Introduction — Why Oil Quality 
Monitoring Matters
Repeated heating of frying oil leads to oxidation, polymerization, and 
hydrolysis. These processes generate food-borne toxins that 
compromise consumer health and food quality.
 Using a cooking oil test kit or digital cooking oil tester enables real-
time detection of oil degradation before it reaches toxic levels.
Key Benefits:
• Ensures frying oil safety and freshness
• Prevents formation of harmful compounds
• Supports food industry compliance and HACCP programs
Understanding Oil Degradation
Causes of Oil Breakdown:
• Continuous exposure to heat and moisture
• Reaction with oxygen and food residues
• Formation of total polar materials (TPM) indicating chemical 
deterioration
Monitoring Tools:
• Cooking oil testing kit and tpm oil tester detect polar compounds 
and oxidation levels accurately.

TPM – The Key 
Indicator of Oil Health
What is TPM (Total Polar 
Materials)?
• TPM measures polar compounds 
produced during oil degradation.
• It is the most reliable indicator of 
frying oil quality.
Industry Standards:
• Europe: TPM ≤ 24–27%
• India (FSSAI): TPM ≤ 25–30%
Measured by:
 TPM oil tester, digital cooking oil tester, 
or cooking oil testing kit for fast and 
accurate readings.
Working Principle of TPM Oil 
Testers
How It Works:
• Sensor Probe inserted into hot oil.
• Dielectric constant changes detected as polar 
compounds increase.
• Device displays TPM % and temperature.
• Traffic light indicator shows Green (Good), Yellow (Replace 
Soon), Red (Discard).
Examples:
• Digital cooking oil tester with automatic calibration
• TPM cooking oil tester with integrated temperature 
correction

Advantages of Oil Quality 
Testing
• Accurate oil quality testing with instant TPM readings.
• Prevents overuse of oil and formation of food-borne toxins.
• Reduces unnecessary oil wastage and costs.
• Ensures consistent flavor and product quality in fried foods.
• Compliance with international food safety standards.
Tools: frying oil quality tester, tpm oil tester, digital cooking oil tester.
Real-Time Oil Monitoring 
and Toxin Reduction
Research shows that TPM values above 25% directly correlate 
with toxic aldehyde formation.
 Using a TPM cooking oil tester keeps TPM levels below 20%, 
reducing harmful compound buildup by up to 70%.

Case Study — TPM Monitoring 
in Commercial Frying
Scenario:
 A fast-food chain faced inconsistent food taste and customer complaints.
 Action: Installed digital cooking oil tester to check oil every 3 hours.
 Results:
• TPM stabilized below 23%.
• 30% reduction in oil wastage.
• Significant drop in acrylamide concentration in fried foods.
Calibration & Maintenance of 
Testers
Calibration Steps:
• Verify sensor accuracy using reference oils provided in cooking oil 
testing kit.
• Ensure temperature probe calibration every 3 months.
• Clean probe after each measurement to maintain accuracy.
Maintenance:
• Store digital cooking oil tester in dry condition.
• Avoid submerging handle beyond sensor line.
• Perform periodic firmware updates if applicable.
