What Tests Are Required for Packaged Food Products in India?

Packaged food products are a part of everyday life, from biscuits and snacks to ready-to-eat meals, beverages, dairy products and traditional Indian sweets. For food manufacturers, maintaining product quality and safety is essential for protecting consumers and building customer trust.
But how can manufacturers determine whether their packaged food meets the relevant quality and safety standards?
Packaged food testing in India helps manufacturers assess food composition, microbiological safety, chemical contaminants and nutritional values. The tests required depend on the type of food, its ingredients, processing methods, intended shelf life and applicable Food Safety and Standards Authority of India (FSSAI) regulations.
In this guide, we explain the major categories of packaged food testing and how manufacturers can identify the right tests for their products.
Why Is Packaged Food Testing Important?
Food testing provides analytical information about a product’s quality and safety. It helps food businesses identify potential issues before their products reach consumers.
Here are some important reasons to consider food testing:
- Food safety: Helps assess potential microbiological and chemical hazards.
- Quality control: Supports consistent product quality across production batches.
- Nutritional information: Helps establish nutritional values for applicable product labels.
- Regulatory compliance: Helps manufacturers assess whether their products meet relevant food standards.
- Product development: Supports the evaluation of new formulations and ingredient changes.
- Customer confidence: Provides laboratory data that can support responsible quality assurance practices.
For food manufacturers, selecting appropriate tests is an important part of an effective quality management process.
1. Microbiological Testing of Packaged Food
Microbiological testing helps assess the presence or levels of microorganisms that may affect food safety, hygiene or product quality.
Depending on the product category, relevant tests may include:
- Total plate count or aerobic microbial count
- Yeast and mould count
- Coliform testing
- E. coli testing
- Salmonella testing
- Staphylococcus aureus testing
- Other product-specific microorganisms
For example, bakery products, dairy products, ready-to-eat foods and packaged meals may have different microbiological testing requirements.
Testing requirements depend on the applicable food category, processing conditions and relevant microbiological criteria. Not every test is necessary for every packaged food product.
2. Chemical Testing of Packaged Food
Chemical analysis helps determine the composition of food and assess selected chemical hazards or quality parameters.
Depending on the product, chemical tests may include:
- Moisture content
- Acidity or pH
- Fat content
- Protein content
- Ash content
- Relevant food additives and preservatives
- Product-specific chemical contaminants
The choice of tests depends on the food’s ingredients, product standards and intended use.
For example, moisture analysis may be relevant to biscuits and other dry foods, while acidity measurements may be useful for selected beverages, sauces and processed foods.
3. Nutritional Analysis for Food Labels
Nutritional analysis helps manufacturers determine the nutritional composition of their products and prepare accurate nutrition declarations where required.
Common nutritional parameters include:
- Energy value
- Protein
- Carbohydrates
- Total sugars
- Total fat
- Saturated fat
- Trans fat
- Sodium
Depending on the product and any nutrition or health claims, additional parameters such as dietary fibre, vitamins or minerals may also be relevant.
For example, a biscuit manufacturer may need nutritional information for its product label, while a snack manufacturer may want to evaluate the composition of a revised recipe.
Manufacturers should verify the applicable FSSAI labelling requirements and ensure that their declared values and claims are appropriately supported.
4. Heavy Metal and Chemical Contaminant Testing
Some food products may require testing for specific contaminants to assess compliance with applicable safety limits.
Examples include:
- Lead
- Arsenic
- Cadmium
- Mercury
- Relevant pesticide residues
- Mycotoxins, including aflatoxins where applicable
- Other product-specific contaminants
These tests may be relevant to selected grains, spices, nuts, agricultural products and other food categories.
The applicable contaminant limits and testing requirements vary by product. Manufacturers should identify the relevant regulatory requirements before finalising their testing plan.
5. Food Adulteration Testing
Food adulteration testing helps investigate whether a food product contains unauthorised substances, substitutes or other adulterants.
Depending on the food category, testing may be relevant to:
- Edible oils
- Milk and dairy products
- Spices and powdered ingredients
- Grains and pulses
- Other products with specific adulteration risks
The appropriate method depends on the suspected adulterant and the composition of the food. Laboratory analysis can help manufacturers and suppliers investigate quality concerns and verify selected product characteristics.
6. Shelf-Life and Stability Testing
Shelf-life evaluation helps manufacturers understand how a food product changes during storage under defined conditions.
Depending on the product, a shelf-life study may evaluate:
- Microbiological quality
- Moisture and other relevant chemical parameters
- Changes in colour, texture or flavour
- Packaging performance
- Product stability under specified storage conditions
Shelf life is influenced by ingredients, processing, packaging and storage conditions. Testing plans should therefore be designed around the specific product and the manufacturer’s intended storage conditions.
Shelf-life testing should not be confused with a single laboratory test that automatically establishes an expiry date. The findings need to be evaluated alongside suitable study design and other relevant evidence.
7. Product-Specific Testing Requirements
Different packaged foods require different testing approaches. A suitable testing plan begins by identifying the product category and the parameters relevant to it.
Examples include:
Biscuits and cookies: Moisture, nutritional composition, relevant microbiological parameters and other product-specific quality tests.
Indian sweets: Relevant microbiological, chemical and nutritional tests based on the ingredients and type of sweet.
Rice, grains and cereals: Moisture, selected contaminants, mycotoxins where relevant and other applicable quality parameters.
Dairy products: Relevant compositional, microbiological and chemical tests.
Packaged beverages: Product-specific chemical, microbiological and compositional tests.
Packaged snacks: Nutritional analysis, moisture, relevant chemical parameters and applicable safety tests.
These are examples rather than universal testing checklists. The final selection should be based on the applicable FSSAI standards, the product formulation and the intended purpose of the analysis.
How to Choose the Right Food Testing Laboratory
Selecting an appropriate food testing laboratory is an important step for packaged-food manufacturers.
Before submitting a sample, consider the following:
- Check the laboratory’s accreditation: Verify whether the laboratory holds relevant NABL accreditation and whether the specific tests fall within its accredited scope.
- Confirm the testing requirements: Identify the applicable product standards and parameters before requesting a quotation.
- Ask about testing methods: Confirm that suitable analytical methods are available for your product.
- Understand sample requirements: Follow the laboratory’s instructions for sample quantity, packaging, transport and storage.
- Confirm the reporting timeline: Ask about expected turnaround times and any additional requirements.
- Review the test report: Ensure the report covers the parameters requested and provides the information needed for your quality or compliance assessment.
A laboratory’s general accreditation status does not automatically mean that every test it offers is covered by its accredited scope.
Is Food Testing Mandatory for Packaged Food Products in India?
Food businesses must comply with the applicable provisions of the Food Safety and Standards Act, relevant regulations and the conditions attached to their licences.
Testing obligations depend on the product category and applicable requirements. The frequency, parameters and laboratory eligibility should be checked against current regulatory provisions and any relevant licence conditions.
Manufacturers should also review applicable FSSAI product standards, contaminant limits, microbiological criteria and labelling regulations before deciding on a testing programme.
