Abstract

This study examined the effects of electrical stimulation on dry-cured tenderloin at different processing stages (0, 4, and 11 days), with a primary focus on lipid oxidation and the composition of volatile compounds. The study's results revealed that electrical stimulation enhanced lipase activity and accelerated lipid oxidation. Compared to the control group, the electrically stimulated samples exhibited higher total amino acid and fatty acid contents. Furthermore, the electrically stimulated group demonstrated superior taste (as assessed by an electronic tongue) and aroma profiles (as assessed by an electronic nose). Among the 49 compounds identified by GC-MS, the electrically stimulated dry-cured tenderloin displayed a greater diversity of volatile compounds. Notably, certain compounds, including ethyl lactate, ethyl myristate, 2,3-octanedione, and cyclohexanone, were exclusively detected in the electrically stimulated samples. These findings offer novel insights into the interplay between lipid oxidation and flavor development during meat processing via electrical stimulation.

期刊介绍： Food Chemistry: X, one of three Open Access companion journals to Food Chemistry, follows the same aims, scope, and peer-review process. It focuses on papers advancing food and biochemistry or analytical methods, prioritizing research novelty. Manuscript evaluation considers novelty, scientific rigor, field advancement, and reader interest. Excluded are studies on food molecular sciences or disease cure/prevention. Topics include food component chemistry, bioactives, processing effects, additives, contaminants, and analytical methods. The journal welcome Analytical Papers addressing food microbiology, sensory aspects, and more, emphasizing new methods with robust validation and applicability to diverse foods or regions.
