The Effect of Sustained-release Rose Flavor of Different Rheological Properties on Perfuming
Abstract: Rose flavor loaded nanoparticle and microencapsulation of rose perfume with hydroxypropyl-β-cyclodextrin wall were successfully prepared. By changing the emulsifier, flavor content and wall material content, different nano-rose fragrance microcapsules of rheological properties were prepared. The teady and dynamic test were made. The nano-rose fragrance were applied in the cotton fabrics as aromantic reagents by impregnation. When chitosan as wall materials, the aromatic cotton gained the highest score of 9.7 . In this system, sustained-release flavor viscosity was the moderate，system storage modulus (G’) was the highest. When HP-β-CD as wall materials, the aromatic cotton gained the topest score of 9.2. In this case, the viscosity of this system was the lowest. Then, sensoty evaluations was made and analysis the relationship between results and the rheological property. The aromatic cotton fabrics were characterized with scanning electron microscopy (SEM), thermogravimetric analysis (TGA), gas chromatography-mass spectrometry (GC-MS) and solid-phase micro-extracion gas chromatography-hydrogen flame ionization detector(SPME-GC-FID) respectively. That sustained-release flavor had been fixation on the cotton fiber and the released property of microencapsulation treated cotton fabrics proved to be good under washing.
