Gelatin which is a peptide is added in ice-creams. What can be its role ?

Explanation

**Step-by-Step Solution:**

1. **Understanding Gelatin**: Gelatin is a protein derived from collagen, which is found in animal connective tissues. It is a type of peptide and is known for its gelling properties.

2. **Role of Gelatin in Ice Cream**: In ice cream, gelatin serves primarily as an emulsifying agent. An emulsifying agent is a substance that helps to stabilize emulsions, which are mixtures of two immiscible liquids (like oil and water).

3. **Emulsification Process**: When making ice cream, the mixture contains water, fat, and air. These components can separate if not properly stabilized. Gelatin helps to form a barrier around the fat droplets, preventing them from coalescing (coming together) and separating from the water.
