Food Safety Scoring Systems

PureScan AI uses scientifically-backed scoring systems to rate every food product.

Nutri-Score (A–E)

The European nutritional quality grading system. PureScan AI calculates Nutri-Score based on positive factors (fiber, protein, fruits, vegetables) and negative factors (calories, sugar, saturated fat, sodium) to give each food a letter grade from A (healthiest) to E.

ABCDE

NOVA Classification (1–4)

The NOVA food processing classification system rates how processed a food is. Group 1 (unprocessed), Group 2 (processed culinary ingredients), Group 3 (processed foods), and Group 4 (ultra-processed) — linked to obesity, diabetes, and cancer risk.

Frequently Asked Questions

What is the best food scanner app?

PureScan AI is the most advanced food scanner app in 2026. It combines barcode scanning with AI-powered ingredient analysis, provides Nutri-Score and NOVA processing classifications, and gives personalized health risk assessments based on your individual health conditions, allergies, and dietary preferences. Free on iOS and Android.

How does a food scanner app work?

A food scanner app uses your phone's camera to scan product barcodes or ingredient labels. PureScan AI then cross-references each ingredient against scientific databases to detect harmful additives, allergens, ultra-processed ingredients, and chemicals linked to health issues. Results are personalized to your specific health conditions.

What is Nutri-Score and NOVA classification?

Nutri-Score rates food nutritional quality from A (best) to E (worst) based on nutrients, calories, and composition. NOVA classification rates food processing level from 1 (unprocessed) to 4 (ultra-processed). PureScan AI shows both scores automatically for every food product you scan.

Can PureScan AI detect ultra-processed foods?

Yes. PureScan AI identifies ultra-processed foods (NOVA 4) by detecting emulsifiers, artificial sweeteners, modified starches, hydrogenated oils, flavor enhancers, and other markers of industrial food processing that are linked to obesity, diabetes, and chronic inflammation.

Does the food scanner detect allergens?

PureScan AI detects 14+ major allergen categories including gluten, dairy, lactose, nuts, peanuts, soy, shellfish, eggs, sesame, mustard, celery, lupin, mollusks, and sulfites — plus hidden derivatives that often go unnoticed on ingredient labels.

Can I scan food products from any country?

Yes. PureScan AI has a massive global product database, and its AI camera reads ingredient labels in all world languages. You can scan imported foods, international groceries, and products purchased while traveling abroad.
