Abstract:

Objective To investigate the dietary exposure and risk level of aflatoxin(AFT) and ochratoxin A(OTA) in chili products sold in Hainan Province. Methods High performance liquid chromatography tandem mass spectrometry(HPLC-MS/MS) was used to determine the content of AFT and OTA in chili products,and the pre-treatment was purified using an immunoaffinity column. The point estimation method was employed to calculate the dietary exposure levels of AFTB1 and OTA in chili products consumed by the Hainan population. In accordance with the risk assessment method recommended by the Joint Expert Committee on Food Additives(JECFA),the efficacy of AFTB1 in inducing liver cancer was evaluated. The dietary exposure levels of AFTB1 and OTA in chili products were computed by the margin of exposure(MOE) method,thus obtaining the MOE value. Results A total of 109 samples of chili products were collected. The detection rate of AFB1 was the highest,reaching 44.03%,and the over-standard rate was 2.75%. The detection rate of OTA ranked second,at 22.02%,followed by AFTB2(11.00%),AFTG1(4.59%),and AFTG(20.92%). The dietary exposure levels of AFTB1 and OTA were 0.035 and 0.016 ng/(kg·BW/d),and the MOE values were 11 428 and 906 250 chili praducts sold in Hainan Province. Conclusion There is contamination of AFT and OTA in chili praducts sold in Hainan Province.The MOE values of both were greater than 10 000,indicating that the public health security risk was within a controllable range.
