This study aimed to produce sustainable smart packaging based on cassava starch and a natural pH indicator (anthocyanin) by a twin-screw extrusion process. It also aimed to evaluate various anthocyanin concentrations (5, 10, 20) mg ATH per 100 g on selected sheet properties and the indication of pH changes. The incorporation of ATH generated sheets thicker (similar to 2.5x), less resistant at break (similar to 4.5x), less flexible (similar to 1.4x) and less rigid (similar to 4.5x). However, ATH did not affect the crystallinity profile. The thermoplastic starch sheets incorporated with 20 mg ATH/100 g showed the best behavior as a smart packing indicator of pH change in meat stored at 6 degrees C, with the higher variation of Delta E{*} and the most visually notable color change. Therefore, this work allowed producing sustainable smart packing by the large-scale method (extrusion), and it can expand the application of this type of material in the food industry. (AU)
