dc.description.abstractActive compounds play a critical role in the effectiveness of active packaging but are often vulnerable to degradation under harsh conditions, limiting their functionality. This study aims to develop a sago starch-based porous carrier designed to protect these compounds and enable their controlled release in active packaging applications. The combination of freeze thaw pre-treatment, ultrasonic, and enzyme (ft), resulted in significant formation of pore structures on the sago starch granule surface. The enthalpy of gelatinization decreases from 3.32 j/g for native samples to 2.98 – 3.13 j/g for treated samples due to pore formation. Thermogravimetric analysis showed a similar trend, with the native sample’s temperature dropping from 340 °c to 332 – 334 °c after modification. Increasing the surface area in ft samples significantly enhances water and oil absorption capacity by up to 37.04% and 108.74% respectively. Variations in pore formation significantly affected encapsulation efficiency, with ft demonstrating the highest encapsulation efficiency across all compounds, ranging from 0.41 to 9.86% for individual compounds, and 21.8 to 45.99% for mixed compounds, in comparison to other treated starches.
