Give reason for each of the following:
Gelatin is added to icecreams.

Explanation

### Step-by-Step Solution:

1. **Understanding Gelatin**: Gelatin is a protein derived from collagen, which is found in animal connective tissues. It is commonly used in food products for its gelling properties.

2. **Role of Gelatin in Ice Cream**: Ice cream is a colloidal mixture, which means it consists of tiny droplets of fat dispersed in a liquid (water and sugar solution). The stability of this colloidal system is crucial for the texture and quality of the ice cream.

3. **Emulsifying Properties**: Gelatin acts as an emulsifier. Emulsifiers help to stabilize mixtures that would otherwise separate, such as oil and water. In ice cream, gelatin helps to keep the fat droplets evenly distributed throughout the mixture.
