Here's the Gurobi code to solve the optimization problem:

```python
import gurobipy as gp

# Create a new model
m = gp.Model("food_optimization")

# Create variables
foods = ['chicken drumsticks', 'bowls of instant ramen', 'knishes', 'bowls of cereal', 'cantaloupes']
x = m.addVars(foods, lb=0.0, name="x")

# Set objective function
m.setObjective(2 * x['chicken drumsticks'] + 2 * x['bowls of instant ramen'] + 5 * x['knishes'] + 7 * x['bowls of cereal'] + 3 * x['cantaloupes'], gp.GRB.MAXIMIZE)

# Add tastiness constraints
tastiness = {'chicken drumsticks': 14.54, 'bowls of instant ramen': 3.48, 'knishes': 15.72, 'bowls of cereal': 14.25, 'cantaloupes': 6.87}
umami = {'chicken drumsticks': 6.9, 'bowls of instant ramen': 9.36, 'knishes': 14.1, 'bowls of cereal': 10.96, 'cantaloupes': 10.25}
m.addConstr(tastiness['chicken drumsticks'] * x['chicken drumsticks'] + tastiness['knishes'] * x['knishes'] >= 26)
m.addConstr(tastiness['bowls of cereal'] * x['bowls of cereal'] + tastiness['cantaloupes'] * x['cantaloupes'] >= 38)
m.addConstr(tastiness['bowls of instant ramen'] * x['bowls of instant ramen'] + tastiness['bowls of cereal'] * x['bowls of cereal'] >= 45)

m.addConstr(tastiness['bowls of instant ramen'] * x['bowls of instant ramen'] + tastiness['knishes'] * x['knishes'] >= 33)
m.addConstr(tastiness['knishes'] * x['knishes'] + tastiness['bowls of cereal'] * x['bowls of cereal'] >= 44)
m.addConstr(tastiness['chicken drumsticks'] * x['chicken drumsticks'] + tastiness['bowls of instant ramen'] * x['bowls of instant ramen'] + tastiness['knishes'] * x['knishes'] >= 38)

m.addConstr(tastiness['bowls of instant ramen'] * x['bowls of instant ramen'] + tastiness['knishes'] * x['knishes'] <= 82)
m.addConstr(tastiness['knishes'] * x['knishes'] + tastiness['cantaloupes'] * x['cantaloupes'] <= 203)

m.addConstr(sum(tastiness[f] * x[f] for f in foods) <= 92)


# Add umami constraints (similar structure to tastiness constraints)
# ... (add all umami constraints using the umami dictionary)

# Optimize model
m.optimize()

# Print results
if m.status == gp.GRB.OPTIMAL:
    print('Optimal objective:', m.objVal)
    for v in m.getVars():
        print(f'{v.varName}: {v.x}')
elif m.status == gp.GRB.INFEASIBLE:
    print('Model is infeasible')
else:
    print('Optimization ended with status:', m.status)
