Abstract

A research on dietary exposure assessment for aflatoxin B (AFB1) fromprocessed peanutproducts in Municipality of Bogor was carried out. The objectives of this study were todetermine the contents of AFB1 in processed peanut products at retail levels, and to obtaininformation whether there is a risk to public health caused by the consumption of processedpeanut products contaminated by AFB1. Survey of processed peanut product consumptionwas carried out by interviewing each respondent using a questionnaire of weekly processedpeanut product consumption. Sampling of processed peanut products was conducted at thelocations where the respondents obtained processed peanut products. The number of roastedpeanuts with skin pods, flour-coated peanuts and or sauces samples was 33,respectively, while the number of and sauces samples was 18 and 12, respectively.The total number of processed peanut product sampleswas 129.AFB1contentwas determinedusingThin LayerChromatographymethod.Estimation of the dietary exposure assessmentwasdetermined using the actual survey data consisting of AFB1 content, consumption data andbody weight. The highest contaminated sample percentage and mean of AFB1 content wasfound in roasted peanuts with skin pods i.e. 42% of 33 samples and 43.2 μg/kg, respectively,followed by flour-coated peanuts (30% of 33 samples and 34.3 μg/kg), and or(21%of 33 samples and 17.1 μg/kg).Mean of estimated dietary exposure for AFB1 found inchildren was 15.2 ng kg bw day and 95 percentile exposure was 38.9 ng kg bw day , while inadults 9.0 ng kg bw day and 95 percentile exposure was 27.0 ng kg bw day . The excesscancer risk of AFB1 exposure in Bogor fromthis study on children and adults was calculated as193 and 115 cancers/year, respectively-1 -1 th -1 -1-1 -1 th -1 -1pecel gado-gadosiomay sataipecel gado-gado1.

Abstract

The objectives of this study were to collect informations on the method of postharvesthandling of sorghum and to investigate the moisture contents, insects infestation, fungalinfection, and aflatoxin B contents of stored sorghum grains collected from various stagesof the delivery chain in Demak and Wonogiri regencies, Central Java. In Demak regencysorghum cultivation was monoculture, variety cultivated was UPC-S1. In Wonogiri regencysorghum cultivation was intercropping with secondary crop and cassava. Sorghum varietiescultivated were Kawali, Numbu, ZH30, Mandau and Hibrida hybrids. There was a differencebetween the method of postharvest handling of sorghum at farmer and collector levels inDemak andWonogiri regencies. In general the method of postharvest handling of sorghum inDemak regency was more appropriate and more advance compared to that in Wonogiriregency. The moisture contents of sorghum at farmer as well as at collector level in Demakregency (13.0%) and Wonogiri regency (12.9%) were still lower that that of normal (safe)moisture content of sorghum. The number of insect species associated with sorghum invarious distribution level in Demak andWonogiri regencies was 10 and 17 species, respectively.The dominant insects species were and . The number offungal species found in sorghum at various distribution level in Demak andWonogiri regencieswas 23 species, respectively. In general, the dominant fungal species were ,and . In Demak regency aflatoxin B contents of sorghum atfarmer and collector levels were 22.50 and 15.45 ppb, respectively, while in Wonogiri regency2.27 and 10.28 ppb, respectively.insects, fungi, aflatoxin B , stored sorghum, Demak and Wonogiri regencies,Central Java
