Fluorescence of Vegetable Oils: Olive Oils
Journal of Agricultural and Food Chemistry, 2005Fluorescence spectra of undiluted extra virgin olive oil obtained with the traditional setup (right-angle fluorescence) show considerable artifacts and deformations due to self-absorption phenomena, even when the spectra are corrected for inner filter effects. On the other side, front-face fluorescence spectra are much less affected by self-absorption.

Abstract Serial intracutaneous injections of chemically pure, synthetic glyceryl trioleate (triolein) lead to the same allergic reactions as vegetable oils. The sensitization by natural vegetable oils can be attributed to fatty acid triglycerides and not to impurities. This sensitization is not accompanied by a rise of the blood eosinophils.

Vegetable oils under a protected designation of origin (PDO) are highly susceptible to fraud. Therefore, in order to protect the producers, inform the consumers and contribute to the maintenance of a high quality within the sector, huge efforts have been made to discover analytical strategies to verify the authenticity of PDO vegetable oils. Due to its

Conventional vegetable oil mills are complex plants, processing oil, fruits, or seeds to vegetable fats and oils of high quality and predefined properties. Nearly all by-products are used. However, most of the high valuable plant substances occurring in oil fruits or seeds besides the oil are used only in low price applications (proteins as animal ...

Lactones in autoxidized vegetable oils
Journal of the American Oil Chemists' Society, 1967AbstractIt was demonstrated that bothgamma anddelta saturated lactones are present in highly peroxidized vegetable oils. In the oils which were investigated thegamma isomers are predominant. Additional lactones also form when the hydroperoxides are reduced.

Allergenicity of refined vegetable oils
Food and Chemical Toxicology, 2000Several commercially important refined vegetable oils are derived from plants which are recognized as potent food allergens (e.g. peanut, soy). Full refining of oils results in the almost complete removal from oils of protein, which is responsible for allergic reactions.
