Sodium cyclamate

B
Sodium benzoate

C
Sodium acetate

D
Vanillin

Solution

Sodium benzoate is a preservative. As a food additive, sodium benzoate has the E number E-211. It is bacteriostatic and fungistatic under acidic conditions.

It is most widely used in acidic foods such as salad dressings (vinegar), carbonated drinks (carbonic acid), jams and fruit juices (citric acid), pickles (vinegar), and condiments.
Question 4

Which of the following is a mild tranquilizer?

A
Valium

B
Meprobamate

C
Bithional

D
Norethindrone

Solution

Meprobamate is a carbamate derivative, which is used as an anxiolytic drug. It was the best selling mild tranquilizer for a time, but has largely been replaced by benzodiazepines due to their lower toxicity and serious side effects.
Question 5
1 / -0

Aspartame is unstable at cooking temperature. Where would you suggest aspartame to be used for sweetening?

A
Soft drinks

B
Cold drinks

C
Both of them

D
None of these

Solution

Aspartame is unstable at cooking temperature, hence it can used in soft drinks and cold drinks for artificial sweetening.
Question 6
1 / -0

Four samples of arhar dal were taken in four test tubes with some water in each and
labelled P,Q, R and S. A few drops of the following were added to these test tubes,
water to test tube P, HCl to test tube Q, NaOH to test tube R and alcohol to test tube S.
We would be able to confirm adulteration of the dal with metanil yellow in test tubes :

A
Q

B
Q and R

C
R and S

D
S and P

Solution

Metanil yellow adulteration in foods can be identified upon addition of HCl to the solution.

As HCl with metanil yellow gives pink colour.

Therefore, the adulteration could be confirmed only in test tube Q.

Hence the correct option is A.
Question 7
1 / -0

Equanil is a/an _____

A
artificial sweetener

B
tranquilizer

C
antihistamine

D
antifertility drug

Solution

Equanil, also known as Meprobamate, is a tranquilizer.
Question 8
1 / -0

Detergents with branched hydrocarbon chains are less likely to be:

A
biodegradable

B
synthetic

C
sulfonates

D
effective

Solution

Detergents with branched hydrocarbon chains are less likely to be biodegradable, that is they are not broken down by the bacteria easily. Thus, they cause water and soil pollution. All the soaps, on the other hand, are biodegradable.
Question 9
1 / -0

Sugar is the main source of energy as it produces energy on metabolic decomposition. But these days low calorie drinks are more popular.

A
True

B
False

C
Ambiguous

D
None of these

Solution

Natural sweeteners e.g, sucrose add to calorie intake. Due to the occurrence of more cases of diabetes and obesity young and old people, these days people usually take low-calorie drinks. These are artificial sweetening agents as given below.

Saccharin: It is 550 times as sweet as cane sugar. It is excreted from the body through urine.
Aspartame: It is 100 times as sweet as cane sugar. Its use is limited to cold foods and soft drinks because it is unstable at cooking temperature.
Alitame: It is more stable than aspartame but the control of sweetness of food is difficult while using it.
Sucralose: It is stable at cooking temperature. It does not provide calories.

These artificial sweetening agents do not metabolize and hence do not produce any energy. So the statement is true.
Question 10
1 / -0

Asprin is an:

A
analgesic

B
antipyretic

C
antimalarial

D
both analgesic and antipyretic

Solution

Aspirin is used to treat mild to moderate pain and to reduce fever or inflammation. Hence, it is both an analgesic as well as an antipyretic. Therefore, option D is the right answer.
