Milk & Dairy Product Testing Laboratory India | NABL & FSSAI Accredited

India produces over 230 million tonnes of milk annually, making dairy product quality and safety testing a national priority. Auriga Research operates a milk testing lab accredited by NABL (ISO/IEC 17025:2017) and approved by FSSAI, delivering compositional analysis, adulteration detection, microbiological safety testing, and nutritional profiling for liquid milk, paneer, ghee, cheese, butter, curd, ice cream, and infant formula.

Whether you are searching for a milk testing lab near me for routine FSSAI compliance or need advanced dairy adulteration screening for export markets, our laboratory provides fast turnaround with regulatory-ready certificates accepted by FSSAI licensing officers, export inspection councils, and international buyers across EU, Middle East, and South-East Asian markets.

Milk adulteration remains widespread in India — water addition, urea, starch, detergents, neutralisers, and synthetic milk components compromise consumer safety and brand reputation. Our testing protocols follow FSSAI's Manual of Methods of Analysis of Milk and Milk Products and relevant IS standards to detect all known adulterants at regulatory thresholds.

Milk & Dairy Testing Parameters

Fat content — Gerber and Rose-Gottlieb methods
Solids Not Fat (SNF) by lactometer and gravimetry
Protein content by Kjeldahl method
Added water detection — freezing point depression (cryoscopy)
Adulteration: urea, starch, glucose, detergents, neutralisers, formalin
Synthetic milk component detection by GC-MS
Microbiological: TPC, Coliform, E. coli, Salmonella, Listeria, S. aureus
Antibiotic and veterinary drug residues by LC-MS/MS
Aflatoxin M1 by ELISA and HPLC
Heavy metals (lead, cadmium, arsenic, mercury) by ICP-MS
Melamine screening
Phosphatase test (pasteurisation efficiency)

Who Needs Dairy Testing

Dairy cooperatives and milk processors for FSSAI licence compliance
Dairy brands requiring batch release and quality monitoring
Export-oriented dairy companies meeting EU, Middle East, and ASEAN standards
Infant formula manufacturers — most stringent FSSAI limits apply
Retail chains and food service companies verifying supplier quality

Turnaround Time

Routine compositional analysis is completed in 3-5 business days. Full adulteration panels take 5-7 business days. Microbiological testing requires 5-10 business days. Expedited testing is available on request.

Frequently Asked Questions

What parameters are tested in milk testing labs for FSSAI compliance?

FSSAI-compliant milk testing covers fat content (Gerber method), SNF (Solids Not Fat), protein, acidity, added water detection via freezing point depression, adulteration screening (urea, starch, detergents, neutralisers), microbiological parameters (TPC, coliforms, Salmonella, Listeria), antibiotic residues, aflatoxin M1, and heavy metals. The specific panel depends on the milk type — toned, standardised, or full cream — and the product category (liquid milk, paneer, ghee, cheese).

How do you detect adulteration in milk samples?

Our milk adulteration testing uses both rapid screening and confirmatory instrumental methods. Added water is detected by freezing point depression (cryoscopy). Starch adulteration is confirmed by iodine reaction. Urea is quantified by spectrophotometry. Detergents and neutralisers are detected by specific chemical reactions. Synthetic milk components are identified by GC-MS fatty acid profiling. Formalin and hydrogen peroxide (illegal preservatives) are detected by colorimetric methods.

What are FSSAI fat and SNF standards for different milk types?

FSSAI standards specify: Full cream milk — minimum 6.0% fat, 9.0% SNF. Standardised milk — minimum 4.5% fat, 8.5% SNF. Toned milk — minimum 3.0% fat, 8.5% SNF. Double toned milk — minimum 1.5% fat, 9.0% SNF. Skimmed milk — maximum 0.5% fat, minimum 8.7% SNF. These are minimum requirements and testing verifies compliance with both regulatory standards and the brand declared specifications on the label.

How long does dairy product testing take and what is the turnaround time?

Routine milk compositional analysis (fat, SNF, protein, acidity) is completed within 3-5 business days. Adulteration screening panels take 5-7 business days. Microbiological testing requires 5-10 business days depending on the organisms tested (Salmonella enrichment takes longer). Antibiotic residue testing by LC-MS/MS takes 7-10 business days. Expedited turnaround is available for urgent requirements — contact our laboratory for specific timelines.

Can you test dairy products for export compliance?

Yes. We test dairy products against export destination requirements including EU Commission Regulation limits, US FDA standards, and Gulf Cooperation Council (GSO) specifications. Export testing covers compositional analysis, microbiological safety, antibiotic residues (with reporting against EU MRLs), aflatoxin M1, heavy metals, and melamine. Our NABL-accredited certificates are accepted by export inspection agencies and international buyers.
