Simon Amoikon, Tiemele Laurent published the artcileA study on the potential of yeasts isolated from palm wines to produce flavouring compounds, Application In Synthesis of 106-32-1, the main research area is Saccharomyces Debaryomyces palm wine synthetic flavouring agent.

Despite the increasing importance of palm wines as a key element in Ivorian socio-cultural practices, and the high involment of yeasts in the production of these beverages, no studies have been devoted to aroma production of yeasts and their potential uses in biotechnol. applications. In this work, aroma profiles of 20 non pathogenic yeast strains (11 from raffia and 9 from ron, representing 13 species) among the 21 yeasts isolated were established using HS-SPME-GC/MS anal. A total of 50 Volatile Organic Compounds (VOCs) produced by these yeasts were identified and grouped into five main families, namely higher alcs., aldehydes, ketones, organic acids and esters. Among these VOCs, esters were the most abundant (28 compounds). Some strains produced specific compounds of technol. interest which could be used for diverse applications, such as beverages, ice creams, baked goods and desserts and synthetic flavouring ingredient. Among them, Hanseniaspora jakobsenii CLIB 3083 produced the highest number of VOCs.

De Flaviis, Riccardo published the artcileVolatiles profile of ‘Blanche’ wheat craft beer as affected by wheat origin: A chemometric study, Computed Properties of 123-29-5, the main research area is volatile blanche wheat craft beer; Aroma profile; GC–MS; Landrace; Multivariate analysis; PLS-DA; SPME; Volatile organic compounds; Wheat craft beer.

The aroma of craft beers is recognized to affect their overall acceptability and drinkability. Raw materials can affect the volatile organic compounds (VOCs) of beers and their aroma. The VOCs profile of wheat craft beers produced with wheat (Triticum aestivum, L.) of different origin (variety and cultivation site) in increasing concentration was analyzed. PLS2 anal. evidenced that wheat concentration is the main factor affecting VOCs profile, while the effect of variety (Vittorio and Solina) and altitude of cultivation (70, 500 and 1,200 m a.s.l.) on VOCs variance was lower. PLS-DA permitted to differentiate beers obtained with the two varieties for their VOCs profile: 2-Ethylhexanol, a cultivar specific indicator, was found in beers made with Solina.

Ceccaroni, Dayana published the artcileSpecialty rice malt optimization and improvement of rice malt beer aspect and aroma, COA of Formula: C10H20O2, the main research area is Oryza specialty malt beer aroma.

Although brewing beer with cereals other than barley malt is an established trend, producing a tasty product in this manner represents an ongoing research challenge. Rice malt beer represents a gluten-free beverage for individuals with celiac disease. Previous research on rice malt beer has shown a notably flat sensory profile and a low pale color. The use of special rice malts could be a means of enhancing the flavor, taste, color and body of a rice malt beer. To the best of our knowledge, no research has been performed on the use of rice for the production of specialty malts. An exptl. study to obtain two different types of special rice malt, namely, caramelized and dark, was conducted. Quality attributes of the obtained malts were determined A top fermented beer from pale rice malt and special rice malts was produced and analyzed to evaluate the sensorial properties. The resulting beer displayed a malted profile and an amber color. The use of the special rice malts enhanced the flavor and the color, in addition to the stability and the nutritional value, of the beer, thanks to their high polyphenol content and their good antioxidant capacity.

Alves, Vera published the artcileBeer volatile fingerprinting at different brewing steps, HPLC of Formula: 106-32-1, the main research area is beer isoamyl acetate acetaldehyde fingerprinting; Beers; Brewing process; HS-SPME/GC–MS; VOMs; Volatile fingerprint.

Volatile fingerprints of a lager beer were carried out throughout five brewing steps to characterize the changes encompassing this process. Overall, 60 volatile organic metabolites (VOMs) were identified by headspace solid-phase microextraction followed by gas chromatog. mass spectrometry (HS-SPME/GC-MS). Specific profiles were observed at different brewing steps – aldehydes and furans dominate in wort, whereas the aliphatic esters and alcs. predominate in the following steps. Such variations can be assigned to specific VOMs, as 3-methylbutanal (wort), Et alc. and Et octanoate (fermentation, maturation and filtration), or Et alc. and isoamyl acetate (final product). These VOMs can influence the beer final flavor. Et alc. contributes to its strong and pungent smell and taste, while isoamyl acetate adds intense ‘fruity’ and ‘banana’ odours. These beer volatile fingerprints constitute a valuable tool to obtain insights on the impact of each brewing step on the final product, being also very useful for certification purposes.

Li, Shan published the artcileImpact of NSLAB on Kazakh cheese flavor, Category: esters-buliding-blocks, the main research area is Pediococcus Staphylococcus Lactobacillus Kazakh cheese flavor; Fermented dairy products; Flavor compounds; Flavor quality; Kazakh; Non-starter lactic acid bacteria; Ripening.

Xinjiang is a multiethnic region of China. Traditionally, most ethnic minorities are known to produce and consume cheese. Nomadic people have been reported to use lactic acid bacteria (LAB) for decades to produce fermented dairy products as part of a balanced diet. Non-starter LAB (NSLAB) contribute to different degrees of ripening, depending on the cheese variety. In the present study, we screened three types of NSLAB with good proteolysis and autolytic abilities from traditional Kazakh cheese: Pediococcus acidilactici R3-5, Staphylococcus epidermidis R4-2, and Lactobacillus rhamnosus R9-6. A control (no NSLAB) was also included, resulting in four distinct types of cheese samples. We used gas chromatog.-mass spectrometry and the electronic nose system to identify volatile compounds and analyze the effect of NSLAB on cheese flavor at the ripening stage. The physicochem. indicators changed significantly during the ripening of Kazakh cheese. Compared with the control, the protein content, free fatty acid content, pH, flavor compounds, and odor profiles of the test cheeses were significantly different. The major chem. differences among cheeses were the synthesis of some key volatile components (Et caprylate, Et caprate, myristyl carbonate, capric acid, caprylic acid, nonanal, and benzyl alc.). NSLAB can be used as an adjunct starter to make Kazakh cheese and the use of NSLAB affected the cheese flavor quality pos.

Fan, Xiaojing published the artcileCharacterizing the volatile compounds of different sorghum cultivars by both GC-MS and HS-GC-IMS, Computed Properties of 123-29-5, the main research area is sorghum volatile compound GC MS IMS; GC-IMS; GC-MS; Odor-active value; Sorghum; Volatile compound.

The current study applied both GC-MS and GC-IMS for characterizing volatile compounds of six Australian sorghum cultivars. For raw sorghum, the result of GC-MS showed that ester compounds were abundant in six raw samples. Among these esters, the content of hexadecanoic acid Et ester was highest in all of the raw samples. Compound 3-octanone only existed in Apollo, Bazley and Liberty, and 2-undecanone was found to be in MR43. Result of GC-IMS showed that signals of benzaldehyde, 2,3-butanedione were generally noted in six raw samples. In general, The Apollo and Buster had more volatile compounds, followed by Bazley and Liberty. In contrast, MR43 and G44 had least volatile compounds For cooked sorghums, more fatty aldehydes are formed compared to its corresponding raw sample, in which current data indicated that 40 volatile compounds were identified by GC-MS, and 11 of them were identified as the key aroma compounds More important, variation in the compounds of hexanal, heptanal, octanal, 2-heptenal, nonanal, trans- 2-octenal, benzeneaceldehyde, (E)-2-nonenal, 1-octen-3-ol, 1-pentanol, 2-methoxy-4-vinylphenol and 2-pentylfuran might be applied for explaining the aroma characteristics among six sorghum cultivars. Result of GC-IMS showed that 26 volatile compounds but not in results from GC-MS detection, indicating advantage of methodol. combination for a better understanding impact of cultivars and cooking on volatile characteristics of sorghums.
