Abstract: A process for producing a product having a fish flavor is provided, the process comprising preparing a composition comprising 1-20% w/w water and at least a polyunsaturated fatty acid, incubating the composition at less than 260° C. and at a reaction time sufficient for the fish flavor to develop, and optionally mixing the product with one or more other ingredients. The product obtainable by this process and methods for using the same are also provided.
Abstract: A process is provided for preparing urea-containing polymers by contacting a hydroxy-functional organic compound having a functionality of two or more, with a coupling agent in the presence of a strong base, wherein the coupling agent is a carbonylbislactam compound having the general formula (I): wherein n is an integer from 3 to 15, and that the contacting is conducted at a temperature between 0° C. and 80° C. The polymers thus obtained are believed to be new and are useful e.g. in tissue engineering and coatings applications.
Abstract: Ampicillin is produced in a batch process by enzymatic acylation of 6-aminopenicillanic acid (6-APA) with the aid of phenylglycine derivative such as D-phenylglycine amide. High conversions of phenylglycine derivative may be achieved by having the total concentration in the reaction mixture of 6-APA and ampicillin greater than 250 mM and the molar ration of total quantity of phenylglycine derivative to total quantity of 6-APA less than 2.5. Higher yields of ampicillin may be achieved when the amount of dissolved 6-APA is kept low, e.g. below 300 mM.
