Olive scale (Parlatoria oleae (Colvée)) is a common pest in Mediterranean olive orchards which primarily causes damage on olive fruits. The quality of virgin olive oil is strongly related to the health status of the olive fruits from which is extracted. In this paper the effects of olive scale (Parlatoria oleae (Colvée)) attack on the oil yield, chemical and sensorial quality, as well as on the...

The mixture of olive oil and lime cream has been traditionally used to treat external burns in the region of Hatay/Antakya and middle Anatolia. Olive oil and lime cream have been employed by many physicians to treat many ailments in the past. A limited number of studies have shown the antibacterial effect of olive oil and that it does not have any toxic effect on the skin. But we did not find a...

Apulia (Southern Italy) is the leading Italian region for the production of olive oil (115 × 106 kg of oil/year), and the olive oil chain is really important from a business point of view. Currently, the extraction of olive oil is essentially performed by using a mechanical pressing process (traditional olive oil mills), or by the centrifugation process (modern olive oil mills). The aim of this...

Abstract In this work, pilot-scale nanofiltration was used to obtain aqueous solutions rich in hydroxytyrosol and tyrosol from olive oil by-products. A large-scale simple process involving mill standard machinery (blender decanter) for the pomace pre-treatment with water. The extract then directly fed a unit concentrated by reverse osmosis. Final concentration factors ranged between 7 9 4 tyros...

An instrumental method for the evaluation of olive oil quality was developed. Twenty-one relevant aroma active compounds were quantified in 95 olive oil samples of different quality by headspace solid phase microextraction (HS-SPME) and dynamic headspace coupled to GC-MS. On the basis of these stable isotope dilution assay results, statistical evaluation by partial least-squares discriminant an...

Platelet activating factor (PAF), a potent inflammatory mediator, is implicated in several proinflammatory/inflammatory diseases such as glomerulonephritis, glomerulosclerosis, atherosclerosis, cancer, allergy, and diabetes. PAF can be produced by several renal cells under appropriate stimuli and it is thought to be implicated in renal diseases. The aim of this study is the characterization of ...

Enzymatic lipophilization has been proposed as a cost-effective strategy to produce new liposoluble antioxidant compounds. In this study, modified oils rich in structured phenolipids were prepared via one-pot enzymatic acylation of hydroxytyrosol (HTYR), vanillyl alcohol (VA) and homovanillyl (HVA) with pomace olive oil (POO) solvent-free conditions using immobilized lipase on biogenic nanopart...
