Abstract
The invention provides a method for preparing a lecithin microcapsule. Polysaccharide and gelatin serve as wall materials, lecithin serves as a core, the optimal mass ratio of polysaccharide to gelatin is selected, lecithin is added into water first to be dissolved through ultrasonic waves and is subjected to ultrasonic treatment along with the wall materials, and the lecithin microcapsule is obtained after spray drying. The prepared lecithin microcapsule has the good slow-release performance, is suitable for application in biology, and can be also used and popularized in the food industry.
Description
Technical field
The present invention relates to the preparing technical field of microcapsules, the preparation of specific design lecithin microcapsules.
Background technology
Microcapsules technology starts from the thirties in last century, and being attended by the most momentous results is in the fifties.Microcapsules technology is as a kind of new technology can improving material character, in the world microcapsules technology is classified as the new and high technology of 21 century primary study exploitation, current microcapsules technology develops rapidly abroad, particularly in Japan, the patent of the relevant microcapsules technology aspect of declaring every year just reaches up to a hundred.
Microcapsules technology is the technology that a kind of filmogen burden forms fine particle on a solid surface, and the material being enclosed in microcapsules inside is called core, and its size is generally within the scope of micron and millimeter.Wall material forms the material of microcapsule shell, and it must stable performance, does not react, and have certain intensity with core, heat-resisting, abrasion-resistant.The most frequently used wall material is natural macromolecular material, as starch, sugar, protein and glue.
The release of microcapsules core is the major criterion evaluating its performance.Release is divided into instantaneous relase and slow releasing two kinds, and Utopian microcapsules sample invades in the environment containing a large amount of medium, produces three kinds of processes: the medium permeates capsule wall material in environment enters in capsule core; In core, core dissolves and enters in medium and forms solution; The core medium solution dissolved is diffused into outside capsule by the high concentration region in capsule.The release performance of visible microcapsules core affects by the thickness of wall material film, the factor such as size, wall material deformation rate of wall film voidage.
To sum up, the principal element that performance is good, be suitable for practical microcapsules is prepared in the selection of wall material.
Summary of the invention
The present invention is directed to above problem in prior art, with the mixture of polysaccharide and gelatin for wall material, prepare the microcapsules that release performance is good.The present invention is achieved through the following technical solutions:
