The use of agro-industrial co-products in animal nutrition could represent an opportunity to reduce the environmental impact food production chain. Co-products can decrease feeding cost and improve products terms quality sustainability. To evaluate as feed, 57 studies published last 11 years on residues were considered. In vitro trials demonstrated that some co-products, such ginseng meal, grap...

Extremely high removals of total suspended solids and oil and grease were obtained when olive mill wastewaters were filtered using new silicon carbide tubular membranes. These new membranes were used at constant permeate flux to treat real olive mill wastewaters at pilot scale. The filtration conditions were evaluated and optimized in terms of the selection of the permeate flux and flux mainten...

The objective of this study was to investigate the effects of partial replacement of wheat hay with sun-dried (SOC) or acid-treated SOC (ASOC) olive cake on nutrient intake and performance of Awassi lambs. An additional objective was to study the effects of acid treatment of olive cake (OC) on its chemical composition and nutritive value. On DM basis, sun-drying of OC did not dramatically affec...

The surface-active and emulsifying properties of crude aqueous ethanolic extracts from untreated olive oil cake (OOC) were investigated. OOC contained important concentrations components including proteins, saponins polyphenols (1.2–2.8%, 7.8–9.5% 0.7–4.5% (w/w), respectively) reduced the interfacial tension by up to 46% (14.0 ± 0.2 mN m?1) at oil–water interface. ability was not correlated, ho...

Olive waste cake (OWC) is underestimated as an agricultural waste. In this work, OWC extract were obtained by ethanol. Antioxidant efficacy of ethanolic OWC extract at levels of 100, 200, 400 and 600 ppm were studied. Samples of sunflower oil mixed with OWC extract were intermittent heated at 180±5°C for 4 hr / day, for 5 consecutive days and has been assayed for stabilization of sunflower oil ...
