RESUMO
Amorphophallus muelleri BI was included in the Araceae family, which is a type of tuber. It is a tuber with high potential due to its abundant bioactive compounds. Amorphophallus muelleri BI flour (AF) contains a high glucomannan and carbon compounds that serve as nutrients for probiotic bacteria. Although Amorphophallus muelleri BI thrives in Indonesia, its utilization rate in the country remains relatively low and haven't been any studies conducted regarding synbiotic powder from AF. The primary objective of this research is to develop a synergistic beverage enriched with varying concentrations of Amorphophallus muelleri BI as a prebiotic and LA as probiotic (synbiotic). The process starts with culture preparation, synbiotic drink process, synbiotic and microencapsulation, includes the examination of solubility, proximate analysis, calorie content, viability, and shelf life. Results showed that the proximate and solubility had no significant effect. Synbiotic drink powder from AF can be produced using spray dry technology. The highest LA growth was observed when augmenting the AF quantity at a 0.4% concentration, which can be seen from the viability parameter with a value of 7.29 log CFU/g. Samples shelf life at -21 and 3 °C with LA viability critical parameter was determined to be 4 days.
