The etiologic agent(s) that was responsible for the 1981 toxic oil syndrome [TOS] epidemic in Spain has not been identified. Liquid chromatography combined with atmospheric pressure ionization tandem mass spectrometry was used for the analysis of oils associated with TOS. Analyses focused on measuring 3-(N-phenylamino)-1,2-propanediol [PAP], the 3-oleyl ester of PAP [MEPAP], and the 1,2-di-oley...

Improved conditions for gas-liquid chromatography of triglycerides are reported. Triglycerides of bovine colostrum and rapeseed oil have been analyzed under these conditions.

The aim of the study was an evaluation of the influence of chicken feed supplementation with plant oils contain high amount of polyunsaturated fatty acids on histochemical characteristics of meat. Chickens Vedetta were divided into three experimental groups and they were fed with feed DKA-SFA; control group and with the addition of rapeseed oil of 2.75% and vitamin E 0.015%, as well as of 8.25%...

Canola is an offspring of rapeseed (Brassica napus and Brassica campestris/rapa), which was bred through standard plant breeding techniques to have low levels of erucic acid and glucosinolates. Canola seed is rich in oil, and after oil extraction, the remaining “canola meal” (CM), is a rich protein source used as feedstock to different animal species, mainly dairy cows in North America and in E...

Many samples of rapeseed oil ethyl ester were prepared by alkaline-catalyzed transesterification at various conditions (reaction time, temperature, amount of catalyst, the molar ratio of ethanol to oil, the rotations of a disperser and the purification by water). The concentrations of the key impurities for biodiesel quality (the concentrations of monoglycerides, diglycerides, triglycerides, fr...

AOCS Official Method Ce 6-86 "Antioxidants, Liquid Chromatographic Method" was originally developed to confirm the correct antioxidant was added at the specified concentration to refined oils. Today, this method is increasingly utilized to validate that antioxidants are absent from oil products. False positive results can have a significant impact on the ability to sell products in specific mar...

Lysophosphatidic acid acyltransferase acylates the sn-2 hydroxyl group of lysophosphatidic acid to form phosphatidic acid, a precursor to triacylglycerol. A cDNA encoding lysophosphatidic acid acyltransferase was isolated from developing seeds of meadowfoam (Limnanthes alba alba). The cDNA encodes a 281-amino acid protein with a molecular mass of 32 kD. The cDNA was expressed in developing seed...

Biodiesel or fatty acids alkyl esters (FAAE) of long chain are an alternative fuel produced by a transesterification process. The potential production of biodiesel from rapeseed oil in Chile is associated to the solution of economic, environmental and social problems. Experiences from other countries have demonstrated that biodiesel prices are higher than diesel, due to the high costs of the ra...

In this study, the preparations of biodiesel from three different feedstocks, including rapeseed oil, high acidified Chinese wood oil and trap grease, were carried out in a pilot scale of 200 t yr-1 biodiesel production system. The optimum operating conditions for transesterification of rapeseed oil in plug flow reactor were found to be as follows: the catalyst dosage is 1.2 wt%; the retention ...
