    摘要: A method has now been found for the preparation of calcium, magnesium, and zinc salts of sugar acids, this being the object of the present invention, which is characterized in that the method may include providing a sugar and oxidizing the sugar to a sugar acid in the presence of a noble metal catalyst, oxygen, and a heterogeneous hydroxide source. Preferably the oxidation is carried out with a gold catalyst, and a heterogeneous source of magnesium, calcium, or zinc hydroxide. The oxidation can be performed in a batch or continuous manner.
