उत्तर
Adding ethanol during cooling
Explanation:
The hydrolysate of sucrose refers to the solution obtained by breaking down sucrose (a disaccharide) into its constituent monosaccharides, glucose and fructose, through hydrolysis. Glucose is then separated from fructose by adding ethanol during cooling. Glucose, being almost insoluble in alcohol, crystallises out first.
