Food Preservatives Exposed: What FSSAI Says and How to Read a Food Label Like a Pro
Did you know that the average Indian consumes packaged food every single day — yet 9 out of 10 people can't name a single preservative listed on the label? That's not a coincidence. It's by design.
Food preservatives are everywhere — in your favourite namkeen, biscuits, ready-to-eat meals, and even in the "healthy" granola bars you reach for in the morning. But are all of them dangerous? Or are some perfectly safe? And more importantly — what does India's food safety regulator, FSSAI, actually permit?
In this guide, you'll learn exactly what food preservatives are, which ones FSSAI allows (and in what quantities), how to decode those confusing ingredient labels, and why choosing preservative-free snacks is becoming the smarter — and tastier — choice.
of packaged food products sold in India contain at least one chemical preservative. That's a massive number — and a strong reason to understand exactly what you're eating.
What Are Food Preservatives? (And Why Are They Used?)
Food preservatives are substances added to food products to prevent spoilage caused by bacteria, mould, yeast, or oxidation. They extend shelf life, maintain colour, and keep food "fresh" for longer — a critical requirement in a country as large and warm as India.
There are two broad categories:
Salt, sugar, vinegar, lemon juice, turmeric. Used for centuries in Indian cooking.
Sodium benzoate, potassium sorbate, BHA, BHT, EDTA. Lab-made and widely used in packaged foods.
What Does FSSAI Say About Food Preservatives?
The Food Safety and Standards Authority of India (FSSAI) regulates which preservatives can legally be used, in which food categories, and at what maximum permitted levels (MPLs). This is governed under the Food Safety and Standards (Food Products Standards and Food Additives) Regulations, 2011.
Permitted Preservatives Under FSSAI
Here are some commonly approved preservatives and what you should know:
Permitted in carbonated drinks, squashes, and fruit-based products up to 600 mg/kg. Studies suggest it may convert to benzene (a known carcinogen) when combined with Vitamin C — something very common in flavoured drinks.
Widely used in cheese, bakery products, and dried fruits. FSSAI permits it up to 1000 mg/kg in certain products. Generally considered safer than benzoate, but excessive consumption may disrupt gut flora.
Common in dried mango, raisins, and fruit juices. Can trigger asthma and allergic reactions in sensitive individuals. FSSAI mandates labelling if sulphites exceed 10 mg/kg — a key label fact to check.
Used in fried snacks, instant noodles, and oils. The International Agency for Research on Cancer (IARC) has flagged BHA as a possible human carcinogen. FSSAI permits limited use, but these are best avoided whenever possible.
Under the Labelling Regulations, any food additive (including preservatives) must be listed in the ingredient declaration along with its functional class name (e.g., "Preservative") and either its name or INS number.
How to Read a Food Label Like a Pro
This is where most consumers get stuck. The label looks complicated — but once you know the pattern, it takes under 60 seconds.
Look at the Ingredient List
Ingredients are listed in descending order of weight. So the first three ingredients make up the bulk of your food. If a preservative appears in the first five ingredients, that's a high amount.
Spot the INS Numbers
Any number starting with INS followed by digits is a food additive. Preservatives typically fall in the INS 200–299 range (antimicrobials) and INS 300–399 (antioxidants used as preservatives). Cross-reference these numbers to understand what you're consuming.
Check the "Contains" Declaration
FSSAI mandates disclosure of major allergens and certain additives. If you see "Contains Sulphites" — that's a FSSAI-mandated warning you should take seriously, especially if you have asthma or respiratory sensitivities.
Don't Fall for "No Artificial Colours" Traps
A product can claim "No Artificial Colours" while still being loaded with synthetic preservatives. These are different categories. Read the full ingredient list — not just the front-of-pack claims.
Prioritise Short Ingredient Lists
A good rule of thumb: if you can't pronounce more than two ingredients, it's worth investigating. Whole food-based snacks typically have 5–7 ingredients. Highly processed snacks often list 20+.
FSSAI's official Food Safety Connect app lets you scan a product and check its licensing and compliance status in seconds.
Natural vs. Synthetic Preservatives: Which Is Safer?
This isn't a black-and-white answer — but the evidence leans heavily toward natural.
Natural preservatives like salt, jaggery, tamarind, and turmeric have been used safely in Indian food culture for thousands of years. They preserve food while also adding nutritional or functional value.
Synthetic preservatives are tested for safety in isolation, but long-term cumulative exposure — eating multiple preservative-containing products daily — is a growing concern. A 2019 Indian study published in the Journal of Food Science and Technology found that children consuming high levels of sodium benzoate showed elevated markers of oxidative stress.
One biscuit with potassium sorbate isn't a crisis. But when your breakfast, lunch, evening snack, and packaged juice all contain different synthetic preservatives, the body's detox burden adds up.
Why More Indian Families Are Choosing Preservative-Free Snacks
of Indian urban consumers actively check ingredient labels before purchasing — up from just 29% in 2018. That's a massive shift in consumer behaviour.
Parents, especially, are making different choices. School tiffins are evolving. The demand for clean-label snacks — made without synthetic preservatives, artificial colours, or unnecessary additives — has grown over 35% in India's packaged snack segment over the last three years.
At Beansy Foods, we believe that what's not in your food matters just as much as what is. Our snacks are crafted with real ingredients, with no synthetic preservatives — because good food shouldn't need a chemistry degree to understand.
Common Myths About Food Preservatives — Busted
Busted: FSSAI approval means it's permitted within specific limits. It doesn't mean unlimited consumption is harmless. Context, quantity, and cumulative exposure all matter.
Busted: Salt and sugar are natural — but in excessive amounts, they cause serious health issues. Natural doesn't automatically mean healthier. Balance matters.
Busted: Smart formulations using vinegar, lemon juice, natural acidity, or controlled packaging can extend shelf life without any synthetic additives. Many clean-label brands are proving this daily.
Your Preservative Cheat Sheet: INS Numbers to Watch
| INS Number | Name | Common Use | Watch Out If... |
|---|---|---|---|
| INS 211 | Sodium Benzoate | Drinks, sauces | Combined with Vit C |
| INS 202 | Potassium Sorbate | Bakery, dairy | Gut sensitivity |
| INS 220 | Sulfur Dioxide | Dried fruits | Asthma/allergies |
| INS 320 | BHA | Fried snacks, oils | Regular consumption |
| INS 321 | BHT | Instant noodles | Children's diets |
The Bottom Line: Eat Informed, Eat Better
Food preservatives are not automatically evil — but they deserve your attention. FSSAI sets the rules, but you set the standard for your own family's health. Reading labels isn't paranoia; it's self-care.
Start small: next time you pick up a packet of biscuits or namkeen, flip it over. Look for the INS numbers. Count the ingredients. Ask yourself — does this match the clean, wholesome snacking you actually want?
If you're ready to switch to snacks that are honest about every ingredient they use — and proud of their short, clean ingredient lists. Real ingredients, real taste, no compromise.
