These values were higher than those obtained by Li, Shao, Zhu, Zhou, and Xu (2013), who detected about 50e70% of the nitrite added to dry-cured sausages. Fernandez-Lopez, Sendra, Sayas-Barbera, Navarro, and Perez-Alvarez (2008) and Carballo and Andrade (2013) also reported lower detection values in Spanish dry-fermented sausages.
