摘要：
An integrated process for collective recovery of phenolic compounds from olive mill wastewater (OMW) and grape pomace (GP), which would also benefit easier biodegradation of OMW in a further process, was developed. Response surface methodology was employed to optimize the process parameters. Treatment of GP with OMW resulted in the transfer of 64.41 % of total polyphenols contained in OMW to GP under the optimal conditions predicted by the model. In the following step, extraction of phenolic compounds in treated-GP with ethyl alcohol:water under the optimum conditions predicted by the model was performed and 11.97 mg g(-1) phenolics was recovered. The total antioxidant activity of the recovered phenolics was 81 % (inh.).
