In recent decades, there has been a reduction in the consumption of some animal products due to the search for healthy products. In the case of dairy products, fat is an important source of conjugated linoleic acid (CLA), a set of bioactive isomers, some with beneficial effects for human health, for example, in the prevention of diseases such as Alzheimer's. The manipulation of ruminant diet has been the used alternative to change milk composition and, thus, producing CLA-rich milk products. Additionally, the use of nanostructured systems makes it possible to carry the active principle by means of alternative routes of administration. In this regard, this project was conducted with the objective of developing a nanostructured system for pharmaceutical and cosmetic applications and adding value to milk fat. The project had the support of Pharmacy Colleges of UFJF (Federal University of Juiz de Fora) and UFSC (Federal University of Santa Catarina).
