H. Boudra et al., THERMOSTABILITY OF OCHRATOXIN A IN WHEAT UNDER 2 MOISTURE CONDITIONS, Applied and environmental microbiology, 61(3), 1995, pp. 1156-1158
The decomposition of ochratoxin A (OTA) was examined, under different
temperature and moisture conditions, The calculated half-lives, corres
ponding to 50% values, were 707, 201, 12, and 6 min, respectively, at
100, 150, 200, and 250 degrees C for dry wheat and 145, 64 and 19 min,
respectively, at 100, 150, and 200 degrees C for wheat heated under w
et conditions. The presence of water (50%) increased the decomposition
of OTA at 100 and 150 degrees C; the opposite was observed at 200 deg
rees C. Complete destruction of OTA within the limits of this study (1
00 to 250 degrees C) was not obtained.
