Two steps methanolysis and ethanolysis of olive pomace oil using olive-pomace-based heterogeneous acid catalyst

Fuel, 2021
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,

Polycyclic Aromatic Hydrocarbons and Olive Pomace Oil

Journal of Agricultural and Food Chemistry, 2004
The 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

Phthalates levels in olive oils and olive pomace oils marketed in Turkey

Food Additives & Contaminants: Part A, 2020
Phthalates are used as additives and plasticisers in packaging for personal care and food products. Several investigations reported the harmful impact of phthalates on human health. In this study, different types of olive oils (12 olive oil; 20 extra virgin oil; 4 refined pomace oil) in different packaging materials [polyethylene terephthalate (PET ...

Possibility of improving the quality characteristics of olive‐pomace oil and enhancing its differentiation from refined olive‐pomace oil

Journal of the Science of Food and Agriculture, 2000
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

Reducing polycyclic aromatic hydrocarbons (PAHs) formation in olive pomace oil using microwave pre‐heating of olive pomace

European Journal of Lipid Science and Technology, 2016
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.

Evaluation of the State of Oxidation of Crude Olive-Pomace Oils. Influence of Olive-Pomace Drying and Oil Extraction with Solvent

Journal of Agricultural and Food Chemistry, 1997
The aim of this investigation was to follow the progress of oxidation during the phases of the industrial process of olive-pomace drying and the subsequent step of crude pomace oil extraction with solvent. Silica-gel column chromatography and high-performance size-exclusion chromatography were the analytical techniques utilized to this purpose.
