Juice that is typically free from enzymes is pasteurized juice. The pasteurization process involves heating the juice to kill harmful microorganisms and also denatures enzymes, effectively rendering them inactive. As a result, pasteurized juices, such as those commonly found in stores, contain little to no active enzymes compared to fresh, unprocessed juices.
Amalyse
Pineapple juice is a good ingredient for a marinade because it contains the enzyme Bromelin which is a natural tenderiser.
pancreatic juice contains an enzyme called Tripsin present in our small intestine for the digestion of proteins into amino acids.
Jello does not solidify properly when mixed with fresh pineapple juice because it contains bromelain, an enzyme that breaks down the proteins in gelatin, preventing it from setting. However, canned pineapple juice is safe to use because the canning process deactivates the enzyme. Additionally, the acidity of pineapple juice does not interfere with gelatin setting, but it's the bromelain that is the primary concern. If you want to use fresh pineapple, you can heat it to deactivate the enzyme before mixing it with Jello.
Fresh pineapple juice contains the enzyme bromelain, which breaks down proteins. When added to gelatin, bromelain prevents the protein strands in the gelatin from forming a stable network, which is essential for the jello to set. In contrast, canned pineapple juice is safe to use because the canning process destroys the bromelain enzyme.
Pancreatic fluid is not an enzyme itself, but it contains many enzymes produced by the pancreas, such as amylase, lipase, and proteases. These enzymes are responsible for breaking down carbohydrates, fats, and proteins in the small intestine to aid in digestion.
pepsin
The enzyme present in intestinal juice is primarily intestinal lipase, which aids in the digestion of fats. Additionally, intestinal juice contains other enzymes such as maltase, sucrase, and lactase, which help in breaking down carbohydrates into simpler sugars. These enzymes play a crucial role in the final stages of digestion, allowing nutrients to be absorbed efficiently in the small intestine.
Enzyme that break down fatty acids are called lipases. Bile is a substance made in our liver which contains salts that breaks down fat into smaller droplets. The pancreas also contains a substance called pancreatic juice which contains numerous enzymes that work to break down things such as fat, protein and starch.
gastric juice
Grape Juice is a juice. It is not a carbohydrate, but it contains carbohydrates.
The substance that contains a starch-splitting enzyme is the pancreatic juice and saliva. The two types of enzymes that break down starch are pancreatic amylase and salivary amylase.
