| Research Abstract |
1.The application to foods making of Tobiko (fly powder) generated by Konnyaku (Amorphophallus konjac) production was studied. Well-refined Tobiko was obtained with a 25% ethyl alcohol solution, temperature at 30℃ and ultrasonication for 15 min. The odor characteristics and brown color of Tobiko material A were both decreased by the refinement with ultrasonication. Comparatively large amounts of components such as protein, dietary fiber and minerals were contained in this material Scanning electron microscopic observations of Tobiko refined by ultrasonication showed dispersed particles, indicating Tobiko material A to be a potential new food material
2.The usage of Tobiko as a food material was tested by preparing bread, sponge cake, rusk and biscuits, their physical properties, palatability and preservation were studied Material A could be substituted for flour by up 7% in bread, 7.5% in sponge cake or rusk and 10% in biscuits without any effect on their textural properties and palatability. Moreover, it showed favorable results in preservation test. The addition of 7.5% of material A was the most appropriate as a binder of soba noodles, its soba noodles tended not to have a high breaking point and elasticity, and the elongation was restrained. In addition, the higher antibacterial activity is presumed to have been due to material A. The addition of Tobiko thus enhanced the quality of bread, sponge cake, rusk, biscuits and soba noodle.
