Abstract:
1. A process for preparing a dry carnitine powder or granulate from a liquid starting material containing carnitine and accompanying substances, said process comprising the steps of: a) obtaining a liquid starting material comprising an unpurified fermentation broth formed by a biocatalytic process for the production of carnitine in a liquid medium; b) subjecting the liquid starting material of step a) to one purification or one separation step to obtain a pre-purified liquid starting material containing carnitine and accompanying substances, wherein the pre-purified liquid starting material contains an amount of total dry matter, wherein the accompanying substances in the total dry matter is in the range of 10% to less than 50% of the total dry matter; c) mixing the pre-purified starting material of step b) with a carrier; d) subjecting the mixture obtained in step c) to a drying process, wherein the drying process occurs after only one purification or one separation step being performed on the liquid starting material; and e) recovering a stable dry carnitine powder or granulate, wherein the content of the accompanying substance of the pre-purified starting material in the recovered carnitine powder or granulate is less than 10% and wherein the carnitine is 1-carnitine, an alkanoyl-1-carnitine, a salt thereof or a mixture thereof.
