The enzyme glucose oxidase is used commercially to remove glucose from dehydrated egg to improve colour, flavour, and shelf life. The reaction is: C,H12O6 +O2 + H2O→ C,H12O7 + H;O2 (glucose) (gluconic acid) A continuous-flow reactor is set up using immobilised enzyme beads that are retained inside the vessel. Dehydrated egg slurry containing 2% glucose, 20% water, and the remainder unreactive egg solids is available at a rate of 3000 kg h¯³. Air is pumped through the reactor contents so that 18 kg oxygen are delivered per hour. The desired glucose level in the dehydrated egg product leaving the enzyme reactor is 0.2%. Determine: (a) Which is the limiting substrate (b) The percentage excess substrate/s (c) The composition of the reactor off-gas (d) The composition of the final egg product
