The oxidative stability of seven oils with different fatty acid profiles was assessed. Oxidation at 0, 2 and 4h at 180oC was monitored by measuring the absorbance of thiobarbituric acid reactive substances (TBARS) along the absorption spectrum (300600 nm), the volatile aldehydes (HS-SPME-GC-MS) and the fatty acid profile (FIDGC). TBARS absorption spectrum behavior depended on the lipid composit...

The influence of volatile fatty acids on the ecology of the bacterial flora of the mouse intestinal tract has been studied in three situations where large fluctuations in the composition of the microflora have been observed. Young mice were shown to ingest solid food particles when 11 days old; this correlated with the appearance of strictly anaerobic fusiform bacilli in the intestinal lumen an...

Analytical methods are required in addition to administrative controls to verify the geographical origin of vegetable oils such as palm oil in an objective manner. In this study the application of fatty acid and volatile organic compound fingerprinting in combination with chemometrics have been applied to verify the geographical origin of crude palm oil (continental scale). For this purpose 94 ...

effects of summer savory (satureja hortensis l.) dry powder (ssdp) and essential oil (sseo) on performance, ruminal fermentation and blood metabolites were assessed using 20west azerbaijan native kids (16±1.94 kg initial live weight) in a random block design with 5 treatments (4 replicates per treatment) over a 13-week period. treatments were: i) basal diet without additive (control), ii): basa...

Data in this article presents fatty acid composition of three mango cultivars; Alphonso, Pairi and Kent through fruit development and ripening. Change in the ω-6 and ω-3 fatty acids level during mango fruit development and ripening is depicted. Also, data on aroma volatile 'lactones' composition from pulp and skin tissues of these cultivars at their ripe stage, respectively is provided. Statist...

the objective of this study was to investigate the effects of summer savory essential oil (sseo) with cereals (based on barley or corn) on performance, rumen volatile fatty acid concentrations and some blood parameters of west azerbaijan native kids. in a randomized complete block design with a 3×2 factorial (0, 200 and 400 mg/d of sseo × barley or corn grain based diets) arrangement with 6 rep...

background: the high percentage of consumed antibiotics by humans and animals is excreted with other residues from the body after its performance. by entering these compounds to the wastewater, they can disrupt the anaerobic treatment process. in this study, deterrent behavior of two ampicillin and gentamicin antibiotics are investigated on specific methanogenic activity (sma) of anaerobic biom...

This study aims at to elucidate the nature and chemical component of rancid flavor of oils which are differently oxidized and also to discuss the effect on such rancidities by the different fatty acid composition of oils and by the different extent of the oxidation. The flavors of rancid soybean, corn and olive oil were evaluated by the organoleptic method and the natures of their flavors were ...
