Enriching Egg Yolk with Carotenoids and Phenols

Dried tomato peel (DTP) was tested in vivo (n=10) in 42 week-old laying hens at rates of 0, 40, 70, 100 and 130g/kg DM feed. Laying hens were fed in group 120 g DM/day/animal for 26 days. After 21 days, feed intake was not affected after DTP incorporation (97% of the offered feed in the five groups). Laying rate was not significantly different after DTP incorporation at 4 and 10% from the control group. Egg yolk resulting from DTP-enriched diets, contained lower amounts of cholesterol (14 to 17mg/g) and triglyceride (188mg/g) compared to the control group (22 and 241 mg/g, respectively) (P<0.0001). After DTP-enriched diets, content in total phenol was 2.0 to 3.6-fold higher, β-carotene 1.7 to 2.7-fold higher, and lycopene increased between 26.5 and 42.8μg/g compared to the control (P<0.0001). The optimal incorporation rate was 7% DTP.
