Abstract

Today, food enrichment is one of the most widely used methods in benefiting the food processing industry. The effects of four different dietary groups [basic diet (I), basic diet+flaxseed oil (II), basic diet+non-absorbable fiber+flaxseed oil (III)& basic diet+non-absorbable fiber+Fish oil (IV)] were studied on the development of Eggs with high content of long-chain Omega-3 fatty acids &vitamin D3. To achieve this goal, the Egg yolk oil was extracted by the cold extraction method and analyzed by Gas chromatography. A total of 24 fatty acid compounds were identified in Egg yolk oil, which ~4852% of contained monounsaturated fatty acids (mainly oleic acid). The diet modifications significantly (p<0. 05) increased the total content of Egg yolk Omega-3 fatty acids, and the highest value was observed in the diet (III) (84. 2% increase compared to the control). The highest elevations were observed in ALA (3. 49%), DPA (0. 24%), and DHA (1. 21%) fatty acids. Also, the ratio of ω,-6/ω,-3 fatty acids was ~18. 36% in the control group (I), while in the diets II, III, and IV, the ratios decreased to ~3. 79 (~80%), ~3. 16 (~83%), and ~6. 09 (~67%), respectively. Overall, the results indicated that diet (III) & (IV) were the most effective to increase the content of Omega-3 fatty acids and Vit-D3 in Egg yolk, respectively.
