Effect of Adding Thymus leptobotrys on Extra Virgin Olive Oil’s Quality and Physicochemical Parameters
نویسندگان
چکیده
The present study aimed to evaluate the changes in extra virgin olive oil (EVOO) after enrichment treatments with Thymus leptobotrys, a Moroccan endemic aromatic plant. EVOO sample was supplemented two materials obtained from aerial parts of T. leptobotrys: powder (2.5 and 5%) or essential (100 200 ppm). chemical composition analysis leptobotrys extracts (essential methanolic extract) allowed determination its phenolic profile. Quality parameters (acidity, peroxide value, specific extinction coefficients), color, fatty acids composition, minor components (pigments phenol), Rancimat oxidative stability control enriched oils were measured. Rosmarinic acid thymusin main identified compounds powder; for first time where it predominant. Generally, enrichments did not downgrade initial category (EVOO), according quality indexes. Adding EVOO, especially oil, profile by allowing migration thymusin, lipophile flavone, without affecting color.

Factors that influence color degradation in extra virgin olive oils
In the last twenty years the consumption of olive oil has gone from being located in the Mediterranean Area to expanding around the world and considering today the olive oil as a product of global consumption . Doubtless, one of the pillars that has allowed the rapid expansion of its consumption is its rich composition in polyphenols, sterols and antioxidants that confer numerous benefits for h...
متن کاملComparative analysis of quality parameters of Italian extra virgin olive oils according to their region of origin
Italian extra virgin olive oils from four regions covering different latitudes of the country were considered. They were analyzed by means of absorption spectroscopy in the wide 200-2800 nm spectral range, and multivariate data processing was applied. These spectra were virtually a signature identification from which to extract information on the region of origin and on the most important quali...

Effect of Fatty Acid Composition on Thermal Stability of Extra Virgin Olive Oil
Background: Fatty acids are the main compounds in edible oils. Oil thermal stability depends on the composition of fatty acids. So, this study was conducted to investigate the effect of fatty acid composition on the oxidative stability of extra virgin olive oil during heating process. Methods: Totally, eight virgin olive oil samples, including five imported oils from market place of Ma...
