New thermal releaser of menthol: Cellulose acetate film covered amorphous silica
A new way of controllable releasing menthol with amorphous silica is reported for the first time. Porous silica adsorbed menthol in 373-413 K and then was covered with cellulose acetate film to form a carrier-embedded menthol. The sealed menthol would be released at elevated temperatures once the cover fractured. Here, the influence of temperature and nature of sorbent on the adsorption of menthol along with the covering manner were investigated carefully, and the thermal release of menthol was studied with headspace gas chromatography (HS-GC) method. Silica adsorbed about 400 mg g−1 of menthol at the optimal adsorption conditions and released most of them at about 473 K. Preliminary application in non-combustible cigarette proven the feasibility of thermal release of menthol with the covered silica carrier.
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.
