Single-bulb garlic (Allium sativum L.) is a plant with various properties, such as anticancer, antibacterial, antihypertensive, and antioxidant. The processed product of garlic is black garlic which is made by fermenting garlic by heating at a temperature of 60-90°C within a few days. Formulated products in instant powder drinks can increase public consumption interest. This study aimed to formulate an instant powder functional beverage from single-bulb black garlic combined with rosella flower (Hibiscus sabdariffa L.) using the foam mat drying method. Egg white is used as a foaming agent and methylcellulose as a foam stabilizer. The formula consisted of single-bulb black garlic powder, rosella flower powder, powder combination of single-bulb black garlic, and rosella flower (30:70) and (50:50). The color, smell, taste, and water content of the four formulas have met the quality standard of SNI 01-4320-1996. DPPH free radical scavenging test with parameter IC50 showed that the combination powder of single-bulb black garlic and rosella flower (30:70) had higher antioxidant activity than the other combination (50:50). The consumer acceptance test on the combined instant powder formula showed that consumers preferred the combination powder of single-bulb black garlic and rosella flower (30:70).
