Abstract

This research aimed to determine the effect of maltodextrin concentration and drying time on the physicochemical characteristics and antibacterial activity of japanese bamboo leaf powder (Dracaena surculosa Lindl). This research was conducted from October 2023 to April 2024 at the Laboratory of Chemistry, Processing, and Sensory of Agricultural Products and the Laboratory of Microbiology and Biotechnology of Agricultural Products, Department of Agricultural Technology, Faculty of Agriculture, Universitas Sriwijaya. This research used the Completely Randomized Design (CRD) Factorial with 2 factors. The first factor was the addition of maltodextrin with 3 levels (5%, 10%, 15%), and the second factor was drying time with 3 levels (3 hours, 5 hours, 7 hours). The parameters observed in this study were physical characteristics (yield, color L* C* h*), chemical characteristics (moisture content and saponin qualitative), and microbiological characteristic (antibacterial activity). The results showed that maltodextrin concentration had a significant effect on yield, chroma, and hue, while drying time had a significant effect on yield, lightness, chroma, hue, and moisture content. The interaction of maltodextrin concentration and drying time significantly affected yield. The A2B1 treatment (10% maltodextrin concentration and 3 hours drying time) was the best treatment with the characteristics of japanese bamboo leaf powder: yield of 44.40%, lightness of 60.72%, chroma of 29.71%, hue of 107.23o, moisture content of 6.71%, clear zone area of Escherichia coli bacteria of 5.89 mm and clear zone area of Staphylococcus aureus bacteria of 9.60 mm.
