Abstract
Temperature-sensitive nanocapsules with controllable release properties were synthesized through miniemulsion free radical polymerization method. Temperature-sensitive N,N-diethylacrylamide/N,N-dimethylacrylamide (DEA/DMA) copolymer were systematically synthesized as shell materials, and the fragrance-dementholized peppermint oil (DPO) was encapsulated as hydrophobic core material. The as prepared nanocapsules had high encapsulation efficiencies of more than 90% and small average diameters of less than 150 nm, as well as narrow polydispersity index (PDI) below 0.17. Furthermore, decreased DEA contents in shell material resulted in higher phase transition temperature and slower release rate of fragrance under the same temperature. By varying the copolymer composition of shell materials, the controllable release property of as prepared nanocapsules were also varied under different temperatures.
期刊介绍：
Flavour and Fragrance Journal publishes original research articles, reviews and special reports on all aspects of flavour and fragrance. Its high scientific standards and international character is ensured by a strict refereeing system and an editorial team representing the multidisciplinary expertise of our field of research. Because analysis is the matter of many submissions and supports the data used in many other domains, a special attention is placed on the quality of analytical techniques. All natural or synthetic products eliciting or influencing a sensory stimulus related to gustation or olfaction are eligible for publication in the Journal. Eligible as well are the techniques related to their preparation, characterization and safety. This notably involves analytical and sensory analysis, physical chemistry, modeling, microbiology – antimicrobial properties, biology, chemosensory perception and legislation.
The overall aim is to produce a journal of the highest quality which provides a scientific forum for academia as well as for industry on all aspects of flavors, fragrances and related materials, and which is valued by readers and contributors alike.
