Egg Whites

Egg white products come as liquid pasteurized egg whites, powdered egg white (dried), and concentrated or frozen liquid forms. Liquid pasteurized is ready-to-use for cooking and baking, powdered is shelf-stable and reconstitutes with water, and frozen or concentrated liquids offer bulk portions often used by foodservice or frequent bakers

For baking, choose liquid pasteurized or powdered egg whites that specify culinary use to ensure consistent volume and foaming; for protein supplementation, look for products with nutrition labels showing grams of protein per serving and minimal added sugars or flavors, such as unflavored powders or pure liquid whites

Check protein per serving, calorie and sodium content, presence of additives (salt, stabilizers, anti-caking agents), allergen statements, and whether the product is pasteurized; for powdered forms, review reconstitution instructions and any added flavorings or sweeteners

Powdered egg whites are pasteurized during processing and are shelf-stable when unopened, making them convenient for storage and travel; they require rehydration and may perform slightly differently in foaming or texture compared with fresh or liquid pasteurized whites, so follow package reconstitution ratios for best results

Store unopened powdered egg whites in a cool, dry place; after opening, keep them tightly sealed and use by the manufacturer's recommended timeframe. Liquid or frozen egg whites should be refrigerated or kept frozen according to package instructions and used within the stated refrigerated shelf life once opened or thawed

Egg whites contain no yolk but are an egg-derived product and are not suitable for people with egg allergies; review labels for cross-contamination warnings if you have additional allergies, and check for certifications such as gluten-free if you have a gluten sensitivity

Prices vary by form and brand: powdered and bulk liquid concentrates often cost less per serving than small retail liquid cartons, while specialty formulations (organic, specialty packaging, or added nutrients) increase cost. Shoppers should expect a broad range, with average category prices influenced by package size and brand positioning
