Effect of garlic (Allium sativum) and onion (Allium cepa L.) extract chitosan nanoparticles on antioxidant enzymes activities and relative weight of visceral organs of rainbow rooster chicken

Poultry meat is susceptible to oxidation but increased antioxidant enzyme increases its availability in muscle during processing and storage. In livestock, synthetic antioxidant has some side effects; plant polyphenols can enhance the level of antioxidant enzymes but they are in-active in the gut of chicken and therefore, nanotechnology can be of importance in augmenting the stability of polyphenols. In the study,...
