Discrimination of moldy peanuts with reference to aflatoxin using FTIR-ATR system

Discrimination of moldy peanuts with reference to aflatoxin using FTIR-ATR system

This study demonstrated the potential use of Fourier transform infrared spectroscopy, coupled with attenuated total reflectance unit (FTIR-ATR) for determination of aflatoxigenic and non-aflatoxigenic strains of Aspergillus flavus and Aspergillus parasiticus invasion in peanuts. Threshold mold densi...

Zusammenfassung:This study demonstrated the potential use of Fourier transform infrared spectroscopy, coupled with attenuated total reflectance unit (FTIR-ATR) for determination of aflatoxigenic and non-aflatoxigenic strains of Aspergillus flavus and Aspergillus parasiticus invasion in peanuts. Threshold mold density on peanut paste samples was 2.7 Log CFU/g peanut corresponding to legislative limiting aflatoxin (AF) level of 20 ppb. Classification was performed to separate the “Acceptable” stream (AF ≤ 20 ppb) from so called “Moldy” (20
