소타와트 벤자쿨 교수의 연구실은 수산물 가공 및 품질 유지 기술에 중점을 두고 있으며, 특히 생선 폐기물의 효소적 수분을 통한 고부가가치 제품 개발과 자연소재 기반의 신선도 유지 기술을 핵심 연구 방향으로 삼고 있습니다. 단백질 분해 효소의 최적 조건 설정, 자가분해 반응에 의한 품질 저하 메커니즘 규명, 그리고 라이포좀 기반 생체활성물질 안정화 기술까지 수산물의 전주기 품질 제어를 위한 종합적 접근을 펼치고 있습니다. 특히 자연계 보존제와 기능성 소재 개발을 통해 기능성 식품 및 영양보충제 응용에 기여하고자 합니다.

Alcalase and Neutrase showed optimum activity against Pacific whiting solid wastes (PWSW) at pH 9.5, 60 °C and pH 7.0, 55 °C, respectively. Alcalase had a higher proteolytic activity than Neutrase. Enzyme concentration, reaction time, and waste/buffer ratio significantly affected the hydrolysis and nitrogen recovery (NR) (p < 0.05). Optimum conditions for PWSW hydrolysis were 20 AU Alcalase/kg, 1 h reaction time, waste/buffer ratio of 1:1 (w/v). Correlation between the degree of hydrolysis (DH)
ABSTRACT No changes in actomyosin Ca 2+ ‐, Mg 2+ ‐, or Mg 2+ ‐Ca 2+ ‐ATPase activities were observed during iced storage of Pacific whiting fillets, but Mg 2+ ‐EGTA‐ATPase increased with a loss of Ca 2+ ‐sensitivity. Surface hydrophobicity of actomyosin increased substantially within 2 days, but not total sulfhydryl (SH) content. During longer storage, the SH content decreased gradually, but surface hydrophobicity remained constant. Autolytic degradation products increased in fish muscle with st
