Standard methyl esters from used frying oils

Fuel, 2013
Abstract Used frying oils (UFO) are an interesting and important source material for manufacturing of methyl esters (ME) as alternative fuels. The technology of methyl ester preparation from UFO (abbreviated as UFOME) is similar as in the case of fresh oils.

Quality and safety of frying oils used in restaurants

Food Research International, 2014
Fresh, in-use and discarded frying oils were collected from randomly selected restaurants in downtown Toronto, Canada, in order to assess the oxidative and hydrolytic state of oil used in commercial practice and consumed regularly by the local population. All in-use and discarded samples showed extremely high levels of oxidation products based on the p-

Membrane processing of used frying oils

Journal of the American Oil Chemists' Society, 2000
AbstractStudies were conducted with used frying oils in a flat membrane batch cell using five different types of polymeric membranes to decrease the soluble degradation products. During membrane processing, triglycerides permeated preferentially compared to the majority of the polar compounds including oxidation products, polymers, and color compounds.

Volatile Constituents of Used Frying Oils

Journal of Agricultural and Food Chemistry, 1996
The volatile constituents of used frying oils obtained from a local food-processing plant were isolated by simultaneous distillation−extraction and fractionated by silica gel column chromatography. The isolates were analyzed by capillary gas chromatography and combined capillary gas chromatography−mass spectrometry, resulting in the identification of ...

Regeneration of used frying oils using adsorption processing

Journal of the American Oil Chemists' Society, 2003
AbstractOur study was carried out to improve the quality of used frying oils and to assess the feasibility of recycling by using an adsorption process. Experiments with used frying oils were conducted with a column method using four adsorbents, silica gel, magnesium oxide, activated clay, and aluminum hydroxide gel.

Survey of quality of used frying oils from restaurants

Journal of the American Oil Chemists' Society, 1991
AbstractCommercial frying practices and frying conditions at 62 restaurants or fast‐food outlets were investigated and the quality of their discarded frying oils was evaluated by several standard laboratory methods: total polar components (TPC), free fatty acids (%FFA), p‐anisidine and peroxide values, color, viscosity, C18:2/C16:0, absorbance at 232 ...
