Kinetic models applied to soluble vitamins delivery systems prepared by spray drying

Abstract

The incorporation of bioactive nutrient compounds such as vitamins into food systems can providea simple way to develop new functional foods. In this work, the controlled release of two vitamins(vitamins B12 and C), microencapsulated by a spray-drying process, is studied. With a properlydesigned controlled-release system, the compounds are released at the desired site and time, andat a desired rate. The main kinetic release models are applied and discussed. Also, the mainmechanisms associated to the release were identified. The use of models to predict in vivobio-performance is an advantage in the development of new products.
