Egg Products
Processed and convenience forms of eggs for commercial, foodservice and home use. These are refrigerated liquid, frozen, dried and specialty products. Many egg products are comparable in flavor, nutritional value and most functional properties to shell eggs. Convenience foods such as cake and pudding mixes, pasta, ice cream, mayonnaise, candies and bakery goods utilize egg products. Egg products are frequently preferred to shell eggs by commercial bakers, food manufacturers and the foodservice industry because they have many advantages including convenience, labor savings, minimal storage requirements, ease of portion control, and product quality, stability and uniformity.
Surplus shell eggs, as well as those produced particularly for the purpose, are used in making eggs products. In 1992, about 20% of the total U.S. egg production went into egg products. About 3/4 billion pounds of all types of egg products are produced each year in the U.S.
Since passage of the Egg Product Inspection Act (EPIA) in 1970, all plants that make egg products operate under continuous USDA inspection. Under this Act, pasteurization of all egg products is mandatory.
Shell eggs used for egg products must be clean and of edible interior quality.
Processing egg products. When shell eggs are delivered to the breaking plant, they are put into refrigerated holding rooms. Before breaking, they are washed in water at least 20 degrees warmer than that of the egg and spray-rinsed with a sanitizing agent. They may be moist, but not wet, when they are broken.
Refrigerated liquid products Eggs are broken and separated, if necessary, by machines and the liquid egg put into covered containers. At this point, they may be shipped to bakeries or other outlets for immediate use or to other plants for further processing. Shipment is in sanitary tank trucks maintaining temperatures low enough to assure that the liquid egg arrives at its destination at 40ºF. (4ºC.) or less. Wholesale and food-service refrigerated products are also available in 30-pound cans and 4-, 5-, 8- and 10-pound cartons.
Retail consumer refrigerated products are generally available in one- or two-pack cartons containing 8 to 16 ounces each.
Keep liquid egg products under refrigeration. Shelf life can vary, so check the label of the products you are using. Once opened, use immediately.
Frozen egg products These include separated whites and yolks, whole eggs, blends of whole eggs and yolks or whole eggs and milk and these same blends of whole eggs and yolks or whole eggs and milk and these same blends with sugar, corn syrup or salt added. Salt or carbohydrates are sometimes added to yolks and whole eggs to prevent gelation during freezing. Frozen egg products are generally packed in 30-pound cans and in 4-, 5-, 8- and 10-pound pouches or waxed or plastic cartons. Some retail consumer products are available frozen in one- or two-pack cartons containing 8 to 16 ounces each.
Frozen egg products should be kept frozen or refrigerated until used. They should be thawed under refrigeration or under cold running water in unopened containers. After defrosting, they should be refrigerated and used within 3 days.
Dried or dehydrated egg products Known also as egg solids, these have been produced in the united States since 1930, but demand was minimal until World War II when production reached peak levels to meet military and lend-lease requirements. While quality of the early product was poor, it has now been greatly improved. Dried egg products are used in a wide number of convenience foods and in the foodservice industry. With the exception of some camping supply store, dried eggs are not available at present on the retail market. Dried eggs for foodservice use are sold in 6-ounce pouches, number 10 cans and 3-pound and 25-pound poly-packs. For commercial use, 25- and 50-pound boxes and 150-, 175- and 200-pound drums are available.
Unopened dried egg products should be stored in a cool (below 70ºF.), dry place away from light. Opened containers should be tightly sealed and refrigerated.
Specialty egg products Egg specialties processed for the foodservice industry include wet-pack and dry-pack pre-peeled hard-cooked eggs, either whole, wedged, sliced, chopped or pickled; long rolls of hard-cooked eggs; frozen omelets; egg patties; quiche and quiche mix; frozen French toast; frozen scrambled egg mix in boilable pouch; frozen fried eggs; frozen pre-cooked scrambled eggs; freeze-dried scrambled eggs and other convenience menu items.
In the near future, innovative egg products such as ultra-pasteurized liquid egg, free-flowing frozen egg pellets and modified atmosphere packaging for hard-cooked eggs are expected to become available.
Many specialty egg items are reaching the retail market as well including frozen omelets and mixes; frozen scrambled eggs, French toast and quiche; and specially coated shelf-stable hard-cooked eggs.
