Monitoring and pollution analysis of aflatoxins in dried chili and chili powder from the cities of Shandong Province
Objective To evaluate the exposure levels and health risks of aflatoxins(AFT)in dried chili and chili powder sold in Shandong Province.Methods AFT in chili and chili powder samples were determined using liquid chromatography-triple quadrupole mass spectrometry,and aflatoxin exposure was calculated using the point evaluation method.Results The detection rate of AFTB1 was the highest in the 120 samples of dried chili and chili powder investigated,at 21.7％(26/120).The proportion of samples exceeding the national standard limit was 8.3％(10/120);the qualification rate was 91.7％(110/120).The detection rate of AFTB2 was 19.2％(23/120),that of AFTG1 was 5.0％(6/120),and that of AFTG2was 0.8％(1/120).The detection rate of AFT in chili powder was significantly higher than that of dry chili samples(P＜0.05).Daily dietary exposure to AFTB1 accounted for 74.1％of the total daily dietary exposure to AFT.The incidence of liver cancer caused by dietary exposure to AFTB1 was 0.001 09/100 000 people.Conclusion Relevant regulatory departments may strengthen the monitoring of aflatoxin pollution in the storage link of chili products,formulate targeted measures according to the temperatures and humidities in each region,maximize the control of aflatoxin pollution,and protect human health.
