, luster and quality are basically the same as those of fresh products; and the product has extremely good water rehydration, can quickly absorb water to recover, can maximize retention of unique nutritional ingredients and active ingredients of pseudo-ginseng, and gives full play to pseudo-ginseng pharmacological functions.

Description

technical field

[0001] The present invention relates to a preparation method of notoginseng superfine powder, in particular to a preparation method of active notoginseng superfine powder. Background technique

[0002] Panax notoginseng has a planting history of more than 400 years. It is a pearl in the treasure house of medicine in the motherland and a treasure recognized both at home and abroad. Panax notoginseng contains dozens of saponins, more than ten kinds of amino acids, more than ten kinds of trace elements, dozens of kinds of volatile oils, notoginseng polysaccharides, notoginseng flavonoids, and various physiologically active substances such as Vb and ve necessary for human body. The main active ingredients are easy to decompose at high temperature, resulting in the loss of biologically active substances in Sanqi and reducing the efficacy of Sanqi. Modern medical and pharmacological studies have found that Panax notoginseng has obvious functions of dilating blood ...
