Question

Fresh potatoes = 1000 kg, initial solids = 14%, final solids = 93%. Loss in peeling = 7%. Find product yield percent (integer).

Hint:

Total solids remain constant during drying processes.

Answer 1

Correct Answer: 14

Solids in fresh potatoes: \[ 1000 \times 0.14 = 140\ \text{kg} \] After peeling: \[ 1000 - 7% = 930\ \text{kg} \] Solids remain the same (140 kg). Final product mass: \[ M_f = \frac{140}{0.93} = 150.5\ \text{kg} \] Yield % relative to original 1000 kg: \[ Y = \frac{150.5}{1000} \times 100 = 15.05% \] \[ \boxed{15} \]
