摘要：Nanofibril is a bio material in the form of fibrils and nano-sized. These fibrils can be made from protein; one of them is soy protein isolate (SPI). Nanofibrils can be used in the fields of food and medicine, for example, shells of microcapsules, food thickener, and food texture makers. To utilize this nanofibril need to know the characteristics of nanofibrils. One of the important characteristics of nanofibrils is the diameter and length of nanofibrils. Based on the shape of the fibrils that can be taken from the image with TEM (Transmission Electron Microscopy) visible irregular curved fibrils. Therefore we need a measurement method that can measure the length of the nanofibrils. One such method is to trace the image of the fibril and convert it to a certain scale. Methods that can be used to trace and measure the length of the curve are using the GDG Measure It to DRAW X4, X5, X6 which is nested in Corel DRAW X4 (Evaluation Version). Based on the results of calibration and trials show this method can be used to measure the length of nanofibrils with an error of about 0.17%.
