Problems solved by technology

The adsorption resin has a better adsorption effect on the fat-soluble components and color in yacon, but it is difficult to remove the water-soluble co-existing components in yacon oligosaccharides
Using column chromatography and the combination of the above methods, although relatively high-purity yacon oligosaccharides can be obtained, on the one hand, the process is relatively complicated, and on the other hand, the cost is too high, which is not conducive to the application and development of yacon oligosaccharides.
Although enzymatic fermentation can increase the yield and content of yacon oligosaccharides, and degrade part of the water-insoluble fiber, polysaccharides and pectin of yacon into fructo-oligosaccharides, the conditions are harsh, and at the same time, some fructo-oligosaccharides can be degraded into Degraded into monosaccharides, there are also the above purification problems

Abstract

The invention relates to a production method of smallanthus sonchifolius oligosaccharide. The production method comprises the steps of: washing, sorting, peeling and rapidly chopping a fresh smallanthus sonchifolius raw material, and pulping the chopped material in hot water to realize enzyme inactivation so as to reduce the degradation and decomposition opportunities and the loss of the smallanthus sonchifolius oligosaccharide; filtering to remove insoluble filter residues and fibers to obtain a crude extract of the smallanthus sonchifolius oligosaccharide, and adding a clarifying agent into the crude extract to precipitate and to remove macromolecular components, such as protein, water-soluble enzyme, tannins, pectin and pigment, and part of metal salt ions from the solution; filtering and separating the solution, then precipitating the separated solution by an organic solvent to further remove components, such as protein, tannins, pectin, amino acids, peptides and polysaccharides, and part of metal salt ions in the solution, and recovering the solvent to obtain the high-content smallanthus sonchifolius oligosaccharide.

Description

Technical field: [0001] The invention belongs to the technical field of extracting and removing impurities from biological products, and in particular relates to a process for extracting active fructo-oligosaccharides in yacon. Background technique: [0002] Yacon (Smallanthus sonchifolius), also known as snow lotus potato, chrysanthemum yam, Yalong fruit or Yacon, is an English name (yacon). It belongs to the genus Sunflower of the Compositae family. Traditional rhizome food was introduced to Japan, Brazil, South Korea and some European countries in the 1980s, and is currently successfully planted in Yunnan, Sichuan, Guizhou, Fujian, Hainan, Hunan, Hubei, Shandong, Henan, Hebei and other places in China. [0003] The fruit (tuber) of yacon is similar to sweet potatoes, but it is very different from sweet potatoes. Yacon is rich in more than 20 kinds of essential amino acids and rich minerals. The pulp is juicy, light yellow, crystal clear, sweet and crisp. It tastes like a...
