DATA AND RESULTS 1 The gelatin occur because the gelatin is dissolved in water when heated and as the water cools, the molecules slow down and start bonding to weak hydrogen ions on the gelatin chains. Because of its fine grain it will dissolve too much into the steak and make it too salty. Enzymes are heat activated at levels between 140 F and 175 F and deactivated at the boiling point, so it serves no purpose other than flavoring to let the meat sit in a marinade at room temperature. * Pineapple Protease enzyme ( bromelain ) Breaks down or digests proteins.
