BDF (Biodiesel Fuel) is the mainstream as a method for recycling waste food oil. However, since there are many concerns that by-products are generated during the generation process and these are treated as wastes, their use is decreasing. Thus, this study proposes a regeneration method of SVO (Straight Vegetable Oil) fuel by UFB (Ultrafine Bubble) water without transesterification. Therefore, water emulsified fuel (W/O) was used as a fuel reforming means, and the mixed water was changed to tap water, pure water and UFB water, and cause to separate. After that, the supernatant was collected and the peak was detected by a Gas Chromatograph. As a result, when UFB water was used, the reduction of the hydrocarbon peak was the largest. This indicates that radicals are strongly related to the Nano number density in UFB water. The radicals in the UFB water act to reduce the hydrocarbons in the fuel, which will also help reduce the specific odor.
