3. PRO TIN PROTEIN

4. CARBOHYDRATE

5. VITAMINS

6. FOLATE

7. NUTRITIONA L VA L U E AND COMPONENTS OF EGG

8. UNLOCKING OF DIFFICULTIES LECITHIN – any of a group of phospholipids that are found in many plant and animal tissues, especially egg yolk.

9. CHALAZAE – One of a pair of spiral threads of albumen holding the yolk of a bird is egg in position. ALBUMEN – the white of an egg.

10. CHALKY – of or like chalk. CANDLING – to examine (eggs) freshness and fertility by holding them up to a bright light.

11. ENERGY VALUE OF EGGS

12. PROTEIN Eggs are excellent source of protein. Egg protein is of high biological value and as it contains all the essential amino acids needed by the human body.

13. VITAMINS B Vitamins Vitamin A Vitamin D Vitamin E

14. MINERALS Iodine Phosphorus Zinc Selenium Calcium Iron

15. CARBOHYDRATE AND DIETARY FIBER Egg contain only traces of carbohydrate and no dietary fiber

16. A large egg contains 77 Calories with 5 grams Fat 6 grams Protein

17. CHOLESTEROL Essential to the structure and function of all cells in the body Maintain flexibility and permeability

18. Gross Composition of the Egg % Water Protein Fat Ash Whole Egg 74 13 11 1 White 88 11 Yolk 48 17 13 1 Component % Shell 9 Yolk 29 Albumen 62 Fat/complete yolk 33 Protein/complete yolk 15.7 Yolk solids 51 Albumen protein 10.5 Albumen solids 11.8

19. Major Nutrients in 1 Egg (60g) Nutrient % Recommended Daily Allowance (RDA) Protein (g) 6.7 12 Energy (kcal) 78 11 Energy ( kjoules ) 324 11 Fat 6 n/a Polyunsaturated Fatty Acids (g) 1.17 12 Mono-Unsaturated Fatty Acids 2.46 20 Saturated Fat 2 n/a

20. Lysozyme Is used as an antibacterial in cheese and production Ovotransferrin This is the second major protein in egg white. It is an iron-binding protein consisting of 686 amino acids. 

21. NUTRITIVE VALUE OF EGG Egg is indeed one of nature‘s complete food. It contains high quality protein with all the essential amino acids, all of the vitamins except vitamin C, and many minerals. Egg contains high quality or complete protein with essential amino acids. Source of Energy – large supplies 75 calories Vitamins – Vitamin A, Vitamin B – Complex, Vitamin E Minerals – Phosphorous, Zinc, Folate – important for the prevention of birth defects and heart disease for the elderly. Omega 3 polyunsaturated fatty acids Lutein – reduces cataracts

22. Chalazae Egg Yolk Shell Membranes Air Cell Eggshell Albumen

23. Shell- has a thin outermost coating called the bloom or cuticle that helps keep out bacteria and dust. The color of the shell has no relation to quality. Shell color is determined by the breed of hen.

24. Inner and Outer Membranes -These two transparent protein membranes provide efficient defense against bacterial invasion. They can be found in between the shell and the egg white. They’re made a party of keratin, a protein that’s also in human hair.

25. Air Cell The air cell usually rests between the outer and inner membranes at the egg’s larger end, and it accounts for the crater you often see at the end of a hard-cooked egg. The air cell grows larger as an egg ages. An air space forms when the contents of the egg cool and contract after the egg is laid.

26. Albumen The egg white is known as the albumen, which comes from albus, the Latin word for “white.” Four alternating layers of thick and thin albumen contain approximately 40 different proteins, the main components of the egg white in addition to water.

27. Chalazae The two ropes of chalazae hold the yolk firmly in the middle of the egg, there is more thick white than thin white.

28. Yolk The yolk contains less water and more protein than the white, some fat, and most of the vitamins and minerals of the egg. All fats and cholesterol are found in the yolk. The yolk has a 30% composition of the whole egg.

29. Benefits of Egg Weigh management Build Muscle Strength and helps prevent muscle loss.

30. 3. Egg yolks are great source of choline. - Fetal brain development - Helps brain performance in adults.

31. 4. Eye Health Lutein and zeaxanthin are two anti oxidants found in egg yolks that helps avoid macular degeneration.
