Coffee is a popular drink today. One of the coastal resources that can be processed into coffee-like products (analog coffee) is the mangrove fruits Rhizophora mucronata . The fruits of R. mucronata were reported to contain antioxidant substances that can support human health. This study aimed to characterize analog coffee products from the fruit of R. mucronata . The fruits were collected from Miulu village, Sangihe Islands, North Sulawesi. Mangrove fruits were soaked in a 2% lime solution for 72 hours and dried at 60 °C. Then it was roasted at 116-118 °C for 40 minutes, and the sample was ground until it resembled coffee grounds. The findings revealed that the water content of analog coffee was 4.14 ± 0.14%; ash 4.97 ± 0.02%; protein 14.38 ± 0.02%; fat 12.26 ± 0.08%; carbohydrate 63.67 ± 0.09%, energy 422.58 ± 1.01 kcal, caffeine 1.20 ± 0.00%, tannins 808.21 ± 2.02 mg/kg, and antioxidant capacity IC 50 131.28 ± 0.44 μg/mL. Furthermore, the analysis of compounds using GC-MS from the coffee analog of R. mucronata fruits was dominated by cis-9-Hexadecenal (50.95%) and 9-Octadecenal, (Z)-(33.97%). These research findings provide that analog coffee from the R. mucronata fruits has the potential to become a coffee-like product as a functional drink.
