Patent No. EP3813548 (titled "Acidic Beta-Lactoglobulin Beverage Preparation") was filed by Arla Foods Amba on Jun 26, 2019. The application was issued on Sep 17, 2025.
This packaged, heat-treated beverage preparation features a pH between 2.0 and 4.7 and a total protein content of 2% to 45% w/w, where at least 90% w/w of the protein is beta-lactoglobulin (BLG). The preparation is at least pasteurized and may optionally include sweeteners, sugar polymers, and/or flavor. To ensure improved organoleptic properties, such as low viscosity and reduced astringency, the protein fraction must exhibit an intrinsic tryptophan fluorescence emission ratio (I330nm/I350nm) of at least 1.11 and/or the beverage must have a protein denaturation degree of at most 10%. The invention provides a stable, high-protein acidic beverage that can be either transparent or opaque and is suitable for use as a dietary supplement or for treating protein malabsorption diseases.

Patent oppositions filed by competitors challenge the validity of a granted patent. These oppositions are typically based on claims of prior art, lack of novelty, or non-obviousness. They are a key part of the process for determining a patent's strength and enforceability.
