Encapsulation of bioactive compounds for the formulation of functional animal feeds: The biofortification of derivate foods

This is an accepted manuscript of an article published by Elsevier in Animal Feed Science and Technology on 23/07/2021, available online: https://doi.org/10.1016/j.anifeedsci.2021.115036 The accepted version of the publication may differ from the final published version.Microencapsulation is a technology that has increasing application in animal nutrition. This technology provides the possibility to protect sensitive compounds through the feed process and the storage conditions. Furthermore, the application of this technique affords the possibility to increase the bioavailability of compounds and to mask the unpalatable compounds taste. Different are the compounds to consider for microencapsulation include certain vitamins, amino acids, fatty acids, organic acids and live microorganisms. Understanding the interdependence between bioactive compounds, coating, technology and environment is the key to successful application of microencapsulation also in animal nutrition. In this review, a focus on the use of microencapsulated bioactive compounds for the feed supplementation and the related effects on the derivate animal product is given.The study was financially supported by MILK BIOACTINCAPS project ���Use of microencapsulates of bioactive compounds from food industry waste as feed supplements for the improvement of the fermentative aptitude and nutraceutical value of milk��� funded by the Italian Ministry of Agriculture, Food and Forestry Policies, Mipaaft (Ministry Decree n. 27443 of 25.09.2018).Accepted versio
