| Abstract: |
| The potato chips was repeatedly fried by fresh refined rapeseed oil. The acid value，peroxide value，viscosity and content of polar compounds of the frying oil were determined termly. Intragastric administration experiment on mice was carried out with low，medium and high dosages of deep fried oil respectively and the intragastric administration of fresh refined rapeseed oil was used as the negative control group. After 4 weeks，the effect of deep fried oil on the important organs of mice was studied. The results showed that the acid value，peroxide value，viscosity and content of polar compounds of fresh refined rapeseed oil after frying for 60 times (3 d) increased sharply，which meant the rancidity of the oil. The liver coefficient and AST level of liver function of the mice in high dosage group were significantly higher than the mice in negative control group. Liver pathological section study showed that liver cell injury occurred in different degrees to the mice in medium and high dosage groups，and higher intake of deep fried oil led to heavier injury. |
