Characteristics of Young Mangrove ( Sonneratia alba) Leaf Extract as A Biosalt Preparation

Abstract

Mangrove (Sonneratia alba) leaves contain bioactive compounds, macro and micro minerals, and NaCl content. However, the potential of the young mangrove leaves has not been explored. This research aimed to determine the characteristics of young mangrove leaf extract as a biosalt preparation. The sample used in this research was young mangrove leaves extracted using aquadest with 1:5 ratio. The parameters were tested for yield, moisture content, ash content, the mineral content of Natrium and Kalium, Na:K ratio, and NaCl content. The results showed that the biosalt characteristics of the mangrove leaf extract consisted of a brown appearance with a salty flavor, 6.96% yield, 5.07% moisture, 36.59% ash, 1.27 Na:K ratio, and 19.53% NaCl. Based on the NaCl content, the resulting biosalt required the dietary salt quality standard according to Standard National Indonesia of dietary salt.
