Freshness testing is a crucial quality control step that ensures food products remain safe, nutritious, and compliant with Qatar’s Ministry of Public Health (MoPH) and GCC Standardization Organization (GSO) regulations.
Our ISO/IEC 17025-accredited laboratory in Doha, Qatar offers comprehensive freshness analysis for seafood, honey, and dairy products, ensuring your products meet regulatory and consumer expectations for quality and safety.
We specialize in testing key freshness indicators, including:
These parameters confirm compliance with Qatar Food Safety Law No. (8) of 1990, GSO specifications, and Codex Alimentarius standards.
All freshness testing services are performed following Qatari and GCC regulatory standards, ensuring international traceability and acceptance.
Applicable Regulations:
Our testing methods are accredited under ISO/IEC 17025 and approved by the Qatar MoPH Food Safety Department for import clearance, labeling, and regulatory verification.
TVB-N measures nitrogenous compounds (ammonia, dimethylamine, trimethylamine) produced during protein degradation — a key indicator of spoilage in seafood and meat.
Distillation–Titration / Kjeldahl Method
≤ 30 mg/100 g (as per GSO 989/2015)
Ensures fish freshness and prevents sale of decomposed or non-compliant seafood.
Histamine forms in protein-rich fish due to bacterial activity. Excess levels can cause scombroid poisoning, making monitoring essential for seafood safety and MoPH compliance.
HPLC / Fluorometric Detection
≤ 100 mg/kg (GSO 323/1994)
HMF forms when honey is overheated, adulterated, or aged. Low HMF levels indicate natural, unprocessed honey with preserved enzymatic and nutritional quality.
Spectrophotometric (White Method) / HPLC
≤ 40 mg/kg (GSO 147/2011)
GSO 147/2011 – Honey Specifications
Diastase is a natural enzyme that breaks down starch in honey. Reduced activity indicates overheating, poor storage, or aging.
Schade Method / Phadebas Assay
≥ 8 DN (Diastase Number) (GSO 147/2011)
Freshness testing is essential to maintaining consumer confidence, preventing product spoilage, and achieving regulatory approval.
