Abstract
Black glutinous rice (BGR) was milled and the bran was collected for anthocyanins extraction. The broken rice fraction was enzymatically produced as black glutinous rice maltodextrins (BRM) with 3 dextrose equivalents (DE), including DE10 (BRM10), 20 (BRM20) and 30 (BRM30). The BRMs were used as wall materials in microencapsulation processes. Feed mixtures were spray dried at 3 inlet air temperatures (140, 160 and 180 °C) and freeze dried at −45 °C. Process yield, anthocyanin retention, and powder properties were investigated. The results demonstrated that increasing the inlet air temperature caused a decrease in the bulk density and anthocyanin retention. Moreover, increasing the inlet air temperature enhanced dehydration, process yield, solubility, dispersibility, flowability and smooth particle surface
