Food storage temperatures



For every 10 degrees C, shelf life will halve or double (hotter-cooler).

Q10 Rule-of-10 Temperature vs. Shelf Life
The temperature coefficient (Q10) represents the factor by which the rate 
(R) of a reaction increases for every 10-degree rise in temperature (T).
Q10=[R2/R1]^[10/(T2-T1)]
T1: Hypothetical Storage Temperature (C)
T2: Room Temperature Constant (22 C)
R1: Rate Reference of the rated shelf life (# days, weeks, months, years, 
etc.)
R2: Rate to solve for (will be same unit as R1)
Q10: 2 (doubling)
 
Examples
(rounded to nearest decimal)
 
degrees-Celsius
A can of food with a rated shelf life of 1 year (at room temperature 22 
degrees C) will actually reduce to one-half year if stored at 32 degrees 
C.

Formula for the example above:
T1: 32-degree-C storage temperature
T2: 22-degree-C room temperature constant
R1: 1 year rated shelf life
R2: ?
2=[R2/1]^[10/(22-32)]
solve for R2
R2=0.5
 
If we store the same can of food in a cooler environment, the inverse is 
true…
degrees-Celsius
A can of food with a rated shelf life of 1 year (at room temperature 22 
degrees C) will actually increase to 2 years if stored at 12 degrees C.
