Abstract
A process for preparing an acid resistant cellulose capsule. An example of a process for preparing an acid resistant cellulose capsule includes the steps of: i) preparing 100 wt part of aqueous solution of solubilized cellulose including 15-25 wt part of cellulose; ii) sequentially adding and solubilizing: 2.0-4.0 wt part of amid pectin and 0.1-1.0 wt part of iota-carrageenan as a gelling agent, an auxiliary gelling agent, a pH neutralizing agent, an emulsifying agent, a viscosity stabilizing agent and a plasticizing agent to the resulting admixture; and iii) allowing it to stand and to be equilibrated with adjustment of viscosity, before forming the capsule.
Claims6
A process for preparing an acid resistant cellulose capsule, the process comprising:
- i) preparing 100 wt part of aqueous solution of solubilized cellulose including 15-25 wt part of cellulose;
- ii) adding and stirring 2.0-4.0 wt part of amide pectin and 0.1-1.0 wt part of iota-carrageenan as a gelling agent, and 0.01-0.2 wt part of potassium carbonate and 0.01-0.2 wt part of calcium gluconate as an auxiliary gelling agent to the aqueous solution of solubilized cellulose;
- iii) sequentially adding and stirring 0.01-0.1 wt part of glacial acetic acid as a pH neutralizing agent, 0.01-0.2 wt part of sucrose fatty acid ester and diacetylated monoglyceride as an emulsifying agent, 0.01-0.1 wt part of colloidal silica as a viscosity stabilizing agent, and 0.01-0.1 wt part of glycerin, PEG 4000 and/or propylene glycol as a plasticizing agent to the resulting admixture to create an obtained product;
- iv) allowing the obtained product to stand and to be equilibrated;
- and
- v) forming and drying a cellulose capsule.
