Example Embodiment

[0018] Example 1:

[0019] Take 500 Kg of fresh Jerusalem artichoke tubers, wash them with clean water, shred them, and use purified water for countercurrent extraction. The ratio of material to liquid is 1:1.5, the extraction temperature is 60°C, and the extraction time is 40 min. The crude extract is obtained. The powder concentration is 4.4%. Then the crude extract is ultrafiltered with an ultrafiltration membrane (molecular weight of 10,000 Daltons), and then desalted and decolorized by a strong acid cation exchange resin and a weakly basic anion exchange resin to obtain a colorless, clear and transparent effluent. Filter (molecular weight 500 Daltons) concentrated to inulin concentration of 25%, and then spray-dried to obtain 51 Kg of inulin powder with a purity of 93.4% and an ash content of 0.15%.

[0021] Example 2:

[0022] Take 500 Kg of fresh Jerusalem artichoke tubers, wash them with water, shred them, and put them in pure water for 40 min. The material-to-liquid ratio is 1:1.5, and the extraction temperature is 60℃ to obtain a crude extract. The crude extract contains inulin The concentration is 4.2%. Then, the crude extract was purified by the lime milk-phosphoric acid method to remove impurities and clarify the crude inulin extract, and then desalted and decolorized by strong acid cation exchange resin and strong basic anion exchange resin to obtain a colorless, clear and transparent effluent. After concentration and spray drying, 51.8 Kg of inulin powder was obtained, with a purity of 87.2% and an ash content of 0.16%.

[0024] Example 3:

[0025] Take 300 Kg of fresh Jerusalem artichoke tubers, wash them with clean water, shred them, and use purified water for countercurrent extraction. The ratio of material to liquid is 1:3, the extraction temperature is 40°C, and the extraction time is 50 min to obtain a crude extract. The powder concentration is 2.7%. Then the crude extract is ultrafiltered with an ultrafiltration membrane (molecular weight of 10,000 Daltons), and then desalted and decolorized by strong acid cation exchange resin and weakly basic anion exchange resin to obtain a colorless, clear and transparent effluent. Filtration (molecular weight 700 Daltons) was concentrated to an inulin concentration of 20%, and then spray-dried to obtain 33 Kg of inulin powder with a purity of 90.7% and an ash content of 0.19%.

Abstract

The invention discloses a refining method of inulin from jerusalem artichoke as a raw material. The refining method comprises the following steps: (1) cleaning the fresh raw material, shredding and carrying out countercurrent extraction; (2) filtering with an ultra-filtration membrane to obtain an inulin ultrafiltrate; (3) decolorizing the inulin ultrafiltrate by virtue of ion exchange resin and desalting; and (4) carrying out nanofiltration concentration and spray drying to obtain the inulin product. Since the countercurrent extraction is adopted in the refining method disclosed by the invention, the leaching of active components can be accelerated and the yield of the active components is greatly improved; due to the strongly acidic cation and weakly basic anion double-resin column, the material loss caused by a plurality of resin columns is reduced and the yield of the inulin can be also improved; the nanofiltration is performed by the nanofiltration membrane, a majority of glucose, fructose and sucrose can be removed and thus the purity of the inulin is improved and the quality of the inulin is also improved.

Description

Technical field [0001] The invention involves the field of food processing technology in new resources, especially a refined method of chrysanthemum powder with chrysanthemum or chrysanthemums. Background technique [0002] Chrysanthemum powder, also known as chrysanthemum, is a linear straight polysaccharide connected by β- (2 → 1) glucoside bond. The end often has a glucose residue with a polymer of 2-60.Chrysanthemum powder is another form of energy storage in addition to starch plants. It exists widely in almost all plants, of which the content of chrysanthemum and chrysanthemum is the highest.As a natural water -soluble dietary fiber, chrysanthemum powder is almost not digested and absorbed by the stomach and small intestine after entering the human body.Absorbing, controlling blood sugar and reducing blood lipids.As a natural functional food ingredient, chrysanthemum powder can be used as fat substitutes, and it can also improve the quality and nutritional characteristics o...
