Hello,

 

Could anyone give me advice on the best way of carrying out a microwave cook validation?

Should I be basing it off one wattage or do it over 2 to 3 different wattages?

If i do it off 2 to 3 different wattages can I then declare the shortest cook time as long as the cook kill temperature is reached?

 

Thanks,

 

Natalie.

what is the product type and is this instruction for consumers or for food service?

 

I had a product that was a re-heat, it was pre-cooked. I looked at similar products in the frozen food section and found the most common wattage recommendation. We used that as our base and the temp we needed it reheated to for quality was higher than 165.

Hello quality elf,

 

IMO, you can based you cook validation on wattage alone. Core temp of the product must be measured as evidence.

hi Natalie,

 

I have seen official methodologies published for this query. IIRC they were not exactly simple.

 

I suggest you check a little, eg FSA.

Hello,

 

The product is baby potatoes that will be sold raw and microwaved by consumer before consumption. 

I am currently testing in a 800w microwave and testing different cook times. For each cook time i am recording 5 results of core temperatures of the baby potato. I am just wanting to know if this is enough to prove due diligence by proving that an acceptable core temperature is reached.

 

Thanks,

Hi Natalie,

 

From distant memory, you also need to profile the temperature variation within the unit so as to determine the slowest heating point. I think this was the cause of certain micro. problems with the original units.

PS - more suggestions are available if you google - "validation microwave ovens"
