Problems solved by technology

The main function is to regulate the survival and growth environment of intestinal beneficial bacteria. There is a large demand in domestic and foreign markets, and high-grade products are all imported. The domestic variety is relatively single, and the functionality cannot meet various market demands.
The traditional production process can only separate products with a molecular weight above 500Da, and the rest will be used as fructooligosaccharide (food) syrup

Embodiment 1

[0078] Wash the chicory (Jerusalem artichoke) and shred it, then heat the water for leaching according to the solid-to-liquid ratio of 1:1.5, the leaching temperature is controlled at 60°C, and the leaching time is 45min; % of diatomite filter aid, using a ceramic microfiltration membrane with an average pore size of 200nm to filter and remove impurities. The membrane surface flow rate during the filtration process is 3m / s. , the amount of activated carbon is 1wt% of the weight of the feed liquid, and the decolorization temperature is 75°C. After filtering the activated carbon, the feed liquid is cooled to room temperature and sent to weakly basic anion exchange resin D301 to extract inulin, and then use deionized water For elution, the eluate is first filtered and concentrated with an ultrafiltration membrane with a molecular weight cut-off of 2500, and the concentrated solution is spray-dried to obtain the first-grade inulin. Drying to obtain the second-stage inulin, the per...

Embodiment 2

[0080] Wash the chicory and cut it into shreds, add water for extraction according to the solid-to-liquid ratio of 1:2, control the extraction temperature at 55°C, and extract for 40 minutes; after the initial removal of solid residues in the extraction solution, add about 2wt% of silicon The algal earth filter aid uses a ceramic microfiltration membrane with an average pore size of 50nm to filter and remove impurities. The membrane surface flow rate during the filtration process is 2m / s. After the filtrate is collected, it is added to the decolorization kettle for decolorization treatment. The weight of the feed liquid is 3wt%, the decolorization temperature is 80°C, and after the activated carbon is filtered out, the feed liquid is cooled to room temperature and sent to the strong acidic cation exchange resin D001-F to extract inulin, and then eluted with deionized water. The eluate is firstly filtered and concentrated with an ultrafiltration membrane with a molecular weight ...

Embodiment 3

[0082] Wash the chicory and shred it, add water according to the solid-to-liquid ratio of 1:1.2 for leaching, control the leaching temperature at 50°C, and leaching time for 60 minutes; after the leaching solution initially removes solid residues, add about 2wt% silicon Algae earth filter aid, using a ceramic microfiltration membrane with an average pore size of 200nm to filter and remove impurities. The membrane surface flow rate during the filtration process is 4m / s. After the filtrate is collected, it is added to the decolorization kettle for decolorization treatment. The weight of the feed liquid is 2wt%, the decolorization temperature is 75°C, and after the activated carbon is filtered out, the feed liquid is cooled to room temperature and sent to the strong basic anion exchange resin D201 to extract the inulin, and then eluted with deionized water. The solution is firstly filtered and concentrated with an ultrafiltration membrane with a molecular weight cut-off of 2500, a...

Abstract

The invention relates to a molecular-level production process and device of inulin, and belongs to the technical field of natural plant extraction. The invention provides a molecular-grade inulin production technology, which utilizes a molecular weight grading and separating device, i.e., inulin is divided into four different grades of products with the molecular weight of more than 2500, more than 1000, more than 500 and less than 500 and more than 200 according to the molecular weight.

Description

technical field [0001] The invention relates to a molecular-level production process and device of inulin, belonging to the technical field of natural product extraction. Background technique [0002] Inulin (inulin) is a functional health food edible fiber extracted from the rhizome of chicory (or Jerusalem artichoke) plant by hot soaking. It is widely used in special food, formula milk powder for the elderly, and nutritional health food. The main function is to regulate the survival and growth environment of intestinal beneficial bacteria. There is a large demand in domestic and foreign markets, and high-grade products are all imported. The domestic variety is relatively single, and the functionality cannot meet various market demands. The traditional production process can only separate products with a molecular weight above 500Da, and the rest will be used as fructooligosaccharide (food) syrup. Contents of the invention [0003] The invention provides a production...
