Methods of using the compound in numerous applicable fields, particularly in human and animal food are also described. | 09-22-2011 |
20120277321 | METHOD FOR PREPARING A COMPOSITION COMPRISING A COMPOUND BASED ON VANILLIN AND ETHYL VANILLIN, RESULTING COMPOSITION AND USES THEREOF - A method for preparing a composition including a compound based on vanillin and ethyl vanillin is described. A resulting composition and uses thereof in many fields of application, in particular in human and animal food is also described. A method for preparing a composition including a compound based on vanillin and ethylvanillin in a vanillin/ethyl vanillin molar ratio of 2 is also described wherein the method includes: a step of melting a mixture of vanillin and ethyl vanillin, which are used in a molar ratio other than 2, with an excess of vanillin representing from 2% to 20% of the weight of the mixture; a step of solidifying same, by cooling to a temperature of less than or equal to 50° C.±1° C.; and a step of recovering the resulting composition including the new compound. | 11-01-2012 |
20130172617 | METHOD FOR PREPARING A COMPLEX OF AN ACID AND A METAL - The invention concerns a method for preparing a complex of an acid chosen from among methionine, 2-hydroxy-4-methylthiobutanoic acid (HMTBA) and lactic acid, and of at least one metal, starting from said acid and a mineral metal source, wherein the acid is caused to react with the mineral metal source in an extruder. | 07-04-2013 |
20130203863 | METHOD FOR PREPARING A COMPOSITION INCLUDING A COMPOUND CONTAINING VANILLIN AND ETHYLVANILLIN, COMPOSITION THUS OBTAINED AND USE THEREOF - A method for preparing a composition including a compound including vanillin and ethylvanillin is described. Also described, is a method of preparing a composition including a compound including vanillin and ethylvanillin according to a vanillin/ethylvanillin molar ratio of 2. The method can include an operation of co-granulating vanillin and ethylvanillin at a temperature of 50° C. to 57° C. in the form of a powder and in amounts such that the vanillin/ethylvanillin molar ratio is at least equal to 2, and an operation of lowering the temperature of the composition thus obtained to room temperature. | 08-08-2013 |
20140220214 | Method for preparing an aromatic composition including a compound containing two solids having organoleptic properties - A method for preparing an aromatic pulverulent composition having a melting point Tf, comprising: i) feeding at least two pulverulent elementary solids having organoleptic properties into a mixer, whose chamber has been preheated beforehand to a temperature T lower than Tf, such solids being separately fed into the mixer; ii) mixing the pulverulent elementary solids in the mixer, in the absence of any external liquid phase, at a temperature T lower than Tf, at least one of the pulverulent elementary solids being fed into the mixer at a temperature Ti, such that the mixing occurs under isothermal conditions at a temperature set at such temperature T; and iii) recovering the aromatic pulverulent composition. This method is particularly suitable for preparing a composition essentially including a vanillin and ethylvanillin compound. | 08-07-2014 |
