Abstract

This study investigates the dry matter content, total carbohydrates, and fatty acid composition of Syzygium samarangense (Rose apple), a tropical fruit commonly grown in Southeast Asia. Samples were collected from a garden in Dhaka, Bangladesh, and analyzed for moisture, ash, fat, and carbohydrate content, as well as fatty acid composition. The dry matter content was determined to be 7.28%, with a moisture content of 92.72%, and ash content at 4.35%. The average fat content across samples was 0.29%. Gas Chromatography-Flame Ionization Detection (GC-FID) revealed that the predominant fatty acids were eicosenoic acid (25.59%), behenic acid (21.93%), and arachidic acid (19.16%). The total carbohydrate content was found to be 65 mgkg,-1 was confirmed through a modified Molisch test and calibration curve analysis. Glucose presence in the fruit was verified via thin-layer chromatography. These findings provide a comprehensive nutritional profile of Rose apple, contributing to its potential as a functional food with benefits in hydration, energy provision, and cardiovascular health. This research lays a foundation for future studies on the nutritional and health benefits of this underexplored tropical fruit.
