Why it matters
Why reading food labels changes everything
The problem with packaged food
Every packaged food product lists ingredients on its label — but most of those names are chemical compounds that mean nothing to the average consumer. Additives are often listed by their scientific names (INS 621, E102, E220) or by marketing-friendly aliases ("yeast extract", "natural flavours", "vanaspati") that hide what they really are. Without a tool to decode them, you are buying blind.
Hidden health risks
Many common food additives are linked to health concerns — from hyperactivity in children (artificial colours like E102, E110, E129) to cancer risks (formaldehyde-releasing preservatives, titanium dioxide). Some additives that are legal in India are banned in the European Union, Japan, or Australia. The label on the pack never tells you this. TheFoodScanner does.
Daily safe limits matter
Even harmless-sounding additives can become problematic in large quantities. Aspartame, for example, has a WHO-recommended acceptable daily intake (ADI) of 40 mg per kg of body weight. A single can of diet soda can contain 180 mg — and if you drink several per day, you may be approaching the limit. TheFoodScanner shows you the daily safe limit for every additive it detects, so you can make informed choices about quantity.
What "banned abroad" really means
Regulatory bodies around the world do not always agree on what is safe. The European Union bans several artificial colours that remain legal in India. Japan restricts specific preservatives that the FDA allows. When TheFoodScanner flags an additive as "banned abroad", it means one or more major regulatory body (EU, Japan, Australia) has restricted or prohibited that additive — giving you context that the on-pack label never provides.
It is not about fear — it is about information
TheFoodScanner does not tell you to stop eating packaged food. It gives you the information to decide for yourself. Some additives are perfectly safe; others carry real risks at high doses or for specific groups (children, pregnant people, people with allergies). Knowing which is which is the difference between buying blindly and buying wisely.
Built for the Indian consumer
Indian food labels use INS numbers, FSSAI-regulated names, and region-specific ingredient terminology that generic barcode scanners cannot handle. TheFoodScanner is tuned for the Indian shelf — it reads INS codes, vanaspati, "yeast extract", ajinomoto, and dozens of other Indian-context names that foreign tools miss entirely.
How it works
Three steps. Ten seconds. Zero uploads.
TheFoodScanner works entirely in your browser — there is nothing to install, no account to create, and no photo uploaded to any server. Here is exactly how the process works:
01
Scan or upload
Open the scanner in your browser — Chrome, Safari, or any modern mobile browser. Point your camera at the ingredients panel on the back of the pack, or upload a photo you already have. The scanner frames the text and captures it.
OCR runs entirely in your browser via Tesseract.js. Your photo is never sent to a server.
02
We decode it
Every ingredient line is extracted and matched against our curated hazard database — over 300 additives indexed by INS code, chemical name, and the brand-name synonyms that manufacturers use to disguise them. Each match is classified by hazard level: Very Dangerous, Dangerous, Moderate, Low Risk, or Safe.
Data sourced from JECFA, EFSA, FDA, FSSAI, IARC, and WHO classifications.
03
Get the verdict
A 0–10 health hazard score based on the weighted severity of detected additives. Each additive shows its plain-English meaning, daily safe limit, and where it is banned abroad. If the score is 7 or above, healthier clean-label alternatives are suggested.
The score is a weighted sum — Very Dangerous additives count more than Low Risk ones.
What we detect
Additives we decode — and why they matter
TheFoodScanner tracks over 300 food additives across eight major categories. Here are the most common ones you will find on Indian packaged food labels:
Preservatives
Sodium benzoate (E211), potassium sorbate (E202), calcium propionate (E282), and formaldehyde-releasing agents. Used to extend shelf life but linked to hyperactivity and allergic reactions.
Artificial sweeteners
Aspartame (E951), sucralose (E955), acesulfame potassium (E950), and saccharin (E954). Zero-calorie sugar substitutes with ongoing debates about long-term safety and gut health effects.
Flavour enhancers
Monosodium glutamate / MSG (E621), disodium inosinate (E631), and disodium guanylate (E627). Used to boost taste but associated with headaches, flushing, and sensitivity reactions in some people.
Artificial colours
Tartrazine (E102), sunset yellow (E110), allura red (E129), and brilliant blue (E133). Banned or restricted in multiple countries due to links to hyperactivity in children.
Emulsifiers
Polysorbate 80 (E433), carboxymethyl cellulose (E466), and soy lecithin (E322). Help blend ingredients but may disrupt gut bacteria and intestinal lining in emerging research.
Thickeners
Methylcellulose (E461), carrageenan (E407), and xanthan gum (E415). Improve texture but some are linked to digestive issues and inflammation at high intake levels.
Antioxidants
BHA (E320), BHT (E321), and TBHQ (E319). Prevent rancidity but classified as possible or probable carcinogens by IARC and other agencies.
Controversial additives
Titanium dioxide (E171) — banned in EU since 2022. Vanaspati (partially hydrogenated oil). "Natural flavours" — a catch-all term that can hide dozens of undisclosed chemicals.
Our data sources
Graded against the world’s food safety authorities
TheFoodScanner does not guess. Every additive is classified using data from six major international food safety bodies. This is the same data that regulators, researchers, and food scientists use worldwide.
JECFA
Joint FAO/WHO Expert Committee on Food Additives
The global gold standard for food additive safety evaluation. JECFA establishes acceptable daily intakes (ADIs) and evaluates the toxicological data for additives used worldwide.
EFSA
European Food Safety Authority
The EU’s food safety watchdog. EFSA has banned or restricted several additives that remain legal elsewhere, including titanium dioxide (E171) and certain artificial colours.
FDA
U.S. Food and Drug Administration
Regulates food additives in the United States. The FDA maintains the GRAS (Generally Recognized As Safe) list and publishes safety assessments for approved additives.
FSSAI
Food Safety and Standards Authority of India
India’s food regulator. FSSAI sets permissible additive limits for the Indian market and publishes the Food Safety and Standards (Food Product Standards and Food Additives) Regulations.
IARC
International Agency for Research on Cancer
The WHO’s cancer research agency. IARC classifies substances into groups based on cancer risk — from Group 1 (carcinogenic) to Group 3 (not classifiable). Used to flag additives with cancer concerns.
WHO
World Health Organization
Publishes guidelines on acceptable daily intakes, trans fat limits, and food safety standards used globally. The WHO ADI values are used as the benchmark for daily safe limits shown in scan results.
Who it’s for
Built for anyone who reads a food label
Parents
Check whether the snack you are buying your child contains artificial colours linked to hyperactivity, or preservatives that multiple countries have banned. Know what your family is eating — not just what the packaging claims.
Fitness enthusiasts
Track what goes into your body beyond calories and macros. Discover hidden additives in protein bars, supplements, and "health" foods that market themselves as clean but are loaded with artificial sweeteners and preservatives.
Expectant mothers
Pregnancy increases sensitivity to certain additives. TheFoodScanner helps you quickly verify whether a packaged food contains ingredients that major health bodies advise limiting during pregnancy — without spending hours researching each chemical name.
Everyday shoppers
Standing in a supermarket aisle with two similar products? Scan both labels in seconds and compare their health hazard scores. Make the better choice without needing a chemistry degree or spending ten minutes reading fine print.
Scan before you buy.
The next time a label looks innocent, run it through TheFoodScanner first. You might be surprised by what is hiding in plain sight on your grocery shelf.
