Problems solved by technology

[0003] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides an aroma sustained-release capsule and a preparation method thereof. An aroma sustained-release capsule is made by starch-β-cyclodextrin composite microspheres and xanthan gum to prolong the release of the original aroma. The single use time of the agent is used to enhance the use effect, which effectively solves the problems in the prior art that the aroma volatilizes too fast, increases the number of uses, causes waste of resources, environmental pollution and harm to human health.

Abstract

The invention discloses an aroma sustained-release capsule and a preparation method thereof. An aroma sustained-release capsule includes composite microspheres, the composite microspheres include several microsphere units, the exterior of the composite microspheres is provided with a matching capsule shell, the composite microspheres The ball diameter is smaller than the capsule shell diameter. The present invention also includes the preparation method of the fragrance sustained-release capsule. The present invention uses starch-β-cyclodextrin composite microspheres and xanthan gum to make aroma slow-release capsules, prolongs the single use time of the original aroma release agent to enhance the use effect, and effectively solves the problem of excessive aroma volatilization speed in the prior art. Fast, increasing the number of times of use causes waste of resources, environmental pollution and hazards to human health.

Description

technical field [0001] The invention belongs to the technical field of sustained-release capsules, and in particular relates to an aroma sustained-release capsule and a preparation method thereof. Background technique [0002] At present, in our country, the demand for a series of aroma release agents such as aromatherapy, aromatherapy, and mosquito repellant has increased significantly. At the stage where new revolutionary technology is too early, there are many problems with existing products. , Most of the single-use aroma release agents volatilize too quickly. If you need to enhance the use effect, you can only increase the number of times the product is used, but this method will cause serious waste of resources, and it will also put a lot of pressure on the environment, and A large part of the aroma release agents present health hazards to the human body during use. SUMMARY OF THE INVENTION [0003] In view of the above-mentioned deficiencies in the prior art, the p...
