Feed supplemented with byproducts from olive oil mill wastewater processing increases antioxidant capacity in broiler chickens
Gerasopoulos, K.; Stagos, D.; Kokkas, S.; Petrotos, K.; Kantas, D.; Goulas, P.; Kouretas, D. (2015)In the present study, a ceramic membrane microfiltration method was used for the separation of two liquid products, the downstream permeate and the upstream retentate, from olive mill wastewater (OMWW). These liquid products ... -
Grape pomace extract exerts antioxidant effects through an increase in GCS levels and GST activity in muscle and endothelial cells
