“…In many cases, researchers first developed a colloidal delivery and then check if it is compatible with a specific food matrix on a trial-and-error basis. In future, it will be important to consider these factors early on within the particle design process when developing fortification strategies for vitamin D. Despite these reservations, some researchers have already developed vitamin D-loaded delivery systems that have been successfully incorporated into different target food products, for example, casein micelles in yogurt (Levinson et al, 2016), protein nanoparticles in mayonnaise (Khan et al, 2020), liposomes in yogurt (S. M. Jafari et al, 2019), nanoemulsions in yogurt (Maurya & Aggarwal, 2017c), liposomes in milk (Mohammadi et al, 2014), liposomes in cheese (Al-mosowy et al, 2021;Mohammadi et al, 2015), NLCs in milk (Kiani et al, 2017), NLCs in lassi (Maurya & Aggarwal, 2019a), NLCs in buttermilk (Maurya & Aggarwal, 2019b), NLCs in beverages (Mohammadi et al, 2017), microparticles in juice (Dima, Milea, et al, 2020), starch-based nanoparticles in milk (Hasanvand et al, 2015(Hasanvand et al, , 2018, gum arabic-based nanoparticles in beverages (Lamsen, 2020), and lipid nanoparticles in plant-based milk (Zhou et al, 2021a).…”
