The Claim
Supplementation with natural pigments from paprika and marigold extracts is associated with delayed deterioration of internal egg quality parameters—specifically albumen weight, Haugh unit, and yolk percentage—during storage in Japanese quail eggs, suggesting a potential extension of shelf life.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Feeding quails natural plant pigments from paprika and marigolds might help keep their eggs fresher for longer by slowing down changes inside the egg as it's stored.
See the scientific wording
Natural pigments from paprika and marigold extracts are linked to maintenance of internal egg quality parameters during storage in Japanese quail eggs, with changes in albumen weight, Haugh unit, and yolk percentage occurring later in supplemented eggs, suggesting potential shelf-life benefits.
What the research says
1 studyThe study found that eggs from quails fed paprika and marigold stayed fresher longer, with key quality measures like egg white thickness and yolk size changing more slowly over time, which supports the idea that these natural pigments help preserve egg quality during storage.
