PENGEMBANGAN PROSES COMPRESSION MOLDING DALAM PEMBUATAN EDIBLE FILM DARI TEPUNG KORO PEDANG (Canavalia ensiformis L.) [Development of Compression Molding Process for Edible Films Production from Canavalia ensiformis (L.) Flour]
Edible Films based on Canavalia Ensiformis flour could be made using compression molding process. This research was to investigate temperature (120oC, 130oC, 140oC) and pressure ( 0.845 Mpa, 1.690 Mpa, 2.540 Mpa) effect on the properties of the film. The compression-molding pressure significantly a...

Summary: | Edible Films based on Canavalia Ensiformis flour could be made using compression molding process. This research was to investigate temperature (120oC, 130oC, 140oC) and pressure ( 0.845 Mpa, 1.690 Mpa, 2.540 Mpa) effect on the properties of the film. The compression-molding pressure significantly affected the film’s thickness, lightness, tensile strength, elongation and Water Vapor Transmition Rate (WVTR). Meanwhile molding temperature only affected film’s elongation (P<0.05) over the range of conditions studied. Increase in compaction pressure resulted in decreased thickness, tensile strength, elongation with increase in lightness (L*) and WVTR. Increasing the molding temperature decreased elongation. Flexible, light-yellow edible films could be produced at a processing temperature of 140oC and compaction pressure of 0.845 Mpa. The films thickness was 0.302 mm; lightness (L*) was 68.557, tensile strength was 4.091 Mpa, elongation was 37.547 % and WVTR was 0.001 mg/m2.det. |
