Do acid value strips validated against TPM count?

Dears

We have a TPM testing device for deep-frying oil, and it was validated in the past.
We purchased acid value test strips a week ago.

I brought three types of oil: fresh oil, degraded oil, and highly degraded oil.
I measured the TPM and acid value for each one and determined the acceptable and unacceptable acid value limits based on the TPM readings.
Does this count as a validation process?

When you say "device... validated in the past" do you mean calibration, assay proficiency testing, comparative analysis, etc?

 

This method sounds more like a process verification activity rather than a validation of the process.

 

How are you determining your acceptable/unacceptable limits? is this industry standard or other scientific published data?

 

I would be more inclined to revalidate the process independently with a 3rd party experienced in these analytics based on your finished product profile, cooking times and temps, cooking process, oil types, ingredients, etc. 

 

 

We have a deep-frying step in our company for food products such as potatoes, which is classified as an OPRP, and the hazard is FFA. The oil is monitored using a TPM device, and a validation was previously conducted to confirm that the deep-frying step controls the hazard of FFA.

We now want to use a new device that measures the Acid Value (AV) of the oil. How can we perform validation, and is it necessary to conduct a validation study?

I'm not all that familiar with FSSC, however if you are establishing a quality or critical limit with the addition of the AV quick test then it is a best practice to validate the controls in place. 

 

The manufacturer of the test kit would most likely already have plenty of data to support their own claims.
