Abstract

Nanostructured lipid carriers (NLC) can prevent the exposure of citral to an acidic environment and can inhibit the undesirable degradation of citral in acidic beverages.To investigate the ameliorative effect of NLC on citral degradation in acidic beverages, hydrogenated lecithin (HPC) and sunflower phospholipid (PC) were compounded with Spectrum 65 as surfactant and diethylstearic glycerol, medium-chain triglycerides and citral as lipid phase, two NLCs were prepared for basic characterisation and scanning electron microscope (SEM) analysis.To study the effect of the two NLCs on the beverage system, a blank group, a citral group, a HPC group, and a PC group were set up.The quality of the beverages stored at 4, 25, and 37 ℃ for 45 days was compared. Results showed that both NLCs were capable of inhibiting the degradation of citral in beverages, and HPC-NLC had better stability (particle size 145.5 nm, polydispersity index 0.216, Zeta potential -56.8 mV), the relative turbidity of the corresponding system at 4 and 25 ℃ was basically maintained above 90%, and the system pH was maintained in the range of 3.37 to 3.57, with better sensory quality.There were some correlations between sensory scores and pH, turbidity and relative turbidity.HPC-NLC showed higher stability in acidic beverages and better inhibition of citral degradation, providing a reference for the application of NLC and citral in the beverage industry.

Key words： nanostructured lipid carriers; citral; sunflower phospholipids; hydrogenated lecithin; acidic beverages
