  • 톳으로부터 HPH를 이용해 식품에 적용 가능성이 있는 가식성 필름을 제작할 수 있었다. HPH 처리 압력의 증가는 필름의 강도와 깨짐성을 증가시켰고, 단면이 조밀하고 균일한 필름을 형성시켰다. HPH의 처리 횟수의 증가 또한 필름의 단면을 조밀하게 하였다. 개발된 톳 필름은 보고된 많은 다른 생고분자 필름들에 비해 상대적으로 강도, 깨짐성, 그리고 수분 저항력이 낮아 코팅 또는 롤을 비롯한 필름 형태로 건조 식품 또는 중간 수분 식품에 적용될 수 있는 가능성을 보여주었다.

  • The edible sargasso seaweed hijiki Sargassum fusiforme is known to have high concentration of arsenic, which is a threat to human health, particularly due to inorganic arsenic. In this study, various methods were used to remove inorganic arsenic from steamed hijiki concentrate. The highest concentration of arsenate [As(V)] in both raw and processed hijiki during steamed hijiki manufacturing process was within the range of 8.213-14.356 mg/kg, and it is a potential source of inorganic arsenic, which can result in re-contamination and cause environmental pollution. The removal efficiencies of the various removal methods were within the range of 57.3-83.4%, and 19.0% reduction was achieved using activated carbon and alginate bead. Further, activated carbon showed the best adsorption effect of inorganic arsenic. Therefore, we suggest that activated carbon is a suitable efficient method for removing inorganic arsenic and has low operational costs in field applicability.

  • Several pretreatment methods have been developed to reduce the inorganic arsenic, which is known to be highly harmful to humans, among various arsenic species present in hijiki and rice. The pretreatment methods were selected and developed as methods that can be non-harmful even after treatment and easily applied. Hijiki was applied by two methods. One was soaking in water at room temperature for various durations and the other was boiling of it in water for a short period of time. Rice was soaked in water with different rice-to-water ratios for various durations. The most effective method that reduced the inorganic arsenic in hijiki was to repeat parboiling for 5 minutes twice, which led to 79% reduction of the inorganic arsenic in it. In the case of rice, soaking for 24 hours at the ratio of 1:5 (rice:water) resulted in 51% reduction of inorganic arsenic in rice.

  • 본 연구는 비소 함량이 높은 해조류(10-60 mg/kg) 중 무기비소 함량이 높은 톳을 대상으로 총 비소 함량 측정 및 비소종 분리, 분석을 실시하였으며, 그 결과를 바탕으로 PTWI와 비교하여 위해성 평가를 실시하였다. 전국 10곳의 지역에서 총 30종의 시료를 구입하여 ICP-MS로 총 비소 함량을 측정한 결과 건조시료를 기준으로 평균 45.65${\pm}$21.17 mg/kg(생물기준; 3.63${\pm}$2.19 mg/kg)의 함량을 보여 다른 나라의 여러 연구결과와 비교해 볼 때 상대적으로 낮게 확인되었다. HPLC-ICP-MS를 이용하여 분리, 분석된 톳의 주요 비소화학종은 상대적으로 독성이 강한 무기비소로 평균함량이 As(V) 40.36 mg/kg, As(III) 0.37 mg/kg으로 전체 비소함량의 88.6%를 차지하였다. 그러나 무기비소함량이 가장 높게 확인된 시료(생물기준; 9.19 mg/kg)를 대상으로 톳의 위해성을 JECFA의 PTWI와 비교해 볼 때 6.1%로 낮은 수준이었다. 따라서 연 평균 0.1 g의 톳을 섭취하는 한국인에게서는 14.0 g/day(98.3g/week) 이상의 톳을 지속적으로 먹지 않는 이상 톳의 섭취에 따른 위해 가능성은 미비하여 안전한 수준으로 판단된다.

  • The effects of sea tangle, sea mustard, hijiki, and glasswort were investigated based on the proximate composition, salinity, cooking loss, emulsion stability, pH, color, texture profile analysis, apparent viscosity, and sensory characteristics of reduced-salt (NaCl) meat batter and frankfurters. The moisture content, salinity, lightness of the meat batter and frankfurter, hardness, gumminess, and chewiness of the reduced-salt frankfurters with sea weeds were lower than the control without seaweed (p<0.05). The protein content, springiness, and cohesiveness of the reduced-salt frankfurters were not significantly different among the treatments (p>0.05). The moisture content, salinity, cooking loss, lightness, redness, hardness, gumminess, and chewiness of treatments with sea tangle and with sea mustard were lower than the control (p<0.05). Among the sensory traits, color was highest in the control (p<0.05). The flavor was also highest in the control. The treatments with sea tangle and with sea mustard samples had high tenderness, juiciness, and overall acceptability scores similar to the control (p<0.05). The results of this study show that the combination of low-salt and seaweed in the formulation successfully improved reduced-salt frankfurters, improving sensory characteristics to levels similar to the regular salt control (1.5%).

  • In the present study, exposure to heavy metals by consumption of edible seaweeds (green laver, laver, hijiki, sea tangle, and sea mustard) was assessed based on their concentrations of lead (Pb), cadmium (Cd), arsenic (As), and mercury (Hg). The mean of heavy metal concentrations were 0.006-0.023 mg/kg for Pb, 0.037-0.156 mg/kg for Cd, 1.117-15.928 mg/kg for As, and 0.008-0.021 mg/kg for Hg. In multivariate analysis, the correlations were high between Pb levels in sea mustard, Cb levels in laver, and As and Hg level in Hijiki. However, the estimated daily intake and target hazard quotient (THQ) of the heavy metals in edible seaweeds were below their approved limits suggesting no health risks associated with seaweed consumption by Koreans.
