dc.description.abstract | Characterization needs to be done to determine the consistency of product quality. Appropriate methods are needed to characterize jelly drink. This is due to jelly drink is a gel product that is different from other types of gel products in terms of consumption. Jelly drink products consumed by aspirated (flow) and immediately swallowed like drinks. This research used compression extrusion test method because this method uses the principle of emphasis to an existing product extruded under the probe (flow), which is suitable for semisolid material like gel. Raw materials used in this study were jelly powder, carrageenan 0,4% + 0,05% konjac, carrageenan 0,4% + konjac 0,1%, carrageenan 0,4 % + LBG 0,05%, and karaginan 0,4% + 0,1% LBG. The results of characterization by using texture analyser and compression extrusion test method showed that the jelly powder 0,33 % (as control) has gel fracture and firmness values lower than carrageenan 0,4%+konjac 0,05%, carrageenan 0,4%+ konjac 0,1%, and carrageenan 0,4%+LBG 0,1%, and the brittleness and gel strength max, higher than carrageenan 0,4% + konjac 0,05% , and carrageenan 0,4% + LBG 0,1%. Based on sensory test and statistical test were using univariate models and continued test were using Duncan with 95% confidence level, showed that all samples have the brittleness were not significantly different with jelly powder o,33%, except carrageenan 0,4% (without the addition of LBG or konjac), and the firmness of samples carrageenan 0,4% + 0,05% LBG, carrageenan 0,4% + 0,05% konjac, and carrageenan 0,4% + 0,1% LBG was not significantly different with jelly powder 0,33%. Graphically, the addition of konjac with the same concentration with the addition of LBG up to 0,1%, rise in influence gel fracture, gel max strength, and firmness value was higher in carrageenan 0,4%. | en |
