- The liver produces bile, which is stored in the gall bladder before being released into the small intestine. Bile neutralises the acid that was added to food in the stomach. This provides alkaline conditions in which enzymes in the small intestine work most effectively
- Some microorganisms produce enzymes that pass out of the cells. These enzymes have many uses in the home and in industry. In the home:
■ biological detergents may contain protein-digesting and fat-digesting enzymes (proteases and lipases)
■ biological detergents are more effective at low temperatures than other types of detergents. In industry:
■ proteases are used to ‘pre-digest’ the protein in some baby foods
■ carbohydrases are used to convert starch into sugar syrup
■ isomerase is used to convert glucose syrup into fructose syrup, which is much sweeter and therefore can be used in smaller quantities in slimming foods.
