Abstract

 Antioxidants are natural compounds found in many fruits, as well as in Rhodomyrtus tomentosa. The research, Rhodomyrtus tomentosa will be processed in form of syrup. The results of the organoleptic test of syrup ranged from like to  very like by panelists. Determine the  physical and chemical properties on syrup Rhodomyrtus tomentosa were acidity value is 4,41, total acid is 0,003%, total dissolved solids 23,74^oBrix and sugar level of syrup is 21%.  The results of Vitamin C content analysis of 1.25 mg / 100 g. The syrup contains Fe 0.525 mg / L and Cu 0.220 mg / L. In the Rhodomyrtus tomentosa  syrup there is no lead (Pb), cadmium (Cd),  Mercuri (Hg), Arsenic (As) and  Stanum (Sn) metal.
