Researchers at Kuban State Agrarian University have unveiled a fast and affordable method to detect milk allergens, paving the way for healthier herds that produce hypoallergenic milk. This development was shared with socialbites.ca by the Priority 2030 program through the Ministry of Education and Science.
Milk intolerance often traces back to casein protein, a concern that manifests in two variants: A1 and A2. Milk containing the A2 form tends to be kinder to consumers who experience sensitivities, while A1 can trigger adverse reactions. The presence of either variant in milk is determined by the cow’s genetic makeup.
Scientists at KubGAU have created a rapid genetic test that distinguishes between the two casein types in cow milk with minimal material and without high costs. The technique is designed to deliver clear, actionable results quickly, enabling dairy producers to identify which cows carry the favorable A2 casein variant.
A small sample of genetic material suffices for a precise readout. In practical terms, a DNA fragment from a milk sample can reveal whether the milk contains the allergenic A1 variant. The complete analysis requires as little as 20 to 60 minutes, according to validating statements from KubGAU researchers.
The new testing approach makes it feasible to assemble herds tailored to produce hypoallergenic milk, even with a limited number of animals. This capability holds promise for farmers seeking to offer products that may be better tolerated by a broader segment of consumers who struggle with dairy allergies.
The advantages reported by the KubGAU team extend beyond speed. The method emphasizes laboratory sterility, relies on an automatic data capture system, and imposes fewer interpretive demands on technicians. By eliminating several time-consuming phases of traditional testing, the new approach also reduces the likelihood of erroneous readings and false positives, according to the university’s vice-rector for research, and senior researchers involved in the project.
The work aligns with the strategic initiative Genetics and Selection in livestock and crop production, part of the Priority 2030 program aimed at advancing scientific breakthroughs in Russia. The project reflects a broader push to integrate genetics with practical farming solutions, offering farmers a way to improve product quality while supporting consumer health and safety.
