Description

DETAILED DESCRIPTION

Example 1: Preparation of the Egg White and Egg Yolk Mixture with a 50% Reduction in the Cholesterol Content with Respect to Natural Egg

[0019] To prepare the mixture of the present invention, firstly, the eggs were selected; a sample was taken to know their physico-chemical composition and determine the ratio of number of egg yolks:number of egg whites that the sample should have contained so that the mixture of the present invention had 50% less cholesterol content than normal eggs; the egg yolks and egg whites were mixed in a ratio of 8:92-20:80.

[0020] To prepare 200 kg of mixture, the eggs were taken to the egg breaker and separator machines, which enabled the egg yolks to be separated from the egg whites. Next, the egg yolks were mixed with the egg whites in a ratio of 16:84 and between 0.15 and 0.4% by weight of natural carrot and pumpkin extract was added.

[0021] Lastly, the mixture was homogenised in a homogenisation tank, and it subsequently was pasteurised at a temperature comprised between 60° C. and 65° C. for 4.5 to 6.5 minutes.

Example 2: Preparation of the Egg White and Egg Yolk Mixture with a 70% Reduction in the Cholesterol Content with Respect to Natural Egg

[0022] The mixture of the present invention was prepared in the same way as in the previous example, but the ratio of egg yolk:egg white was 10:90.

Example 3: Comparison of Nutrients and Cholesterol Content of the Mixture of the Present Invention, Natural Egg, Egg Product with Egg White Only and Egg Product with Egg Yolk Only

[0023] For the comparison between the nutrients and cholesterol content of the mixture of the present invention, obtained as indicated in example 2, with natural egg, egg yolk-based egg product and egg white-based egg product, a sample of each of the products was taken and each of the nutrients was measured (Protein—Kjeldahl Method, Moisture—Drying oven, Fat—Volumetric determination using a butyrometer, Ash—Muffle furnace, Carbohydrates—Fehling Reaction Test, Glucose—Chromatography, Calories—calorimeter, Cholesterol—Liebermann-Burchard Spectrophotometry). Table 1 shows the comparison of nutrients, Table 2 shows the comparison of vitamins and Table 3 shows the comparison of minerals.
