Abstract :
yield of by-products from food processing which are suitable as livestock feed is determined by two main factors, the dietary habits of human beings and the production capacity of alternative feed resources. The second of these is often determined by the land area available for feed production. Korea is a small country with a high population density, and lacks natural feed resources. It is dietary habits therefore which mostly determine which by-products are available as livestock feed. The main food processing by-products available in Korea are brewersʹ grain and distillersʹ grain from the alcohol industry, condensed molasses fermentation soluble, fermented soybean paste residues from the making of sauces and seasonings, by-prducts from the manufacture of instant noodles, soybean curd residues, and ginseng meal from medicinal herbs. Jeju island in the south of Korea produces a relatively large amount of citrus, and generates considerable amounts of citrus pulp when these are processed into juice. Korea imports a large quantity of feed resources (15 million mt per year), mainly from USA and Southeast Asia. Utilization of indigenous by-products for livestock feed is urgently required, to rais the international competitveness of Koreaʹs livestock production. Unfortunately, most by-products are at present being discarded as wastes, which causes environmental pollution. Therefore, changes in goverment policy might be necessary to facilitate the utilization of by-products, while more research on their use is also needed.
