文摘
- •
A novel method of AA-LDS-LLME-SFOD was first reported for β-carotene analysis.
- •
The low density and melting point of 1-dodecanol were exploited for floating drop extraction.
- •
Formation of cloudy solution by syringe prevented the need for an organic disperser solvent.
- •
A simple and rapid screening test was developed for determination of carotenoids in fruit juices.
