Hen eggs are considered the cheapest protein but a valuable protein source. The global per capita consumption is estimated at around 161 eggs, a high number that has been increasing over the years. However, not all people around the world consume this food. This is why some researchers evaluated spray-dried eggs as a micronutrient-rich nutritional supplement.
“Regular consumption of hen eggs can help to prevent deficiencies of essential nutrients, such as essential amino acids, vitamin A and E or trace elements zinc and selenium, for vulnerable populations.”
This study aimed to assess the nutritional value of spray-dried eggs, favored by their manufacturability, storability, and ease of addition to (complementary) foods.
The idea was to record and compare the nutrient profiles of commercially produced pasteurized whole eggs and their respective powder samples spray-dried at 160°C. This study demonstrated that spray-drying could mostly retain the high nutritional quality of pasteurized whole eggs without accumulating potentially harmful compounds.
Important nutrients that were not significantly affected by spray-drying include:
Also, the potential of eggs in helping to prevent malnutrition in vulnerable population groups is further enhanced by their possible use in:
Spray-dried, concentrated form, with easier storability, which both represent crucial factors for the application in low- and middle-income countries.
Highlights of the results:
A daily intake of spray-dried egg powder corresponding to one medium-sized egg meets dietary reference values for children, e.g., 100% for vitamin E, 24% for retinol, 61% for selenium, and 22% for zinc.
