- Analysis of Water in the Chicken Eggshell Using the 1H Magic Angle Spinning Nuclear Magnetic Resonance Spectroscopy L Szeleszczuk DM Pisklak I Wawer Agrociencias pre disinfectant chilling tank Broiler carcasses Salmonella Enteritidis The water content of the chicken eggshell has a major influence on gas (CO 2 and O 2 ) permeability. Inappropriate water loss during the incubation period increases embryo mortality and decreases chick quality. So far only the procedures that enable to determine the total water content in the eggshell have been described and developed. Our analysis of the 1 H MAS NMR spectra of the chicken eggshell samples revealed three signals, differing significantly in the chemical shift and relaxation times (T1) parameters. In this work we have assigned those signals and described the changes in their intensities that occur during the incubation period. Using 1 H MAS NMR it is possible to distinguish two types of water reservoirs in the chicken eggshell. This approach can be used for more detailed analysis of the water content in the eggshells. 2016 artículo científico 1516-635X https://www.redalyc.org/articulo.oa?id=179749533003 en http://www.redalyc.org/revista.oa?id=1797 Revista Brasileira de Ciência Avícola application/pdf Fundação APINCO de Ciência e Tecnologia Avícolas Revista Brasileira de Ciência Avícola (Brasil) Num.2 Vol.18
