We investigated the physicochemical properties and physiological activities of glasswort juice fermented naturally for different periods of time. Glasswort juice fermented for six years (LFGJ) showed higher crude fiber and lower NaCl content than glasswort juice fermented for two years (SFGJ). Fermented glasswort juice contained K, Mg, and Ca as the main minerals, and the mineral content in both SFGJ and LFGJ were similar. The main free amino acids of fermented glasswort juice were determined to be alanine, proline, aspartic acid, and lysine. The leucine and aspartic acid content in LFGJ was higher than that in SFGJ. SFGJ had higher 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid) (ABTS$^+$) radical-scavenging activities than LFGJ. Fermented glasswort juice showed high ACE inhibition and ${\alpha}$-glucosidase inhibition activities regardless of how long it was fermented. An oral glucose tolerance test was carried out in rats fed diets containing 4% NaCl (control) or 4% NaCl+2% LFGJ (LFGJ). The LFGJ group showed enhanced glucose tolerance compared to the control group.

This study was carried out to investigate the effects of Salicornia herbacea L. powder (SHP) on white bread quality. Crude fiber, crude ash, Fe and Ca contents of bread with SHP were higher than those of control and increased with increasing SHP concentration. The pH of bread with SHP was higher than that of without SHP. Salinity of bread prepared with SHP (0.6, 1.2, 1.8, and 2.4%) did not show any significant difference compared with control. L and b value of the bread were decreased by the addition of SHP. The inside color of SHP (1.8%) added bread did not show significant difference compared with control. The texture (hardness, chewiness, cohesivness, and springiness) of bread prepared with SHP was higher than that of without SHP. DPPH-radical scavenging activity of SHP added bread (0, 0.6, 1.2, 1.8, 2.4, and 6.0%) was 27.95, 30.42, 33.91, 39.51, 41.17 and 63.82%, respectively. DPPH-radical scavenging activity was increased significantly by the addition of SHP. Inhibition of lipid rancidity and total polyphenol contents of the breads were increased by the addition of SHP.

This study evaluated the quality characteristics of mungbean starch gel prepared with different amounts of Salicornia herbacea L. powder. In order to determine the optimal addition level of Salicornia herbacea L. powder, samples of mungbean starch with 0, 2, 4, 6 and 8% of Salicornia herbacea L. powder substitute were prepared, after which physicochemical, textural and sensory quality characteristics were measured. Upon increasing Salicornia herbacea L. powder levels in the formulation, moisture contents of samples decreased, except the 6% addition sample, and salinity levels increased. Total phenolic contents and DPPH radical scavenging activities also increased significantly upon addtion of Salicornia herbacea L. powder. According to the texture analysis, hardness and gumminess decreased with increasing amounts of added Salicornia herbacea L. powder. From the sensory tests, 4% Salicornia herbacea L. powder sample received the highest overall acceptability score with proper levels of flavor, saltiness and texture. As a result, to increase usage of Salicornia herbacea L., the optimal formulation consisted of 4% Salicornia herbacea L. powder substitute for mungbean starch.

Salicornia herbacea L. is an annual herb that grows in salt marshes and salt fields along the seashores. It is also commonly used as a folk remedy in Korea. The objective of this study was to investigate the beneficial effects of Salicorrnia herbacea L. (SH) hot water extract on obesity. Five-week old male Sprague-Dawley rats (n=36) were divided into two groups and provided either a normal fat diet (11.5% fat from kcal) or a high fat diet (40.5% fat from kcal) for 6 weeks to induce obesity. Then, rats were blocked into six groups of six mice each and provided either a diet containing SH (0.5% of diet; g/kg) or a normal diet for another 6 weeks. Final body weights were significantly reduced when rats were fed SH among the high fat diet groups (HNS and HHS). Serum triglyceride concentrations significantly decreased in every group provided SH. HDL-cholesterol concentrations significantly increased in SH-fed groups among the high fat diet groups. Further, atherogenic index significantly decreased when rats were fed SH diet (HHS). There were no differences in LDL-cholesterol between the high fat diet groups, and glucose concentrations decreased when rats were fed SH diet (HNS). These results indicate that dietary intake of Salicornia herbacea L. hot water extract might have beneficial effects on obesity by reducing body weight, fat weights, and improving blood lipid profile.

Purpose: The objective of this study was to examine whether Hamcho freeze-dried powder and Hamcho freeze-dried nano powder have an anti-obese effect on high fat diet-induced obese rats. Methods: Sprague Dawley rats were divided into 6 different groups, each of which was bred for 8 weeks with a different experimental diet: normal diet group (NC), high fat diet group (HFC), high fat diet + 2% Salicornia herbacea L. freeze-dried powder group (2% HS), high fat diet + 5% Salicornia herbacea L. freeze-dried powder group (5%HS), high fat diet + 1% Salicornia herbacea L. freeze-dried nano powder group (1% HSN), high fat diet + 2% Salicornia herbacea L. freeze-dried nano powder group (2% HSN). Results: The 5% HS group showed a weight loss effect in body weight, liver and adipose tissue by reducing the amount of dietary intake and food efficiency ratio. In addition, the 5% HS group showed a significant reduction of serum leptin concentration, while having a beneficial effect on the improvement of lipid metabolism such as increase the serum concentration of adiponectin. However, Hamcho freeze-dried nano powder did not show a weight loss effect. Conclusion: Overall data indicated that Hamcho seemed to have anti-obesity effects. In particular, consumption of 5% Hamcho freeze-dried powder might have beneficial effects on body weight, serum adiponectin level, and lipid profiles since it led to reduced body weight and growth of adipose tissues by suppressing dietary intakes. However conduct of further research studies is needed for analysis of active components and biochemical action mechanism of Hamcho.

The purpose of the present study was to investigate the effect of enzymatic hydrolysate (extract) of Salicomia herbacea L. (Korean name: Hamcho) on antioxidative defense system in rats fed high cholesterol diet. Rats were divided into six experimental groups which are composed of normal diet group, normal diet group supplemented with 2% Hamcho extract, high cholesterol diet group, high cholesterol diet groups supplemented with 1%, 2% and 4% Hamcho extracts. The activity of serum glutamate oxaloacetae transaminase in rats was not different among all experimental groups, while the activity of glutamate pyruvate transaminase in groups supplemented with Hamcho extract was significantly lower than that of high cholesterol control group. Supplementation of Hamcho extract (SHE) to the high cholesterol fed rats resulted in increased activities of hepatic superoxide dismutase and glutathione peioxidase. However, there was no significant difference in the activity of hepatic catalase among all experimental groups. SHE also resulted in decreased levels of hepatic thiobarbituric acid reactive substances and mitochondrial carbonyl values. Those effects were higher to some extent in 2% and 4% Hamcho extract groups than those of high cholesterol control group. These results suggest that enzymatic hydrolysate of Hamcho may reduce oxidative damage by activation of antioxidative defense system in rats fed high cholesterol diets.

Male Sprague-Bawler rats were blocked into four groups which were normal rats fed control diet (NC) diabetic rats fed control diet (DC), normal rats fed Hamcho powder diet (NH), and diabetic rats fed Hamcho powder diet (DH). Diabetes was induced by single injection of streptozotocin (60 mg/kg B.W. i.p.). The animals were fed ad libitum for 5 weeks. Malondialdehyde (MDA), glucose 6-phosphtase (Gspase), glutathione S-transferase (GST) glutathione Peroxidase (GPx), and glutathione reductase (GR) activities were measured in the homogenates of liver and kidney, and total lipid, total cholesterol, triglyceride, and HDL-cholesterol concentrations in the blood serum. Food and water intakes were markedly higher in diabetic groups than those of normal groups and were not significantly decreased by Hamcho powder supplementation, But, FER (Feed efficiency ratio) of DH Brood was higher than that of U group. Total cholesterol level of DH group was decreased in the second and third week, and the weekly change of blood sugar was also decreased in the 5th week. Dietary Hamcho intake showed 41.2% of hypoglycemic effect in diabetics rats. Levels of total lipid and triglycerides of DH group were lower than those of DC group. Hepatic GR activity of DH group was higher than those of other groups. However, renal GR activity was lower than those of other groups. Hepatic G6Pase activity was significantly high in DH group and reduced by Hamcho powder supplementation. GST was reduced by Hancho diet in diabetic rats. In conclusion Hamcho supplementation decreased serum lipid and glucose concentration in STZ-induced diabetic rats and this effects of Hamcho might exert antidiabetic effect of Hamcho powder diet.

The present study was undertaken to investigate the hypoglycemic effect of Hamcho yogurt fermented by lactic acid bacteria containing Hamcho (Salicornia herbacea) extract powder in streptozotocin(STZ)-induced diabetic rats for 3 week period. The Hamcho yogurt given to the STZ-diabetic rats had significant effect in lowering the serum glucose concentrations and food intakes compared to the STZ-diabetic rats. The Hamcho yogurt administration increased the tolerance to oral glucose loading in the STZ-diabetic rats. The Hamcho yogurt and yogurt given to the STZ-diabetic rats were significantly decreased the serum total cholesterol concentration and the atherogenic index. Based on the beneficial effect against the blood glucose and cholesterol levels, we suggest the Hamcho yogurt can be used as functional food for the hypoglycemic and hypocholesterolemic effects.

In Korea, the aerial parts of the halophyte Salicornia europaea, known as hamcho, are used in salads in April–June and in oriental medicine in September–October In this study, with the aim of developing functional foods to aid blood circulation, hot water extract (HWE) and ethanol extract (EE) were prepared using hamcho harvested from the fields of Shinan, Jeonnam, Korea on 5th April (HWE-04, EE-04), 5th July (HWE-06, EE-06), 5th August (HWE-08, EE-08), 5th September (HWE-09, EE-09), and 5th October (HWE-10, EE-10), and their antioxidant and antithrombosis activities were evaluated. Among the HWEs, HWE-10 showed the highest concentration of total polyphenols and total flavonoids (22.4 and 17.6 mg/ml, respectively), and EE-09 had the highest concentration among the EEs (20.1 and 19.3 mg/ml, respectively). Among the HWEs and EEs, HWE-08 and EE-08 had the highest total sugar and reducing sugar content. In the antioxidation assay, HWE-10 and EE-09 showed strong reducing power, as well as DPPH, ABTS, and nitrite scavenging activities. The calculated RC₅₀s of EE-09 against DPPH, ABTS, and nitrite were 578, 277, and 68.8 μg/ml, respectively. The antithrombosis activity assay revealed that HWE-04, HWE-06, EE-04, and EE-06 had anticoagulation activity against coagulation factors and that HWE-08, HWE-09, EE-08, and EE-09 expressed strong thrombin inhibitory activity, which was comparable to the antithrombosis activity of aspirin. In addition, EE-06 and HWE-08 exhibited strong aggregation inhibitory activities against human platelets. The results suggest that extract from hamcho harvested in particular periods and prepared using a defined solvent has strong potential as a novel food ingredient and an antioxidant and antithrombosis agent.
