| Abstract: |
| To improve the efficiency of removing aflatoxin B1 (AFB1) from peanut oil by histidine modified montmorillonite(His-MMT), response surface methodology was used to optimize the removal conditions of AFB1 from peanut oil by His-MMT based on single factor experiment, and the quality change of peanut oil before and after adsorption was studied. The results showed that the optimal conditions for AFB1 removal were obtained as follows: dosage of His-MMT 0.17%, adsorption temperature 110 ℃ and adsorption time 22 min. Under these conditions, the AFB1 content in peanut oil decreased from (58.26±0.48) μg/kg to (1.05±007) μg/kg, and the removal rate was (98.20±011)%. After adsorption, the red value of peanut oil decreased from 7.0 to 5.0, the acid value decreased from (0.90±0.02) mgKOH/g to (086±0.01) mgKOH/g, and the retention rates of total tocopherol and total sterol were 8585% and 9726%, respectively. In conclusion, His-MMT can not only efficiently remove AFB1 from peanut oil, but also has little effect on the quality of peanut oil. His-MMT has great application potential in the refining of peanut oil. |
