Abstract
The invention relates to a complex gum which takes curdlan as a main ingredient and application of the complex gum in microcapsule preparation. The complex gum comprises 50-70 parts of curdlan by weight and 30-50 parts of sodium alginate by weight. A microcapsule containing the complex gum provided by the invention has the advantages that the swelling property is greatly improved, the mechanical strength of the microcapsule is increased, and the mechanical strength is not influenced by the concentration, the pH and the like.
Description
Technical field
The present invention relates to the application of a kind of gum blend in the microcapsule preparation, belong to biological technical field.
Background technology
Curdlan (has another name called: curdlan) be a kind of fermentation polysaccharose substance of being found through microbial fermentation by the doctor of Osaka, Japan at that time in 1966.This material is because of having the characteristic (Curdle characteristic) that can solidify after the heating, so be named curdlan (Curdlan).It has following a few specific character:
1. solvability: curdlan can be dissolved in alkaline aqueous solution, but is not dissolved in water.Though curdlan can not be dissolved in water, be easy to be dispersed in the cold water, and processing forms the more diffusing liquid of uniform water through high-speed stirring.Curdlan can be dissolved in the above basic soln system of pH12 such as sodium hydroxide, tsp, tricalcium phosphate fully.
2. gelation: the colloid that can form heat irreversible property after the aqueous dispersions of curdlan is heated to more than 80 ℃.The colloid that is formed by curdlan can be divided into low level gel and high-order gel by its character.Be cooled to approximately below 40 ℃ after low level gel (thermal reversibility) is heated to about 55 ℃～65 ℃ to the aqueous dispersions of curdlan again, just can form the low level gel of thermal reversibility.When this low level gel is heated to about 60 ℃ again, can return to original aqueous dispersions state.When the low level gel is heated to the high-order gel that then can form heat irreversible property more than 80 ℃.Be stirred and after pulverizing at the low level gel, still can be formed into low level gel and high-order gel again through heating.The low level gel of same curdlan concentration is than the colloid weak strength of high-order gel.High-order gel (heat irreversible property) more than 80 ℃ the time, just can form the high-order gel of strong heat irreversible property to the aqueous dispersions direct heating of curdlan to about.High-order gel just can not be returned to original state again in case pulverize the back.
Microcapsule method is a kind of preparation method in the entrapping method, is meant with the fixing microcapsule of biological tissue or cell of semi-permeable membrane, enables to use repeatedly.
Microcapsulary is widely used in the fields such as separation purification, WWT and medicine controlled releasing of immobilization, protein and other compounds of animal and plant cells, mikrobe and enzyme, and the physical strength of microcapsule is to influence the important performance indexes that can it carry out practical application.
Summary of the invention
One object of the present invention is, a kind of gum blend is provided, and reduces the microcapsule physical strength and receives the factor of ectocine, thereby make it can better be applied to reality.
The preparation of novel built glue of the present invention is operated as follows:
Curdlan 50-70 weight part;
Sodium-alginate 30-50 weight part.
(1) prepares above-mentioned raw materials curdlan and sodium-alginate by proportioning;
(2) mixture is mixed get final product.
The technical scheme that novel built glue of the present invention is applied to microcapsule is following:
(1) gum blend is scattered in the normal-temperature water, stirs;
(2) leave standstill 1 hour, make solution be a stable collosol state;
(3) accomplish subsequent operations according to the present preparation method of bio-microcapsule, obtain complete microcapsule.
The present invention makes it well in the microcapsule preparation, overcome unfavorable factor through composite a kind of novel microcapsule compounded glue, and more favourable technical guarantee is provided, and makes bio-microcapsule in practice, can obtain more effective performance.
