COMMERCIAL USES OF ENZYMES Micro-encapsulation involves the enzyme being attached to an inert particle, like a resin bead. The beads are then packed into a vertical tube, which the substrate can then be poured down. Particular industries, which use this, are in the production of clear juices and glucose isomerase. The fruits in juices almost always contain pectins, which hold the fruit cells together. Due to this, juice can often appear cloudy, but pectinase is often added to fruit juice (apple juice) to make it appear clear. There are many disadvantages to leaving pectinase in the apple juice. For example, some people may be allergic to that particular enzyme; it is expensive to purify and extract the enzymes and it's also very time consuming. In addition the enzyme is wasted and cannot be used again. Consequently, the technique of enzyme immobilisation is used. The pectinase is embedded into resin beads, which...
