Subtopic: Processing of seeds, spices, fruits and vegetables
Question Statement:
Potatoes are dried from 14% to 93% total solids. Considering 8% peeling losses, the product yield from one tonne of raw potato will be
Options:
(A) 10.56%
(B) 13.85%
(C) 15.25%
(D) 20.58%
Official Answer Key:
B
Step-by-Step Solution & Explanation
For 1000 kg raw potato (14% total solids), mass of solids = 1000×0.14 = 140 kg. After 8% peeling loss (mass reduced, solids concentration in the remaining potato unchanged), solids retained after peeling = (1000×0.92)×0.14 = 128.8 kg (equivalently 140×0.92). Final dried product at 93% solids: mass = 128.8/0.93 = 138.5 kg. Yield = 138.5/1000×100 = 13.85%.
