Özet

The influence of microwave-assisted extraction (MAE) on the recovery of phenolic compounds from blueberry was investigated. Response surface methodology (RSM) was applied to optimize the extraction conditions. Microwave power, extraction time and solvent to sample ratio were selected as extraction parameters. Ranges of independent variables were 100-300 W of microwave power, 2-16 min of extraction time and 5:1-50:1 ml/g of solvent to sample ratio. Responses of model were extraction yield and total phenolic content (TPC) and total anthocyanin content (TAC) for extraction of blueberry powder. Optimum conditions of MAE based on maximum levels of responses were 287 W of microwave power, 13 min of extraction time, 40:1 ml/g of solvent to sample ratio. Maximum levels of responses under optimum conditions obtained were an extraction yield of 78.35%, TPC of 30.75 mg GAE/g blueberry powder and TAC of 8.92 mg Cyn-3-glu/g blueberry powder.
