| titleOfInvention | Manufacture of ascorbyl monophosphates |
| abstract | The invention includes reacting L-ascorbic acid 2-polyphosphate with concentrated aqueous solution of an alkali metal or alkaline earth metal salt of L-ascorbic acid under alkaline conditions, wherein the L-ascorbic acid salt, and alkali used as base Adjust the amount of earth metal hydroxide so that the pH value of the reaction medium is maintained in the range of about 8 to about 11, and in each case one phosphate group until polyphosphate is consumed essentially and only L-ascorbic acid 2-monophosphate salt is present. A process for the preparation of alkali and alkaline earth metal salts of L-ascorbic acid 2-monophosphate, stepwise from polyphosphate to L-ascorbic acid salts. It is preferable to produce L-ascorbic acid 2-polyphosphate in situ and use calcium hydroxide as the base. Regardless of whether L-ascorbic acid 2-polyphosphate is produced separately or in situ, sodium trimetaphosphate is preferably used as the phosphorylating agent. A further aspect of the invention includes spray drying, cooling and diluting the mixture obtained after completion of the reaction to have a suitable viscosity. The products by the process according to the invention are suitable as additives for human food and animal feed, in particular stable to oxidative degradation and thermal decomposition, and in particular have a higher content of L-ascorbic acid monophosphate than polyphosphates. Preferred for use primarily for nutritional supplementation of fish food. |
