Preservation of Amla Juice

To preserve amla juice, ensure that the quantity of the juice is equal to the capacity of the jar. For instance, 500 grams of amla juice should be stored in a 500 grams capacity glass or a plastic container. Add 2 tablespoons of sodium lactate and mix well. This juice can be preserved in the refrigerator for 8 to 10 months. Sodium lactate is easily available at a chemist or any store that sells food chemicals.
