About this document
D Value and N/No Calculations by zabeali is a document available to read on EtoBox.
This document provides two thermal processing examples involving determining the D-value and calculating survivor ratios for microorganisms. The first example calculates the D-value of 27.75 minutes for a spore suspension using thermal resistance data and exponential regression analysis. The second example uses a given D-value of 8.3 minutes at 105°C to calculate the survivor ratio (N/N0) at times of 5, 15, and 20 minutes based on the number of survivors observed at 10 minutes. An Excel spreadsheet is inclu
