Impact of storage environment on respiration, dry matter losses and fumonisin B 1 contamination of stored paddy and brown rice
The objective of this study was to compare the effect of different storage moisture conditions (0.90 and 0.95 water activity, a w ) and temperatures (25, 30 °C) on (1) respiration rates (CO 2 R), (2) dry matter loss (DML) of paddy and brown rice, (3) inoculation of both rice types with Fusarium vert...
