Abstract

[ENGLISH] Gembolo bulbs were an inferior crop which development has not been optimal. Gembolo bulbs rich in bioactive components such as glucomannan which were a water-soluble dietary fiber because it can absorb 200 times its weight of water. Brownies is a very popular food and flour composites research gembolo on making brownies has never been done, so the presence of composite flour in making gembolo brownies expected to improve the quality and flavor of brownies as a product that safe and good for consumers. The purpose of this study was to determine the influence of the type and percentage of composite gembolo flour physical chemical properties and organoleptic brownies generated. Parameters measured were ash content, moisture content, protein content, fat content, carbohydrate content, overrun, texture, baking loss, stanleness, sliced appearance and WHC. Data were analyzed by ANOVA. The best treatment of compsite treatment is A2B2 treatment (composite flour soaking gembolo 5% citric acid for 24 hours at 20%). Brownies of treatment had 0.68% ash content, water content of 16.83%, 5.15% protein, 23.78% fat content, carbohydrate content of 53.57%, 39.76% flower power, texture 77, 67%, baking loss 5.02%, and 33.96% WHC.

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

Tomato sauce is one of the diversification of tomato products that could increase the added value and shelf life of tomatoes. Sauce made from tomato has a high water content (94 %) resulting a watery sauce product. The purpose of this study was to determine the effect of crude extract Water Soluble Polysaccharide (WSP) from durian seeds on physical, chemical, and organoleptic as characteristics oftomato sauce. The use of crude extract WSP from durian seeds is expected to increase the viscosity of the sauce. The experimental design used in this study was a non factorial randomized complete block design with three replications. Parameters measured were viscosity, color (Hue and Chroma), total dissolved solids, pH, vitamin C, and organoleptic (panelist preferences) in addition to the effectiveness test to determine the best treatment. The results show that the tomato sauce composition significantly affect the viscosity, pH, color intensity, and total dissolved solids, while no significant effect on the angle of color and vitamin C of tomato sauce. The effectiveness test showed that the panelists preferred the P4 tomato sauce (use crude extract WSP from seeds fruit of durian 0.8 %) with fondness value  color of 2.68; aroma of 3.08; flavor of 3.48; viscosity of 3.44; overall liking of 3.56. The value of viscosity, hue, chroma, total dissolved solids, pH, vitamin C were 39.64 centipoise; 38,34°; 20.16; 35° Brix; 4.92; and 4.95 mg/g, respectively. ABSTRAKSaos tomat merupakan salah satu diversifikasi produk olahan buah tomat yang dapat meningkatkan nilai tambah dan umur simpan buah tomat.
