Starch gelatinization analysis

Objective of the analysis

Starch gelatinization analysis allows us to characterize the thermal behavior of starches during their transition to an amorphous state under the influence of heat and humidity. This phenomenon strongly impacts the texture, digestibility, water absorption, and solubility of the matrices.

This analysis is essential for:

• Determine the gelatinization temperature and the associated energy (ΔH)
• Compare native and modified starches, or starches derived from different plant sources
• Optimizing industrial processes (cooking, extrusion, freeze-drying)
• Adapting technical or food formulations (hydrated products, soluble powders, animal feed)

Methodology

The sample (powder, extract or starch-containing formulation) is subjected to a controlled temperature increase via:

• Differential scanning calorimetry (DSC) : measurement of the heat flux absorbed during gelatinization
• Rapid Viscometric Analysis (RVA) : measurement of viscosity as a function of the thermal profile
• Optionally, microscopic observations can complement the analysis to visualize the loss of crystalline structure.

Additional tests may be offered depending on the objectives:

• Carbohydrate dosage
• Starch characterization 

Associated analytical techniques

• Differential scanning calorimetry (DSC)
• RVA Viscometric
• UV-Vis spectroscopy (in case of colorimetric complement)
• Microscopic observation (optional)

Examples of applications

• Quality control of flours and food starches
• Study of thermal stability in animal nutrition or nutraceutical formulations
• Functional comparison of processed plant-based ingredients
• Analysis of technological performance in food extrusions

At YesWeLab, we collaborate with a rigorously selected network of laboratories, most of which are certified and/or accredited (ISO 17025, COFRAC, etc.). These laboratories are chosen based on your specific needs, the matrices to be analyzed, and the required analytical techniques.

If you have specific requirements, please specify them in your request: our scientific team will assist you with precision and responsiveness.
Since 2020, numerous manufacturers, distributors, and formulators have entrusted us with the management of their analyses.
