Abstract
This invention provides a process for preparing a cellulose capsule enhancing mechanical film strength comprising the steps of: i) preparing a mixed solution of iota-carageenan and agar; ii) adding said mixed solution to an aqueous solution of solubilized cellulose; iii) adding sucrose fatty acid ester, potassium pyrophosphate and glacial acetic acid to the resulting admixutre; and iv) allowing obtained product to stand, adjusting its viscosity and forming a capsule from it.
