Statement 1: Which of the following methods is used to determine process times for products?

Statement 2: Which of the conditions is the above method used in?

Slowest heating-fastest cooling composite data from heat penetration studies will be excess under sanitary conditions

Inoculated pack studies, will be inadequate under poor processing conditions

Statistical evaluation, will be inadequate under poor processing conditions

All of the mentioned, all of the mentioned

Which of the following is required for calculation of process time by Ball’s method?

C and z value of thermal death time curve

Number of degrees which exist between the retort temperature and the maximum temperature

Statement 1: In thermal death time curve, after plotting C/t values from it, C value should be equal to Co value.

Statement 2: When Co value versus process time in minutes is plotted on a linear graph paper, a straight line is obtained.
