Abstract:
Polyscias fruticosa (L.) Harms is a plant possessing high pharmacological properties. With the aim of enhancing the utilization value of this plant, this study introduces the initial development of a production process for a herbal beverage utilizing saponin-rich vacuum concentrates derived from P. fruticosa leaves. The research results established an optimal blending ratio of concentrate/water (v/v) at 1:11; sucrose content at 10 (g/100ml); citric acid content at 0.1 (g/100ml); and a pasteurization regime at 65°C for 3 minutes. The final product achieved a "Good" sensory classification, a Total Saponin Content (TSC) of 0.364 ± 0.05 (mg/ml), and complied with microbiological criteria according to QCVN 6-2:2010/BYT for non-alcoholic beverages.
