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. |
