Abstract: Nutritional components of the whole viscera from Pteria penguin were analyzed and evaluated. General nutrients, amino acid compositions, fatty acid compositions and mineral contents were investigated. The results showed that the crude protein level in dry basis is 81.1% and the total content of the amino acids from protein is 13.0%. All kinds of essential amino acids are found in Pteria penguin. The first restricted amino acid is valine and the score of amino acid is 85.3. In addition, it is very rich in tasty amino acids such as glutamic acid, aspartic acid and lysine. The content of taurine is 722 mg/100 g, which accounts for 47.2% of the total free amino acids. The crude fat level is low and mostly made up of polyunsaturated fatty acids, in which, the contents of EPA and DHA are 12.61% and 30.28%, respectively. Mineral contents are high, especially Zn (435 mg/kg) and Se (0.68 mg/kg). All results suggested that Pteria penguin is a kind of high-quality seafood with particular flavors and high nutritional values.
