   Which of the following artificial sweeteners has the highest sweetness value in comparison to cane sugar?
   1. A.Aspartame
   2. B.Sucralose
   3. C.Alitame
   4. D.Saccharin
   Show answer & solution

   Answer: (C)

   Saccharin, also called ortho-sulphobenzimide, is the first popular artificial sweetening agent. It is about 550 times as sweet as cane sugar. Its use is of great value to diabetic persons and people who need to control their intake of calories. Aspartame is the most successful and widely used artificial sweetener. It is roughly 100 times as sweet as cane sugar. It is the methyl ester of dipeptide formed from aspartic acid and phenylalanine. Use of aspartame is limited to cold foods and soft drinks because it is unstable at cooking temperature. Alitame is a high-potency sweetener, and it is roughly 2000 times as sweet as cane sugar. Sucralose is trichloro derivative of sucrose. Its appearance and taste are like sugar. It is roughly 600 times as sweet as cane sugar. So, sweetness value order with respect to cane sugar is: Alitame > Sucralose > Saccharin > Aspartame
