Congratulations to my International Journal of Dairy Technology (IJDT) colleagues

Relationship between z-value (Bigelow method) and activation energy (Arrhenius model)

Compare the accuracy of three algorithms for predicting the concentration of lactulose in milk after a defined heat treatment

Details
Created: 28 February 2021

A calculator that enables the concentration of lactulose to be predicted after a single, defined heat treatment using 3-algorithms developed by Browning et at. (2001), Claeys et al. (2003) and Rombaut et al. (2002) has been added to the website. All algorithms use the Arrhenius rate equation but use slightly different values for activation energy (E). Note that a value of E = 122 kJ/mol has been used in the algorithm reported by Browning et at. (2001).

This compliments the calculators in the article "Ultra-high-temperature (UHT) processing of milk. Process lethality, chemical effects and use of temperature-time-integrators (TTIs) to predict heat treatment and over-processing".
