EDIBLE FILM WITH PERSIMMON-RIND AND METHOD FOR PRODUCING THEREOF

摘要

PURPOSE: A production method of an environment-friendly edible film is provided to mix a specific plasticizer with an excellent physical property and a cross-linking agent with persimmon skin for producing the edible film. CONSTITUTION: Persimmon skin is finely cut, and a persimmon skin solution is produced. A plasticizer and a cross-linking agent are mixed with the persimmon skin solution to obtain a persimmon skin film solution. The persimmon skin solution is coated into a thickness of 0.1 mm, and dried. The cutting step is performed by using an autoclave, a homogenizer, and a high pressure homogenizer. 3-10 wt% of persimmon skin is added for the total amount of edible film. The persimmon skin solution is produced by the following steps: processing the persimmon skin using the autoclave at 100-140C and in the pressure of 0.05-0.15 MPa for 15 minutes; and homogenizing the processed persimmon skin using the homogenizer for 5-30 minutes, and high pressure homogenizing the persimmon skin under 10,000-15,000 psi for 1-10 times.
