Durian seed starch-nanostructured-based fillers modification to enhance film appearance

Abstract. Durian seeds (Durio zibethinus Murr) are frequently discarded, adding to biomass waste. This research presents a green, economical, and high practicality approach for the fabrication of durian seed starch nanoparticles (DSS-NPs) derived from durian seed (Durio Zibethinus Murr) employing high pressure homogenizer to enhance its visual properties of film in sustainable applications. DSS-NPs suspension films were developed, and non-nanoparticle durian seed starch (DSS) suspension film was used as comparison. Morphological and structural aspects, including thickness and transparency of the suspension films were assessed. Thickness measurements for DSS and DSS-NPs films were recorded as 0.199 mm and 0.125 mm, respectively. The transparency of film revealed that it increased in DSS-NPs film, exhibiting higher absorbance values compared to DSS film. This indicated that DSS-NPs films exhibited enhanced compatibility in terms of morphology and appearance when compared to non-nanoparticle film which suggests significant potential for the application of DSS-NPs in diverse fields such as packaging materials and biomedical applications.
