Hi, it such helpful content. Sorry maybe its too late, but I want to ask u about Q10. what if the temperature difference isn't 10 C and still using the general formula without modification? bcs, the journals that Ive seen use the Q10 general formula with changes in temperature (for example) 6 C. is there a certain reason why the formula can still be used? I really need this answer and thank you if youre interested in replying to this comment! :)
Why would you use the difference in temperature as the numerator when the Q10 equation states that the temperature differences should be the denominator?
Is there a chart showing food life vs temperature? I'm making a Peltier fridge and 4°C might be just out of reach so I'm wondering how long various food items can last at 5-10°C
Hi Patrik! I don't think there is. This is because each food item behaves differently than others. But as a rule of thumb, the temperature range of 5 to 60°C is conducive for microbial growth.
thank you so much for this
So amazing. This is extremely essential information for food technologists. Many thanks for sharing!
Glad it was helpful! We aim to share food science to everyone!
Great content. Could you share how you arrive at the Q10 of 1.38 though?
Probably a literature value that was calculated from a shelf-life study
thank you!!
thank you for sharing!
Does this apply to vegetable oils?

I think you're referring to the equation where the exponent is on the other side of the equation.
