| Abstract: | Based on the national standard method of animal and vegetable fats and oils,the sense indexes,iodine value,refractive index,peroxide value,acid value and electrical conductivity of ‘Gutter Oil＇and edible oil were comparatively analyzed. The analysis results showed that the acid value and electrical conductivity of ‘Gutter Oil＇were significantly increased by comparing with the edible oil,and the acid value and electrical conductivity can be used as identification indexes of ‘Gutter Oil＇. |
