There are far to many variables to make a true accurate answer, this is coming from a medical responder BUT lots of texts say about 120 min....but that's very much debatable
Enzymes and acidic juices in the stomach, which break proteins down into smaller molecules, is known as proteolytic enzyme.
Proteolytic enzyme (also known as protease) is any group of enzymes that break down the long chainlike proteins molecules into smaller molecules (peptides) and later into amino acids. In the stomach, protein digestion takes place. The three main proteolytic enzymes; pepsin (produced by the stomach), and trypsin and chymotrypsin (produced by the pancreas) breaks down proteins into polypeptides which are eventually broken down into amino acids by several exopeptidases and dipeptidases.
