How meat quality and sensory perception is influenced by feeding poultry plant extracts

Abstract

Copyright © World's Poultry Science Association 2015. The aim of this review is to discuss aspects of poultry meat quality which are influenced by supplementing the bird's diets with plant extracts. Nutritional approaches are often more effective than direct addition of the additive to meat since the compound is preferably deposited where it is most needed. Physical qualities of broiler meat, including pH and colour, is of major importance, since broiler chicken meat is nowadays usually consumed as cut up pieces or processed products. Sensory and proximate meat quality should be taken into consideration because this allows manufacturers to identify, understand and respond to consumer preferences more effectively. Lipids including cholesterol are an important component of meat and contribute to several desirable sensory characteristics of meat and meat products. Amongst meat products, poultry meat is considered to be more prone to the development of oxidative rancidity compared to red meat. This is explained by the higher content of phospholipids in poultry meat. The available literature is limited regarding changes in meat quality due to the effect of medicinal plants, especially in poultry, however this review will summarise the results of the investigations that have been published to date.
