Consumer Perceptions of Eating Quality and Shelf-Life of Commercial Broilers

By day 3 of refrigerated storage, the level of oxidation in breast fillets form commercial and organic broilers was similar but free-range fillets exhibited signs of spoilage earlier than commercial fillets, according to a summary from Leopold Center for Sustainable Agriculture. Consumers found no differences in eating quality although trained panellists did.

Background and Methodology

This study compared eating quality and shelf-life of meat from organic free-range broilers to meat from commercially raised broilers. The commercial birds were 42 days of age before slaughter and the organic free-range birds were 10 weeks of age prior to slaughter. A total of 200 broiler breast fillets in two trials were obtained from a commercial processor and an organic free-range processor. The breast fillets arrived at the Texas Tech University Meat Laboratory within 24 hours of slaughter.


Free-range chicken breasts were significantly larger than commercial chicken breasts. Breast fillets from the free-range birds had higher pH values and were darker than meat from the commercially raised birds.

The oxidation (TBARS) levels on day 0 (24 hours post-slaughter) were significantly higher for the commercially raised broiler breast fillets but by day 3 of refrigerated storage, the level of oxidation was similar. Free-range fillets had significantly higher APC and coliform counts and exhibited signs of spoilage earlier than commercial fillets. Consumers evaluated breast fillets, using a ranking test and analysed using Kruskal-Wallis.

Consumers found no difference in fillet juiciness. tenderness or flavour. Trained panellists evaluated drums finding no difference in tenderness or flavour but determined that meat from free-range birds was juicier and had stronger attachment to the bone.
