Crops contaminated with fungal mycotoxins such as aflatoxin B1 (AFB1) are often downgraded or removed from the food chain. This study aimed to evaluate the tolerance and accumulation of AFB1 in two insect species to determine whether they could be used to retain condemned mycotoxin contaminated crops in the food chain. First, instar black soldier fly larvae (Hermetia illucens, BSF) and yellow m...

Aegle marmelos leaves have been used for treatment of various liver aliments from time immemorial. Pre-treatment of A.marmelos leaves crude powder at its therapeutic dose (1000 mg/kg body weight) was carried out to determine the efficacy on aflatoxin B1 (AFB1) (1 mg/kg body weight) induced liver toxicity in rats. The crude powder of A.marmelos was found to be a potent inducer of the phase II de...

Quantitative losses in various biochemical constituents like capsaicin, carotenes, ascorbic acid, polyphenols, mineral matter, sugars (soluble and insoluble), protein and fat were estimated after the successful growth of Aspergillus flavus for 30 days on powdered red pepper. The fungal biomass was measured by ergosterol content and Aflatoxin B1 by HPLC. Amongst the various nutritional constitue...

Experiments were designed to determine the in vivo effects of a single 6-mg/kg dose aflatoxin B1 on rat liver mitochondrial transcription and translation processes. With the use of intact hepatocytes and also a highly active mitoplast system for incorporation, it was observed that both mitochondrial transcription and translation activities are inhibited progressively even after 24 hr of carcino...

BACKGROUND Aflatoxins are serious hazard to poultry industry and human health. Broiler chickens fed on aflatoxin contaminated feed develop various abnormal signs and behavior including less attraction toward feed, abnormal faeces consistency, growth retardation, dirty and ruffled feather, abnormal organs size and weight and blood serum biochemistry. Therefore the study was aimed to detoxify afl...

Background: Aflatoxin B1 is a secondary toxic metabolite produced by several aspergillus species. This study was conducted to determine the presence of aflatoxin in tomato paste samples. Methods: A total of 30 tomato pastes were analyzed for Aflatoxin B1 contamination via HPLC-FLD. Analyte extraction was done by dispersive liquid-liquid microextraction. Results: The limit of detection (LOD) and...

1. Aflatoxin B(1), administered in vivo, inhibits the incorporation of [(14)C]orotic acid in vivo into rat liver nuclei, and also inhibits both Mg(2+)- and Mn(2+)-dependent RNA polymerase activities in nuclei assayed in vitro. 2. Aflatoxin B(1) inhibits the cortisol-induced increase in incorporation of [(14)C]leucine in vivo, but does not affect the control value of this activity. 3. Aflatoxin ...

Materials and methods: Ninety pigs (9.42 ± 0.05 kg) were used in a study with five dietary treatments: an uncontaminated control diet with no additives and four similar diets that were contaminated with 500 ng per g aflatoxin B1 (AB1) and supplemented with no additive, with 0.5% HSCAS, with an antioxidant preparation providing 125 mg per kg of ethoxyquin and 10 mg per kg of TBHQ, or with both H...

The aim of this study was to determine the contamination levels by aflatoxins M1, M2, G1, G2, B1 and B2 Ochratoxin A in 123 infant formula powder samples from metropolitan region Rio de Janeiro, Brazil. sensitive method using a modified Quick Easy Cheap Effective Rugged Safe (QuEChERS) ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) validated for application ...

background and purpose: mycotoxins are secondary fungal metabolites with a very high diversity that are produced by some species of aspergillus which frequently leads to contaminate food and agricultural products. recently, elimination of aflatoxin contamination in food and feed has been considered by scientists worldwide. although, the antibacterial and antifungal effects of vitamins as natura...
