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.
