Embodiment 1

[0024] Take 200L of seawater sample, filter and purify through charcoal filter layer, sand filter layer and activated carbon filter layer in turn, then conduct electrodialysis on the filtrate, adjust the flow rate to 3cm / s, and the current density to 3A / dm 2 , The temperature is 60°C, and the multi-stage ion exchange membrane electrodialysis method is used to treat the salinity below 3. The obtained desalted solution was pre-concentrated by the open heating method until the temperature of the solution reached 105°C, then rotary evaporated at 40°C under a pressure of 10kPa until it was light yellow and viscous, and the obtained viscous solution was diluted to 500mL with distilled water, and 2L of 95% Stir with ethanol, crystallize and extract at low temperature at 0-5°C for 10 hours, filter the mixture at 20kPa and wash the crystals with a small amount of ethanol, distill the filtrate to recover the ethanol solvent, repeat the steps of 95% ethanol crystallization, filtration, an...

Embodiment 2

[0026] Take 400L of seawater sample, filter and purify through charcoal filter layer, sand filter layer and activated carbon filter layer in turn, then conduct electrodialysis on the filtrate, adjust the flow rate to 3cm / s, and the current density to 2A / dm 2 , temperature 80°C, treated with multi-stage ion exchange membrane electrodialysis until the salinity is lower than 3. The obtained desalted solution was pre-concentrated by the open heating method until the temperature of the solution reached 105°C, then rotary evaporated at 100°C under a pressure of 50kPa until it was light yellow and viscous, diluted to 1000mL with distilled water, and added 2L of 95% Stir with ethanol, crystallize and extract at a low temperature of 0-5°C for 10 hours, filter the mixture at 50kPa and wash the crystals with a small amount of ethanol, distill the filtrate to recover the ethanol solvent, repeat the steps of 95% ethanol crystallization, filtration, and washing twice for the remaining filtra...

Embodiment 3

[0028] Take 400L seawater sample, centrifuge at 1500r / min for 20min, and electrodialyze the supernatant, adjust the flow rate to 3cm / s, and the current density to 5A / dm 2 , The temperature is 60°C, and the multi-stage ion exchange membrane electrodialysis method is used to treat the salinity below 3. The obtained desalted solution was firstly evaporated in an open-type atmosphere, heated to 100°C, and kept until the temperature reached 105°C; then rotary evaporated at 40°C under a pressure of 10kPa until it became viscous, and the resulting viscous liquid was diluted to 800mL with distilled water. Add 2.5L of 95% ethanol and stir, crystallize and extract at a low temperature of 0-5°C for 12 hours, centrifuge the mixture at a speed of 1000r / min for 30 minutes, pour out the supernatant, recover ethanol by distillation, and vacuum-dry the obtained crystals to obtain the yellowish crystal of the present invention. The active sugar complex contains 30% of carbohydrates (calculated ...

Abstract

The invention relates to an active sugar composition extracted from sea and bittern, its preparation process and its composition, wherein the compound contains carbohydrates 15-35% (including deacidized sugar 5-11%), inorganic salts, vitamins and water. The invention also relates to a composition using the compound as functional component.

Description

technical field [0001] The invention relates to an active sugar complex, in particular to an active sugar complex extracted from seawater and bittern and a preparation method thereof, and also to a composition using the sugar complex as a functional component. Background technique [0002] As one of the largest resource pools on the earth, seawater not only contains a large amount of inorganic material resources, but also stores a variety of organic material resources. With the increasing scarcity of land resources in recent years, human beings pay more and more attention to the development of marine resources. Extract such as NaCl, KCl, MgCl from seawater or bittern 2 , MgSO 4 The technology of such inorganic salts has been industrialized and produced huge economic benefits. Sugars, especially polysaccharides, are one of the most important organic material resources in seawater. Because seawater bittern is highly concentrated in the process of extracting sodium chloride,...
