A frying oil quality tester is an instrument used to quickly assess the quality of edible oils. It primarily measures the content of Total Polar Materials (TPM/TPC) produced during high-temperature frying, thus determining whether the oil has deteriorated or is no longer suitable for use. Edible oil analyzers are easy to operate, directly displaying oil quality indicators, and are widely used in catering, fast food, food processing, and kitchen safety management to help ensure food safety and oil quality.

What do the TPM/TPC values of a cooking oil tester represent?

TPM (Total Polar Materials) or TPC (Total Polar Compounds) represents the percentage of total polar compounds in the oil. During frying, oils undergo oxidation, decomposition, and polymerization reactions, generating polar compounds. A higher TPM/TPC value indicates greater oil deterioration, with a greater impact on food taste and health risks. Generally, when the value reaches 24–25% or the manufacturer's recommended threshold, the oil should be replaced promptly.

How to use an edible oil detector correctly?

Before use, allow the oil temperature to stabilize (usually within the range specified in the equipment manual). Immerse the probe in the oil to an appropriate depth, avoiding contact with metal parts. Wait for the reading to stabilize before taking the TPM/TPC value. After measurement, clean the probe and store it properly to ensure the long-term accuracy and lifespan of the cooking oil tester. Regularly checking and calibrating the edible oil detector also helps maintain measurement accuracy.
