This study investigated the effects of different cooking methods on non-volatile flavor (free amino acids, 5'-nucleotides, and organic acids, etc.) of meat. The volatile flavor characteristics were also analyzed by electric nose and gas chromatography-ion migration spectrometry (GC-IMS). The results indicated that the content of flavor substances in meat varied significantly. The electronic tongue results indicated that the richness and umami aftertaste of roasting were significantly greater. The content of sweet free amino acids, 5'-nucleotides, and organic acids was also higher in roasting group. Electronic nose principal component analysis can distinguish meat cooked (the first two components accounted for 98.50% and 0.97%, respectively). A total of 36 volatile flavor compounds were identified among different groups, including 16 aldehydes, 7 olefine aldehydes, 6 alcohols, 4 ketones, and 3 furans. In general, roasting was recommended and gave more flavor substances in meat.

A convenient method is proposed using a heat-treatable volatile template to prepare hierarchical porous biochar (HPB). Litsea cubeba leaves and ZIF-8 served as carbon source and volatile hard template, respectively. The good compatibility between ZIF-8 and biomass facilitated their uniform dispersion, and the thermal decomposition of ZIF-8 created abundant pores in the HPB.

Fermentation is crucial for inducing desirable flavor and aroma profiles in cocoa products. This research focused on identifying microbial strains isolated from spontaneous cocoa fermentation in Hainan through 16S and Internal Transcribed Spacer (ITS) sequencing. Pectinase activity was screened, and metabolic dynamics of sugars and organic acids were analyzed using high-performance liquid chromatography.

This study aimed to employ a multi-omics method to identify key compounds contributing to the sensory flavour of mutton and to investigate the internal correlation between volatile metabolites and lipids in Cashmere goats and Tan sheep. The results demonstrate that the electronic nose can effectively and quickly distinguish goats and sheep meat. A total of 18 volatile metabolites and 314 lipids were identified as significant contributors to the flavour difference between goats and sheep meat, as determined by HS-SPME-GC-MS and lipidomic respectively.

The volatile profile of bee pollen samples from Central and Eastern Europe was investigated by headspace solid phase microextraction (HS-SPME) combined with gas chromatography-mass spectrometry-olfactometry (GC-MS-O). Sampling conditions were optimized for the extraction of volatiles. Pollen odorants were extracted with six different fiber coatings, five various extraction times, three diverse extraction temperatures and three differing desorption times.

However, the muscle of farmed exhibits a strong off-flavor, resulting in poor flavor quality. To enhance the flavor quality of the meat, this study examined the volatile compounds in muscle by establishing identification methods for these volatile odor compounds and comparing the differences between the two aquaculture modes.
