Method for detecting the presence of an analyte in a sample
InactiveUS7097983B2High purityEliminate needBioreactor/fermenter combinationsFatty acid hydrogenationAnalyteBinding site
The invention features a method of determining whether one or more members of an analyte family are present in a sample. The method makes use of a test zone binder, e.g., a receptor that can bind one or a plurality of analytes within an analyte family, the analytes family defined by similar structural binding sites. Members of an analyte family can have different detection level requirements and, therefore, additional analyte binders can be employed to adjust test sensitivity for a subset of the analytes in the analyte family individually, so that each analyte can be detected only if it is present in the sample above a predetermined threshold.

Elimination of trans-unsaturated fatty acid compounds by selective adsorption with zeolites
InactiveUS6229032B1Low yieldLow costFatty oils/acids recovery from wasteFatty acid hydrogenationPartial hydrogenationDouble bond
A novel process for the selective elimination of fatty acid compounds containing carbon-carbon double bonds in trans configuration from a substrate containing cis- and trans-isomers of said fatty acid compounds, by selective adsorption by a microporous zeolite material is disclosed. The pore size and shape of usable zeolite materials enable differentiation between cis- and trans-isomers of unsaturated fatty acid chains. The zeolite materials used have a selectivity ratio alphatrans / cis higher than 1.00; this ratio is defined based on the elution properties of cis and trans double bond containing fatty acid methylesters dissolved in n-hexane during a column chromatography experiment with the zeolite material as the stationary phase and n-hexane as the mobile phase. Besides selective adsorption of trans-unsaturated fatty acid compounds, simultaneous or subsequent total or partial hydrogenation of the double bonds in said compounds can be carried out while using the same or similar zeolite material, containing finely dispersed catalytic active metals. The majority of these catalytic active sites must be inside the pores.

Partially hydrogenated fatty substances with a low content of trans fatty acids
A partially hydrogenated fatty substance produced by partial hydrogenation of a substrate, such as vegetable, animal or marine oil, said partially hydrogenated substance having a low content of trans fatty acids. When the hydrogenation degree is below 30% the trans-fatty acid concentration can be expressed in the following way: trans<=0.3x(initial IV-IV) in %. of the total amount of fatty acids, wherein IV refers to iodine value. When the hydrogenation degree is between 30 and 70% the trans-fatty acid concentration can be expressed with: trans<=0.09xinitial IV in % of the total amount of fatty acids. The partial hydrogenation is performed by a process in which the substrate, hydrogen gas and a solvent are mixed, and the whole mixture is brought into a supercritical or near-critical state. This substantially homogeneous super-critical or near-critical solution is led over the catalyst, whereby the reaction products formed, i.e. the hydrogenated substrates, will also be a part of the substantially homogeneous super-critical or near-critical solution.

Process and catalyst for production of low trans fat-containing triglycerides
InactiveUS20080161588A1Improve product appearanceImprove textureFatty acid hydrogenationFatty acids production/refiningVegetable oilHydrogenation process
Hydrogenated vegetable oil exhibiting superior thermal stability and containing reduced levels of saturates and trans fatty acids are produced using an activated hydrogenation catalyst and / or an improved hydrogenation process incorporating high shear. The use of a high shear mechanical device incorporated into the hydrogenation process as a reactor device is shown to be capable of enabling reactions that would normally not be feasible under a given set of reaction pressure and temperature conditions. For example, the hydrogenation process described herein enables a reduction of hydrogenation time, and operation at lower temperatures than current processes. The resulting hydrogenated vegetable oil is particularly useful in frying, confectionery baking, and other applications where a product with a low trans fat content or higher thermal stability is desirable. The hydrogenated oil produced may comprise less than 10 weight % of trans fatty acids with less than 5 weight % of linolenic acid (C18:3).
