How cooking oil testing works

Testo’s 270 allows you to determine within seconds whether cooking oil needs changing. To do so, it measures the ‘Total Polar Material’ (TPM) content in the oil, which is a sure indicator of its quality. It will then provide you with a reading and based on the colour of the screen display you will know the current state of the oil.

Using the 270 couldn’t be simpler, just insert the tip into the oil and you will get a reading. Depending on the screen colour you will know if the oil needs changing or not. Green means the oil is perfectly fine, amber is when it’s on the brink, and red means the oil needs changing immediately.


  • Green =                TPM content is good.
  • Amber =              TPM value will need changing soon.
  • Red =                   TPM value has exceeded safe amount.

The Dangers of using old, used cooking oil

There are a number of risks associated with a company using cooking oil that is past its best. A recent Testo study looked at the Frying Oil Quality Curve, which explains each step of the process.

As the oil begins to get older, the fried food becomes darker and could feature spotty surfaces. In addition, the fried shell is less crisp and the food absorbs much more oil than usual. This can leave a bitter, unpleasant taste and is also unhealthy because of a higher content of saturated fats.

As the cooking oil continues to deteriorate the fried product will start to become hard, oily and the food inside might not even cook properly. This can then cause problems from a food safety point of view. It can also produce a burnt flavour and give off a pungent smell.

Essentially, the more times cooking oil is used and the longer it’s left, the poorer the quality it will be and the lower the standard of the fried product.


Make sure you're using top quality oil and save money at the same time

Extensive practical tests have proved that regular measurement with the Testo 270 reduces the overall consumption of cooking oil by up to 20%. Therefore it’s not just productivity that will be improved with a Testo 270, but also costs can be significantly reduced.
