Research and Development of Fragrance Retention Technology

Abstract

Fragrance retention technology plays a pivotal role in the application of flavors and fragrances, particularly in industries such as cosmetics, food, and textiles, where enhancing the longevity of product scents is a growing demand. This paper provides a comprehensive review of the relationship between fragrance molecular structure and volatility, introduces key technologies including adsorption-based, encapsulation-based, and matrix-based carriers, and emphasizes the critical role of slow-release mechanisms in controlling fragrance diffusion. By utilizing various carriers and technical approaches, the release rates of fragrances can be regulated, significantly enhancing aroma persistence. Furthermore, the strategic use of fixatives and fragrance enhancers can further prolong scent duration and improve diffusion. However, current technologies face challenges, such as the stability of slow-release mechanisms and the potential impact of fixatives on fragrance profiles. Looking ahead, advancements in nanotechnology, biotechnology, and material science are anticipated to enable breakthroughs in precision-controlled fragrance release, fostering more intelligent and efficient aroma delivery systems and broadening their applications across multiple sectors.
