불가사리를 이용하여 제조한 칼슘보충제의 이화학적 특성 = Physiochemical Characteristics of Calcium Supplement Manufactured using Starfish

다국어 초록 (Multilingual Abstract)

For developing calcium supplement from the harmful marine organism starfish, the physiochemical property of the powdered starfish skeletal plate and the hydrolysis condition of the starfish digestive enzyme were studied. The optimal hydrolysis condition of the starfish digestive enzymes was at 55℃ for 12 h. The bulk densities of the powdered starfish skeletal plates of Asterias amurensis and Asterina pectinifera were 1.1±0.0 and 1.2±0.0 g/cm3, respectively. As for the median size, the values were 10.738 and 11.799 μm, respectively. According to the added concentration of sodium polyacrylate, the dispersibility rate of the powdered starfish skeletal plate was shown to be 6h at 0.0%, 3 days at 0.1%, 20 days at 0.2%, and until 30 days at 0.4%. The elementary composition of the powdered starfish skeletal plates from A. amurensis and A. pectinifera mainly consisted of calcium, and it formed 98.95 and 98.52% of the powdered starfish skeletal plates, respectively. The results of the X-ray diffraction (XRD) analysis showed that they were present in the form of CaCO3. Based on these results, it is suggested that starfish skeletal plate can be utilized as a functional material for a calcium supplement.
