UPSC Civil Services Model Paper 8

Natural sweeteners, e.g. sucrose add to calorie intake and therefore many people prefer to use artificial sweeteners.
Ortho-sulphobenzimide , also called saccharin , is the first popular artificial sweetening agent. Hence, Statement 1 is correct.
It has been used as a sweetening agent ever since it was discovered in 1879 .
It is about 550 times as sweet as cane sugar.
It is excreted from the body in the urine unchanged.
It appears to be entirely inert and harmless when taken. Its use is of great value to diabetic persons and people who need to control the 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 , although it is more stable than aspartame , the control of sweetness of food is difficult while using it. Hence statement 2 is correct.
Sucralose is a trichloro derivative of sucrose.
Its appearance and taste are like sugar .
It is stable at cooking temperature.
It does not provide calories.
Food preservatives prevent spoilage of food due to microbial growth.
The most commonly used preservatives include table salt, sugar, vegetable oils, and sodium benzoate, C6H5COONa.
Sodium benzoate is used in limited quantities and is metabolized in the body.
Salts of sorbic acid and propanoic acid are also used as preservatives.
