| Popis: | Seaweed is one of the marine-biota that is widely known for its uses, one of them is in the food functional. Functional food is a program that promotes a healthy diet so that it can prevent a disease when consuming food. With functional food, daily eating patterns can be maintained and also the content of the food consumed daily has a good effect on the body. It is known that in seaweed, especially brown algae (S. crassifolium), it contains antioxidants and other compounds that are good for the health. In this study, phytochemical content and proximate composition was evaluated in S. crassifolium. Including total flavonoid content and total phenolic content, antioxidant capacity both of DPPH and ABTS assay used three type of solvents such as Ethanol, n-Hexana, and ethyl acetate for comparable the best solvents. Also, proximate analysis to determine the content of moisture content, crude fat content, crude protein content, and carbohydrates content. The results showed that n-Hexana and ethyl acetate solvents were significantly than ethanol. Which mean both of them had highest values of total flavonoid content (TFC), total phenolic content (TPC), and antioxidant activity of DPPH radical scavenging activity and ABTS radical scavenging activity. The results of chemical composition in proximate compounds showed that S. crassifolium was suitable to be candidate of functional food. |
