Preservatives
Preservatives are substances used in the beverage industry to keep drinks fresh and safe for longer periods. They help prevent the growth of harmful bacteria, mold, and yeast that could spoil the product. Think of them as protective ingredients that extend the shelf life of drinks while maintaining their taste and quality. Some common types include natural preservatives (like citric acid from citrus fruits) and synthetic preservatives (like potassium sorbate). When you see this term in resumes, it usually indicates experience with food safety, quality control, or product development in beverage manufacturing.
