Abstract
The relationship between cooking oil fumes (COFs) control and meat flavor retention remains inadequately elucidated. In this study, an intelligent stir-frying system was employed to systematically investigate the effects of various fume-exhaust configurations on the flavor profile of pork belly and concomitant emissions of COFs. In the closed-exhaust group (CC), a total of 39 volatile compounds were identified, among which 3-methylbutanal, 2-methylbutanal, hexanal, and 2,5-dimethylpyrazine were identified as the key aroma-active components. Meanwhile, the CC group exhibited the most pronounced umami and saltiness characteristics. Nevertheless, the total airborne concentration of aldehydes and ketones in the CC group reached 4868.89 μg/m3, approximately 6.5 times that recorded in the open-exhaust group (OO). Network analysis revealed that fume-derived aldehydes and ketones exhibited both synergistic and competitive interactions with meat-derived volatile flavor compounds. Collectively, these findings provide a basis for achieving an optimal balance between flavor enhancement and effective COFs mitigation.
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.
