METHOD FOR PRODUCING SHELLS based on chitosan and salts of alginic acid FOR microcapsules containing phospholipid MICELLES

摘要

1. A method of producing shells on the basis of chitosan and alginic acid salts for microcapsules containing phospholipid micelles, characterized sequential exposure microcapsule cores in 0,5 ÷ 1,0% (wt. / Vol.) Solution of chitosan medium or low viscosity 1.0 % acetic acid at 2.5 ÷ 3.0% solution of alkaline earth metal chloride, a 0.5 ÷ 1.0% (wt. / vol.) sodium alginate solution and, again, a 2.5 ÷ 3.0% alkaline earth metal chloride solution. ! 2. A method according to claim 1, characterized in that the microcapsules are kept in a chitosan solution 25 ÷ 30 minutes, a solution of an alkaline earth metal chloride, - at least 25 ÷ 30 minutes, a solution of sodium alginate - at least 5 ÷ 10 minutes, again in a solution alkaline earth metal chloride, - at least 10 ÷ 15 minutes. ! 3. A method according to claim 1, characterized in that the alkaline earth metal chloride, calcium chloride is used. ! 4. A method according to claim 1, characterized in that the alkaline earth metal chloride is used barium chloride.
