We have a product which is a clinically supported whole cranberry powder for urinary tract infections. This product is only 60% soluble in water and we are looking to make it 100% water soluble using microencapsulation technology.
If the material is only 60% soluble in water then use of microencapsulation technology will not make it more soluble. Is there some other reason aside from the structure of the material why it is only 60% soluble in water? Have you tried to grind it down into more a powder to see whether this will improve solubility?
