_________ is equal to the reciprocal of the slope of the thermal death time curve.

_________ is equal to the reciprocal of the slope of the thermal death time curve. Correct Answer Z value

Z-value is used in the microbial thermal death time calculations. It is defined as the temperature (in degree) at which a tenfold reduction in D-value is attained. It is equal to the reciprocal of the slope of the thermal death time curve.
