Patent No. EP3437481 (titled "Yogurt Production Method") was filed by Ajinomoto on Mar 29, 2017. The application was issued on Sep 22, 2021.
A method to produce low-fat, low-protein yogurt with improved texture, reduced syneresis, and better shape retention compared to regular low-fat, low-protein yogurts. The method involves adding a protein glutaminase enzyme and starch to the raw milk during yogurt production. The protein glutaminase enzyme deamidates the milk proteins to improve mouthfeel and reduce sourness. The starch helps thicken the yogurt and reduce syneresis. By using lower fat and protein milk, the resulting yogurt has reduced fat and protein content.

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.
The dossier documents provide a comprehensive record of the patent's prosecution history - including filings, correspondence, and decisions made by patent offices - and are crucial for understanding the patent's legal journey and any challenges it may have faced during examination.
