Functionalized Polymers for Enhance Oral Bioavailability of Sensitive Molecules.

Currently, many sensitive molecules have been studied for effective oral administration. These substances are biologically active compounds that mainly suffer early degradation in the gastrointestinal tract (GIT) and physicochemical instability, inactivation and poor solubility and permeability. The sensibility of the biomolecules has limited their oral administration in the body and today is an important research topic to achieve desired effects in medicine field.

Microfiltration applied to dairy streams: removal of bacteria.

Microfiltration applied in the dairy industry for bacteria removal is an important technology for extending the shelf life of milk while maintaining or even improving its organoleptic and nutritional properties. This article reviews the evolution of this technique over recent years and the advances currently being made in the field. The cited literature indicates the strategies used to overcome the main drawbacks of this type of operation, the most common operating conditions employed and the reduction degree of bacteria obtained.
