Impact of storage environment on respiration, dry matter losses and fumonisin B1 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...
