    摘要: The invention relates to a process for the preparation of ascorbic acid-2-phosphate, which comprises reacting ascorbic acid or araboascorbic acid with ATP to produce ascorbic acid-2-phosphate in an aqueous medium in the presence of an effective amount of an enzyme derived from a microorganism and capable of catalyzing the enzymatic reaction of ascorbic acid or araboascorbic acid with ATP to produce ascorbic acid-2-phosphate and recovering the resultant ascorbic acid-2-phosphate from the reaction solution.
