Infrared spectroscopy for quantitative analysis and oil parameters of olive oil and virgin coconut oil: A review

Virgin coconut oil improves hepatic lipid metabolism in rats--compared with copra oil, olive oil and sunflower oil.

Effect of virgin coconut oil (VCO) on lipid levels and regulation of lipid metabolism compared with copra oil (CO), olive oil (OO), and sunflower oil (SFO) has been reported. Male Sprague-Dawley rats were fed different oils at 8% level for 45 days along with synthetic diet. Results showed that VCO feeding significantly lowered (P < 0.05) levels of total cholesterol, LDL+ VLDL cholesterol, Apo B...

Virgin olive oil and nutrition

Numerous medical studies (a study in seven countries, Monika study, Dart studies, etc. ) have shown that olive oil is one of the most important ingredient of "Mediterranean diet" associated with a reduction in cardiovascular disease and certain types of cancerous diseases. Nutritional and health value of virgin olive oil is attributed to the large proportion of monounsaturated fatty acids (main...

Sensory Analysis of Virgin Olive Oil

Detection of extra virgin olive oil adulteration with lampante olive oil and refined olive oil using nuclear magnetic resonance spectroscopy and multivariate statistical analysis.

High-field 31P NMR (202.2 MHz) spectroscopy was applied to the analysis of 59 samples from three grades of olive oils, 34 extra virgin olive oils from various regions of Greece, and from different olive varieties, namely, 13 samples of refined olive oils and 12 samples of lampante olive oils. Classification of the three grades of olive oils was achieved by two multivariate statistical methods a...

Quantitative Analysis of Peroxide Value in Virgin Coconut Oil by ATR- FTIR Spectroscopy

Oxidation of fats and oils is an important indicator for performance and shelf life of oils. As other vegetable oils, virgin coconut oil (VCO) is not susceptible to lipid oxidation. Thus, a rapid method for quantitative analysis of peroxide value in VCO was developed in this study using Fourier transform infrared (FTIR) spectroscopy coupled with attenuated total reflectance (ATR). Thirty traini...
