It is translucent, colorless, and nearly tasteless powder. 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. From 140 degrees F and up, … These tenderizing enzymes also reduce the capability of the meat to hold its juices, resulting in greater fluid loss and thus drier meat.

Research question To what extent do varying temperatures (5°C, 55°C, 75°C, 100°C) affect the pH and the denaturation of gelatin in response to exposure to fruit enzymes, such as bromelain, papain, and amylases found in pineapple (Ananas comosus), * Pineapple Protease enzyme ( bromelain ) Breaks down or digests proteins. In addition to tenderizing meat, bromelain is used to "chill-proof" beer. 2 Gelatin also occur because one way to change the shape of enzyme is by heating (denaturation). In another experiment, students will look at how an enzyme in pineapple can break down the proteins that hold gelatin together. Prepared gelatin can be kept hot on a hot plate until ready for use.)
