That’s not pure gelatin though. It’s a mix of gelatin from the breakdown of proteins, and juices from the chicken. Great for your cat without a doubt, and absolutely worth putting in home made soups or stews, but not something you’d want to use to make a wobbly dessert! Getting pure gelatin (i.e. all broken down peptides and virtually no remaining muscle protein) takes either days of careful boiling and straining, or a controlled industrial-chemical process. Gelatin was a fancy-chef ingredient when it took days in the kitchen to produce it with relative purity, but now you can buy Jell-O powder with pocket change because we make gelatin at scale using an industrial process.
