The present invention relates to fuel derived from renewable resources. More specifically, the present invention provides a composition which can be used as a fuel and a mixture which can be added to one or more C.sub.8-22 fatty acid triglycerides in order to provide a fuel. In particular, the present invention concerns the reduction of decomposition of such fuels due to bacterial growth and oxidation.

Provided herein are microencapsulated compositions, optionally oil-in-water emulsions, comprising one or more long chain polyunsaturated fatty acids (LCPUFAs), optionally in triglyceride form, wherein the encapsulant comprises one or more low molecular weight proteins. In particular embodiments the composition has a surface free fat content of about 1%. Also provided are methods for protecting one or more LCPUFAs, or one or more oils comprising the one or more LCPUFAs, from oxidative degradation, comprising encapsulating the LCPUFAs or oil with an encapsulant comprising one or more low molecular weight proteins.

An object of the present invention is to provide an oil and fat composition with unprecedentedly strong oxidative stability by using a simple method. The invention has been completed with the findings that an oil and fat composition shows an extremely strong oxidation stabilizing effect, the antioxidant oil and fat composition comprising an aqueous phase containing a water-soluble antioxidant and a carbohydrate and having a certain degree or more of water-soluble solids content, the aqueous phase being dispersed in an oil phase, wherein the antioxidant oil and fat composition contains a certain amount of water.

The objective of the present invention is to provide compositions containing vegetable oils and an anti-oxidant system to prevent oxidation of the triglycerides in the vegetable oil in food products, in particular in products which are often stored for a long time. The antioxidant system should not give an undesired colour, and neither an undesired taste, to a food composition. Additionally, it should be a natural compound and/or common food ingredient, and fitting to the food composition with regard to taste and colour. This has been achieved by providing a food composition containing vegetable oil, wherein the composition comprises a source of organic acids, one or more organic acids other than acetic acid, amino acids, and one or more phenolic compounds. More in particular the source of organic acids comprises organic acids other than acetic acid to total organic acids in the source of organic acids at a weight ratio ranging from 0.5% to 60%; and the weight ratio of one or more amino acids to total organic acids in the source of organic acid ranges from 0.03% to 20%.

Suggested is a composition with stabilized taste and/or odor, comprising (a) at least one acetophenone derivative of formula (I) wherein R.sub.1 stands for hydrogen or methyl, and R.sub.2 stands for hydrogen, hydroxyl or a OCH.sub.3 group, or a cosmetically pharmaceutically acceptable salt thereof, and (b) at least one mono- or polyunsaturated C.sub.8-C.sub.22 fatty acid or its monohydric polyhydric C.sub.1-C.sub.18 alkyl alcohols ester.

The present invention is directed to seed oil compositions that can be used for cooking and frying applications. These oil compositions of the present invention have advantageous stability characteristics. In some embodiments, the oil compositions have a low concentration of -linolenic acid.

The present invention is directed to processes for preparing oil compositions having a high concentration of poly-unsaturated fatty acids and oil compositions having a low concentration of -linolenic acid. In addition, the present invention is directed to processes for preparing oil compositions having advantageous stability characteristics.

The present invention relates to a method for stabilizing fatty acids present in a sample such as bodily fluids. The present invention further relates to a solid medium which is capable of stabilizing fatty acids applied thereto, and a method for preparing same. The present invention further relates to a method for determining the fatty acid composition of a sample.

The present invention relates to stable oil-in-water emulsions comprising a polyunsaturated fatty acid, an emulsifier, water, a metal chelating agent, and an antioxidant, and processes for preparing the stable oil-in-water emulsions. The stable oil-in-water emulsions are substantially free from coalescence, flocculation, Ostwald ripening, and creaming, for a period of at least five months at a temperature of about 4 C.

In each of its various embodiments, the present invention discloses microemulsions that carry antioxidants.
