In our study, as it can be observed
in Table 1, this range of moisture content was achieved during
convective drying of Stevia leaves at temperatures between 30
and 40 °C. Moisture content may be reduced to a value near to
1 g/100 g d.m. at a drying temperature of 80 °C, which
brought water activity down to 0.04 ± 0.01
