| Abstract |
Green extraction using air-assisted, low-density solvent-based liquid–liquid microextraction and solidified
floating organic droplets (AA-LDS-LLME-SFOD) prior to spectrophotometry was successfully applied
for quantitation of carotenoids in fruit juices. Under optimal conditions, b-carotene could be quantified
with a linear response up to a concentration of 60 lg mL1. The procedure was performed in a microcentrifuge
tube with 40 lL of 1-dodecanol as the extraction solvent and a 1.0 mL juice sample containing 8%
NaCl under seven extraction cycles of air pumping by syringe. This method was validated based on linearity
(0.2–30 lgmL1, R2 0.998), limit of detection (0.04 lgmL1) and limit of quantification
(0.13 lgmL1). The precision, expressed as the relative standard deviation (RSD) of the calibration curve
slope (n = 12), for inter-day and intra-day analysis was 4.85% and 7.92%, respectively. Recovery of bcarotene
was in the range of 93.6–101.5%. The newly proposed method is simple, rapid and environmentally
friendly, particularly as a useful screening test for food analysis. |
