Problems solved by technology

However, this method has a problem that since the fresh herb is cut, immersed in a salt solution, and stirred for a long time at a high temperature higher than room temperature, most of the organic compounds contained in Echinacea except water-insoluble dietary fiber lost, and the saline solution does not ensure strong desalination
However, since electrodialysis desalting requires continuous circulation of the liquid phase sample, it is not possible to completely remove the salt from the liquid
Also, the method is not applicable to samples other than liquids
[0017] (3) Same as electrodialysis, ultrafiltration cannot selectively eliminate only sodium salts, and it is also disadvantageous in removing sodium and useful minerals such as potassium, calcium and magnesium
Ultrafiltration methods have other drawbacks: low molecular weight organic compounds of less than 200 Daltons are lost in the sample, and maintenance and management of equipment is expensive
It was found that the thick shore grass samples studied above had anti-obesity effects, but still retained the sodium chloride contained in the raw material, thus limiting their direct development into functional materials

Embodiment 1

[0091] Example 1: Evaluation of the desalination effect of cold water extraction of Salicornia

[0092] To 100 g of dry powder of Salicornia europaea were added 2 liters of cold water (4°C and 9°C), room temperature water (20°C) and hot water (100°C), respectively. Extraction was performed with stirring (300 rpm) at low temperature (4°C and 9°C) and room temperature (20°C). Hot water extraction was performed using a 100 °C reflux condenser.

[0093] To determine the optimal conditions for maximizing desalination, the stirred mixture was centrifuged at 10,000 rpm for 20 minutes at 5 minute intervals. The supernatant was vacuum filtered through a membrane filter (0.45 μm pore size), and then analyzed for salinity (ATAGOES-421, ATAGO Co.LTD. Japan) and Brix (Brix) (ATAGO PAL-1, ATAGO Co.LTD. Japan ). In addition, the supernatant was concentrated in vacuo, freeze-dried (EYELA FDU-2200, ETELA, Japan), and then analyzed for total solid content. The measured total solids content,...

Embodiment 2

[0102] Embodiment 2: Prepare desalination nutritional composition from Salicornia chinensis, Suaeda asparagus and Aesptaceae

[0103] The desalination nutritional composition was prepared using three kinds of plants (Salspore, Suaeda asparagus, and Aesophanat), which are known to be extreme halophytes naturally growing in Korea. Fresh plants were washed with tap water and freeze-dried for pulverization. Based on the results of Example 1, where extraction of organic matter was minimized when extraction was performed with cold water at 4°C or lower for 4 minutes or less while effectively removing salt, 100 g of dry powder was added in 2 L of cold water (4°C) , stirred at 4°C for 4 minutes, and centrifuged at 10,000 rpm for 20 minutes. Then, the supernatant with high salt content is removed, and the desalted precipitate is recovered. The recovered precipitate was again desalted by the same method as above to minimize the remaining sodium salt. The precipitate thus obtained was...

Embodiment 3

[0123] Example 3: Preparation of functionally enhanced desalinated extracts from halophytes (hot water and ethanol extracts)

[0124] Add 100 g of function-enhanced desalted nutritional compositions (desalted powders) from Salicornia, Suaeda asparagus, and Aesophagus prepared in Example 2 to each of 2 L of distilled water, and reflux extraction at 100° C. for 2 or 4 hours , centrifuged, filtered, concentrated under pressure, and freeze-dried to obtain a functionally enhanced desalinated hot water extract derived from halophytes.

[0125] Add 100 g of function-enhanced desalted nutritional compositions (desalted powders) from Salicornia chinensis, Suaeda asparagus, and Aesophages prepared in Example 2 to each of 2L of 95% ethanol, and reflux at 75±1°C extract. 2 or 4 hours, cool to room temperature, and centrifuge. The supernatant was filtered and concentrated under pressure and freeze-dried, resulting in a functionally enhanced desalted ethanol extract derived from halophyte...

Abstract

Disclosed are a functionally reinforced desalted nutritional composition, a desalted extract and a cold-water-extracted salt substitute, which are derived from halophytes that grow in coastal regionsunder highly saline conditions and thus retain high salt concentrations, as well as the use of the desalted nutritional composition for combatting obesity. More particularly, this invention relates toa functionally reinforced desalted nutritional composition, a desalted extract and a salt substitute cold-water-extracted from halophytes that inhabit extreme environments of high salinity under highsalt stress, the halophytes being desalted through a cold water extraction process at a low temperature based on the difference in water solubility of salts with change in temperature to allow only sodium chloride to be selectively removed, and the composition thus having decreased sodium content as well as having increased content of useful minerals such as potassium, as well as nutrients and physiologically active substances, which are naturally contained in halophytes.

Description

technical field [0001] The present invention relates to functionally enhanced desalted nutritional compositions, desalted extracts and cold water extracted salt substitutes derived from halophytes that grow in coastal areas under high salinity conditions and thus maintain high salt concentrations, and also relate to Use of a desalted nutritional composition for combating obesity. More specifically, the present invention relates to functionally enhanced desalted nutritional compositions, desalted extracts and salt substitutes derived from cold water extracts of halophytes grown in extreme environments of high salinity under high salt stress , based on the fact that the water solubility of salt varies with temperature, the halophytes are desalinated by a cold water extraction process at low temperature so that only sodium chloride is selectively removed, and thus the composition has a reduced sodium content and Has increased content of useful minerals such as potassium as well ...
