Chocolate, Confectionery & Sweet Spreads
Formulation, texture and stability in chocolate and confectionery
Taste and texture in chocolate and confectionery depend on rheology, fat crystallization, particle distribution and moisture management.
We develop formulations and adapt them to manufacturing conditions, distinguishing chocolate, fat-based spreads, gelled sweets and aerated products: each has its own structure and process.

Product families
Different systems of fat, sugar, water and air — and the technical considerations specific to each.
- 01
Chocolate tablets & bars
Dark, milk and white chocolate, with or without inclusions. Cocoa solids, fat, particle-size distribution, sensory melt and crystallization.
- 02
Coatings & molded chocolate
Chocolate and compound coatings, enrobing, molding and panning. Viscosity, shell thickness and setting; compound fats do not necessarily require cocoa-butter tempering.
- 03
Filled chocolates & bonbons
Praline, ganache, wet and fat-based fillings. Water activity, moisture and fat migration, filling–shell compatibility and interface stability.
- 04
Sugar-reduced & special-composition chocolate
Bulk sweeteners and polyols, protein or fiber enrichment. Rheology, particle size, sweetness and aftertaste; nutrition labeling and health claims require regulatory review.
- 05
Chocolate & nut-based spreads
Cocoa and hazelnut spreads with a continuous fat phase. Fat composition, oil separation, gritty or waxy texture, particle size and the fat-crystal network.
- 06
Nougat, turron, halva & nut sweets
Aerated, sugar-based or fat-based structures, not one shared process. Protein function, sugar crystallization, oils and solids are considered for each product type.
- 07
Gummies & gelled confectionery
Gelatin, pectin and alternatives. Acidity, Brix and solids, gel texture, stickiness, syneresis and drying appropriate to the system.
- 08
Marshmallow & aerated confectionery
Foam formation and air incorporation, proteins and hydrocolloids, moisture and shape retention during processing and storage.
Technical challenges
What do we investigate when texture, appearance or processing behavior changes?
White coating, dullness or bloom on chocolate?
Distinguish fat bloom from sugar bloom. Check temper, fat migration from fillings, humidity and storage-temperature fluctuations — not temper alone.
Too thick to pump, mold or enrobe?
Review particle distribution, fat, emulsifiers, refining and conching conditions, and flow at the operating temperature.
Grainy or waxy mouthfeel, or poor snap?
Check particle size and distribution, fat profile, crystallization and sensory melting behavior.
Does a spread separate oil or become grainy?
Examine liquid fat versus the crystal network, solids concentration, mixing and storage-temperature history.
Do fillings soften shells, separate or change?
Check moisture and water activity, fat migration and filling compatibility with the chocolate or coating over storage.
Does sugar replacement change texture and processing?
Review bulking agents, viscosity, solids balance, aftertaste and crystallization; substitution is not simply matching sweetness.
Do gummies weep, stick, crystallize or fail to set?
Check the gelling system, acidity, solids, sugar crystallization, drying and water management.
Does marshmallow foam collapse or fail at scale?
Review whipping and air incorporation, proteins and hydrocolloids, temperature, solids and shear in the actual equipment.
Processes & technologies
Work is selected for the matrix and product. Tempering, sugar cooking, gel formation and whipping are not common stages for the whole category.
- 01
Ingredients & system balance
Raw-material selection and fat, solids and water balance for the intended structure.
- 02
Refining, conching & mixing
Particle size, dispersion and flow; sequence and equipment adapted to the product.
- 03
Tempering, molding & enrobing
Pre-crystallization, molds, coating and setting — only where relevant to the system.
- 04
Fillings, ganache & spreads
Emulsion development where needed, and control of separation and oil or moisture migration.
- 05
Sugar cooking, gels & aeration
Cooking conditions, gel formation and air incorporation suited to the confectionery matrix.
- 06
Cooling, packaging & scale-up
Storage, pilot planning and support, and validation under the specific process conditions.
From lab to production
Different refining, tempering, pumping, cooling or filling conditions can change texture and stability at scale. We review formulation, ingredients, equipment and parameters together.
Depending on the project, trials and pilots are prepared with manufacturing partners. Safety and shelf life need validation for the actual system, packaging and storage conditions.
