PROCESS FOR PREPARING CRYSTALLIZED GLUTAMIC ACID PREFERABLY IN THE FORM OF ITS SODIUM SALT OR MSG; GLUTAMIC ACID, MSG, SALTS AND ORGANIC CONCENTRATE OBTAINED BY THIS PROCESS

摘要

THE INVENTION CONCERNS A PROCESS FOR THE PREPARATION OF GLUTAMIC ACID IN A CRYSTALLIZED STATE, PREFERABLY IN THE FORM OF ITS MONOSODE SALT OR MSG. /P P THIS PROCESS INCLUDES A STEP OF ULTRA-FILTRATION OF THE MUST CLOSED GETTING A PERMEAT AND A RETENTAT AND IS CHARACTERIZED IN THAT IT FOLLOWS, THE FOLLOWING STEPS: A.WE CONCENTRATE PERMEAT PREFERABLY BY EVAPORATION BY OBTAINING A CONCENTRATED JUICE OF GLUTAMIC ACID AS WELL AS CONDENSATES; B.ON HYDROLYSIS THE RETENTAT BY ADDING CONCENTRATED SULFURIC ACID, THUS OBTAINING A HYDROLYSED RETENTAT; C. FILTERING THE HYDROLYSED RETENTAT BY OBTAINING A FILTER CAKE AND AN ACID FILTER JUICE; D. AT LEAST PART OF THE SAME IS ACID FILTER JUICE WITH THE SAME CONCENTRATED GLUTAMIC ACID JUICE TO CRYSTALLIZE GLUTAMIC ACID; E. PERFORM A FILTRATION OF THE MIXTURE BY OBTAINING CRYSTALLIZED SEA WATER AND A PURIFIED GLUTAMIC ACID CAKE. /P P ACCORDING TO A PREFERRED STEP, THE PURIFIED OR PURE GLUTAMIC ACID IS ALSO SALIFIED BY ADDITION IN SODED WATER WITH A NEW FILTRATION BY OBTAINING A MOTOR SOLUTION OF SINGLE-SODED GLUTAMIC ACID OR MSG AND FINALLY ON CRYSTALLIZES THE MSG OF PREFERENCE BY CONCENTRATION BY EVAPORATION. MSG CRYSTALS ARE SEPARATED FROM CRYSTALLIZED AND DRY SEA WATER. THE PROCESS ALLOWS TO OBTAIN A MSG OF EXCELLENT PURITY AS WELL AS TO RECOVER SALTS AS WELL AS AN ORGANIC CONCENTRATE DIRECTLY MARKETABLE RESPECTIVELY AS FERTILIZER AND IN ANIMAL FEED.
