Lipopolysaccharide (LPS) induces host inflammatory responses and tissue injury and has been implicated in the pathogenesis of various age-related diseases such as acute respiratory distress syndrome, vascular diseases, and periodontal disease. Antioxidants, particularly vitamin E, have been shown to suppress oxidative stress induced by LPS, but the previous studies with different vitamin E isof...

Olive oil contains a vast range of substances such as monounsaturated free fatty acids (e.g., oleic acid), hydrocarbon squalene, tocopherols, aroma components, and phenolic compounds. Higher consumption of olive oil is considered the hallmark of the traditional Mediterranean diet, which has been associated with low incidence and prevalence of cancer, including colorectal cancer. The anticancer ...

Rapeseed contains high amounts of phenolic compounds, mainly derivatives of sinapic acid, but only a small part can be found in virgin rapeseed oil, since the polar compounds remain in the press cake. A temperature treatment of the raw material results in the degradation of sinapic acid to 2,6dimethoxy-4-vinylphenol (vinylsyringol or canolol), which is described in literature as a very strong a...

Wheat germ represents approximately 3% of the grain and it contains 8-14% oil, which is a rich source of tocopherols (vitamin E) and polyunsaturated fatty acids, mainly linoleic acid. The present work shows the influence of temperature (27oC and 45oC) and storage time (maximum 35 days) of the wheat germ on the concentration of tocopherol in the oil. Their effect on other quality parameters was ...

BACKGROUND The use of traditional foods can enrich our diet, perpetuating important elements of local knowledge and cultural inheritance. Raw, soaked and cooked samples of two Fabaceae species (Cicer arietinum L. and Lathyrus sativus L.) were characterized regarding nutritional and bioactive properties. RESULTS L. sativus gave the highest carbohydrate, protein, ash, saturated fatty acid and p...

A two-year survey in 18 representative groves of a north Italian olive district sampled cvs. ‘Casaliva’ and ‘Leccino’ for single-site oils. Polyphenols had a major role in determining oil autoxidation stability with respect to tocopherols, even if the higher autoxidation stability of ‘Leccino’ over ‘Casaliva’ was probably due to the more than double content in tocopherols, which was significant...

approximately 10-30% of tomatoes are wasted during processing. tomato pomace consists of crushed skin and seeds of tomatoes. seeds might be considered as a potential source of vegetable oil. the extracted oil is high in unsaturated fatty acids, namely linoleic acid. the extracted oil after purification or refining might be employed for consumption. the object of this study was to evaluate the e...

Carotenoids and tocopherols are lipophilic antioxidants with important functions in plants and humans. Due to their nutritional value and putative health benefits, they have become a focus of intensive research. The identification of all genes of the carotenoid and tocopherol biosynthesis has enabled the manipulation of their biosynthetic pathways, aiming for quantitative and qualitative improv...
