What Are All These Numbers Anyway?
When you see 'Preservative (INS 211)' or 'Colour (INS 102)' on a packet of chips or a bottle of sauce, you're looking at the International Numbering System (INS) for Food Additives. This is a global standard used to identify food additives, regulated
in India by the Food Safety and Standards Authority of India (FSSAI). Manufacturers are required to list these additives, either by their full name or their INS number. They often choose the number because it's shorter and, frankly, less intimidating than a long chemical name. You might also see 'E-numbers', which are used in Europe; often, the number is the same as the INS code (e.g., E102 is the same as INS 102).
A Simple Way to Break the Code
Instead of trying to memorise hundreds of numbers, a more practical approach is to understand their categories. The first digit of the code gives you a big clue about the additive's job. Here’s a quick breakdown of the most common ranges you'll find on Indian products: 100-199 are Colours. These are used to add or restore colour to food. Examples include Tartrazine (INS 102) and Sunset Yellow (INS 110), often found in brightly coloured sweets, drinks, and snacks. 200-299 are Preservatives. Their job is to extend shelf life and prevent food from being spoiled by bacteria, moulds, or yeast. This is a crucial category in a climate like India's. Common examples are Sodium Benzoate (INS 211) in sauces and juices, and Sorbates in cheese and baked goods. 300-399 are Antioxidants and Acidity Regulators. Antioxidants, like BHA (INS 320), prevent fats and oils from going rancid, while acidity regulators like Citric Acid (INS 330) control the pH level of the food. 400-499 are Thickeners, Stabilisers, and Emulsifiers. These additives improve the texture and consistency of foods, preventing ingredients from separating in products like ice cream, jams, and sauces.
Class I vs. Class II: What's the Difference?
You might see 'Contains Permitted Class II Preservative' printed on a label. In India, preservatives are divided into two main categories. Class I preservatives are natural substances that you might even have in your kitchen, like salt, sugar, vinegar, and spices. Class II preservatives are artificial or synthetic chemicals, such as benzoates, sorbates, and sulphites. These are used because they are often more effective in small quantities. FSSAI has set strict limits on the amount of Class II preservatives that can be used in different foods to ensure they are safe for consumption.
Common Additives to Watch For
While all permitted additives are considered safe within specified limits by FSSAI, some people prefer to limit their intake of certain types. Here are a few you'll frequently see on Indian shelves: Monosodium Glutamate (MSG / INS 621): A flavour enhancer that gives food a savoury 'umami' taste, common in instant noodles, chips, and soups. Sodium Benzoate (INS 211): A preservative found in acidic foods like soft drinks, jams, and pickles. Artificial Colours (INS 102, 110, 129): These dyes, like Tartrazine and Sunset Yellow, are used for visual appeal but have been linked to sensitivity in some individuals. Nitrates and Nitrites (INS 249-252): Used primarily in cured and processed meats like sausages and ham to preserve colour and prevent bacterial growth. Awareness of these common codes allows you to make a quicker, more informed choice without feeling overwhelmed.
Your Practical Shopping Strategy
Deciphering labels isn't about eliminating all additives, but about making conscious choices. Start by reading the ingredients list, not just the claims on the front of the package. According to FSSAI rules, ingredients must be listed in descending order by weight, so the first three ingredients make up the bulk of the product. A good rule of thumb is that a shorter ingredient list often means a less processed product. If you see several INS numbers, especially for colours and preservatives, you know the product is highly processed. Don't panic about every number; instead, focus on making gradual changes, perhaps by choosing a brand with fewer additives or opting for fresh, whole foods whenever possible. The goal is empowerment, not fear.
