Polycyclic Aromatic Hydrocarbons and Olive Pomace Oil
Journal of Agricultural and Food Chemistry, 2004The occurrence of polycyclic aromatic hydrocarbons (PAHs) in five samples of olive pomace oil has been studied to determine the contamination degree of this type of oil and to evaluate if specific purification steps must be introduced during its manufacture. The PAHs present have been determined by gas chromatography-mass spectrometry. A high number of

Abstract Olive pomace (OP) and olive pomace oil (OPO) are low-cost, non-edible, by-products of olive oil processing. Converting OPO into biodiesel by (trans-)esterification and olive pomace into a heterogeneous acid catalyst by sulfonation with sulfuric acid could promote waste-to-energy actions. OPO has a high fatty acid content of 126.39 mgKOH/goil,

Carbon Stable Isotopes and Olive Oil Adulteration with Pomace Oil
Journal of Agricultural and Food Chemistry, 1997Adulteration of olive oils can be detected by comparison of the 13C/12C ratios as obtained subsequently by high-resolution gas chromatography (HRGC) and isotope ratio mass spectrometry (IRMS). In δ13C values determined for the aliphatic alcoholic fraction of pomace oil, the adulterant was significantly more negative than those of virgin and refined ...

Mixed-culture polyhydroxyalkanoate production from olive oil mill pomace
Bioresource Technology, 2012Polyhydroxyalkanoate (PHA) was produced in bench-scale sequencing batch reactors (SBRs) fed olive pomace fermentate containing a mixed microbial consortium. Initial anaerobic fermentation in a sequencing batch fermentor (SBF) produced soluble carbon compounds, mainly organic acids. SBF effluent was centrifuged, removing solids, and fed into a SBR where

Stability of refined olive oil and olive‐pomace oil added by phenolic compounds from olive leaves
European Journal of Lipid Science and Technology, 2010AbstractRefined olive oil and olive‐pomace oil were enriched with olive leaf phenolic compounds in order to enhance its quality and bring it closer to virgin olive oil. The changes that occurred in the concentrations of pure oleuropein, oleuropein aglycone, hydroxytyrosol acetyl and α‐tocopherol at 400 µg/kg of oil during the storage of refined olive ...

Biodiesel production from pomace oil by using lipase immobilized onto olive pomace
Bioresource Technology, 2011In the present work, microbial lipase from Thermomyces lanuginosus was immobilized by covalent binding onto olive pomace. Immobilized support material used to produce biodiesel with pomace oil and methanol. The properties of the support and immobilized derivative were evaluated by scanning electron microscopy (SEM).

An investigation was carried out to evaluate the oxidative and hydrolytic degradation of 37 olive-pomace oils marketed in southern Italy and to compare the results with those obtained from 10 deodorised olive-pomace oils representative of large stocks of oil obtained after the final step of refining. One aim of the research was to ascertain the quality

High temperature application during drying of olive pomace before solvent extraction leads to formation of polycyclic aromatic hydrocarbons (PAHs) and their eventual presence in the oil. Therefore, the objective of this study was to investigate a mitigation possibility of PAHs in olive pomace oil.
