Embodiment 1

[0020] The preparation process of wolfberry oligosaccharides is as follows:

[0021] 1) Material selection: choose mature, pest-free and high-sugar wolfberry as raw material;

[0022] 2) Drying: Dried wolfberries in an oven at 70°C for later use;

[0023] 3) Pulverization: crush the dried wolfberry fruit and pass through a 60-mesh sieve to obtain wolfberry fruit powder;

[0024] 4) Degreasing: Add 3L of petroleum ether (boiling point: 60-90°C) to 1K wolfberry powder, and reflux for 3 hours;

[0025] 5) Extraction: Ethanol reflux extraction is used, the ratio of solid to liquid is 1:5, the alcohol concentration is 70%, the extraction temperature is 60°C, the extraction time is 2 hours, and the extraction is performed twice;

[0026] 6) Decolorization: The extract is concentrated under reduced pressure to about 1 / 10 of the original volume, and the concentrated solution is decolorized with polyamide;

[0027] 7) Membrane separation: adjust the c...

Abstract

The invention relates to a preparation method of lycium barbarum oligosaccharide. The preparation method comprises the following steps: selecting materials; drying; crushing; degreasing; extracting; decolorizing; separating by a membrane; drying. According to the preparation method, the ethanol reflux extract process is carried out to prepare lycium barbarum oligosaccharide, and the obtained oligosaccharide is decolorized by macroreticular resin, thus the pigment can be effectively removed, and the purity of oligosaccharide can be improved. The prepared oligosaccharide has the physicochemical characteristics of low heat, stability, safety and non-toxicity and the like, also has the physiological functions of enhancing intestinal probiotics and preventing decayed tooth and the like, and can be widely applied to the field of health foods and medicines.

Description

technical field [0001] The invention belongs to the field of extracting functional components of plants, and in particular relates to a method for extracting oligosaccharides from wolfberry. Background technique [0002] Lycium barbarum is the ripe and dry fruit of Lycium barbarum, a plant of the Solanaceae family. It is a traditional and precious Chinese medicinal material, which has the effects of nourishing the kidney and liver, moistening the lungs and improving eyesight. Pharmacological studies have shown that wolfberry has the pharmacological effects of enhancing immunity, anti-tumor, anti-aging, increasing hematopoietic function, and anti-fatty liver. The study of the chemical constituents in Lycium barbarum is conducive to revealing its pharmacological effects in depth, and it is of great significance to develop this precious resource reasonably and effectively. [0003] Oligosaccharides, also known as oligosaccharides, not only have good physical and chemical pro...
