My problem is that, how we can define the z value? from where? is it from retort graph?

Dear ati,

The definition / equation is more or less standard and available in any text book. However the actual value used in practice may be from a specific analysis under controlled conditions but is often via a review of available published, validated, experimentation on the actual (or similar) food matrix / conditions involved.

A text book may be yr quickest answer however you might try this post/ surrounding thread which contain some other general internal forum links and attachments -
