Change any ingredient and instantly see how shelf life, water activity, and texture shift. No more mold surprises. No more failed batches. Know before you make.
Excel Can't Tell You If It Will Mold.
You adjust the cream ratio, you change the glucose — but you won't know if the shelf life changed until it's sitting in a box for two weeks.
Invisible Spoilage Risk
Your ganache looks perfect. But without knowing its water activity, you don't know if mold is two weeks away — or two months.
Shelf Life Guesswork
You write "14 days" on the label because that's what you've always done. Not because you calculated it. That gap is where problems happen.
Intuition Doesn't Scale
When the recipe lives in your head, it doesn't transfer to your team — and it can't be adapted, tested, or improved systematically.
Recipe Scaling Breaks Things
Doubling a recipe in Excel recalculates weight. It doesn't recalculate water activity, texture stability, or shelf life. Those change too.
What changes when you add 3% sorbitol
Change an Ingredient. See the Consequences.
Formul.io shows you what Excel cannot: what happens to shelf life, texture, and stability when you adjust your recipe.
Water Activity — Real Time
Every ingredient change instantly updates the water activity reading. See if your recipe is in the safe zone before you make a single gram.
Shelf Life Prediction
Get a concrete shelf life estimate — in days — based on your recipe's actual composition, not a rule of thumb.
Scale Without Breaking
Scale from 500g to 50kg and watch the water activity and texture metrics update with the quantities — not just the weights.
2,000+ Ingredients, Pre-Loaded
Every ingredient comes with food science data — Aw contribution, PAC, POD — ready to use without manual data entry.
Fat · Sugar · Water Balance
Visual breakdown of your recipe's critical ratios in real time. Spot imbalances before they become batch failures.
Production-Ready Tech Cards
Export a professional PDF spec sheet with all calculated parameters — ready for your team or your client.
Texture & Flow Prediction
Know if the ganache will be pipeable, spreadable, or too thick — before mixing a single ingredient.
Nutri-Score & Nutrition Label
Automatic EU-standard nutritional grading and label data — A to E — from your ingredient list.
Version History
Every tweak is saved. Compare any two versions side by side. Roll back to what worked.
Side-by-Side Comparison
Stack two recipe versions and see exactly what changed — and what impact those changes had on stability.
Formulation Guidance, Not a Substitute for Testing
Formul.io predictions are based on established food science models — water activity theory, crystallization kinetics, and thermodynamics. Our calculations are within 5% of measured values, more accurate than manual estimates. For commercial production, verify critical safety parameters with calibrated instruments.
Always validate formulations through real-world testing before commercial production
Ensure compliance with your local food safety and labeling regulations
Results may vary based on ingredient quality, production equipment, and environment
Like USDA's Pathogen Modeling Program, we provide science-backed predictions to guide professional formulation decisions.
A Dedicated Tool for Every Confection
Each calculator is built around the specific science of its product — not a generic formula stretched to fit everything.
Ganache Studio
Complete ganache formulation: water activity, shelf life, rheology profiling, Nutri-Score, and batch scaling — all from one ingredient list.
Caramel Artisan
Caramel texture by cooking stage, crystallization risk, water activity, Brix, and sweetness balance — so you know what you're pouring before it sets.
Dragée Architect
Layer-by-layer formulation with 3D cross-section visualization, water activity per layer, and batch calculations for panning production.
Gelato Studio
POD/PAC balance, overrun, freezing point depression, and texture profiling — so your scoops are perfect from the first batch.
GelCraft Pro
Pectin gelation modeling, pH control, gel strength prediction, and shelf life optimization for fruit gels and pâtes de fruit.
Mousse Atelier
Aeration control, stability prediction, and texture profiling for mousses and bavarian creams that hold their structure.
Nougat Maestro
Aeration, crystallization management, and sugar system optimization for nougat and torrone that cuts cleanly every time.
The Questions Every Chocolatier Asks — Answered Before You Start
Not hypothetical. These are the exact situations where Formul.io changes the outcome.
Will It Hold at the Wedding?
Outdoor summer event at 30°C. Your usual ganache recipe works fine in the shop — but will it survive the heat without melting or blooming?
Adjust fat ratio and water activity in the calculator. See stability predictions at temperature before committing to a batch. Ship with confidence.
Can I Ship It Abroad?
Retail buyer wants 45-day shelf life. Your current recipe gives you 14. You don't know which ingredient to change — or if it's even possible.
Formul.io shows which parameters to move and by how much. Water activity optimization with the right sugar balance can extend shelf life without changing the flavor profile.
I'm Out of Invert Sugar — Now What?
Mid-production. You're out of invert sugar. Switching to glucose or honey changes water activity and crystallization risk in ways that are hard to eyeball.
Enter your substitution. Get the Aw and texture impact immediately. Know whether you can proceed — or if the batch needs adjusting first.
Tools for Every Stage of Formulation.
From single recipes to full production — choose the plan that fits your workflow.
Not a Spreadsheet. A Formulation System.
Every prediction is rooted in established food science: water activity models, crystallization kinetics, emulsion theory, and thermodynamics.
Peer-Reviewed Science
Water activity prediction, Clausius-Clapeyron shelf life models, and sugar crystallization theory — the same science your ingredients' manufacturers use.
Instant Consequence Modeling
Change one ingredient and see every downstream effect — shelf life, texture, water activity — update in real time. No waiting. No guessing.
Built for Real Work
8 calculators covering ganache, caramel, dragée, pâte de fruit, mousse, ice cream, nougat, and Recipe Forge. 20+ quality metrics per recipe. Works for a single bonbon or a 50kg production batch.
"I used to label everything '14 days' and hope for the best. Now I know the actual number before I make the first batch."
"Finally, I can tell my team WHY we use this ratio — not just 'that's how we've always done it.'"
