Encapsulation of cholecalciferol and ergocalciferol in oil‐in‐water emulsions by different homogenization techniques Nauman Khalid, Isao Kobayashi, Marcos A. Neves, Kunihiko Uemura, Mitsutoshi Nakajima, and Hiroshi Nabetani DOI: 10.1002/ejlt.201600247 Ergocalciferol and cholecalciferol are bioactive compounds whose deficiency in human system results in rickets, osteoporosis and osteomalacia. Different homogenization methods were used to formulate stable food‐grade oil‐in‐water (O/W) emulsions encapsulating a mixture of ergocalciferol and cholecalciferol. The O/W emulsions formulated under appropriate homogenization conditions remained stable in terms of variation of their volume mean diameter over 30 days. Release profile of ergocalciferol and cholecalciferol encapsulated in the O/W emulsions was little affected by the homogenization methods used.
