Nanoemulsion delivery systems: Influence of carrier oil on β-carotene bioaccessibility

► β-Carotene can be encapsulated in nanoemulsions using different carrier lipids. ► Carrier lipid type influences β-carotene bioaccessibility. ► Long chain triglycerides lead to high bioaccessibility. ► Orange oil and medium chain triglycerides lead to low bioaccessibility.
