What does the SD in a product name stand for?
SD stands for spray dry, which is a method utilizing an atomizer to feed through the liquid with hot air blowing to dry the liquid. However, if the material is sensitive, nitrogen gas will be used instead of air. The liquid feed varies on the material being dried and is not limited to food or pharmaceutical products. It may be a solution, colloid or suspension. Vitamin E powder is one of the spray dried products offered at DNP.
