Muscle egg is pasteurized egg whites. I haven't seen their ingredient label though.
Egg Beaters contains Egg Whites, Less than 1%: Natural Flavor, Color (Includes Beta Carotene), Spices, Salt, Onion Powder, Vegetable Gums (Xanthan Gum, Guar Gum), Maltodextrin. Vitamins and Minerals: Calcium Sulfate, Iron (Ferric Phosphate), Vitamin E (Alpha Tocopherol Acetate), Zinc Sulfate, Calcium Pantothenate, Vitamin B12, Vitamin B2 (Riboflavin), Vitamin B1 (Thiamine Mononitrate), Vitamin B6 (Pyridoxine Hydrochloride), Folic Acid, Biotin, Vitamin D3
so screw that.
How come you don't like egg whites? Toss in some cheese/ seasoning / veg like spinach or my favorite those microwavable packages of broccoli with cheese sauce.
