Abstract Soy protein (SP) was obtained from degreased soybeans which are discarded as an industrial waste around the world. Therefore, materials consisting of soy not only environmentally benign but also sustainable materials. We prepared SP − GPTMS composite by mixing and a silane coupling reagent, 3-glycidoxypropyltrimethoxysilane (GPTMS), demonstrated accumulation various aldehydes, such formaldehyde (HAld), acetaldehyde (AcAld), butyl aldehyde (BuAld), benzaldehyde (BnAld), As result, when were incubated in aqueous multi-component solution containing four these effectively accumulated aldehydes. The amounts aldehydes BnAld < BuAld AcAld HAld amount three times higher than that BnAld, had lowest amount. These results suggested indicated molecular selectivity for HAld. In addition, further increased under acidic conditions. Furthermore, according to IR measurements, HAld-accumulated showed formation hydroxymethyl groups. material due high electrophilicity low steric hindrance.

This study evaluates the potential of natural and thermally modified starches from Kazakhstan, including cassava, potato, wheat, corn, pea, rice, for production biodegradable films. Key physicochemical properties were analyzed using Fourier Transform Infrared Spectroscopy (FTIR), Differential Scanning Calorimetry (DSC), X-ray diffraction (XRD), Electron Microscopy (SEM), a Rapid Visco Analyzer (RVA). The results show that cassava starch, with highest magnesium content (43.07 mg/100 g) peak viscosity (1300 RVU), exhibits superior mechanical strength elasticity, making it ideal durable agricultural Corn high crystallinity moderate (1150 excellent stability long-term applications. In contrast, wheat rice starches, lower viscosities (750 650 RVU, respectively) biodegradability, are more suitable short-term eco-friendly Modification processes improved moisture resistance reduced retrogradation tendencies, particularly in corn starches. SEM analysis revealed have dense uniform surface structures, enhancing film durability flexibility. These findings highlight utilizing Kazakhstan’s starch resources localized production, reducing reliance on imports while promoting sustainable agriculture.
