Influence of the deep fat frying process on the lipid profile of the fat contained in the “french” type fried potato using palm olein

Grasas y Aceites, 2010
The aim of this investigation was to evaluate the influence of certain variables of the process of deep fat frying on the lipid profile of the fat fraction of the potato type “french” (Solanum tuberosum) using palm oil. This marked the first fat fraction

An agenda for the future of Arctic snow research: the view from Svalbard [PDF]

, 2023
The Arctic region is warming at over twice the mean rate of the Northern Hemisphere and nearly four times faster than the globe since 1979. The local rate of warming is even higher in the European archipelago of Svalbard. This warming is transforming the

Evaluation of Retention Mechanisms of Polar Compounds on Polar Stationary Phases Based on Type C Silica

Separations
Polar compounds can be separated on polar stationary phases attached on the surface of silica hydride (Type C silica). Although aqueous normal phase (ANP) chromatography has been used to denote this mode of separation, there have been no detailed studies

Apparent and quantitative loss of fatty acids and triacylglycerols at frying temperatures

Grasas y Aceites, 2012
Olive and sunflower oils were heated at 180 °C for 5, 10 and 15 hours with the aim of defining the changes in the contents of fatty acid methyl esters (FAME) and triacylglycerols (TAG) under frying conditions.
