Occurrence of aflatoxin B1 in natural products
The media claims for the consumption of natural resource-based food have gradually increased in both developing and developed countries. The interest in the safety of these products is partially due to the possible presence of toxigenic fungi acting as mycotoxin producers, such as aflatoxins produced during the secondary metabolism of Aspergillus flavus, A. parasiticus and A. nomius. Aflatoxins...
متن کاملAflatoxin B1 Residues in Eggs and Flesh of Laying Hens Fed Aflatoxin B1 Contaminated Diet
Aflatoxin B1(AFB1) and total Aflatoxins (AFT) contaminated feed effect on aflatoxins residue level in eggs, muscles (breast, leg), organs (liver, kidney, gizzard) and excreted aflatoxins in chicken litter of layer hens were monitored. Laying hens were on four levels of aflatoxins for 6 weeks and monitored weekly for the change in both AFB1 and AFT levels. Pronouncedly, the AFB1 and AFT were det...
متن کاملOptimization of Aflatoxin B1 Aptasensing
Combination of aptamers with DNAzymes attracted intense attention for development of DNA-based biosensors for detection of mycotoxins. In the present study a combination of aflatoxin B1 specific aptamer and HRP- (horseradish peroxidase-) mimicking DNAzyme was optimized for detecting aflatoxin B1. Detecting approach is based on the binding affinity of aflatoxin B1 to its specific aptamer and con...
متن کاملAflatoxin B1 dihydrodiol antibody: production and specificity.
A specific antibody for 2,3-dihydro-2,3-dihydroxyaflatoxin B1 (AFB1-diol) was prepared, and its reactivity was characterized for the major aflatoxin (AF) B1 (AFB1) metabolites. Reductive alkylation was used to conjugate AFB1-diol to ethylenediamine-modified bovine serum albumin (EDA-BSA) and horseradish peroxidase for use as an immunogen and an enzyme-linked immunosorbent assay (ELISA) marker, ...
متن کاملIn vitro ability of beer fermentation residue and yeast-based products to bind aflatoxin B1
This study aimed to verify the in vitro ability of beer fermentation residue (BFR) containing Saccharomyces cerevisiae cells and five commercial products that differed in the viability and integrity of S. cerevisiae cells to remove aflatoxin B1 (AFB1) from a citrate-phosphate buffer solution (CPBS). BFR was collected at a microbrewery and prepared by drying and milling. The commercial yeast-bas...
