    Abstract: Disclosed is linoleic acid isomerases and their application in production of conjugated linoleic acid, which belongs to the technical fields of protein engineering and microbial engineering. The linoleic acid isomerase derived from Bifidobacterium is used to produce the conjugated linoleic acid. The recombinant E. coli containing the linoleic acid isomerase of the invention is added into a reaction system containing linoleic acid and react for 3 h to produce conjugated linoleic acids. The conversion rate of the conjugated linoleic acid of the invented method ranges from 12.1% to 42.1%, and the percentage of cis9, trans11-CLA in the conjugated linoleic acid can reach 84.3% to 89.1%. The invention provides a method for using microorganisms to produce conjugated linoleic acids with high safety and yield where cis9, trans11-CLA isomer is the major form in the conjugated linoleic acid products.

    Abstract: Disclosed is a diacylglycerol acyltransferase 1, a recombinant Saccharomyces cerevisiae containing the diacylglycerol acyltransferase 1, and application thereof in production of triacylglycerol. The diacylglycerol acyltransferase 1 of the invention has a function of catalyzing synthesis of triacylglycerol. After the recombinant Saccharomyces cerevisiae containing the diacylglycerol acyltransferase 1 of the invention is subjected to induction culture for 48 h, the content of total fatty acid and triacylglycerol in the recombinant Saccharomyces cerevisiae containing the diacylglycerol acyltransferase 1 can be respectively increased by 1.94 folds and 12.09 folds as compared with those of Saccharomyces cerevisiae without the recombinant diacylglycerol acyltransferase 1. The instant invention provides a method for improving the ability of microorganisms to produce polyunsaturated fatty acids (PUFAs) by means of genetic engineering.

    Abstract: A food thickener is provided in the form of agglomerated instant starch, which contains a combination of one or more pregelatinized starches and a specific water-soluble food ingredient possessing specific surface active functionality. The pregelatinized starch component can be either modified or native, and the water-soluble coating agent comprises a member selected from the group consisting of gum arabic, 1-octenyl succinic anhydride treated gum arabic, 1-octenyl succinic anhydride treated starches, 1-octenyl succinic anhydride treated maltodextrins, 1-octenyl succinic anhydride treated dextrins, and mixtures of any two or more of these. This novel thickener is comprised of more than about 50% pregelatinized starch and at least about 0.01% of a water-soluble food ingredient possessing surface active functionality. The thickener is useful in foods to provide spoon-stir dispersibility without lumping and can exhibit high and virtually instant viscosity development with little or no after thickening and are stable to long periods of storage. The thickener provides a smooth appearance and texture with high sheen.
