A gas chromatography (GC) method including a full evaporation headspace (FE-HS) sampling technique was developed for rapidly and simultaneously measuring volatile products for acetone-butanol-ethanol (ABE) fermentation. In this method, a small volume (<50 μL) of fermentation broth was directly injected into a sealed headspace sample vial (22 mL) and the mass transfer of acetone-butanol-ethanol ...
The parameters affecting the separation and quantification of trimethylsilyl ethers of mono- and diglycerides have been investigated by gas-liquid chromatography with QF-1 and SE-30 as stationary phases and a flame ionization detector. Results have been compared with those obtained earlier for triglycerides. The isothermal characteristics of a range of trimethylsilyl ethers of mono- and diglyce...
Given that fermented dairy products exhibit high bioactivities against cardiovascular diseases (CVDs), the anti-thrombotic properties, fatty acid profiles and sensory properties of cow, goat and ewe derived Greek yogurts have been assessed and compared. The total lipids (TL), total polar lipids (TPL), total neutral lipids (TNL) were obtained and the polar lipid fractions were further separated ...
