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.

Abstract

Fruit leather is a fruit product that has been destroyed and then dried using an oven, so as to form a thin sheet that can be rolled. Fruit leather is generally a thin sheet with a thickness of 2-3 mm, 10-20% water content, plastis texture, was a consistency and a specific taste according to the type of fruit used. Ambon banana has a low pectin content that requires a gel-forming agent to produce the desired texture. One of the commonly used gelling materials is carrageenan. Carrageenan is one of the seaweed derived hydrocolloids that have the ability to form gel and can improved the texture of the product. Carrageenan in gel form must have a dehydrating compound. The common dehydrating agent is sugar. Sugar is a material that can attract water molecules that bind to carrageenan molecules, so that sugars can make a solid gel. The purpose of the study to determine the effect of additional sugar and carrageenan concentration on physical, chemical, and sensory characteristics of fruit leather of Ambon banana and to determine the amount of additional of sugar and carrageenan concentration according to sensory data to produce fruit leather with good sensory characteristics. This study used Completely Randomized Design (RAL) consisting of two factors and three replications. The first factor is the percentage of sugar consisting of 5%, 10%, and 15%. The second factor is the percentage of carrageenan consisting of 0.3%, 0.6%, and 0.9%. Tests carried out include physical characteristics (lighness, texture, tensile strength, and elongation), chemical characteristics (moisture content and ash content), as well as sensory characteristics (color, taste, aroma, texture and overall). The data obtained is processed using a fingerprint analysis analysis of variance using Minitab program V.1.7. If there is a significant difference or influence, then a tukey test on test level α ≤ 5% is used. The result of this research showed that the production of fruit leather of banana Ambon with the concentration of sugar and carrageenan added has a significantly characteristic sensory taste and texture, while no significant effect on the sensory characteristics of color, aroma, overall, physical characteristics (lightness, texture, elongation and tensile strength) and chemical characteristics (ash and water content). Determination of the best treatment in this study was found in A2B1 treatment using 10% sugar concentration and 0.3% carrageenan with a very liking assessment as follows 3% color; aroma 13%; 17% texture; 13% taste; and overall 13% with a total value of 59%.

Abstract

Indonesian is the greatest consumer of rice in the world. Their dependence on rice would bother national food security. The availability of artificial rice made from local materials is expected to overcome food security problem. Cassava and corn flour with glutinous rice flour addition as binding agent expected could produce good properties of artificial rice. This research used Modified Cassava Flour (MOCAF) to replace cassava flour. The experiment divided two levels and every level used factorial design with one factor. There were two levels which glutinous rice flour addition was factor in the first level and MOCAF and corn flour composition was factor in the second level. The best values of physical characteristic in the first level are 0% of glutinous rice flour addition with swelling power 94,16%, rehydrating power 73,73%, lightness 84,59, and chrome 28,14, also 20% of glutinous rice flour addition with dispersed material value 5,60%. Whereas, the best sensory evaluation is 0% of glutinous rice flour with whole hedonic score 4,02. The glutinous rice flour addition would reduce the presentage of dispersed material and reduce score of sensory evaluation. In the second level, the best values of swelling power is 118,57%at 40% of MOCAF, dispersed material is 3,60%at 100% of MOCAF. Whereas the best value of rehydrating power is 77,43% at 0% of MOCAF, lightness 87,16%, and chrome 27,24. The best value of sensory evaluation is 0% of MOCAF with score 4,68.

Abstract

Robusta coffee is widely cultivated in Indonesia, and it is often processed into ground coffee. In this study, coffee jelly candy was made for product diversification of coffee. In this case, gel forming agents and sugar are needed to build jelly candy texture, aroma, and taste. The aim of this research was to study the characteristics of coffee jelly candy as affected by sucrose concentration and the ratio of carrageenan to gelatin. A completely randomized design using two factors (sucrose concentration of 40% and 60%; and gelatin to carrageenan ratio of 25:75, 50:50, and 75:25 w/w) was employed. The result showed that sucrose concentrations and gelatin to carrageenan ratio significantly (α > 5%) affected texture, color, moisture content, ash content, and organoleptic parameters (preference towards color, texture, taste, and overall). However, sucrose concentration and the ratio of gelatin to carrageenan not significantly (α < 0,05%) affect antioxidant activity and polyphenol concentration. The effectiveness test showed that coffee jelly candy with 40% sucrose concentration and the ratio of gelatin:carrageenan 50:50 had the highest score with L (lightness) value of 46.79, hardness of 54.53 g/mm, moisture content of 19.26%, ash content of 1.36%, antioxidant activity of 26.63%, total polyphenol of 0.46 mg GAE/mL, preference towards color of 5.60 (rather like), preferences towards aroma of 5.83 (rather like), preferences towards taste of 5.10 (rather like), preferences towards texture of 5.13 (rather like), and overall preference of 5.57 (rather like).
