“…It is the technique by which sensitive ingredients are packed within a coating or wall material (Loksuwan, 2007). Different methods for encapsulation of β-carotene in appropriate delivery system, such as nanoemulsion (Liang et al, 2013;Qian et al, 2012), microemulsion (Donhowe et al, 2014), liposome (Lee et al, 2002), solid lipid nanoparticles (Cornacchia & Roos, 2011), and complex assemblies with macromolecules (Pan, Yao, & Jiang, 2007) are reported. Effectiveness of microencapsulation depends on the method employed (Donhowe et al, 2014).…”
