Overview

Experimental study reveals enhanced opacity and reduced water solubility in cassava starch sheets loaded with tucumã oil microparticles, suggesting potential for active food packaging.

Key Points

To evaluate the impact of incorporating free and microencapsulated tucumã oil on the physical, optical, and mechanical properties of extruded cassava starch sheets.
Extruded cassava starch sheets were formulated with pure tucumã oil or tucumã oil microparticles produced by spray drying (gum arabic wall), spray chilling (vegetable fat wall), or a combined method.
Assessed sheet physical characteristics, water solubility, mechanical behavior, and microscopic morphology using scanning electron microscopy.
Enrichment increased sheet opacity to 11.6–25.3% (compared to 6.3% in controls) and imparted a yellow coloration with a hue angle near 90°.
Additives reduced water solubility from 27.11% in control sheets to 24.67–25.54% in enriched sheets, with all sheets displaying thicknesses between 1.3 and 1.8 mm.
Scanning electron microscopy demonstrated that large combined spray-dried and chilled particles introduced structural discontinuities, decreasing tensile mechanical strength.
