Acid Value and Peroxide Value Rapid Test Strips-for Oils
Brand: FSTest
1–3 mins Rapid Readout Time | Dual AV / PV Simultaneous Testing | 3 Pack Options Multiple Specifications | 18 Months Shelf Life (2–30°C) |
The FSTest Acid Value and Peroxide Value Rapid Test Strips - for Oils are dual-parameter chemical colorimetric indicator strips designed for semi-quantitative visual determination of Acid Value (AV) and Peroxide Value (PV) in various liquid oils and fats.
As cooking oils undergo thermal degradation and hydrolysis during frying or storage, free fatty acids (Acid Value / AV) and lipid peroxides (Peroxide Value / PV) accumulate, producing harmful decomposition products and off-flavors. These rapid test strips allow food service operators, catering supervisors, oil processing plants, and QA inspectors to perform instant, tool-free oil freshness screening directly on-site in just 1 to 3 minutes.
Multiple Specification Options: Available in Item 24114, 24115, and 24107 to meet different operational throughput requirements.
Ultra-Fast On-Site Readout: Yields clear visual color reaction results within 1–3 minutes directly from warm or ambient oil samples.
Tool-Free Operation: Requires no reagents, solvents, glass titrations, or electronic analyzers—simply dip and match against the standard color card.
Broad Oil Applicability: Validated across vegetable oils (soybean, palm, sunflower, peanut, olive) and animal fats used in deep-frying or food processing.
Moisture-Proof Packaging: Supplied in sealed desiccant-lined containers to preserve pad sensitivity and guarantee an 18-month shelf life.

Validated for multi-matrix oil freshness verification across commercial food service and industry:
STEP 1 Oil Sampling Take a representative oil sample. Ensure hot frying oil is allowed to cool down to 20–40°C before dipping. | STEP 2 Dip Strip Remove a test strip from the bottle and immediately recap tight. Immerse both reaction pads into the oil sample for exactly 1–2 seconds. | STEP 3 Wipe Excess Remove strip and gently edge against the container rim or clean absorbent paper to remove excess oil. Start timing immediately for 60–180 seconds. | STEP 4 Color Matching Compare pad colors with the standard colorimetric scale on the vial label within the specified reaction time to read AV and PV values. |
Acid Value (AV) Pad: Color transitions from green to yellow/tan depending on free fatty acid content. Compare against the AV color blocks (0 to 5.0 mg KOH/g). Exceeding regulatory limits (e.g., >3.0 mg KOH/g) indicates oil discard threshold.
Peroxide Value (PV) Pad: Color changes from white/light pink to deep violet/purple based on peroxide accumulation. Match with PV color blocks (0 to 60 meq/kg) to evaluate primary oxidative breakdown.
Operational Decision: High AV or PV values indicate oil exhaustion and degradation, signaling the necessity for immediate oil filtering or vat replacement.
Adhere to strict operational parameters to ensure maximum screening accuracy:
Oil Temperature Safety: Do not dip strips into boiling hot oil (>100°C) to prevent thermal destruction of chemical reagents. Cool sample to 20–40°C.
Desiccant Cap Protection: Always recap the container tightly immediately after pulling strips to avoid pad degradation from ambient air humidity.
Timing Precision: Read visual pad color changes strictly within the recommended time window (1–3 minutes); colors observing beyond 5 minutes may shift due to ambient oxidation.
Kit Components Included: Test strips, Standard Colorimetric Scale Card, User Manual.
Required Equipment (Not Provided): Clean sampling cup/dropper, timer, and absorbent paper wipes.
