负载柠檬醛纳米结构脂质载体在酸性饮料中的稳定性研究
Research on stability of citral loaded nanostructured lipid carriers in acidic beverages
摘要
Abstract
Nanostructured lipid carriers(NLC)can prevent the exposure of citral to an acidic environment and can inhibit the unde-sirable degradation of citral in acidic beverages.To investigate the ameliorative effect of NLC on citral degradation in acidic beverages,hy-drogenated lecithin(HPC)and sunflower phospholipid(PC)were compounded with Spectrum 65 as surfactant and diethylstearic glycer-ol,medium-chain triglycerides and citral as lipid phase,two NLCs were prepared for basic characterisation and scanning electron micro-scope(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 size145.5 nm,polydispersi-ty index 0.216,Zeta potential-56.8 mV),the relative turbidity of the corresponding system at4 and25℃was basically maintained a-bove 90%,and the system pH was maintained in the range of 3.37 to 3.57,with better sensory quality.There were some correlations be-tween 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.关键词
