Abstract

The design of appropriate thermally responsive fragrance carrier systems is of significant importance for the application of fragrance in the food and tobacco industries. In this study, we investigate the potential of sorbitan monostearate and guar gum for the stabilization of menthol under ambient conditions and the thermally-induced release of menthol. Our results show that the sorbitan monostearate carrier could well stabilize the menthol for at least up to 15 days with neglectable menthol loss due to the favorable binding of menthol on the sorbitan monostearate carrier. In addition, rapid and controlled release of menthol could take place at a temperature of 80 °C in the sorbitan monostearate carrier system. As a comparison, guar gum could not stabilize menthol as a result of its poor compatibility. Our results suggest that sorbitan monostearate can be an ideal carrier material for the support of fragrance. In addition, our results also provide a useful guide for the tailored design of thermally responsive fragrance carriers.

Summary

Introduction

Fragrance is widely used in daily care and food products, such as soap, detergent, cosmetics, drinks, candy, and so on. The use of a proper carrier for fragrance is an ideal approach that can potentially stabilize and release fragrance on-demand, simultaneously [2,3,4,5,6,7,8,9,10,11,12]. Among all the fragrance carriers, thermal-responsive fragrance carriers are an important type of carrier material commonly used in a wide range of fields such as the tobacco industry [13]. A suitable carrier should be non-toxic to secure its use in daily products. The carrier should have an intermediate binding strength with the fragrance, which is important for the on-demand perseverance and release of the fragrance. An ideal carrier material should be cost-competitive to enable large-scale application. The constraints above make an appropriate choice of carrier material challenging
