Modelling of the microencapsulation of betacyanins and their antioxidant activity extracted from red amaranth

Betacyanin is a type of betalain responsible for red or violet color and can be found in the family Amaranthus gangeticus. This water-soluble natural pigment can be extracted using water extraction and spray drying was involved to produce pigment powder. The objective of the study is to optimize and...
