Abstract This research examines the effect of adding olive leaf on the yield and quality of the olive oil extracted from malaxation and ultrasound application during the olive oil extraction process. The olive variety Ayvalık was used in the trials, which included leaf addition of 2% and 5% and ultrasound application of 5, 10, 15, 20, 25, 30, 35, and 40 minutes (min). Several values, such as maturity index and oil yield, as well as olive oil parameters, including free acidity, peroxide value, oxidative stability, and specific ultraviolet absorption, were analyzed and examined. We also carried out sensory analyses on the extracted olive oils. The results show that the product extracted has no sensory defects and exhibits a fruitiness level greater than 0.... |

ABSTRACT The objective of the study was to examine the effects of an alcoholic liquid olive leaf extract (OLE) obtained from fresh leaves on the growth performance, carcass weight, caecal microflora, and some plasma variables, such as triglycerides, total cholesterol, high-density lipoprotein (HDL), and low-density lipoprotein (LDL) cholesterol in broiler chickens. A total of 375 one-day-old male broilers (Ross 308) were randomly divided into five treatments with five replicate pens (15 birds each) per treatment. The birds were fed either a basal diet with no supplement (control), with 75 (OLE75), 150 (OLE150), 300 (OLE300), and 600 (OLE600) mg kg−1 oleuropein, provided by 0.66, 1.33, 2.65, and 5.32 g kg−1 of the OLE. The dietary supplementation of OLE... |
