Description
Technical Field
The utility model belongs to the technical field of food safety, and relates to a device for eliminating nitrogen nitrosamine in grilled fish fillets.
Background
Nitrosamines are strong carcinogens and are among the most important chemical carcinogens. Dimethyl nitrosamine was found to cause cirrhosis of the human liver in 1954, and it was shown to cause carcinogenesis in rats in 1956. Since then, the importance of various national researchers has led to the development of numerous studies on nitrosamines. The content of nitrosamine in food has been reported at home and abroad. Nitrite is a precursor of nitrosamine, and is widely existed in nature, so that nitrosamine substances are easily formed in the processing or self-degradation process of organisms, and the nitrosamine substances in food are frequently detected.
Because the aquatic products contain abundant proteins, fats and amino acids essential to human bodies, after the processing processes of pickling, baking, frying and the like, a certain amount of N-nitroso compounds are generated in the aquatic products. At present, China sets a limit standard for marine products. The national standard for food safety GB 2762-2017 has established a limit standard for NDMA: the content of aquatic animal and its product is not more than 4.0 μ g/kg. The production of N-nitrosamines in aquatic products is of great concern to consumers. How to reduce the content of N-nitrosamine becomes an important research direction for aquatic products. The commonly used method for reducing the content of N-nitrosamine is to add antioxidant, plant polyphenol, spice, etc., but these substances affect the color, smell and taste of aquatic products, so the method is not suitable for aquatic products.
