Production method of special ingredient-containing column

摘要

The extracted fish oil obtained by extracting fish oil containing a large amount of DHA on the non-processed portion treated as waste in the processing of aquatic foods, the concentrated fish oil obtained by saponification, urea addition reaction and concentration treatment of this extracted fish oil, A method for producing DHA-containing lilies in which any one of powdered fish oil added with an emulsifier and an antioxidant is added to a poultry feed for egg laying and fed and raised so that DHA is contained in an amount of not less than 0.5 g per 100 g of egg yolk.;It is preferable to add 0.5-5.0 wt% of DHA-containing extracted fish oil (containing DHA 17-42%), 0.1-2.5 wt% of concentrated fish oil, and 0.5-2.5 wt% of powdered fish oil to the poultry feed for laying.;By obtaining the DHA-rich source of fish oil on an inexhaustible portion treated with waste (the head portion of the tuna, the eye tissue, the skin, the internal organs, the internal surface of the male fish and the squid), it is possible to supply the high-It also contributes to the prevention of pollution. By containing DHA content of 0.5 g or more per 100 g of egg yolk produced, it is possible to effectively produce a column containing a large amount of DHA.
