Method for preparing gelatin hydrolysate with decreased endotoxin content
The patent application (Publication Number: US20240034909A1) describes a gelatin hydrolysate composition with specific characteristics. The composition has an endotoxin content of 20 EU/g gelatin hydrolysate or less, a molecular weight of 30 kDa or less, and is free of surfactant and enzyme. Subsequent claims detail variations of the gelatin hydrolysate, such as lower endotoxin content levels (10 EU/g or less, 4 EU/g or less, 2 EU/g or less, and 1 EU/g or less) and different molecular weight thresholds (20 kDa or less, 10 kDa or less, and 4 kDa or less).
Furthermore, the patent application outlines a method for obtaining the gelatin hydrolysate, involving specific incubation conditions (temperature of 80-96°C, pH of 3.5 or less) for a defined time period (at least 15 minutes). The method aims to reduce the endotoxin content of the gelatin hydrolysate. Additional variations in the method include lower pH levels (3.0 or less, 2.7 or less) and longer incubation times (30 minutes or more, 1-5 hours). Importantly, the process does not involve enzymatic treatment and specifies that no surfactant should be added during the production steps. The patent application emphasizes the importance of these specific characteristics and methods in producing gelatin hydrolysate with reduced endotoxin content and tailored molecular weight profiles.
