Preparation of regenerated cellulose-vitamin E complex
摘要
This study aimed to enhance the stability of Vitamin E by loading with regenerated cellulose. NaOH/Urea solution of MCC was used to prepare the RC complex with VE via a solution method. The properties and storage stability of the complex were characterized using XRD, FTIR, CLSM, XPS and SEM. Three experimental factors of reaction temperature, weight ratio of MCC to VE, and reaction time were studied to prepare the RC/VE complex. The results indicate that the complex formed along with the regeneration of cellulose. The complex exhibited a type II cellulose lattice. At experimental conditions of 0 °C, the weight ratio of MCC to VE is 4:6, and the time of 2.5 h, the loading rate of VE reached a maximum. The storage stability of the RC/VE complex was improved by a 44.58% retention rate after 7 days of storage at 60 °C, compared to pure VE. The FTIR results showed that RC physically complexed with the VE molecule through hydrogen bond and hydrophobic forces.
