Dragée Coating Weight: How Much Coating Each Layer Needs

A coating layer weighs its shell volume times its density, and shell volume grows with the cube of the radius. How to calculate layer and batch coating weight for a dragée, with a worked sphere example.

Caramel Glass Transition: How Moisture Sets Texture

Why a few points of water move a caramel from hard crack to chewy: the glass transition, a Gordon–Taylor table you can recompute, and the water left at each cooking stage.

Pectin Gelation: pH, Brix and Dose for a Firm Set

Why an HM pectin gel sets, sets weak or fails: the pH and soluble-solids window, the dose, rapid vs slow set, and how to fix a weak or weeping pâte de fruit.

Sugar Types in Confectionery: Which Sugar Does What

Sucrose, glucose syrup, dextrose, fructose, invert sugar, lactose and trehalose compared: which sugar to use in caramel, ganache, fondant, pâte de fruit, ice cream, panning and nougat, and why.

Q10 and Arrhenius: How Storage Temperature Shortens Shelf Life

Estimate how a change in storage temperature changes confectionery shelf life with the Q10 rule and the Arrhenius equation, work through an accelerated shelf-life test, and learn where both models stop being reliable.

Water Activity in Ganache: The Science Behind Shelf Life Prediction

How the Formul.io Ganache Calculator estimates water activity from a formulation's sugar, polyol, and alcohol composition to predict microbial shelf life — and how to use those numbers responsibly.

Gelato vs. Ice Cream: Formulation Science Explained

Fat content, overrun, PAC/POD targets, and stabilizer strategy diverge sharply between gelato and ice cream. Understanding why each lever differs is the foundation of formulating either product correctly.
