ivity of specific bioactive components.
Amongst the convective air drying methods, spray drying is a mild technique due to its very short drying times and the relatively low temperatures to which the product is exposed However, compared to freeze or vacuum drying, the spray drying process is more prone to damaging heat sensitive components such as enzymes and probiotic bacteria, they noted.
However, because it could process much larger volumes and operated at a higher energy efficiency, spr
