In the modern dairy industry, product quality control is becoming increasingly important. One of the key components attracting particular attention from manufacturers and laboratories is lactoferrin — a natural protein found in mammalian milk that plays an important role in immune support, iron metabolism, and gut health. Lactoferrin is especially important in infant nutrition, which is why bovine lactoferrin is often added to infant formula to bring its composition closer to that of human breast milk. However, the importance of this protein extends far beyond infant nutrition. Lactoferrin is naturally present in many dairy products such as cheese, yogurt, and milk-based beverages. Therefore, accurate determination of its content is essential for product quality control, verification of manufacturer claims, and compliance with international standards. With the development of global food trade, compliance with international regulatory requirements is becoming increasingly important. In particular, GB 5009.299:2024 and AOAC Official Method 2021.10 establish requirements for the accurate determination of lactoferrin in food products. Compliance with these standards is essential for access to international markets and increasing consumer trust.
Solutions for accurate lactoferrin determination
For laboratories working with dairy products, it is important to use reliable analytical tools that ensure accurate and reproducible results. One such solution is EASI-BIND® LACTOFERRIN (https://biola.lviv.ua/products/easi-bind-lactoferrin-easi-bind-laktoferin-art-no-rbrp700-5-rbrp700-25/) — a high-performance heparin affinity column specifically designed for the purification and quantification of lactoferrin in dairy matrices. This solution has been validated according to international standards and offers a number of important advantages. First, the system provides reliable analysis by effectively eliminating matrix effects, allowing accurate results even in complex products such as cheese, yogurt, or infant formula. Second, the columns have a reusable format — they can be used up to 10 times, making the analysis cost-effective for laboratories with high sample throughput. In addition, the solution fully complies with the requirements of official GB and AOAC methods, allowing it to be used for laboratory control in accordance with international standards. The 3 ml column format ensures stable and reliable performance even with the most complex dairy matrices, including infant formula.
Applications in the dairy industry
With the growing demand for functional and fortified dairy products, lactoferrin analysis is becoming increasingly important across various product categories. In cheese production, lactoferrin control allows verification of natural protein levels and compliance with manufacturer claims. For yogurt and fermented dairy products, analysis is particularly relevant when the product is positioned as functional or protein-enriched. In infant formula production, lactoferrin levels are strictly controlled, as they affect both regulatory compliance and nutritional value. The use of modern lactoferrin testing solutions enables manufacturers and laboratories to be confident that their products meet safety, quality, and international standards, while also supporting innovation in the dairy industry.
