Kehinde Oludayo Aremu Are you looking for non-dairy dairy application or within the dairy application? If you are looking for non-dairy application then you are free to form any formulation with plant based ingredients.
For dairy application, you can go with UF milk hydrolyzed with a controlled hydrolysis using lactase enzyme (for the removal of a residual lactose present after UF treatment) or you can use lactose free dairy powders to avoid UF milk hassle. I hope, this info. gives you an answer that you are looking for.
