Abstract

The invention provides a controlled release type yeast cell microcapsule product and a preparation method thereof and relates to culture and treatment of yeast cells. A microcapsule wall material is obtained and subjected to hole sealing modification, and the microcapsule product is obtained. Yeast cells subjected to shake-flask culture under the proper condition are treated with chemical reagents such as lauryl sodium sulfate, dithiothreitol and the like, centrifuged, washed and then further treated with a sodium hydroxide solution. The yeast cells are centrifuged, washed and freeze-dried. After the yeast cell wall material and a to-be-embedded core substance solution are contacted at high frequency for encapsulation, hole sealing modification with cationic polymers is performed. Centrifugation is performed, the unencapsulated core substance and redundant cationic polymers on the surface are washed away, grinding is performed after freeze-drying, and the controlled release type yeast cell microcapsule which is uniform in size and not sticky is obtained.

Description

technical field

[0001] The invention provides a method for preparing controlled-release yeast cell microcapsules, which relates to methods for culturing and treating yeast cells, preparing microcapsules and sealing holes, and further relates to microcapsule wall materials and microcapsules prepared by the method. Capsule product. Background technique

[0002] Microcapsule technology wraps solid, liquid or gas (core substance) in another material (wall material), which can protect the core substance from the environment and control the release of the core substance. One of the key high-tech development. Encapsulation efficiency and burst release rate are the two most important indicators for evaluating microcapsule preparations, and they are also key technical issues that limit their wide application. The choice of wall material determines the quality of the prepared microcapsule product, and solving the high cost of preparation and the safety of wall material and auxiliary...
