PROCESS TO REDUCE ENDOTOXIN IN GELATIN

The present disclosure is directed to processes for reducing the endotoxin level in gelatin and the resulting gelatin with low endotoxin content. The process includes dissolving a salt in a gelatin solution and filtering the gelatin-salt solution using anion exchange to reduce the endotoxin level. A...

Zusammenfassung:	The present disclosure is directed to processes for reducing the endotoxin level in gelatin and the resulting gelatin with low endotoxin content. The process includes dissolving a salt in a gelatin solution and filtering the gelatin-salt solution using anion exchange to reduce the endotoxin level. After reducing the endotoxin level of the gelatin-salt solution, the low endotoxin gelatin-salt solution is desalted to remove the salt, thereby producing a low endotoxin gelatin solution.
