Flashcards

What is Food Science?

The study of food as a chemical system, including its composition, structure, and how it changes during processing and storage.

What are food preservation methods?

Methods used to extend the shelf life of foods and prevent spoilage. Examples include heating, freezing, drying, and using preservatives.

What are thermal preservation methods?

These methods involve applying heat to destroy microorganisms and enzymes that cause food spoilage.

What are non-thermal preservation methods?

These methods use techniques other than heat to preserve food. Examples include irradiation, high-pressure processing, and using natural antimicrobials.
