Dough and Pasty

Pasty materials play a key role in many industrial sectors. Neither liquid nor solid, they are characterized by an intermediate consistency and unique mechanical behaviors: plastic deformation, high viscosity, slow flow, and adhesion to surfaces. Mastering them is crucial to ensuring the quality, shaping, and performance of finished products.

At Rheonis, we provide unique insight into the properties, structuring and dynamics of pasta – from their formulation to their industrialization.

Measuring dough and pasty products

Pastes and pasty products require a multi-physical and multi-scale approach to understand their behavior:

• Rheology and viscoelasticity (flow, threshold stress, plasticity).
• Texture and consistency (penetration, hardness, spreading, cohesion).
• Adhesion and friction (tribology, bonding, detachment).
• Stability and homogeneity (sedimentation, segregation, compaction).
• Structural analysis (microscopy, permeability, porosity).

Industrial applications

Pasty materials are used in a wide variety of sectors:

• Food : pasta, fruit pastes, stuffings, chocolate or spreadable pastes.
• Cosmetics and care : creams, masks, toothpastes, pasty makeup.
• Pharmaceutical : ointments, pasty gels, filling or dental pastes.
• Materials : ceramic pastes, polymer pastes, conductive or adhesive pastes, mineral pastes for construction.
• Industrial processes : extrusion of technical pastes, 3D pasty printing, controlled deposition.
