- Abstract:
- This study was conducted to investigate the natural co-occurrence of multiple toxic fungal and bacterial metabolites in sugarcane grass and juice intended for human consumption in Upper Egypt. Quantification of the target analytes has been done using the "dilute and shoot" approach followed by liquid chromatography-tandem mass spectrometry (LC-MS/MS). A total number of 29 and 33 different metabolites were detected in 21 sugarcane grass and 40 juice samples, respectively, with a trend of concentrations being higher in grass than in juice. Among the regulated mycotoxins, only aflatoxin B-1 (AFB(1)) and aflatoxin G(1) (AFG(1)) were detected. The prevalence of AFB(1) was in 48% of grass samples and in 58% of juice with a maximum concentration of 30.6 mu g/kg and 2.10 mu g/kg, respectively. AFG(1) was detected in 10% of grass samples (7.76 mu g/kg) and 18% of juice samples (34 mu g/kg). Dietary exposure was assessed using a juice frequency questionnaire of adult inhabitants in Assiut City. The assessment revealed different levels of exposure to AFB(1) between males and females in winter and summer seasons. The estimated seasonal exposure ranged from 0.20 to 0.40 ng/kg b.w./day in winter and from 0.38 to 0.90 ng/kg b.w./day in summer.
