E1101 – Proteases
Flour bleaching agentDescription
Mixture of proteolytic enzymes derived from animal (e.g., porcine pancreas), plant (e.g., papaya), or microbial (e.g., Bacillus subtilis fermentation) sources; purified and standardized for activity
Notes
Proteolytic enzymes are naturally occurring proteins that break down other proteins into smaller, more manageable pieces - think of them as molecular scissors specifically designed to cut protein chains. These enzymes can be extracted from animal sources (like the pancreas of pigs or cattle), plant sources (such as pineapple, papaya, or figs), or grown using beneficial microorganisms like bacteria or fungi in controlled laboratory conditions. The extraction process involves isolating and purifying these enzymes to create a concentrated mixture. In food production, these enzymes serve as powerful processing aids that help break down tough proteins to improve texture, tenderness, and digestibility. You'll find them working behind the scenes in meat tenderizers, cheese production (helping create the right texture and flavor development), baked goods (improving dough handling and bread texture), and protein-rich beverages (preventing cloudiness and improving clarity). They're also commonly used in brewing and wine-making to clarify the final product. The source of these enzymes matters significantly for consumers with specific dietary requirements. Animal-derived versions are not suitable for vegetarians or vegans, and may conflict with certain religious dietary laws. However, plant-based and microbial versions are widely available and suitable for most dietary restrictions. These enzymes are generally recognized as safe, though they're typically used in very small quantities and often removed or deactivated during processing.
