Abstract

Most research on the formation of advanced glycation end-products (AGEs) and N-nitrosamines (NAs) in meat products has focused on high-temperature processing. The effects of low-temperature processing on AGEs and NAs formation have rarely been studied. This study investigated the effects of salt addition (0 %, 2 %, and 4 %) and lean-to-fat ratio (10:0, 8:2, and 6:4) on the formation of AGEs and NAs in Salami. We found that the salt in Salami would inhibit CEL formation. And the Lean pork Salami showed the highest N^ε-carboxyethyllysine (CEL) and lowest N^ε-carboxymethyllysine (CML) contents. For NAs content, it was lowest in Salami with 40 % fat. Principal component analysis and correlation analysis revealed significant correlations between CEL and N-nitrosodiphenylamine (NDPhA) formation in Salami. Additionally, the production of CML was correlated with the extent of fat oxidation, while CEL formation was more strongly associated with protein-related reactions. Furthermore, NAs formation correlated with protein content and protein oxidation.

不同配方和不同发酵阶段腊肠中晚期糖基化终产物和n -亚硝胺的形成

大多数关于肉制品中晚期糖基化终产物（AGEs）和n -亚硝胺（NAs）形成的研究都集中在高温加工上。低温处理对AGEs和NAs形成的影响很少被研究。本研究考察了盐添加量（0 %，2 %和4 %）和瘦脂比（10:0,8:2和6:4）对Salami中AGEs和NAs形成的影响。我们发现Salami中的盐会抑制CEL的形成。瘦肉腊肠中n -羧乙基赖氨酸（CEL）含量最高，n -羧甲基赖氨酸（CML）含量最低。脂肪含量为40% %的腊肠中NAs含量最低。主成分分析和相关分析表明，CEL与Salami中n -亚硝基二苯胺（NDPhA）的形成呈显著相关。此外，CML的产生与脂肪氧化的程度相关，而CEL的形成与蛋白质相关的反应更密切相关。此外，NAs的形成与蛋白质含量和蛋白质氧化有关。
