Question

With the _____ in temperature and _____ in ice percentage, the percentage of soluble solids _____

(a) Increase, decrease, increases

(b) Decrease, increase, decreases

(c) Increase, decrease, decreases

(d) Decrease, increase, increases

The question was posed to me at a job interview.

Query is from Principles of Food Preservation by Drying-1 in chapter Principles of Food Preservation by Canning and Drying and Principles of Food Concentrates of Food Engineering

Answer 1

Right choice is (d) Decrease, increase, increases

For explanation I would say: With the decrease in temperature, majority of water converts into ice, hence, the ice percentage increases. Since the percentage of soluble solids is with respect to water and the water content has decreased and the solid concentration is constant, the percentage of soluble solids increases.
