Description

Technical Field

[0001] The invention relates to the field of flavor sustained-release agents, and more specifically to a porous adsorption core flavor sustained-release agent and a preparation method thereof. Background Art

[0002] Fragrance sustained-release agent is a chemical substance used to control the duration and release mode of fragrance molecules, allowing the fragrance molecules to be released slowly, thereby achieving a more lasting fragrance effect. By controlling the release rate of fragrance molecules, the fragrance can last longer. Fragrance sustained-release agent can physically or chemically react with fragrance molecules to adjust their molecular structure and release mode, thereby improving the quality of the fragrance. The use of fragrance sustained-release agent can produce more stable, longer-release and high-quality fragrance products.

[0003] Most of the existing flavor sustained-release methods are to mix the flavor with materials such as agar and finally solidify under certain conditions to slow down the overflow of flavor molecules. However, in actual use, most flavor products on the market are mixtures of multiple flavor molecules, often containing polar flavor molecules and non-polar flavor molecules, both of which have different molecular structures and adsorption capacities. In the use of mixed flavors, simple sustained-release methods are difficult to adsorb and release polar flavors and non-polar flavors at the same time, making it easy for flavors to change in taste when used. Therefore, in order to solve the above problems, the existence of a porous adsorption core flavor sustained-release agent and its preparation method is crucial. Summary of the invention

[0006] Furthermore, the first auxiliary material includes agar and gelatin, and the agar and gelatin are used to provide a stable gel structure to control the release rate of the flavor and act as a stabilizer.

[0007] Furthermore, the second auxiliary material includes pectin and gum arabic, and the pectin and gum arabic are used as thickeners, stabilizers and emulsifiers to cooperate with the first auxiliary material to control the release rate of the flavor.

[0008] Furthermore, the third auxiliary material includes glucomannan and alginate, and the fourth auxiliary material includes galactomannan and sodium alginate.

[0009] According to another aspect of the present invention, there is provided a method for preparing a porous adsorption core flavor sustained-release agent, comprising the following steps:

[0011] S2, spice soaking: soaking the composite material solidified into a spherical shape with spices for 24-60 hours;

[0012] S3. Fragrance recovery: drives the unabsorbed fragrance to be recovered and reused.

[0018] The porous adsorption core flavor sustained-release agent and the preparation method thereof of the present invention have the following beneficial effects:

[0019] By setting up a porous adsorption core and a coating layer, the core can simultaneously adsorb non-polar or polar flavors, while the coating layer provides high-strength protection and stabilization. The processing method involves multiple steps, including material preparation, stirring and solidification, flavor soaking and flavor recovery. Through this method, a wide range of sustained-release composite flavors can be prepared, which effectively solves the problems of weak persistence of existing flavors and incomplete functions of sustained-release agents.

[0026] In this embodiment, the first auxiliary material includes agar and gelatin. Agar and gelatin are used to provide a stable gel structure to control the release rate of the flavor and act as a stabilizer. Both agar and gelatin have good gelling properties and stability. Their combined use can further enhance the stability of the system and ensure that the flavor will not be released too quickly or deteriorate during the sustained release process.

[0027] In this embodiment, the second auxiliary material includes pectin and gum arabic. Pectin and gum arabic are used as thickeners, stabilizers and emulsifiers to cooperate with the first auxiliary material to control the release rate of the fragrance. Pectin and gum arabic as thickeners and stabilizers can significantly improve the stability of the fragrance sustained-release agent and prevent the fragrance from stratifying or precipitating during storage and use. By adjusting the ratio of pectin to gum arabic, the release rate of the fragrance can be accurately controlled, so that the fragrance can maintain a stable release effect for a long time, thereby extending the persistence of the fragrance.

[0028] In this embodiment, the third auxiliary material includes glucomannan and alginate, and the fourth auxiliary material includes galactomannan and sodium alginate. The combination of glucomannan and alginate produces a synergistic effect, improves the viscosity and stability of the solution, and contributes to the uniform dispersion and slow release of the fragrance. The combination of galactomannan and sodium alginate can accurately control the release rate of the fragrance, so that the fragrance can maintain a stable release effect for a long time, thereby prolonging the persistence of the fragrance.
