Question

Varun’s mother added plenty of salt to the mango pickle she made. This is to:

• A. enhance the colour of the pickle.
• B. inhibit the growth of microorganisms.
• C. increase the nutritional value.
• D. create a hypertonic solution.

Hint:

Salt acts as a preservative by creating a hypertonic environment that inhibits the growth of microorganisms, which is why it is often used in pickling.

Answer 1

The Correct Option is B

Step 1: Understanding the role of salt in pickles.
Salt is commonly used in pickling because it acts as a preservative by drawing out moisture and creating a hypertonic environment. This inhibits the growth of microorganisms, allowing the pickle to last longer.
Step 2: Analyzing the options.
- (A) Enhance the colour of the pickle: While salt may affect the texture and preservation, it does not directly enhance the colour of the pickle. - (B) Inhibit the growth of microorganisms: Correct. Salt helps in creating a hostile environment for the growth of microorganisms by drawing out water, which preserves the pickle. - (C) Increase the nutritional value: Salt does not increase the nutritional value of the pickle; its main purpose is preservation. - (D) Create a hypertonic solution: Correct. Salt creates a hypertonic solution by drawing out water, which helps in preserving the pickle by reducing the possibility of microbial growth.
Step 3: Conclusion.
The correct answer is (B) and (D), as salt is primarily used to inhibit the growth of microorganisms and to create a hypertonic solution. Final Answer: (B) and (D).
