Perspective on oleogelator mixtures, structure design and behaviour towards digestibility of oleogels

The concepts of either multi-component supramolecular gels or structures derived from oleogels have not yet been fully investigated to their respective potentials. The study of hybrid structures might cover technological points such as (i) how to vehiculate hydrosoluble and/or liposoluble bioactive components simultaneously? (ii) How could the framework of an oleogel contribute to a specific structure design strategy? (iii) How does oleogels structure influence bioactivity during digestion? A deeper understanding of these issues widens the range of opportunities foreseen for oleogel applications in food matrices. This paper presents the most relevant developments in the field, including the role of ingredients on structured oil-based systems. The authors perspective towards digestibility of oleogels and oleogel-derived structures is also addressed.Paula Kiyomi Okuro thanks FAPESP (grant #2018/20308-3 São Paulo Research Foundation -FAPESP).
