Description of the peroxide test
Our kit method detects the determination of peroxide values for animal oils and fats, vegetable oils and fats, as well as for flavour and fragrance materials. The peroxide value is a parameter specifying the content of oxygen as peroxide, especially hydro peroxides in a substance. The peroxide value is a measure of the oxidation present.
MenidiMedica method shows a very good correlation with AOCS Official Method Cd 8-53. Furthermore Peroxide Value was determined using Electra m2 Unified Analyzer and the UKAS accredited titration method used by Campden BRI (Campden BRI
Method TES-AC-360). The data for PV using Electra m2 Unified Analyzer was found to be very consistent with good reproducibility across the triplicate runs and the correlation between the two methods is good.
Presentation of the peroxide test
Ref. No: 89010 – 50 tests
R1 – 2.5 mL.
R2a – 1.25 mL.
R2b – 1.25 mL.
R3 – 0.05 mL.
R4 – 490 mL.
Reagent Preparation
R1 – ready to use
WR2 – Mix equal quantities from R2a and R2b and add 50:1 R3 and mix gently.
Centrifuge the solution at 3000 rpm for 3 minutes and collect the supernatant. Label
it as WR2 and it is stable for 10 days at RT.
R3 – ready to use
R4 – ready to use
Test Procedure for the peroxide test
Mix 9.8 mL. of reagent R4 with 0.1 mL. of sample, mix gently for 3 seconds. Add 50 uL. of R1 and mix gently for 3 seconds. Then, add 50 uL. of WR2 and mix gently for 3 seconds. Incubate 5 minutes at room temperature ( 15C-25C) and read the results in Electra m2 Unified Analyzer choosing the parameter P.V. in Foods.
The kit is stable for 2 years from the production date. Store it at room temperature.
