The use of Pickering emulsions (PE) as a delivery system of carotenoids and related hydrophobic compounds has arisen great interest in the scientific community due to their nontoxicity, safety, and long-term stability against different environmental conditions. In this line, designing suitable food gradebiopolymers for their use as stabilizers in carotenoid loaded PE is an emerging research trend with many challenges. Thus, this review describes the recent advances in using proteins, polysaccharides, and protein?polysaccharide complexes as stabilizing agents of carotenoid-loaded PE. Besides that, this review provides a critical updated understanding of the effects of processing and storage on the stability of carotenoids encapsulated in PE, which are critical to support PE applications. The sustained-release behavior of PEin the gastrointestinal tract (GIT) is a hot topic that was also discussed, as well as the challenges for the applications of PE in the food industry.
