Novel strategy for enhancing the color intensity of β-Carotene: Enriching onto the oil-water interface

摘要: Abstract A novel strategy to enhance the color intensity of β-carotene (BC), namely, “interfacial enriching”, was developed in this work. As sole emulsifier W/O emulsion, BC particles were enriched onto droplet surface through emulsifying process. By increasing concentration oil phase from 1 mg/g 5 mg/g, average size emulsion decreased 92.2 ± 5.1 μm 34.0 ± 5.4 μm. Too low (e.g. ≤ 1 mg/g) or too high (e.g. ≥25 mg/g) yielded an insufficient coverage flocculation droplets. enriching interface, enhanced apparently at reflectance wavelength ranging 500 nm 700 nm, compared with that encapsulated within This enhancement due higher availability incident light for on interface than buried inside
