Fat content dosage

Fat content analysis is a reference analysis in food physicochemical analysis. It quantifies the total lipid content present in a solid or liquid sample. This measurement is essential for:

• Regulatory nutrition labelling
• Quality control of raw materials and finished products
• The formulation of functional, dietary or technical foods
• Monitoring manufacturing or extraction processes

The analysis applies to a wide range of matrices, from animal feed to processed plant products, including cosmetic creams and oils extracted from seeds.

Analytical methods used

Fat content measurement relies on various standardized techniques, selected according to the nature of the matrix:

• Soxhlet extraction: a reference solvent-based method (ether, hexane) allowing for precise quantification of extracted lipids
• Preliminary acid hydrolysis (Weibull-Stoldt method): used to release the fat fraction bound to the matrix (casein, starch, plant cell walls)
• Direct gravimetric method: for oily matrices or simple products
• The results are expressed as % of fat on raw or dry product, in accordance with current standards (ISO, AOAC, NF V03-701, etc.).

Types of matrices concerned

Fat content analyses can be performed on a wide range of industrial products:

• Animal feed (pellets, flours, extruded feed, forage)
• Plant-based ingredients (seed powders, oilseed cakes, legumes)
• Food products (biscuits, bars, sauces, pasta)
• Cosmetic products (creams, vegetable butters, waxes)
• Extracted products or edible oils (rapeseed, sunflower, soybean, etc.)

This service is also useful in the context of recycling or the treatment of organic waste, in order to know its lipid potential.

Industrial sectors concerned

Fat analysis is crucial for several sectors:

• Animal nutrition: formulation of balanced feeds, valorization of lipid-rich by-products
• Food industry: labeling compliance, fat reduction, nutritional enhancement
• Cosmetics: control of vegetable oil extracts, formulation of oil phases
• Plant/nutraceutical industry: evaluation of the lipid content of medicinal or functional plants

Recommended Related Analyses

For a complete characterization of fatty or oily products, you can combine this service with:

• Fatty acid analysis – for precise identification of lipid composition
• Peroxide value (fat oxidation) – to assess the stability of oils
• Vitamin E (tocopherol) dosage – often associated with the oil phase in plant extracts
• Analysis of antioxidant activity (DPPH, ORAC) – complementary for enriched or functional oils
