Abstract
Fragrance is a commonly used substance in a number of commercial products, and fine control over the release behavior of the fragrance is essential for its successful application. Understanding the release behavior of the fragrance is the key to realizing the control of its release. Herein, we use tobacco leaf as the model substrate and investigate the mechanism of eugenol release from tobacco leaf. Our results show that interaction between eugenol and tobacco leaf is weak physical adsorption, and the eugenol release from tobacco leaf substrate is a temperature-dependent process. Further analysis on the release behavior reveals that eugenol release is closely associated with the morphology change of tobacco leaves under heating conditions. Our results provide insight into the release mechanism of fragrance from polymer substrate and may be useful for the future design of fragrance release systems.

Fragrance can bring a pleasant scent or help to shield unwanted smells
The observed release behavior is correlated with the microscopic interactions between eugenol and tobacco leaf
Tobacco leaf is a complex mixture mainly composed of cellulose, monosaccharide, starch, lignin, etc
Summary
Fragrance can bring a pleasant scent or help to shield unwanted smells. fragrances are widely used in a variety of commercial products ranging from consumable commodities to industrial goods. The affinity between the carrier and the fragrance should be designed to achieve both high stability of fragrance under storage conditions and desirable release behavior under working conditions. Direct loading of the fragrance onto the substrate material of the product is simple and more cost-effective than the use of fragrance carriers. It is challenging to achieve precise control over the release behavior of the fragrance on such a release system This is because that the interaction between the fragrance and substrate involves a series of complex interactions such as intra-molecular interactions and steric hindrance [11,12,13]. We use eugenol as the model fragrance and tobacco leaf as the substrate and investigate. The observed release behavior is correlated with the microscopic interactions between eugenol and tobacco leaf
