To investigate Oiji (traditional Korean cucumber pickles) with reduced sodium content based on the use of saline foods as a salt substitute, Oiji was prepared using glasswort powder (Salicornia herbacea L.), and its physicochemical properties and sensory evaluation were examined. The moisture content of Oiji was shown to be higher in those to which glasswort powder had been added compared to the control without addition of glasswort powder, and Oiji with 40% glasswort powder substitute showed the highest pH and lowest acidity, resulting in slow progression of fermentation. The salinity of Oiji among those containing glasswort powder substitute was significantly higher with increasing level of glasswort powder. The sodium content of Oiji was significantly reduced as addition of glasswort powder increased. The L value of Oiji decreased with increased addition of glasswort powder, whereas the a value was highest in the control. The hardness of Oiji was higher in the control than in Oiji containing glasswort powder. Taste acceptance was highest for Oiji with 20% glasswort powder substitute, whereas acceptance of appearance was higher for Oiji with 10% glasswort powder substitute. Flavor and texture acceptance was higher for the control. In the attribute difference test, significant differences were found in brownness, off-flavor, salty taste, and sourness. Based on the findings, 10-20% substitution of salt with glasswort powder did not significantly lower overall acceptance compared to the control while salinity of Oiji was maintained. Therefore, the potential production of low-sodium Oiji has been verified.

 ,  , Occurrence of Scrobipalpa salinella (Zeller) was investigated on glasswort in Shinan, Jeonnam and Kimjae, Jeonbuk from 2010 to 2011. The occurrence of S. salinella observed four times in a year. Adult stages of S. salinella in two areas occurred from mid-April to late September. The peak times of 1st, 2nd and 3rd generation adults of S. salinella was observed on early May, mid-June, late July (in Kimjae) to early August (in Shinan) and early September, respectively. And larval stages of S. salinella occurred from late May to late August. The peak times of development of 1st, 2nd and 3rd generation larvae of S. salinella was observed on mid-June, mid-July and mid-August, respectively. However, the 4th generation larvae began to occur in mid-September but didn’t damage in glasswort. Among the distances from the bank of glasswort field (3, 6, 9 m) and periods of damage (Jun. 16, Jul. 7, Aug. 12), larval density in 3 m distance from the bank in 1st damage season (Jun. 16) was high which resulted to severe damage. Damage of 2nd and 3rd generation larvae was progressed both density of larvae and levels of damage.

퉁퉁마디를 기능성 식품소재로 이용하기 위한 자료로 전남지역(해남 황산면, 신안 증도면, 영광 염산면)의 퉁퉁마디를 6월부터 10월까지 채취하여 구성아미노산, 유리아미노산, 폴리페놀함량, 전자공여능, SOD 유사활성을 조사하였다. 그 결과, 3지역 퉁퉁마디의 구성아미노산은 6월부터 9월까지는 Glutamic acid, Aspartic acid, Leucine 순으로, 10월에는 Glutamic acid, Aspartic acid, Arginine

본 실험은 퉁퉁마디의 에탄올 추출조건에 따른 당도, 수율, 전자공여작용 및 총 페놀화합물 함량에 대해 반응표면 분석법을 이용하여 추출조건을 최적화하였다. 중심합성계획에 따라 용매에 대한 시료비(/100 mL), 추출온도() 및 에탄올 농도()를 달리하였을 때 반응표면 회귀식의 R2는 당도, 수율, 전자공여작용 및 총 페놀화합물 함량에서 각각 0.7866(p/100 mL, 추출온도 , 에탄올 농도 로 나타났다. 최적 추출조건범위내의 임의의 조건

This study was conducted to investigate the transplant possibility of glasswort (Salicornia herbacea) into new reclaimed land. The glassworts were transplanted into new reclaimed land at May 2000, and at next year we investigated the plant growth, yields, and the amounts of mineral elements of newly grown plants at new reclaimed land. The plant height of April was 8.5 cm, but at June that increased as 35.9 cm and the lateral shoots number were also increased. The total yields was 976.4g/m2 in fresh weight, and dry weight was 207.5g/m2. We measured the mineral element contents at April, May, and June, respectively. Na, Mg, and Ca of shoots were always more accumulated than that of root, and the amount of mineral contents trends was not affected by season. While P and Zn was reverse.

퉁퉁마디의 약리효과를 규명하기 위하여 퉁퉁마디 추출액을 실험용 동물에 4주간 섭취시키는 실험을 하였다. 대조군은 4주간 145.5g의 체중이 증가한 반면 퉁퉁마디 추출액 20% 투여군은 128.4g의 체중이 증가하였다. 체중증가율은 대조군에서 107.8%이였으며 퉁퉁마디 20% 투여군에서는 95.1%를 보여 대조군에 비해 체중 증가율이 최대 11.8% 낮았다. 혈중 총단백질 함량과 알부민 함량은 대조군과 실험군간 유의적인 차이가 나지 않아 체중 감소에 따른 실험군간의 영양상태는 차이가 없는 것으로 판단된다. 간기능활성도 측정을 위한 GOT와 GPT 값은 각각 126.7~134.1 U/L, 41.1~46.7 U/L로 나타났다. 대조군에 비해서 퉁퉁마디 추출액 투여군의 혈중 콜레스테롤은 유의적(p〈0.05)으로 현저하게 감소하였고 HDL-콜레스테롤은 유의적(p〈0.05)으로 증가하는 경향을 보였다. 대조군에 비해서 퉁퉁마디 추출액 투여군의 혈중 총지질함량과 중성지질함량은 유의적(p〈0.05)으로 감소하는 결과를 얻을 수 있었다. 이상의 결과에서 퉁퉁마디 추출액은 동맥경화, 고지혈증, 지방간 등의 예방효과 뿐만 아니라 체중증가 억제에도 효과가 있을 것으로 판단된다.
