The average moisture binding energy of a textured protein product (TPP) at 8% moisture content (dry basis) is 3200 cal·mol$^{-1}$. If the water activity of the TPP at the above moisture content is 0.30 at $30^{\circ}$C, the water activity of the sample at $45^{\circ}$C is ................ (rounded off to 2 decimal places). Gas constant $R=1.987$ cal·mol$^{-1}$·K$^{-1}$.
Radiation dose required for 8 log reductions:
D₁₀ range = 0.75–1.80 kGy → Dose = 8 × D₁₀ = 6.00–14.40 kGy.
Answer: 6.00 to 14.40 kGy
