This study was conducted to ascertain the antioxidant properties of Hamcho (Salicornia herbacea L.) and as well as manufacture pettitoes using Hamcho as a natural antioxidant material for diverse applications. The DPPH radical scavenging activities of 25, 50, 100 mg/mL in methanol extracts from Salicornia herbacea L. increased significantly (p<0.05) to 12.8%, 21.6% and 39.1%, respectively. The total phenolic content was $38.58{\pm}4.25{\mu}M$ as tannic acid equivalent for 100 mg/mL of methanol extracts from Hamcho. FRAP value was $448.58{\pm}14.01{\mu}M$ as ascorbic acid equivalent in reducing power. To apply Hamcho to food as a natural antioxidant, pettitoes were prepared with added Hamcho. To manufacture pettitoes added with Hamcho, general quality characteristics of pettitoes added with 0%, 2%, 4% and 6% based on 100 g of pettitoes were determined. In conclusion, mineral components increased according to the added amount of Salicornia herbacea L. Crude protein showed the highest value with 2% added Hamcho. Overall, the addition of Hamcho led to hardening of the meat texture. As a result of measuring color in terms of brightness, redness, and yellowness with chromaticity, the L value (brightness) increased with added amount of Hamcho. There was no significant difference in redness or yellowness. As a result of the sensory evaluation of pettitoes according to addition of Hamcho, the group with 4% added Hamcho showed enhanced overall preference with improved flavor, taste and textural properties.

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 chemical compositions of amino acids, minerals, betaine, and polyphenolic compounds from Salicornia herbacea (Hamcho) according to harvest periods were analyzed. Changes of chemical characteristics in water and ethanol extracts from Hamcho were evaluated for titratable acidity, pH, soluble solid, and Hunter's color values. The antioxidative activity of water extract from Hamcho was also determined by DPPH $({\alpha},{\alpha}'-diphenyl-{\beta}-picrylhydrazyl)$ scavenging radical activity. Total polyphenolic compounds of Hamcho were shown the highest in August harvested by 201.6 ppm. The betaine of Hamcho water-extract was identified by high performance liquid chromatography (HPLC), which content was 0.248%, 0.269% and 0.204% in June, August, and October, respectively. Major compositional amino acids (mg%) were glutamic acid (582: 519: 664), proline (552: 471: 322), phenylalanine (480: 431: 424), aspartic acid (322: 297: 330), and arginine (282: 321: 483) in June, August, and October, respectively, and major free amino acids (mg%) were proline (9.7: 3.4), asparagine (6.7: 1.4), hydroxyproline (6.4: 2.8), valine (3.9: 2.5), arginine (1.7: 3.0) in June and August, respectively. Mineral contents (mg%) were Na (5,695: 7,536: 5,529), K (1,640: 963: 931), Mg (359: 428: 348), Ca (221: 234: 251), and P (207: 189: 259) in June, August, and October, respectively. Especially, K was high in June, Na and Mg were high in August, and Ca and P were high in October, respectively. DPPH scavenging radical activity was shown in the following order; 0.05% butylated hydroxytoluene (BHT)> August> June> October harvested Hamcho. The chemical components of polyphenolic compounds, betaine, amino acids and minerals were changed by harvest periods according to the growing season, and the highest concentrations of polyphenolic compounds and betaine of Hamcho were shown in August harvested.
