Abstract:
This paper discusses about the optimization of process parameters for the microwave assisted extraction (MAE) of anthocyanin from Hibiscus rosa-sinensis using ethanol and water as solvent. The experimental design was formulated with the help of response surface methodology (RSM). The process parameters viz. microwave power, exposure time and solvent to sample ratio were optimized based on the yield of anthocynine content. The maximum yield of anthocyanin was obtained with the treatment combination of 400 W microwave powers, 180 s extraction time, 25 (v/w) solvent to sample ratio in water as a solvent, whereas with ethanol as a solvent a microwave power of 400 W, exposure time of 120 s with 25 (v/w) solvent to sample ratio reported highest anthocynine yield. Microwave assisted extraction of anthocyanin using acidified ethanol gave higher anthocyanin content (maximum 179.75 mgL-1) compared to MAE assisted extraction of water (101.356 mgL-1).
