Designer and Specialty Eggs

By –Akanksha Singh & Asif Ejaz

•  "Designer eggs" are those in which the content has been modified from the standard egg.

• Developed due to problems arising out of HIGH CHOLESTROL LEVEL and SALMONELLA.

• The concept was put forward by Dr. J. Sim of University of Alberta , N.A.

DESIGNER EGGS

Production of Designer EggsModifying egg quality

can be accomplished by:-

• inducing metabolic changes in the hen that can result in synthesis of compounds that essentially end up in her egg.

• change the characteristics of membrane transport to facilitate movement of compounds into the egg.

• modify egg quality is to manipulate the diet of the hen such that the desired compounds eventually find their way into the egg.

Nutrient Content • Vitamin content• Lowered Cholesterol• Fat content• Mineral content• Pigment content• Pharmaceutical content

Vitamin content• Depends on dietary concentration of

any specific vitamin.

• Have 26 times more Vitamin E.• Have 16 times higher CAROTENOID

content.• Have 7 times greater SELENIUM

content.• Have 6 times higher DHA content.

Lowered Cholesterol• Depends on diet and

Pharmacological Intervention.

• Drugs like PROBUCOL have lowered the egg cholesterol by 50 %.

• Such eggs have 29% less saturated fat.

• Other methods• -Chromium

supplementation.• -Lowering the

energy Consumption of hen.

Fat content• Depends on feed of

flaxseed ,marine algae ,fish oil and vegetable oil.

• Have higher amount of omega-3 fatty acid.

• High amount of Iodine.• Have lowered

saturated to unsaturated fatty acid ratio.

Mineral Content• Done by feeding diet

rich in zinc, copper, iodine, chromium and selenium content.

• Calcium and phosphorus content of the shell is enhanced in these eggs.

Pigment content• Depends on the dietary

concentration of any particular pigment.

• Consumer preferences vary greatly according to yolk color.

• pigmented yolks are used in bakery products , pasta and mayonnaise.

Pharmaceuticals • Produced by genetic

modification of chickens

• Compounds like Insulin and antibodies are being produced by this method

• Production of anti-venoms and protection from tooth decay.

• Alternative choices to consumers with special needs and preferences.

• Nutrient content of an egg can be changed only by altering the hen’s feed.

• Nutrient content cannot be altered by changing environmental conditions.

• Due to higher production costs, specialty eggs are usually more expensive than generic shell eggs.

Specialty Eggs

Types of Specialty Eggs

• Organic Eggs• Vegetarian Eggs• Aracauna Eggs• Pasteurized Shell Eggs• Fertile Eggs• Cage-Free Alternatives• United Egg Producers Certified

Eggs

Organic eggs• The National Organic Standard

Board (USDA)in October 2002 set national guidelines for producers.

• Produced by hens given feed grown without most conventional pesticides , fungicides, herbicides, or commercial fertilizers.

• Use of growth hormones and antibiotics is prohibited.

• Produced by free roaming hens with access to outdoors.

Vegetarian Eggs• Diet containing only

ingredients of plant origin.

• Nutrient content of these eggs is the same as that of regular eggs.

Aracauna Eggs• From Aracauna chickens, native to

South America.• Color -bluish-green eggs• Eggs from this breed have a higher

cholesterol content.• Nutritionally, not much different

from traditional white and brown eggs.

Pasteurized Shell Eggs• Heat treated to kill

potential salmonella bacteria found inside.

• Due to the heat processing, these eggs may have slightly lower levels of heat sensitive vitamins.

• Packaged in liquid, frozen or dried form.

• Used in recipes like home made ice-cream or in Caesar salad dressing.

Fertile Eggs• Some cultures consider

fertile eggs a delicacy.• no nutritional difference

between fertile eggs and generic eggs.

• Thoroughly cooking generic shell eggs destroy any potential salmonella bacteria in the egg.

Cage-Free Alternatives• housed in large laying

facilities that use cage systems.

• provides hens with optimal temperature, humidity, feed, water, laying space, and security.

• designed for the welfare of the birds as

well as for production efficiency.

• Alternative choices-• -Free-range eggs• -Cage-free eggs

United Egg Producers Certified Eggs• new animal welfare

standards that improve the care and handling of egg-laying hens.

• hens living in humane conditions with attention to living environment, health care, and treatment.

• Animal welfare and health were important factors considered in producing the eggs.
