Measuring Peroxide Value (PV) in Meat Meals

Updated: 1 day ago

Peroxide Value is the measure of primary oxidation, a key quality control parameter in many ingredients and food products, including pet food. Currently Peroxide Value is the parameter used to measure oxidation levels in meat meals to determine if incoming rendered meals are accepted or rejected. 


Although peroxide value is a key parameter, there are no standardizations in place when it comes to testing it in meat meals. The American Oil Chemist Society (AOCS) has official methods for testing fats and oils, but no specifications on how to extract the fat from meat meals to then test on the AOCS Official Method Cd 8-53.


Current extraction methods used are timely, require specialty equipment, and fume hoods. When loads of product are coming in and need to be determined wether to be accepted or not, time is critical. The CDR FoodLab® analyzer allows you to test peroxide value in meat meals within 15 minutes.


The CDR FoodLab® is a pre-calibrated, thermostated analyzer which pair solid-state light emitting diodes (LED) with a user friendly interface to get accurate and reliable results in minutes for food and beverages.

Overview of how the CDR FoodLab® Works

The pre-set calibrations for fats and oils on the CDR FoodLab® were developed in correlation to the AOCS official methods for Free Fatty Acid (FFA), Peroxide Value, and p-Anisidine Value (AnV). Each test has a specific test reagent which come in pre-filled, disposable cuvettes. The analyzer walks the user through how to perform each test, specifying when to take blank readings, how much sample to add, and when to take the final sample readings. With much of the prep and tedious work eliminated, the FoodLab is not only a quick method, but one that helps reduce the chances of user error as well.


The CDR FoodLab and its accompanying test kit for peroxide value utilizes the fact that R-O-O-R peroxides oxidize Fe2+ ions. The Fe3+ ions resulting from oxidation are grouped and form a red complex. Its colorimetric intensity, measured at 505nm, is directly proportional to the concentration of peroxides in the sample. Results are expressed as meqO2/Kg.





For meat meals, the peroxide value can be obtained within 15 minutes and doesn't require skilled technicians or fume hoods to run allowing both renderers and pet food producers to test peroxide value of their meat meals quickly, while maintaining accuracy.

The CDR FoodLab® is also able to test a variety of products in addition to meat meals such as fats/oils and raw meat! Learn more about all the products and tests the CDR FoodLab® is able to do here!
