Biodiesel production using waste frying oil
Waste Management, 2011Waste sunflower frying oil is used in biodiesel production by transesterification using an enzyme as a catalyst in a batch reactor. Various microbial lipases have been used in transesterification reaction to select an optimum lipase. The effects of various parameters such as temperature, methanol:oil ratio, enzyme concentration and solvent on the ...

AbstractThe rapid development of China's economy has resulted in a dramatic increase in the production and purchase of instant fried food products by consumers. China's food industry has relied largely on the importation of soybean oil and palm oil. Palm oil is widely used by the commercial food industry because of its high oxidative stability and low ...

Volatile Constituents of Used Frying Oils
Journal of Agricultural and Food Chemistry, 1996The 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 ...

Membrane processing of used frying oils
Journal of the American Oil Chemists' Society, 2000AbstractStudies 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.

Use of silicones in frying oils
Journal of the American Oil Chemists' Society, 1973AbstractSilicones (polydimethyl siloxanes) greatly increase the oxidative stability of an edible oil at high temperature. The effect is demonstrated here, using a thin layer chromatography technique to follow the oxidation of the oil. The minimum fully effective concentration corresponds to a monolayer of silicone on the air‐to‐oil surface.

Critical Reviews in Food Science and Nutrition, 2021
Deep-fried meat products are widely popular. However, harmful compounds produced by various chemical reactions during frying have been shown to be detrimental to human health. It is of great necessity to raise practical suggestions for improving the oxidation problem of frying oils and frying conditions in some aspects.

Regeneration of used frying oils using adsorption processing
Journal of the American Oil Chemists' Society, 2003AbstractOur 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.

Feasibility of recycling used frying oil using membrane process
European Journal of Lipid Science and Technology, 2001A study was carried out to improve the quality of used frying oils and to assess the feasibility of recycling using a membrane process. Experiments were conducted with used frying oils in a flat membrane batch cell using polymeric membranes. The total polar materials and oxidation products, which normally lead to the deterioration of frying oils, were ...

Standard methyl esters from used frying oils
Fuel, 2013Abstract 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.

The use and abuse of frying oil
Food Service Technology, 2001AbstractThe quality of frying oil discarded by a sample of catering establishments was assessed using a rapid test method, which measures the free fatty acid (FFA) concentration. Results show that none of the establishments used an objective assessment method; a lack of consistency between establishments, and many discarding oil where the FFA levels ...
