Basic Information

• Common Name: Egg White (from Grade A, Large Eggs)
• Scientific Name: Albumen from Gallus gallus domesticus (Domestic Chicken Egg)
• Category: Animal Product

Varieties

Egg whites do not have varieties in the traditional sense, but they can come from different types of chicken eggs, such as conventional, free-range, organic, or those enriched with omega-3 fatty acids, which may slightly affect their nutritional profile.

Nutritional Information

• Macronutrients:
  • Carbohydrates: Minimal, about 2.36g per 100g (mainly in the form of simple sugars).
  • Proteins: High, approximately 10.7g per 100g. Egg whites contain all nine essential amino acids, making them a complete protein source.
  • Fats: Virtually fat-free, with less than 0.1g per 100g.
• Micronutrients:
  • Vitamins: Contains riboflavin (Vitamin B2) and niacin (Vitamin B3) but in smaller amounts compared to the whole egg.
  • Minerals: Rich in selenium, and also provides sodium, potassium, and magnesium.

Phytonutrients

Egg whites, especially from Grade A, Large eggs, primarily consist of water and protein and do not contain phytonutrients in the way that plant-based foods do. Phytonutrients are compounds found in plants that have various health benefits. While egg whites lack these specific nutrients, they are rich in high-quality proteins and contain several important vitamins and minerals. Here’s an overview of the nutritional components found in egg whites that contribute to their health benefits:

Proteins

• High-Quality Proteins: Egg whites are an excellent source of complete protein, meaning they contain all nine essential amino acids in the right proportions necessary for the body’s health.

Vitamins

• Riboflavin (Vitamin B2): Important for energy production, skin health, and eye health.
• Niacin (Vitamin B3): Supports the digestive system, skin, and nerves, and is also important for converting food to energy.

Minerals

• Selenium: A powerful antioxidant that plays a critical role in DNA synthesis, reproduction, thyroid hormone metabolism, and protection from infection and oxidative damage.
• Potassium: Essential for proper cell function, nerve transmission, and muscle contraction.
• Sodium: While generally low in egg whites, it’s necessary in small amounts for fluid balance, nerve transmission, and muscle function.
• Magnesium: Involved in over 300 biochemical reactions in the body, including protein synthesis, muscle and nerve function, blood glucose control, and blood pressure regulation.

While egg whites do not contain phytonutrients, their high protein content and presence of essential vitamins and minerals make them a valuable component of a nutritious diet. They provide key nutrients necessary for muscle repair, immune function, and overall health, all while being low in calories and fat, making them especially beneficial for those looking to increase protein intake without adding significant calories or fat to their diet.

• Calorie Count: Low, about 52 calories per 100g.
• Glycemic Index: Non-applicable (NA) as it contains negligible carbohydrates.

Physical Characteristics

• Color: Translucent white, becomes opaque and firm when cooked.
• Shape: Liquid without a fixed shape, takes the form of its container.
• Size: One large egg white is approximately 30-33g.
• Texture: Viscous and slightly gelatinous when raw, varying from soft to firm when cooked, depending on the method.

Culinary Uses

• Common Dishes: Used in making meringues, soufflés, marshmallows, angel food cakes, and white omelets. Also used as a binding or leavening agent in baking.
• Preparation Methods: Can be whipped to incorporate air and increase volume for light, airy dishes. Cooked on its own or added to other dishes for added protein without the fat.
• Suitable Pairings: Complements both sweet and savory flavors. In sweet dishes, pairs well with sugar, vanilla, and cream of tartar (for stability when whipping). In savory dishes, works well with herbs, spices, and lean meats or vegetables.

Geographical Information

• Origin: Domesticated from the wild jungle fowl of Southeast Asia.
• Primary Growing Regions: Eggs are produced worldwide, with the top producers including China, the United States, India, Mexico, and Japan.
• Seasonal Availability: Egg whites, like whole eggs, are available year-round due to controlled egg production practices.

Egg whites from Grade A, Large eggs offer a high-protein, low-calorie option ideal for those monitoring fat intake or requiring high-volume, low-fat ingredients in culinary applications. Their versatility and nutritional profile make them a staple in both home kitchens and professional culinary settings.
