Mechanically separated seal meat (MSSM) and seal protein hydrolyzate (SPH) had minimal impact on N-nitrosamine formation in chicken salami. Cooking methods also showed little effect on these potentially harmful compounds.
Area of Science:
- Food Science
- Food Chemistry
- Toxicology
Background:
- N-nitrosamines are a group of potentially carcinogenic compounds.
- Understanding factors influencing N-nitrosamine formation in processed meats is crucial for food safety.
Purpose of the Study:
- To investigate the effect of mechanically separated seal meat (MSSM) and seal protein hydrolyzate (SPH) on N-nitrosamine formation in chicken salami.
- To assess the impact of different cooking methods on N-nitrosamine levels.
Main Methods:
- Chicken salami was prepared with varying levels of MSSM (10%, 20%) and SPH (1%, 2%).
- Samples were subjected to smoking, boiling, microwaving, and frying.
- N-nitrosamine content, including N-nitrosodimethylamine (NDMA), was analyzed using chromatographic techniques.
Main Results:
- Inclusion of MSSM or SPH resulted in only minor increases in NDMA levels compared to the control.
- Smoking had an insignificant effect on NDMA content.
- Cooking methods, including frying, showed limited impact on overall N-nitrosamine levels, with fried products containing up to 0.79 μg/kg NDMA.
Conclusions:
- MSSM and SPH do not significantly increase N-nitrosamine formation in chicken salami.
- Processing and cooking methods investigated had a limited effect on the levels of these compounds in the final product.

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...
