Consistency analysis

Introduction

Consistency is an essential sensory and physicochemical property for semi-solid or pasty products. It directly influences sensory perception, the final use of the product, and its compliance with quality specifications. Measuring consistency allows for the control of a product's texture, stability, and homogeneity at different stages of its formulation or life cycle.

Objective of the analysis

Consistency analysis aims to:

• Evaluate the texture or firmness of a product
• Compare resistance to deformation or spreading
• Optimize formulations according to consumer preferences or industrial requirements
• Check the reproducibility of batches in production
• Meet standards specific to certain products (dairy products, cosmetics, pastries, etc.)

Analytical techniques used

• Penetration by cone or probe: measurement of the depth of penetration
• Compression or extrusion test: resistance to controlled pressure
• Shear test: force required to deform a pasty product
• Texture Profile Analysis: force vs. deformation curves

Depending on the matrices, the parameters measured may include: firmness, adhesiveness, cohesion, apparent consistency, elasticity, etc.

Analyzed matrices

• Food products: yogurts, purees, spreads, jams
• Cosmetics: creams, gels, body lotions
• Pasty or semi-solid pharmaceutical products
• Muds, waxes, clays, technical or industrial pastes

Industrial applications

• R&D: adjusting formulas to achieve a target consistency
• Quality control: monitoring of consistency between batches
• Sensory marketing: optimizing perception in the mouth or by touch
• Regulation: verification of normative criteria (e.g. dairy products, baby food)
