Abstract

The invention discloses a preparation method of a beta-cyclodextrin inclusion linseed oil microcapsule, and relates to the preparation method of the beta-cyclodextrin inclusion linseed oil microcapsule. The preparation method aims at solving the problems that linseed oil is easily subjected to oxidative rancidity, and is short in quality guarantee period, and not easy to be evenly mixed with food. The preparation method is achieved by the following steps: 1, dissolving beta-cyclodextrin into an ethanol solution of which the volume fraction is 50-60%; 2, adding absolute ethyl alcohol containing dissolved linseed oil to the solution obtained in the step 1; 3, ultrasonically agitating the solution obtained in the step 2 at certain temperature for 30-40 minutes, then standing, and finally, carrying out vacuum suction filtration, so as to obtain the beta-cyclodextrin inclusion linseed oil microcapsule. The preparation method is applied to the field of food healthcare.

Description

technical field [0001] The invention relates to a preparation method of β-cyclodextrin inclusion linseed oil microcapsules. Background technique [0002] Cyclodextrin is a wall material for microencapsulation, which has a hydrophobic inner cavity and a hydrophilic outer shell. This special molecular structure enables cyclodextrin to form inclusion complexes with suitable guests. When the guest molecule is enclosed in the cavity of cyclodextrin, its physical, chemical and biological properties will be beneficially changed, such as the improvement of solubility; the enhancement of stability to light, oxygen and heat; the control of volatilization and sublimation . Many natural and synthetic compound molecules, after undergoing some physical and chemical actions, are fully or partially wrapped into cyclodextrin empty cylinders to form complexes. Compound molecules are surrounded by hollow tubes, greatly reducing the contact with the surrounding environment, thus playing many ...
