Total polar materials (TPM) % is mainly used in Europe as an indicator of cooking oil degradation. TPM is a value that expresses the amount of degraded substances (excluding non-polar materials), such as decomposed substances and polymers, calculated primarily from oils and fats (triglycerides).(see route 1 in the second picture) In addition to TPM, acid value (AV) is also an indicator used to express cooking oil quality and freshness. It is primarily used in other countries such as Japan and America. AV is a value that expresses the proportionate amount of free fatty acids within oil.(see route 2 in the second picture). Values will vary depending on the region and sample.
The DOM-24 is capable of switching between both TPM and AV values for measurement. Please use the scale most suitable to your application.
Introducing a frying oil monitor that can be used to periodically check and monitor the quality of oil.
This instrument is capable of measuring both TPM (Total Polar Materials), a standard used in Europe as an indicator of the overall quality of frying oil, as well as AV (Acid Value), which indicates changes in cooking oil properties.
