Answer 1

Correct Answer: 04 : 02 : 01

Rationale:

When preparing an emulsion, the correct ratio of oil, water, and gum is crucial to ensure stability and proper emulsification.
For Cod liver oil emulsions, the standard ratio used is 4 parts oil to 2 parts water to 1 part gum. This ratio helps to form a stable emulsion where the oil is evenly dispersed in the water phase.
The gum acts as an emulsifying agent, facilitating the mixing of oil and water by lowering the surface tension between the two immiscible liquids.

Explanation of Other Options:

02 : 02 : 01

Rationale: This ratio provides equal parts of oil and water with gum, which is not sufficient to create a stable emulsion for cod liver oil. A higher amount of oil is typically required.

01 : 02 : 01

Rationale: This ratio indicates more water compared to oil, which can lead to an unstable emulsion. For cod liver oil, the oil component should be more than the water component for proper emulsification.

03 : 02 : 01

Rationale: Although this ratio is closer, it still does not match the optimal ratio of 4:2:1, which is recommended for the stable and efficient preparation of cod liver oil emulsions.

Conclusion:

For the preparation of cod liver oil emulsion, using the ratio of 4 parts oil to 2 parts water to 1 part gum ensures a stable emulsion. Therefore, the correct answer is 04 : 02 : 01.
