Summary: Olives are an essential ingredient in Turkish food culture, and Turkey is one of the top producers of olives and olive oils in the world. This study found that traditional olive cultivars in Turkey are rich in health-promoting chemicals. There is significant variability among different cultivars, and metabolic fingerprinting approaches can be used to differentiate them.

Summary: Brettanomyces bruxellensis is the most commonly reported spoilage yeast in aged wines due to phenolic off-flavors. A study on 64 B. bruxellensis strains isolated from Catalonian aging wines revealed high intraspecific diversity and varying levels of tolerance to sulfur dioxide. The strains were also capable of producing volatile phenols even as they lost culturability over time.

Summary: The aim of this study was to investigate the changes in volatile organic compounds (VOCs) in 'Golden Delicious' apples caused by mechanical damage. Direct extraction and CAR/PDMS fiber were proposed as the best methods for identifying VOCs associated with mechanical damage. The study found that the mechanical damage resulted in changes in ester compounds in the apples.

Summary: In this study, volatile compounds in the pulp and skin of five table grape cultivars with different aroma types were qualitatively analyzed. The analysis identified 215 aroma compounds, including esters, terpenes, and alcohols. The transcriptomic analysis and terpene profiling data revealed several candidate genes and transcription factors involved in aroma biosynthetic regulation. The results provide new insights into the regulation of different aromas in grapes.

Summary: The study found that germinated brown rice (GBR) from Japonica rice cultivars contained higher levels of health-promoting compounds compared to Indica rice cultivars. No clear differences in volatile profiles were observed between the subspecies, but all volatile organic compounds exhibited significant reductions after germination, suggesting that Japonica cultivars might be preferred for health-conscious consumers seeking GBR products.

Summary: This investigation examined the relationship between different dry fermentation processes of coffee (aerobic, anaerobic, and CO2 modified atmosphere) and fermentation times, in relation to pH, acidity, and seven volatile marker compounds. The results showed that fermentation time had a significant effect on pH and acidity. The presence of acetic acid was positively correlated with fermentation time, while other compounds showed negative correlation. The different fermentation treatments had varying affinities with the volatile marker compounds analyzed.

Summary: The study analyzed volatile organic compounds (VOCs) from two commercially relevant Chinese truffle species and found diverse aroma characteristics influenced by genetic factors, soil, and microclimatic conditions. The dynamic pattern in the biosynthesis of VOCs suggests a complex interplay of factors affecting the aroma profiles of truffles.

Summary: In this study, the production of volatile organic compounds (VOCs) and their effect on growth were investigated by cultivating bacterial mixture (Rhizobium and Agrobacterium) and axenic Chlorella individually, in a mixed form, and through headspace connections. The results showed significant differences in VOCs produced by axenic Chlorella and Chlorella co-cultured with bacteria. The growth of co-cultured Chlorella was greatly enhanced, indicating the essential role of VOCs in growth and communication.

Summary: Headspace solid-phase microextraction coupled with gas chromatography-mass spectrometry (HSSPME-GC-MS) was used to analyze volatile compounds in minced pork meat during storage, with the origin of aromatic hydrocarbons in pork being verified by a migration test. Principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA) were utilized to characterize the profile of volatile compounds and identify potential volatile markers associated with pork spoilage. Three compounds were identified as additional indicators for quality control of pork based on their importance in discrimination of pork with different storage times.

Summary: Volatile aroma compounds in grapes and hops can exist as free volatiles or bound glycosides. These glycosides are transferred to fermented beverages during production, potentially releasing volatile compounds when hydrolyzed for consumer perception. The focus is on the presence of glycosides in raw materials, the impact of winemaking and brewing on glycoside levels, and current methods for analyzing glycosidically linked aroma compounds.

Summary: The isomeric nature of monoterpenyl glycosides makes it difficult to identify intact glycosides, posing a challenge in studying wine fermentation and storage. This study identified linalool, nerol, and geraniol monoterpenyl glycosides in Riesling grapes and monitored their changes during alcoholic fermentations across two years. Glycoside hydrolysis during fermentation could be related to relative concentrations of the corresponding free aglycones.

Summary: In this study, equilibrium distributions of hydrophobic solutes in closed systems containing vapor and aqueous solution were determined using HS-SPME. The presence of short-chain phospholipids influenced the partition coefficients and solubility values for the solutes, indicating different distribution patterns at various temperatures. The study also evaluated the partitioning of solutes between vapor phase, aqueous dissolution, and micelles, along with the effect of surfactant concentrations on partition coefficients and critical micelle concentrations.

Summary: This study found that volatile compounds from bird feathers can encode information about the MHC genes and play a role in mate choice. Individual MHC diversity, related to sex and breeding status, is reflected in feather chemicals, and similarity in MHC genotype is correlated with similarity in chemical profiles within female-female and male-female dyads.

Summary: The grapevine is an economically important plant, but the diversity of cultivated grapevines and genetic diversity of wild germplasm have declined significantly due to the focus on a few major cultivars in the global wine industry. Therefore, it is crucial to conserve grape germplasm resources through in situ and Ex situ methods.
