Problems solved by technology

[0005] But research finds, there is following problem in existing polysaccharide extraction process in Moringa: 1, Moringa lacks the irrigation of selenium-enriched nutrient solution in the planting link, makes blade thickness, photosynthesis weaken, and the selenium-enriched contained in leaf petiole There are not many polysaccharides; 2. After the conventional raw materials are dried and crushed at high temperature, a large amount of polysaccharides have been lost with the evaporation of water, and then the purity and yield of polysaccharides are greatly reduced after water extraction with low solubility; 3. The extracted waste residue and waste liquid contain a large amount of flavonoids, moringa oil, moringa and other nutrients. If it is directly dumped, it will cause a waste of resources. If it can be further extracted and utilized, it will greatly improve the quality of moringa. economic benefits

Abstract

The invention discloses an extraction method of selenium-rich moringa oleifera, and relates to the technical field of moringa oleifera deep processing. On the basis that selenium-rich polysaccharide has good solubility in boiling water, the extraction method starts from a culture method of the selenium-rich moringa oleifera, purity and yield of polysaccharide extraction and re-extraction of nutritional ingredients in waste residues, and includes the procedures of selection and preprocessing of raw materials obtained through screening experiments, freezing and crushing, pressurizing and extraction, re-extraction of filter residues, alcohol precipitation and freeze-drying. The method is scientific and reasonable, the extraction rate and purity of the selenium-enriched polysaccharide are greatly improved, the total content of selenium is greatly improved, a large amount of pterigospermin is extracted from the waste residues, and the economic benefits of the moringa oleifera are remarkablyimproved.

Description

technical field [0001] The invention relates to the technical field of deep processing of Moringa oleifera, in particular to a method for extracting selenium-enriched Moringa oleifera. Background technique [0002] Moringa is a perennial plant of Moringaceae Moringa, a fast-growing tree species native to the southern foot of the Himalayas in northern India. It has strong drought tolerance and likes to be born in sandy loam. The roots, stems, leaves, flowers, seeds, branches and bark of Moringa oleifera are rich in nutrients and medicinal ingredients. Moringa is rich in moringa flavonoids, polysaccharides, proteins, amino acids and vitamins, among which amino acids include essential amino acids that the human body cannot synthesize by itself or whose synthesis rate cannot meet its own needs. [0003] It has been confirmed by research that the protein content in leaves and kernels of Moringa oleifera is 4 times that of milk, the total flavonoid content of Moringa oleifera rea...
