Preparation and characterization of starch aerogels loaded with senna alata (l.) roxb leaves extract

From this study, an improved approach for production and characterization of starch aerogels infused with extracts from Senna alata (L.) Roxb leaves. Tapioca starch aerogels were synthesised at concentrations of 10 wt% and 15 wt%. The leaves of Senna alata were subjected to Soxhlet extraction using ethanol as the solvent. The plant extracts were subsequently integrated into starch aerogels with a starch content of 15 wt% at concentrations of 1% and 3%. The physical, chemical, biological, and thermal properties of the loaded starch aerogels were assessed using scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy, antimicrobial disc diffusion tests, and thermogravimetric analysis (TGA). The SEM investigation indicated the presence of porous structures inside the starch aerogel matrices. The FTIR analysis verified the existence of starch and extracts in the aerogel composites. The aerogels, which were filled with substances, exhibited antibacterial properties against E. coli bacteria. The thermogravimetric analysis (TGA) data demonstrated that the aerogels remained thermally stable up to a temperature of 250°C. The results demonstrate the successful synthesis of starch aerogels by using Senna alata extracts. These aerogels have the potential to be used as absorbent pads with antimicrobial properties in active food packaging. Additional testing is advised to examine the rate at which the extracts are released, in order to achieve controlled delivery in food systems.
