Abstract: In order to optimize the microwave-assisted extraction process for anthocyanins from bilberry using 1% HCl ethanol as the solvent, response surface methodology was used to explore the effects of microwave power, microwave treatment time, solvent concentration and extraction temperature on extraction rate of anthocyanins on the basis of single-factor investigations. Results indicated that the optimal extraction conditions for anthocyanins from bilberry was microwave powder of 500 W, microwave treatment time of 7 min, solvent concentration of 55%, and extraction temperature of 51 ℃. Under the optimal extraction conditions, their extraction efficienc of anthocyanins from bilberry was (1.47 ± 0.15) mg/g.

Key words: bilberry, anthocyanins, extraction processing, response surface methodology (RSM)
