Post production aflatoxin contamination in cassava (Manihot esculenta Crantz) in the Philippines
1985
Sajise, C.E.
No aflatoxin was obtained at different stages of maturity (from 7 to 14 months old cassava roots) and at 24 to 48 hrs. of sundrying. During storage, however, trace amounts of aflatoxin B1 were observed in stored cubes but not in stored chips and unprocessed roots. When dried adequately (12.0% moisture content), cassava chips had better keeping qualities than cassava cubes not only because of reduced microbial contamination but also due to the absence of aflatoxin. In the absence of competing fungi fresh cassava roots proved to be a good substrate for the growth of Aspergillus flavus and A. parasiticus but not for aflatoxin production. A fluorescent compound behaving like aflatoxin B1 was observed in samples exhibiting vascular discoloration. The confirmatory test conducted proved these compounds were not aflatoxin
