Problems solved by technology
At present, there is also a process of directly extracting polysaccharides from wolfberry medicinal materials, and the product also uses polysaccharides as an index, but due to the complexity of the ingredients and the need to crush, the content is relatively low (generally 40-50%)
[0006] At present, the utilization method of wolfberry polysaccharide is to directly mix the wolfberry extract into other raw materials for batching. Also see the patent (02115382.5) which reports the membrane separation of wolfberry polysaccharide to obtain different components of different molecular weight ranges, and even column chromatography The separation and purification method (Patent No. 02108915.9), the former is to separate polysaccharides in different molecular weight ranges, but cannot convert all polysaccharides into polysaccharides in the target molecular weight range, and the result is a waste of raw material resources; the latter is obviously not suitable for large-scale industrial production

Embodiment Construction
[0015] specific implementation
[0016] The preparation method of the active polysaccharide of wolfberry of the present invention is characterized in that: using the medicinal residue of wolfberry after immersion in 40-60 degree alcohol or heating and extracting as raw material, water is used as solvent and then extracted with water, so as to obtain the polysaccharide extract of wolfberry;
[0017] The α-amylase with α-(1→4) glycosidic bond endolytic activity was selected to enzymolyze the crude polysaccharide of Lycium barbarum in the polysaccharide extract of Lycium barbarum, so as to obtain the enzymatic hydrolyzate of Lycium barbarum polysaccharide with low molecular weight and higher activity.
[0018] The preparation method of Lycium barbarum active polysaccharide of the present invention, its general steps are as follows:
[0019] ① Weigh 200g of dried wolfberry medicinal residue, add 1800-2200ml of water, place in a 70-90°C water bath, stir and extract for 2-4 hours, e...

The present invention relates to a preparation method of wolfberry active polysaccharide, which is characterized by taking wolfberry herb residue which is quenched by 40-60 degrees of alcohol or is heated and extracted as a raw material, extracting the raw material by using water as a solvent, thereby obtaining a wolfberry polysaccharide extract; selecting alpha-diastase which has alpha-(1->4) glycosidic bond endo activity to carry out enzymolysis for a wolfberry crude polysaccharide in the wolfberry polysaccharide extract, thereby obtaining the wolfberry active polysaccharide as the wolfberry polysaccharide hydrolysate with low molecular weight and higher activity. Not only the method facilitates scale production, but also the product has strong target in quality, so that the stability of the product quality is ensured.
Description
technical field [0001] It belongs to the field of traditional agricultural transformation and the field of bioengineering, and its main application field is health food. Background technique [0002] Plant polysaccharides have a wide range of physiological activities, such as anti-tumor, enhancing immunity, anti-aging, etc., and have been developed into anti-tumor drugs and anti-aging drugs. However, there are currently two problems in the utilization or development of plant polysaccharides: [0003] One is that in the process of extracting the chemical components of botanical medicines, most of them use alcohol as a solvent, or use water as a solvent and then alcohol precipitation to remove polysaccharides, so plant polysaccharides are often not used in the industrial production process. [0004] The second is that plant polysaccharides belong to macromolecules. The molecular weight and distribution of polysaccharides have a great influence on the biological activity of po...
