Sample interview questions: Have you ever worked with materials for packaging or food preservation? If so, can you provide examples?
Sample answer:
- Yes, I have worked with materials for packaging or food preservation.
Examples:
- Modified atmosphere packaging (MAP): I have evaluated and selected polymeric materials for MAP applications. This involved a deep understanding of the interaction between the material’s properties and its influence on the shelf life and quality of the food product.
- Active packaging: I have developed novel materials for active packaging that can release specific gases or substances to extend the shelf life or improve the quality of food products. This required a comprehensive understanding of both materials science and food chemistry.
- Edible coatings: I have formulated and characterized edible coatings for food preservation. This entailed choosing appropriate biopolymers, understanding their interactions with food surfaces, and optimizing the coating process to ensure desired functionality.
