Content of selected nonprotein components in poultry bone residue

The content of selected water soluble vitamins, minerals, and cholesterol in two types of poultry bone residue was evaluated. Bone residue from skinless input materials contained slightly, although significantly, more calcium, phosphorus, and potassium than the bone residue from skin containing input materials. The former residue also contained slightly more niacin than did the latter, but the content of this and the other water soluble vitamins that were analyzed was low. The lipid material in both products contained more cholesterol than many other edible animal fats.
