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. The aroma sustained-release capsule comprises a composite microsphere, the composite microsphere comprises a plurality of microsphere units, a matched capsule shell is arranged outside the composite microsphere, and the diameter of the composite microsphere is smaller than that of the capsule shell. The invention also discloses a preparation method of the fragrance sustained-release capsule. The aroma sustained-release capsule is prepared from a starch-beta cyclodextrin composite microsphere and xanthan gum, so that the single use time of the original aroma releasing agent is prolonged to enhance the use effect, and the problems of resource waste, environmental pollution, harm to human health and the like caused by too high aroma volatilization speed and increased use times in the prior art are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of sustained-release capsules, in particular to an aroma sustained-release capsule and a preparation method thereof. Background technique [0002] At present, in our country, the demand of various groups of people for a series of aroma release agents such as fragrances, aromatherapy, and mosquito repellent water has increased significantly. In the early stage of the arrival of new revolutionary technologies, there are many problems in existing products. , Most of the aroma release agents for one-time use volatilize too quickly. If you need to enhance the use effect, you can only increase the number of times the product is used. However, this method will cause serious waste of resources and also put a lot of pressure on the environment. There are a large part of aroma release agents that are harmful to human health during use. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in...
