Data & Scoring Disclaimer

Last updated: 5 April 2026

Data Sources

IngredScan aggregates product data from multiple sources:

  • Open Food Facts — a free, open, collaborative database of food products
  • UK Food Standards Agency (FSA) — food safety and additive regulations
  • USDA FoodData Central — nutritional reference data
  • Supermarket product pages — supplementary product information

Important: Data from these sources may be incomplete, outdated, or incorrect. Product formulations change frequently. Always verify information by reading the actual product label.

How the NOVA Score Is Calculated

The NOVA classification system was developed by researchers at the University of Sao Paulo, Brazil. It groups foods into four categories based on their level of processing:

NOVA 1 — Unprocessed or Minimally Processed

Fresh or minimally altered foods. Examples: fresh fruit, vegetables, eggs, plain rice, fresh meat, milk, plain nuts.

NOVA 2 — Processed Culinary Ingredients

Substances extracted from NOVA 1 foods, used in cooking. Examples: olive oil, butter, sugar, salt, flour, vinegar.

NOVA 3 — Processed Foods

NOVA 1 foods modified by adding NOVA 2 ingredients. Usually 2-3 ingredients. Examples: tinned vegetables, cheese, freshly baked bread, cured meats, tinned fish.

NOVA 4 — Ultra-Processed Foods (UPF)

Industrial formulations with 5+ ingredients, typically including substances not used in home cooking (e.g. high-fructose corn syrup, hydrogenated oils, emulsifiers, flavour enhancers). Examples: soft drinks, packaged biscuits, crisps, instant noodles, chicken nuggets, most breakfast cereals.

How the Quality Score Is Calculated

The IngredScan Quality Score is a proprietary rating from 0 to 10, calculated using the following formula:

Base score: 10.0

-1.5 per NOVA 4 additive (max penalty: -4.0)

-1.0 if Nutri-Score is D or E

-0.5 if Nutri-Score is C

-1.0 if saturated fat > 5g per 100g

-0.5 if sugar > 10g per 100g

-1.0 if salt > 0.6g per 100g (UK FSA threshold)

+0.5 if product is certified organic

The final score is clamped between 0.0 and 10.0. A higher score indicates a product with fewer ultra-processed additives, better nutritional profile, and less concerning ingredients.

Regulatory Framework

United Kingdom (England, Scotland, Wales): Food additive safety in Great Britain is governed by UK assimilated law — retained EU regulations that became part of UK domestic law following Brexit and are now published on legislation.gov.uk. The Food Standards Agency (FSA) is the primary authority, maintaining a public register of approved additives at food.gov.uk.

Northern Ireland: Follows EU food regulations under the Windsor Framework. EU Regulation (EC) No. 1333/2008 directly applies.

Post-Brexit Divergence: Since Brexit, the UK and EU food safety regulators operate independently. In most cases their decisions align, but differences exist. A notable example is Titanium Dioxide (E171), which was banned in EU food in 2022 but remains permitted in Great Britain following an independent FSA review. Where we are aware of UK/EU differences, we flag these clearly.

United States: Food additive safety is governed by the FDA under Title 21 of the Code of Federal Regulations (21 CFR). Additives may be classified as GRAS (Generally Recognized as Safe).

Additive Risk Ratings

Each additive in our database is classified as low, medium, or high risk. These classifications are based on:

  • UK FSA Approved Additives Register and UK assimilated food law
  • EFSA scientific opinions — European Food Safety Authority assessments
  • FDA 21 CFR and GRAS database — US regulatory assessments
  • Peer-reviewed scientific literature — published studies on additive safety

Risk ratings are relative classifications — "high risk" means an additive has more published concerns relative to others, not that it is necessarily dangerous at levels found in food. All additives permitted in UK food have passed regulatory safety assessments and are considered safe within established limits.

Cosmetic Product Scoring

IngredScan also analyses cosmetic products using data from Open Beauty Facts and the EWG Skin Deep database. Cosmetic safety scores are calculated by analysing the INCI (International Nomenclature of Cosmetic Ingredients) ingredient list against published scientific literature and EU/UK regulatory status.

Our cosmetic Safety Score (0-10) applies deductions for high-risk ingredients (carcinogens, endocrine disruptors, formaldehyde releasers), medium-risk ingredients (potential sensitisers, parabens), and adds small bonuses for positive certifications (vegan, cruelty-free, fragrance-free).

Important: IngredScan cosmetic scores are for informational purposes only and should not replace advice from a qualified dermatologist or healthcare professional. Individual skin reactions vary — an ingredient rated low risk may still cause reactions in sensitive individuals. If you have a known skin allergy or condition, always patch test new products and consult a dermatologist before use.

Products IngredScan Does Not Cover

Infant Formula and Baby Milk

IngredScan does not score infant formula or baby milk products. When these products are detected, we show official NHS guidance instead. Infant formula is governed by strict UK and EU nutritional regulations and should not be compared using standard food processing scores.

Medicines and Pharmaceutical Products

IngredScan does not identify or analyse medicines, prescription drugs, OTC medicines, or pharmaceutical products. If a medicine is scanned, we will tell you clearly that we cannot help and direct you to appropriate resources.

Dietary Supplements

IngredScan does not currently score dietary supplements, vitamins, or sports nutrition products. Supplement scanning is planned for a future update.

Incorrect Identification

If IngredScan incorrectly identifies a food product as a medicine or formula, or vice versa, please use the 'Report incorrect product' button on the result page. We review all reports and correct misidentifications promptly.

Fresh Produce

Fresh, whole produce (fruits, vegetables, raw meat, eggs, etc.) is always classified as NOVA 1 — unprocessed or minimally processed. If you scan a fresh product and it shows a different NOVA classification, this is an error. Please use the Report feature to let us know.

Reporting Errors

If you find incorrect product data, inaccurate scores, or missing information:

  • Tap the Report button on any product result page
  • Describe what appears to be incorrect
  • Reports are reviewed within 7 days
  • Verified corrections are applied to our database and submitted back to Open Food Facts
