Amino Acids Profile of the Indonesian Endogenous Meats Antioxidant Peptides

Abstract

This study conducted to characterization amino acids of the antioxidant bioactive peptides from Indonesian endogenous meats among them "ongole cross breed" beef, "Kacang" goat meat, "Mojosari" duck meat and native chicken meat. The research was conducted in the Lamongan district of East Java. The method was laboratory exploration. The variables observed included antioxidant activity, crude protein and amino acids profile with LC-MS/MS. The results of studies appears there are variation in antioxidant activity of various endogenous meats in Indonesia. The highest crude protein was obtained native chicken meat 23.88 ±0.65%. Futhermore the highest antioxidant activity was obtained "Kacang" goat meat 12.085±0.22 %. The amino acids profile also exhibit diversity with each other. Amino acids obtained are distributed evenly to the types of essential and non essential amino acids. Ongole cross breed beef content a better amino acids profile than others. The beef appears to have higher contents of leucine, lysine and arginine of essential category.
