The Effect of Sonication Time on Physicochemical Profiles of the Nanocalsium from Snake-Head Fish Bone (Channa striata)

Abstract

Abstract Snake-Head Fish bone is one of the fishery wastes that is potentially used as the raw material for calcium supplement products. In order to make the calcium products easily absorbed and utilized rapidly by human body, supplement products need to be made in nano form. The aims of this study were to determine the effect of the sonication time in the production of Snake-Head Fish bone nano calcium on the physical profile of the resulted nano calcium, and to obtain the best sonication time. The development of nanocalcium utilized sonication method with 405 Powersonic Ultrasonic Cleaner. The result showed that the best particle size distribution was found on 45 minutes sonication treatment which was 842.3 nm with the highest particle size ranging from 461,6 to 487,5 nm. The average value of the polydispersity index is 1.527. The yield of nano calcium produced from whole fish is 1.331%. The resulting nano calcium has an average white degree of 86.622% and average density of 0.73 g / ml. Some other mineral content also showed a not significant difference.
