What is Encapsulated Ascorbic Acid?


Encapsulated Ascorbic acid is a more stable form of Vitamin-C that can be used in foods and dietary supplement products.  Encapsulated Ascorbic acid allows for reduced overages while better assuring end-of-shelf-life label claims due to more consistent survival through varied storage conditions.  Encapsulated Ascorbic Acid is used in baking to replace the gassing source of bromates.

Encapsulated Ascorbic Acid is ideal for nutrition bars, fortified foods, tablets and capsules.  It is effective because it protects vital nutrients without changing flavor profile or texture characteristics.  It also allows a reduction in usage compared to raw ascorbic alone.
