Abstract
This study aimed to develop a value-added product from Colocasia leaves through the implementation of the vacuum frying technology. In this study fresh Colocasia leafy rolls were made by applying smooth paste of gram flour, rice flour and spices, 4-5 leaves were tightly rolled, steamed, cut into slices and vacuum fried at 9 kpa and temperature 1000C, for 20 minutes. The vacuum fried and atmospherically fried Colocasia leaves rolls were subjected to sensory evaluation for the quality attributes in terms of colour, taste, after taste, texture and overall acceptability using the 9-point Hedonic Scale by semi trained panelists. Results of the sensory evaluation suggest that the quality attributes of the vacuum fried Colocasia leaves rolls were liked very much by the panelists, however, significant differences existed in terms of the colour and general acceptability of the product. Chemical analyses of vacuum fried Colocasia leafy rolls showed moisture 0.69%, oil 28%, crude fiber 2.5%, and total phenolic content 733.16 mg GAE/100gm. The texture was analyzed by TA-XT Stable Micro Texture Analyzer. The force required to cut Colocasia leaves roll was found to be 4.22kg. The L*, a*, and b*values of vacuum fried and atmospherically fried Colocasia leafy rolls were 29.38,-1.252, 17.68 and 19.35, 3.62 and 12.25 respectively. The products overall acceptability was found to be 8.5, like very much on the 9-point hedonic scale. Results suggested that vacuum fried Colocasia leafy rolls are highly acceptable.
