Six new site calculators have been added.

Three are concerned with determining holding tube length, average holding time and Reynolds number:

 Calculator for determining Reynolds number
 Calculator for determining average holding time in a pasteurizer or UHT holding tube
 Calculator for determining holding tube length in pasteurizing and UHT plant

Following feedback from users of data loggers a unique highly flexible F value calculator designed to work with thousands of pasted values of time -temperatures has been added. This calculator allows users, for perhaps the first time, to compare F values obtained by numerical integration using the industry standard method, the trapezoid rule with the more accurate Simpson's 1/3 and 3/8 rules:

 • Calculator for determining the lethality (F, value) of a thermal process using the trapezoid and Simpson's rules. 

A calculator for predicting the concentration of HMF, lactulose and furosine in heated milks (whole, semi-skim and skimmed milk) that also calculates the F0, B* and C* values and the destruction of thiamine has been added.  The calculator has been designed to work with thousands of pasted values of time -temperatures. The values are integrated using the industry standard method, the trapezoid rule, and are compared with the more accurate method of numerical integration, Simpson's 1/3 and 3/8 rules:

A generic F calculator for UHT and similar high temperature processes has been added. The calculator has been designed to work with thousands of pasted values of time-temperatures. The values are integrated using the industry standard method, the trapezoid rule, and are compared with the more accurate method of numerical integration, Simpson's 1/3 and 3/8 rules

• Calculator for determining the lethality (F, B* values) and chemical changes (C* value) for UHT processes using the trapezoid and Simpson's rules. Applicable to all UHT processes and designed to take thousands of pasted values.
