Cholesterol Testing

Cholesterol is a steroid molecule found in animal cell membranes and plays a key role in lipid metabolism. While its excess is associated with cardiovascular risks, it is also essential for the synthesis of steroid hormones and vitamin D.

Cholesterol measurement is used to measure total cholesterol concentration in various types of matrices. It is used in food quality control, regulatory compliance verification and nutritional labeling, as well as in nutraceutical research and cosmetic formulation analysis.

Analytical principle

The analysis is based on standardized chromatography methods:

• GC-FID (gas chromatography with flame ionization detection) : applied after derivatization, it allows sensitive and specific quantification.
• HPLC (high performance liquid chromatography) : reliable alternative for the separation and measurement of complex lipid fractions.

These approaches guarantee the reproducibility and precision of results, in accordance with international standards.

Industrial applications

Cholesterol testing is essential in several sectors:

• Human nutrition : control of cholesterol levels in animal products (eggs, meat, dairy products).
• Nutraceuticals : characterization of lipid extracts or food supplements intended to regulate cholesterol.
• Animal nutrition : monitoring the lipid quality of enriched diets.
• Cosmetics : cholesterol dosage in formulations (creams, skin care).
• Plant research : analysis of plant extracts containing sterols or cholesterols.

Affected matrices

• Food products of animal origin (eggs, meat, dairy products)
• Food supplements and nutraceutical formulations
• Serum or animal biological matrices
• Lipid extracts and oils
• Cosmetic products (creams, treatments)

Quality and compliance issues

• Verification of cholesterol levels for regulatory nutrition labeling.
• Lipid profile monitoring for food and nutraceutical R&D.
• Quality control of cosmetic formulations containing sterols.
• Traceability and comparability of batches within a strict regulatory framework.
