Preparation and controlled release characterization of aroma-loaded temperature-sensitive gel beads
摘要
Abstract
Existing cigarette popping beads mainly use mechanical external force to destroy the release of flavors.They suffer defects of rapid and short-lived release of flavor substances.In this paper,temperature-sensitive gel beads are prepared using SA,NIPAM,APS,MBA,and TEMED as the substrate by using the freezing polymerization method.Their physical properties are determined by using FT-IR and SEM and then loaded with water-soluble flavors loaded in cigarette filter rods,and the flavors are released using high-performance liquid chromatography.The physical properties are determined by FT-IR and SEM;the water-soluble flavors are loaded into cigarette filter rods,and the release pattern of the flavors from the temperature-sensitive gel beads in the mainstream cigarette smoke is analyzed by HPLC.Our results show the temperature-sensitive gel beads are successfully prepared through FT-IR and SEM.According to the effects of different concentrations of SA on the performance of aroma-carrying temperature-sensitive gel beads,the 0.8％ SA group is selected as the optimal concentration for the preparation of temperature-sensitive gel beads;its equilibrium swelling rate is as high as 628％,and the rate of desolvation is fast,and the desolvation equilibrium is reached in 4 min.When the cigarette is smoked,the release of flavors from the 1 st-4 th puffs account for 28.65％ of the total release,and the release from the 5th-7th puffs and the 8th-10th puffs are 40.20％ and 31.14％,respectively;the release of flavors during the whole smoking process is more uniform and stable.关键词
