This research focused on formation of inclusion complexes to improve the stability of vanillin. The amylose in starch can act as a host molecule by forming a single helix known as V-amylose which has a hydrophobic channel. In this research, the starch was suspended in water (2.8% (w/v)) and was sonicated for 30 minutes. The mixture was subsequently heated at 180°C to dissolve starch. Vanillin dissolved in ethanol was then mixed with the starch solution at around 85°C. The concentration of vanillin was varied at 10%, 30% and 50% (w/w, based on the weight of starch). The resulting inclusion complexes were characterized by Fourier Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD), Thermogravimetric Analysis (TGA), and Scanning Electron Microscope (SEM). FTIR characterizations were conducted on starch, vanillin, physical mixture of starch-vanillin, and the inclusion complexes. The results showed there were differences on some vibration peaks between the physical mixture of starch-vanillin and the inclusion complex. The XRD results depicted different patterns of the diffraction peaks for the inclusion complexes compared to native starch and vanillin which showed that the starch-vanillin complexes were successfully formed.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Diffraction peaks,FT-IR characterization,Host molecules,Inclusion complex,Physical mixtures,Starch solutions,Vanillin,Vibration peak[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Inclusion complexes,Starch,Starch complexes,Starch-vanillin,Vanillin[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.4028/www.scientific.net/KEM.811.34[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
