Abstract
Traditional meat products are highly valued all over the world and their attractiveness depends on socio-economical, ethical and religious factors as well as on their organoleptic properties that confer unique textural, gustatory, and olfactory characteristics. Taste compounds are closely related to protein degradation processes as hydrophilic metabolites such as amino acids, peptides and nucleotides are main contributors to final taste in traditional meat products. In this review, the generation of main compounds related to taste in traditional meat products are described, specially umami and koku peptides generated from the protein fraction during the traditional processing of these products. The use of certain peptides to enhance product taste and benefit human health is also highlighted.
期刊介绍:
The aim of Meat Science is to serve as a suitable platform for the dissemination of interdisciplinary and international knowledge on all factors influencing the properties of meat. While the journal primarily focuses on the flesh of mammals, contributions related to poultry will be considered if they enhance the overall understanding of the relationship between muscle nature and meat quality post mortem. Additionally, papers on large birds (e.g., emus, ostriches) as well as wild-captured mammals and crocodiles will be welcomed.
