This study was designed to examine the effects of Salicornia herbacea L. (glasswort: GW) on the lipid peroxidation and mineral levels in diabetic rats. Diabetes mellitus was induced in male Sprague-Dawley rats weighing 200-220 g by an injection of streptozotocin (STZ) dissolved in a citrate buffer into the tail vein at a dose of 45 mg/kg of body weight. Sprague-Dawley rats were fed an AIN-93 recommended diet and the experimental groups were fed a modified diet containing 10% and 20% of glasswort powder for 4 weeks. The experimental groups were divided into 6 groups which consisted of normal (N)-control group, N-GW 10% and N-GW 20% treated groups, STZ-control, STZ-GW 10% and STZ-GW 20% treated groups. The rats' liver and muscle glycogen, liver and kidney protein, cholesterol and triglyceride (TG) in liver, malondialdehyde (MDA) in liver and kidney values were measured, along with the hepatic of chromium (Cr), iron (Fe), and zinc (Zn) content. The liver glycogen levels was significantly affected in N-GW 20% group among all the experimental groups. The liver MDA levels of the STZ-GW 10% and STZ-GW 20% groups were significantly lower than for the STZ-control group. There were significant differences between the N-control group and the STZ-control group in the hepatic of Zn levels. The hepatic of Cr levels in the N-GW 20% and STZ-GW 10% and STZ-GW 20% groups were significanly higher than for the each control groups. These results exhibited dose related effect of glasswort and it may have favorable influence on lipid peroxidation in the liver.

This study was designed to examine the effects of Salicornia herbacea L. (glasswort: GW) on the plasma blood glucose and lipid metabolites in diabetic rats. Diabetes mellitus was induced in male Sprague-Dawley rats weighing 200-220g by an injection of streptozotocin (STZ) dissolved in a citrate buffer into the tail vein at a dose of 45 mg/kg of body weight. Sprague-Dawley rats were fed an AIN-93 recommended diet and the experimental groups were fed a modified diet containing 10% and 20% of glasswort powder for 4 weeks. The experimental groups were divided into 6 groups which consisted of normal (N)-control group, N-GW 10% and N-GW 20% treated groups, STZ-control, STZ-GW 10% and STZ-GW 20% treated groups. The rats' body weights, aminotransferase activities and hematocrit (Hct) values were measured, along with plasma levels of glucose, protein, cholesterol, HDL-cholesterol, triglyceride (TG) and free fatty acids (FFA). The non-diabetic rats gained weight, while the diabetic rats lost weight. There were significant differences between the control group and the diabetic groups in the weight of the kidney, liver and pancreas. Asparate aminotransferase activity was lower in the non-diabetic control group compared to diabetic experimental groups, even though the difference was not significant. The plasma protein of N-GW 20% group was lower among all experimental groups but it was not significantly different. The blood glucose levels of the STZ-GW 10% group and STZ-GW 20% group were significantly lower than for the diabetic-control group. There were no significant difference of cholesterol levels among diabetic groups. The normal rats of 20% glasswort group in FFA and TG levels showed significant changes among all groups. These results exhibited dose related effect of glasswort and it may contain antihypoglycemic compounds.

This study performed physicochemical characteristics and sensory tests on brown sauce with different Salicornia herbacea L. (saltwort) content to find the best brown sauce recipe with saltwort. Moisture content increased with greater saltwort extract content. There was significant (p<0.001) pH difference with saltwort content. There was also significant (p<0.001) sweetness difference in the samples and sweetness increased with greater saltwort content. Viscosity measured at $20^{\circ}C$ and $60^{\circ}C$ was significantly (p<0.001) lower with greater saltwort content. The brightness of brown sauce containing saltwort extracts significantly (p<0.001) increased with greater saltwort content and its redness and yellowness usually decreased. SPS4 with the greatest saltwort content showed the highest value of 4.25% and DPPH radical removal increased significantly (p<0.001) with greater saltwort content. In the sensory test, the color value was lowest at 4.82 with BSL1 and the flavor value was lowest at 5.00 with BSL0, the control group. The taste and the flavor values were highest with BSL2 with 2% saltwort content. Overall acceptance was highest with BSL3, the brown sauce with 3% saltwort content, at 6.09. As a result, it was concluded that the brown sauce with 3% saltwort content was most suitable. Therefore, this study concluded that saltwort with various functions could be used for food and may be used to replace salt and have other functions in brown sauce, a popular sauce consumed in Korea.

The objective of this study was to evaluate the quality characteristics of sun-dried Hanwoo beef jerky added with Salicornia herbacea (SH). Sliced Hanwoo beef shank were marinated and sun-dried at $28-30^{\circ}C$, relative humidity (RH) 30-35% for 3.5 h. The physicochemical and microbiological traits of the Hanwoo beef jerky were analyzed during the aerobically packaged storage at $25^{\circ}C$. The water activities of beef jerky with 0.5% and 1.0% SH were lower than those of the control at 0 d (p<0.05). The pH values of beef jerky with SH were significantly higher than those of the control (p<0.05). The beef jerky with SH and ascorbic acid showed significantly lower TBARS values than the control (p<0.05). The beef jerky with SH showed a significantly lower redness ($a^*$) than the control (p<0.05). Total plate count (TPC) of beef jerky with 1.0% SH was significantly lower than that of the control during the storage of 20 d (p<0.05). Yeast/mold was detected in the control and beef jerky with SH after storage periods of 10 and 20 d, but was not detected in jerky with ascorbic acid. With regard to the sensory properties, beef jerky with SH showed significantly greater flavor scores than the others (p<0.05). The result shows that SH powder can be used to increase the sensory quality and microbial safety of beef jerky.

The antioxidant activities of water ($H_2O$) and ethanol (EtOH) extracts from hamcho (Salicornia herbacea L.) juice and cake prepared by enzymatic treatments were evaluated by in vitro assays against DPPH, superoxide, and hydroxyl radicals. Among the $H_2O$ and EtOH extracts from five different carbohydrases treated, the EtOH extract from viscozyme-treated hamcho cake had higher yield and phenolic content, and exhibited the strongest radical scavenging activity against DPPH ($IC_{50}=186.91\;{\mu}g/mL$), superoxide ($IC_{50}=87.54\;{\mu}g/mL$), and hydroxyl radicals ($IC_{50}=367.07\;{\mu}g/mL$). Antioxidant assay-guided fractionation and purification of the EtOH extract led to isolation and identification of five phenolic compounds, procatechuic, ferulic and caffeic acids, quercetin, and isorhamnetin. Most of these phenolic compounds exhibited considerable DPPH, superoxide, and hydroxyl radical scavenging activities, and in particular, caffeic and ferulic acids had stronger superoxide and hydroxyl radical scavenging activities than the well-known antioxidant radical scavenger, (+)-catechin (p<0.05). Quercetin and isorhamnetin were the primary compounds responsible for the strong antioxidant activity in the EtOH extract of the viscozyme-treated hamcho cake. Meanwhile, these five phenolic compounds were detected in the EtOH extract of the viscozyme-treated hamcho cake at the following levels (dry base of hamcho); procatechuic acid (1.54 mg%), caffeic acid (6.87 mg%), ferulic acid (8.45 mg%), quercetin (12.63 mg%), and isorhamnetin (6.65 mg%). However, three of these phenolic compounds (procatechuic, caffeic acid, and ferulic acids) were detectable in the $H_2O$ extract of viscozyme-treated hamcho juice. These results suggest that the EtOH extract of viscozyme-treated hamcho cake may be a potential source of natural antioxidants.

함초(Salicornia herbacea)는 염습 지대에서 자생하는 명아주과에 속하는 일년초 식물로서 우리말로는 퉁퉁마디라고 불리우며, 식용과 약용으로 이용되고 있다. 건조된 함초로부터 열수 추출을 하여 조추출물(CSP)을 얻었으며 조추출물을 한외 여과하여 다당체(SP1)를 얻었다. 이렇게 얻은 조추출물과 다당체에 대해 streptozotocin (55 mg/mL/kg)으로 유발한 당뇨 쥐를 이용하여 정상 대조군(NC)과 당뇨 대조군(DC), 당뇨 조추출물군(DCSP), 당뇨 다당체군(DSP1)으로 분류하고 각각 조추출물과 다당체 2%를 6주간 공급하여 실험한 결과, DCSP군과 DSP1군에서는 대조군과 비교하여 혈당은 10%, 25%씩 감소하고, 중성 지방은 13%, 20%씩 감소하여 유의적인 수치를 나타내었다. 즉, 함초로부터 조추출물과 다당체를 획득하여 이들에 대한 항당뇨 실험을 한 결과, 조추출물과 다당체에서 혈당 저하와 중성 지방 저하의 효과를 보였는데, 조추출물보다 다당체에서 더 높은 활성을 보였다. 따라서 함초 다당체는 항당뇨 활성을 가진 바이오헬스 소재로 개발될 수 있을 것으로 기대된다.
