starch or gum arabic is used. This means that both are carrier materials that provide better protection against oxygen, Jger said.
The method of powder manufacture also has an enormous influence on storability with the physical barriers to oxygen again proving decisive. If the powder is produced by means of freeze drying, powder particles contain micropores and nanopores that allow oxygen to penetrate quickly.
But by using an optimised spray drying process, which produces denser particles wit
