摘要: Multiomics and flavoromics were used to evaluate the effects of Sacha inchi oil (SIO) levels (0, 0.5, and 1 %) in hen feed on the sensory properties, volatile flavor, fatty acid composition, and flavor precursors in the resulting egg yolks. The addition of 0.5 % SIO improved consumer preference without causing off-flavors in the eggs. Thirty-eight volatile compounds were identified, of which thirty-five were significantly more abundant (P < 0.05) in the 0.5 % and 1 % SIO groups than in the control group. SIO additions enriched the egg ω-3 polyunsaturated fatty acid (PUFA) content and achieved the ideal healthy ratio of ω-6/ω-3. Lipidomics combined with partial least-squares regression model analysis suggested that oxidative degradation of the fatty acids aided the variations in the aroma characteristic between the 0.5 % SIO and control groups. Our results established that SIO additions effectively increased the ω-3 PUFA content in yolks and improved acceptability.
