Abstract

This research aimed to evaluate the influence of the modified starch with octenyl succinic anhydride (MS) on anthocyanins content and the physical properties of the jaboticaba peel freeze-dried powders. The formulations were obtained by mixtures of jaboticaba peel pulp and different MS content (10%, 15%, 20%, and 25%, w/w). The powders were characterized by physical properties, differential scanning calorimetry (DSC), infrared spectroscopy using the Fourier transform (FTIR), and anthocyanins content and retention by HPLC-DAD. DSC analysis showed an increase in the glass transition temperature of the powders with an increase in the MS content (from -10.26 degrees C to 53.40 degrees C). Three anthocyanins were identified and quantified: delphinidin-3-O-glucoside, cyanidin-3-O-glucoside (main anthocyanin present in the samples), and peonidin-3-O-glucoside. The retention of anthocyanins increased significantly with increasing MS content (from 18.0% to 58.0%). Overall, a positive effect of the MS content in the physical and physical-chemical characteristics of jaboticaba peel pulp powders could be observed. (AU)
