Worked Solution & Example Answer:5. (a) Name four nutrients found in eggs - Leaving Cert Home Economics - Question 5 - 2006
Step 1
Name four nutrients found in eggs.
Answer
The four key nutrients found in eggs are:
(i) H.B.V. protein: Eggs contain high biological value proteins such as ovalbumin, globulin, vitellin, livetin, and albumin.
(ii) Lipid / fat: Eggs provide essential fatty acids, contributing to energy and health.
(iii) Minerals: Eggs are rich in calcium, iron (found in yolk), phosphorus, and sulfur.
(iv) B group vitamins: The yolk contains Vitamin A and small amounts of Vitamins D and E.
Step 2
List two effects of heat on eggs.
Answer
The two effects of heat on eggs are:
(i) Protein coagulates: When heated, the proteins in eggs denature and coagulate, leading to a firm texture.
(ii) Salmonella destroyed: Heat effectively kills harmful bacteria like Salmonella, making eggs safe to consume. However, too much heat can make eggs tough and difficult to digest, as the egg white changes from transparent to opaque.
