How is Mean Kinetic Temperature Calculated? Technically speaking, MKT is an expression of cumulative thermal stress experienced by a product at varying temperatures during storage and distribution.Įvidence The Weatherman Lp Zip there. Consider the following example: EXAMPLE: A dozen eggs sat: In a 20☌ room for 2 hours In a 2☌ refrigerator for 4 hours And on a 25☌ loading dock for 1 hour Using MKT we can calculate that the temperature profile of the eggs was “thermally equivalent” to storing them at 10.096☌ for 7 hours. Mean Kinetic Temperature (MKT) is a simplified way of expressing the overall effect of temperature fluctuations during storage or shipment of perishable goods.
