<p>This invention is based on the discovery that there is a relationship between the fouling rate of milk during processing into milk powder products and the β-lactoglobulin phenotype of the cow whose milk is being processed. Milk from β-lactoglobulin BB phenotype cows has a much lower fouling rate than that from β-lactoglobulin AA phenotype cows. The invention consists in a method comprising testing milk from identified cows for the presence of non-fouling β-lactoglobulin variants and recovering and maintaining that milk separate from the fouling variant containing milk. The non-fouling variant or blends of at least 30 % by weight of the non-fouling variant are further processed into milk powder products. The invention also consists in a method of selecting a diary herd having only β-lactoglobulin non-fouling variant phenotype cows.</p> |
