Every nutrient. Every portion. No gaps.
Turn any recipe, in any unit, into reliable micro- and macronutrient data.
Problem
Recipe portals like Chefkoch show almost no reliable nutrition values. Recipes use household units — pieces, tablespoons, teaspoons, a handful, “half of it” — not grams.
The German food database (BLS) gives values per 100 g, but nobody cooks in 100 g steps. Add international units (g/kg in Germany, cup/oz in the US) and almost no recipe has correct calories — let alone macro/micronutrients or trustworthy diet properties.
Hypotheses
- Household units can be reliably normalised to grams per ingredient — including DE↔US conversion.
- On the BLS basis, all macro- and micronutrients can be computed with a bounded, declared rounding error.
- Diet properties (gluten-free, lactose-free, vegan, vegetarian, low carb/fat) are derivable by rules from nutrient and amino-acid profiles — not manually.
- Providers massively upgrade their recipes when nutrition values appear automatically and completely.
Target metrics
- Coverage: share of recipes with a complete nutrition profile
- Accuracy versus lab reference
- Maximum rounding error per unit
- Hit rate of automatic diet classification
KPIs
- ~99% of submitted recipes with a complete nutrition profile
- Bounded, declared maximum rounding error per conversion
- All common household and country units normalised (DE/US)
- Auto labels: low carb, low fat, lactose-free, gluten-free, vegan, vegetarian
Outcome
A recipe portal without nutrition data becomes one with precise, comparable values — the only solution worldwide that reliably turns any recipe in any unit into micro- and macronutrients.
This enables real filtering and search like “gluten-free under 500 kcal” and builds user trust.
Output
- Unit normalisation engine (household & country units → grams)
- BLS-based nutrition calculator for macro- and micronutrients
- Rule set for diet classification (incl. gluten-free via amino acids)
- A complete, verified nutrition and property profile per recipe
