Packaged Food
Packaged food has become a staple in modern households due to its convenience, variety, and longer shelf life. However, it is essential to ensure that these foods are safe, nutritious, and free from adulteration, contamination, or any other factors that could compromise quality. The Food Safety and Standards Authority of India (FSSAI) sets stringent guidelines for the analysis of packaged food to ensure that these products meet food safety standards and provide accurate information to consumers. The analysis of packaged food involves assessing its physicochemical, microbiological, organoleptic, and sensory characteristics to confirm its safety, quality, and compliance with labeling norms.
Parameters for Analysis as per FSSAI
1. Physical & Organoleptic Parameters
| Parameter | Packaged Food |
| Appearance | Clean, free from visible contamination, foreign matter, or damage |
| Color | Consistent color, no discoloration or off-color |
| Odor | Fresh, characteristic of the product, no rancid, stale, or off odor |
| Texture | Smooth, consistent, free from lumps, separation, or foreign particles |
| Taste | Fresh, natural flavor characteristic of the food item, no bitterness or off-flavors |
| Packaging Integrity | No punctures, tears, or damage to the packaging, airtight, moisture-proof |
| Foreign Matter | Free from non-food materials like glass, metal, or plastic particles |
2. Chemical Parameters
| Parameter | Packaged Food |
| Moisture Content | Generally ≤ 10-12% (depending on the type of food) |
| Ash Content | Varies by food type, typically 1-10% |
| Total Fat | Varies by food type, e.g., <10% for low-fat products |
| Crude Protein | Varies by food type, typically 5-20% |
| Carbohydrates | Varies, typically 30-80% depending on the product |
| Total Sugars | Varies, typically <10% for unsweetened foods |
| Salt/Sodium | < 1-2%, depending on the type of packaged food (high in salty snacks, lower in others) |
| Acidity (pH) | Typically 5.5-7, depending on the product |
| Preservatives | Within permissible limits (e.g., sodium benzoate, potassium sorbate) |
| Additives | Should be as per the allowable limits (e.g., emulsifiers, stabilizers, etc.) |
| Heavy Metals | Should be within FSSAI limits: Lead (Pb) < 2 ppm, Arsenic (As) < 1 ppm, Cadmium (Cd) < 1 ppm, Mercury (Hg) < 0.1 ppm |
3. Microbiological Parameters
| Parameter | Packaged Food |
| Total Plate Count (CFU/g) | ≤ 10^5 CFU/g (depending on the food type, e.g., less for dry food, more for perishable products) |
| Yeast & Mold Count (CFU/g) | ≤ 10^3 CFU/g (for dry foods, ≤ 10^2 for high-moisture foods) |
| E. coli | Should be absent |
| Salmonella spp. | Should be absent |
| Staphylococcus aureus | Should be absent |
| Listeria monocytogenes | Should be absent |
| Clostridium perfringens | Should be absent |
| Coliform Count | ≤ 10/g (varies based on food type) |
| Bacillus cereus | Should be absent or ≤ 10^3/g |
4. Additives & Contaminants
| Parameter | Packaged Food |
| Artificial Colors | Should be within legal limits (e.g., Tartrazine, Sunset Yellow) |
| Artificial Flavors | Should be within legal limits (e.g., Vanillin, Butyl Acetate) |
| Preservatives | Should be within permissible limits (e.g., Sodium Benzoate, Potassium Sorbate) |
| Flavor Enhancers | Should be within permissible limits (e.g., Monosodium Glutamate) |
| Sweeteners | Should be within permissible limits (e.g., Aspartame, Saccharin) |
| Adulterants | Should be absent (e.g., starch, synthetic additives) |
| Pesticide Residues | Should be within FSSAI limits |
5. Sensory & Organoleptic Evaluation
| Parameter | Packaged Food |
| Appearance | Uniform, no discolouration or damage, no visible contamination |
| Odor | Fresh, characteristic of the food item, no off or musty odours |
| Taste | Balanced flavour, no bitterness, rancidity, or sourness |
| Texture | Smooth, consistent, free from lumps, no separation or curdling |
| Color | Uniform, no color variations or unnatural color |
| Packaging | Tightly sealed, no leakage, intact seals, correct labeling |
6. Shelf-life & Packaging Quality
| Parameter | Packaged Food |
| Shelf-life Stability | Stable for the stated shelf life under appropriate storage conditions (e.g., cool, dry, and dark storage) |
| Packaging Integrity | Airtight, moisture-proof, tamper-proof packaging |
| Labeling Compliance | Correct and complete labeling (e.g., ingredients, nutritional information, allergen labeling, batch number, manufacturing date, and expiry date) |
| Storage Conditions | Should follow recommended storage conditions, such as refrigeration or freezing if required |
7. Labeling Compliance (FSSAI Guidelines)
| Parameter | Packaged Food |
| FSSAI Logo and License Number | Must be displayed clearly on the packaging |
| Nutritional Information | Must include energy (kcal), fat (g), protein (g), carbohydrates (g), and fibre (g) |
| Ingredient List | All ingredients must be listed in descending order of weight |
| Allergen Information | Should specify if the product contains common allergens (e.g., nuts, dairy, gluten) |
| Batch Number and Manufacturing Date | Must be clearly mentioned |
| Expiry Date | Must be mentioned in the format “Best Before” or “Use By” Date |
The analysis of packaged food as per FSSAI standards ensures that food products are safe, nutritious, and of high quality. By following the guidelines for physical, chemical, microbiological, and sensory evaluations, manufacturers can guarantee the safety and quality of packaged food for consumers. Moreover, proper labelling compliance ensures that consumers have access to accurate information regarding the product, including nutritional content, ingredient list, and allergen warnings. By adhering to FSSAI standards, packaged food manufacturers can build consumer trust and contribute to public health.
