Chondroitin sulphate distribution in broiler chicken carcasses

Abstract

1. The content of chondroitin sulphate (CS), known as a nutraceutical, was estimated in broiler chicken carcasses by analysing sulphated glycosaminoglycan uronic acid in posterior sternum (keel) cartilage and bones from 4 parts (wing, leg, front and hind) of carcasses.

2. The results of the present study suggested that approximately 0.63 g CS uronic acid (or 1.9 g as CS) can be extracted from a 1.66 kg whole broiler chicken carcass. The amount of extractable CS from keel cartilage, which has been reported as a valuable source of CS in broiler chicken carcasses, was surprisingly low (<10% of total CS).
