Question

To prevent food from spoilage by microorganism, which substance is used?
A. Amato
B. Aspartame
C. Salt of sorbic acid
D. Tetrazine

Answer 1

We know that food items and edible items like bread,cake, snacks and sweets get spoiled because of microorganisms,fungi, yeast and mold.It becomes important to use an organic antimicrobial agent which will prevent the food items from getting spoiled.

Complete step by step solution
As we know that to prevent food from spoilage by microorganisms we will use sorbic acid and its salts. Some of the salts of sorbic acids are sodium sorbate, potassium sorbate, and calcium sorbate. They are antimicrobial agents which prevent the growth of mold, yeast and fungi. For this reason sorbic acid and its salts are used as preservatives in food items.
The molecular formula of sorbic acid is ${C_6}{H_8}{O_2}$.
Tetrazine is used to colour food items, soft drinks and drugs. Aspartame is an artificial sweetening agent.
So from the above explanation and discussion it is clear to us that the correct answer of the given question is option: C. Salt of sorbic acid

Additional information:
Sorbic acid has a molar mass of $112.13g/mol$. It has a boiling point of $228^\circ C$.It is one of the most popular and common preservatives used in the entire world. Potassium sorbate is more soluble in water as compared to sorbic acid.

Note: always remember that sorbic acid and its salts are used to prevent food from spoilage. It kills lots of microorganisms which can cause fatal diseases. Sorbic acid has a molecular formula of ${C_6}{H_8}{O_2}$.According to studies and research it is proved that sorbic acid is not linked to cancer or other major health diseases.
