Ovotransferrin dosage

Ovotransferrin is a glycoprotein naturally present in egg white, belonging to the transferrin family. It plays a key role in antimicrobial defense by limiting the availability of iron necessary for the growth of microorganisms. Due to its functional properties, ovotransferrin is being studied and utilized in several fields, including the food industry, animal health, and nutraceutical formulations.

Ovotransferrin levels can be used to assess the nutritional and functional quality of egg products, as well as to verify the consistency of protein powders and ingredients used in dietary supplements. This analysis is also relevant for the development of formulations enriched with bioactive proteins, which may be beneficial for intestinal, immune, or antimicrobial health.

Analytical methods

Several approaches can be used to quantify ovotransferrin:

• The ELISA method, based on specific antibody recognition, is suitable for rapid and sensitive analyses. It is widely used in routine controls or research studies.
• High-performance liquid chromatography (HPLC) offers a complementary approach, enabling precise protein separation and reproducible quantification in complex matrices.

Both methods are reliable and can be chosen according to the type of matrix, the level of sensitivity required, and the objectives of the analysis.

Affected matrices

The ovotransferrin assay is applicable to different types of samples:

• Fresh or processed egg whites
• Egg-based protein powders
• Dietary supplements enriched with animal protein
• Innovative products incorporating bioactive ingredients derived from eggs

Industrial applications

Ovotransferrin analysis addresses several issues:

• Quality control of egg-based food products, in order to guarantee their nutritional value and biological activity.
• Development of nutraceutical formulations incorporating bioactive proteins recognized for their antimicrobial and immunomodulatory effects.
• Valorization of poultry industry co-products into high value-added functional ingredients.
• Animal health research, where ovotransferrin is studied as a nutritional indicator or as a functional molecule to enhance intestinal health in animals.

Additional analyses

Ovotransferrin testing can be complemented by other analyses available in the YesWeLab catalog, such as lysozyme testing (another bioactive egg protein), total protein testing, or free amino acid analysis. For food and nutraceutical formulations, it may also be beneficial to combine these analyses with lactoferrin testing, a glycoprotein with similar properties used in animal nutrition and health.

Regulations and quality

Analytical monitoring of bioactive proteins such as ovotransferrin helps meet the quality and traceability requirements set by European regulations. In the context of functional ingredient valorization, the standardization and precise quantification of these proteins are crucial for ensuring the safety and efficacy of finished products.
