Quality testing is one of the most critical stages in fish oil manufacturing. High-quality Omega-3 fish oil must meet strict quality standards before it can be used in dietary supplements, pharmaceuticals, and functional foods.
To evaluate the freshness, stability, and overall quality of fish oil, manufacturers perform several laboratory tests. Among the most important are Acid Value (AV), Peroxide Value (PV), Anisidine Value (AnV), and TOTOX (Total Oxidation Value). Together, these parameters help assess whether fish oil has been properly processed and stored.
Why Is Fish Oil Quality Testing Important?
Fish oil is naturally rich in Omega-3 fatty acids, but these beneficial oils are also sensitive to oxygen, heat, and light. Without proper manufacturing, purification, and storage, oxidation can occur, reducing product quality.
Regular laboratory testing helps manufacturers:
- Monitor product freshness
- Evaluate oxidation levels
- Verify product consistency
- Support quality assurance
- Meet customer specifications
What Is Acid Value (AV)?
Acid Value measures the amount of free fatty acids (FFA) present in fish oil.
Free fatty acids can increase when oil is exposed to moisture, improper handling, or prolonged storage.
Why is AV important?
A lower Acid Value generally indicates better-quality fish oil and effective processing.
Factors affecting AV
- Quality of raw material
- Storage conditions
- Processing methods
- Time before refining
Manufacturers routinely monitor AV throughout production to maintain consistent quality.
What Is Peroxide Value (PV)?
Peroxide Value measures the amount of primary oxidation products formed in fish oil.
Oxidation begins when oxygen reacts with the fatty acids in fish oil, producing peroxides.
Why is PV important?
A low Peroxide Value indicates fresher oil with minimal oxidation.
Higher PV values may suggest:
- Extended exposure to oxygen
- Improper storage
- Delayed processing
- Excessive heat exposure
What Is Anisidine Value (AnV)?
Anisidine Value measures secondary oxidation products, particularly aldehydes that form after the initial oxidation stage.
Why is AnV important?
While PV indicates early oxidation, AnV provides information about more advanced oxidation.
Together, PV and AnV give a more complete picture of oil quality.
What Is TOTOX Value?
TOTOX stands for Total Oxidation Value.
It combines both primary and secondary oxidation measurements into a single quality indicator.
The commonly used formula is:
TOTOX = (2 × PV) + AnV
This value helps manufacturers evaluate the overall oxidation status of fish oil.
Other Important Fish Oil Quality Tests
In addition to AV, PV, AnV, and TOTOX, manufacturers often perform:
EPA & DHA Analysis
Measures the concentration of beneficial Omega-3 fatty acids.
Heavy Metal Testing
Checks for contaminants such as:
- Mercury
- Lead
- Cadmium
- Arsenic
Dioxins and PCBs
Advanced testing helps verify that environmental contaminants remain within applicable limits.
Moisture Analysis
Excess moisture can affect product stability.
Microbiological Testing
Confirms the product meets microbiological quality requirements.

Frequently Asked Questions
What does AV mean in fish oil?
AV (Acid Value) measures the level of free fatty acids in fish oil and is an indicator of oil quality.
What is Peroxide Value?
Peroxide Value (PV) measures primary oxidation products formed during the early stages of oxidation.
What does TOTOX indicate?
TOTOX is an overall indicator of oxidation, combining Peroxide Value and Anisidine Value to assess fish oil quality.
Why are oxidation tests important?
They help manufacturers monitor freshness, maintain product quality, and support consistent manufacturing standards.
