Abstract

Edible plastic usually made from hydrocolloids and could be produced by solvent casting method whereas gel was made before casting. Potential of whey protein combined with tapioca as edible plastic based component was studied at this research. pH of solvent could affect interaction of whey and tapioca during  gel preparation. The gel’s characters affected on plastic’s characters . The research objectives were to study effect of whey and tapioca ratio and pH of solvent on physical properties of gel and edible plastics. Randomized Factorial Block Design were used. The two factors  were  porpotion of whey protein-starch mixture (0%, 20%, 40%, 60%, 80%, 100%) and pH of solvent ( 4, 7 and 9). Increasing of whey porpotion could increase solubility of gel but decrease gel’s lightness and texture. Increasing of pH could increase gel’s solubility and decrease lightness and texture. There was significant effect (p≤0,05) of whey porpotion and pH interaction on gel’s characters. Increasing of whey porpotion could increase tensile strength and decrease elongation and solubility of edible plastics but the increasing of tensile strength was not significant (p≥0,05). Increasing of pH could increase elongation and decrease tensile strength and plastic’s solubility. There wasn’t significant effect (p≥0,05) of whey porpotion and pH interaction on edible plastic’s characters. The result showed that whey addition had decreased plastic’s characters even at 100% whey ratio tensile strength and elongation value were zero, edible plastic could not be produced from 100% whey. Keywords: texture, solubility, elongation, tensile strength, interaction

Abstract

Manufacture of biodegradable plastics in this study begins with making the dough using a single screw extruder, then the dough is molded by using a compression molding machine. The basic material used is a mixture of jatropha seed meal, corn starch, CMC (composition 7: 2: 1). This study aimed to study the effect of Helic corner and screw compression ratio of the batter character and biodegradable plastic produced. Helic screw angle was varied from 2,5o; 5o; 7.5 ° and screw compression ratio varied from 1.5; 2.5; 3.5. The results showed an increase in the angle of screw Helic simplify the process of molding (lowering the value of Tg, Tm, ΔH and texture of the dough) and to improve the mechanical physical properties of the biodegradable plastic produced (tensile strength, strain increases while the thickness and Water Vapor transmition rate decreases). Improved compression ratio increase and decrease the thermal properties of dough texture and increase the tensile strength and strain, decrease the thickness and Water Vapor transmition rate of biodegradable plastic produced. Keyword: biodegradable plastic, mold, helical degree, compression ratio

The extraction using combination of water and isopropanol at 270C showed the highest total yield, i.e 71.54% (db). Furthermore, the highest anthocyanin concentration and yield were obtained in the extracts using combination of water and ethanol at 270>C i.e. 10 007.03 mg/L (db) and 2.78% (db), respectively. At low pH, the pigment extracts sowed high stability; and gradually decreased and lost color when the pH was increased. The greatest color intensity (red) was obtained at pHs values less than 3.5. The anthocyanins were relatively stable during heating temperature of 40 and 600C in which more than 80% of pigment could be maintained for 4 hour of heating. Heating at high temperatures (80 and 1000C) decreased the color stability more than 80%. Presence of oxidator H2O2 reduced the stability up to 73.52%. The UV and flouresecent light exposure for 7 days also reduced the stability by 11.47% and 10.62%, respectively. Key words: Anthocyanins, Jambolan skin, Extraction, pigment stability

Abstract

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.
