Abstract

In order to reduce the salt content of Xuanwei ham and prevent the fading of the ham section, 18 hind legs of local black pigs were selected. The groups were cured with 6 % salt, 6 % compound curing agent I, and 6 % compound curing agent II, respectively. The differences in small molecule metabolites and microbial communities in Xuanwei ham among the groups were analyzed. The results showed that the compound curing agents promoted the release of many small molecule metabolites. The use of sugar led to the down-regulation of small molecule metabolites such as biogenic amines. Bacteria is the main cause of changes in small molecule metabolites of Xuanwei ham. Aspergillus potentially affect amino acid regulation, Yamadazyma and Debaryomyces promote lipid metabolism, and Staphylococcus promotes lipid oxidation and production of volatile compounds. These findings indicate that the compound curing agents affects small molecule metabolites and microbial communities in Xuamwei ham.

基于代谢组学和高通量测序的复合固化剂对宣威火腿小分子代谢物和微生物群落的内在影响分析

为降低宣威火腿的含盐量，防止火腿断面褪色，选用当地黑猪后腿18只。分别用6 %盐、6 %复合固化剂I和6 %复合固化剂II进行固化。分析各组宣威火腿小分子代谢物和微生物群落的差异。结果表明，复合固化剂促进了许多小分子代谢物的释放。糖的使用导致小分子代谢物如生物胺的下调。细菌是宣威火腿小分子代谢物变化的主要原因。曲霉可能影响氨基酸调节，山曲霉和Debaryomyces促进脂质代谢，葡萄球菌促进脂质氧化和挥发性化合物的产生。上述结果表明，复合固化剂对宣威火腿的小分子代谢产物和微生物群落有影响。

期刊介绍： The aim of Meat Science is to serve as a suitable platform for the dissemination of interdisciplinary and international knowledge on all factors influencing the properties of meat. While the journal primarily focuses on the flesh of mammals, contributions related to poultry will be considered if they enhance the overall understanding of the relationship between muscle nature and meat quality post mortem. Additionally, papers on large birds (e.g., emus, ostriches) as well as wild-captured mammals and crocodiles will be welcomed.
