Egg production in Korea was 393 thousand M/T in 1990. More than 10 thousand M/T egg was imported and the amount imported has increased every year. Despite consumption tendency of increasing processed food, creation of additional demand is not likely because domestic egg consumption mainly depends upon table eggs. Processed eggs for marketing in Korea could be classified into two kinds. One is primary processed eggs including liquid eggs and egg powders. The other is secondary processed eggs which are further processed such as egg flake and egg curd. In addition to the above egg products, specific nutrient fortified eggs are produced through the modified feed formula and breeding techniques. The technologies developed so far including Korean patents are introduced. Convenient foods using egg and nutrient controlled eggs will be popular in the near future. For example, low cholesterol egg and polyunsaturated fatty acid fortified egg will be produced to meet the consumer demand. However, facing problems such as introducing egg quality grading systems and extending the short shelf-life of washed eggs should be solved as well.

Selenium(Se) is an essential trace element in the human body. Main function of this element is a catalytic part of antioxidant enzymes that protect cells against the attacks of free radicals that are produced during normal metabolism of the body. Se is also essential for normal function of the immune system and thyroid gland. It also appears to be a key nutrient in counteracting the development of virulence and inhibiting HIV(human immunodeficiency virus) progression to AIDS. It is also required for sperm motility and reduces the depression. Therefore, it is very meaningful that livestock producers generate Se-fortified animal products, such as Se-egg, Se-milk, Se-pork, Se-chicken and Se-beef from the point of producers as well as human heath. However, regulation on Se usage and Se-fortified food/feed is far from being clear in Korea even though Se should be carefully monitored because of its toxicity. Thus, one has to be aware of Se properties when designing Se-fortified animal products.
