Anthocyanin Content and Color Stability in Black Rice According to Different Extract Conditions and Selected Stabilizers

TLDR: In this article, the authors analyzed the anthocyanin content of black rice crude extract according to different extraction methods, as well as to compare the effects of stabilizers (cyclodextrin, maltodeextrin) and sugars (sucrose, maltose) on color deterioration.

Abstract: The purpose of this study was to analyze the anthocyanin content of black rice crude extract according to different extraction methods, as well as to compare the effects of stabilizers(-cyclodextrin, maltodextrin) and sugars(sucrose, maltose) on anthocyanin color deterioration, which was examined at for min. In the water extract, C3G (cyanidin-3-glucoside) was detected, 3.22 ppm and 3.29 ppm of C3G respectively. In the water extract, anthocyanin color deterioration was retarded by 10% sucrose and 1% maltose and the thermal color deterioration was retarded by the additions of 1% maltodextrin and 1% -cyclodextrin.
