Mineral oil hydrocarbons (MOH), including saturated (MOSH) and aromatic (MOAH) hydrocarbons, are contaminants of petrogenic origin. On-line high-performance liquid chromatography (HPLC) - gas chromatography (GC) - flame ionization detector (FID) was used for determining MOH in olive oils (OOs) and olive pomace oils (OPOs) at different stages of the ...

Bleaching of olive pomace oil with Spirulina platensis as an eco-friendly process
Algal Research, 2021This study is the first attempt for bleaching of olive pomace oil by Spirulina platensis biomass as a function of contact time (0–180 min), initial pH (2, 3, 4, and 5), biomass value (2, 4, 8, and 12 g/L), and temperature (303, 323, and 343 K) in a batch

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

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.

Following the olive oil production chain: 1D and 2D NMR study of olive paste, pomace, and oil
European Journal of Lipid Science and Technology, 2014 Extraction methods are critical in the production and success of an extra virgin olive oil ready for consumption. The first step of olive oil extraction procedure produces an olive paste, which is subsequently processed by separation of the liquid phases

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

Change in glyceride composition of olive pomace oil during enzymatic esterification
Food / Nahrung, 2004AbstractEnzymatic esterification of free fatty acids of olive pomace oil with glycerol was investigated. The esterification reaction was carried out in the absence and presence of glycerol (glycerol to free fatty acids (FFA) molar ratio of 1/3 and 1/6).
