Liu, Shixin published the artcileLipolytic degradation, water and flavor properties of low sodium dry cured beef, Synthetic Route of 123-29-5, the main research area is low sodium dry cured beef lipolytic degradation.

The high sodium diet is harmful to the human body. In this study, beef was cured with some salt substitutes, namely SS, 39.7% NaCl, 51.3% KCl, 7% L-lysine and 2% L-histidine, in order to reduce the Na content for the final products, and salt substitute effects the physicochem., lipolytic, and flavor characteristics of dry-cured beef by determining free fatty acids, lipase activity, volatile compounds, and water mobility. The results showed that the lipase activity and unsaturated fatty acids were significantly increased due to the present of L-lysine and L-histidine. In addition, the SS could also enhance the lipoxygenase activity and promoted the lipid oxidation and influenced volatile compounds The changes of T21 and T22 showed that the water mobility in SS was higher (P < .05) than in the control group. Moreover, the cadaverine, histamine, and tyramine were detected in 57-day dry-cured beef, being below their toxic limits. The present study demonstrated that salt substitute by L-lysine and L-histidine alter the water distribution and mobility, improved the amounts and types of volatile compounds, while had no influence in the quality of product. International Journal of Food Properties published new progress about Beef. 123-29-5 belongs to class esters-buliding-blocks, name is Ethyl nonanoate, and the molecular formula is C11H22O2, Synthetic Route of 123-29-5.

Van Holle, Ann published the artcileSingle Nucleotide Polymorphisms and Biochemical Markers As Complementary Tools To Characterize Hops (Humulus lupulus L.) in Brewing Practice, Application of Methyl decanoate, the main research area is SNP biomarker hop characterization brewing; Humulus lupulus L.; biochemical fingerprinting; genotyping; growth location; quality.

In brewing practice, the use of the appropriate hop variety is essential to produce consistent and high-quality beers. Yet, hop batches of the same variety cultivated in different geog. regions can display significant biochem. differences, resulting in specific taste- and aroma-related characteristics in beer. In this study, we illustrate the complementarity of genetic and biochem. fingerprinting methods to fully characterize hop batches. Using genotyping-by-sequencing (GBS), a set of 1 830 polymorphic single nucleotide polymorphism (SNP) markers generated 48 unique genetic fingerprints for a collection of 56 com. hop varieties. Three groups of varieties, consisting of somaclonal variants, could not be further differentiated using this set of markers. Biochem. marker information offered added value to characterize hop samples from a given variety grown at different geog. locations. We demonstrate the power of combining genetic and biochem. fingerprints for quality control of hop batches in the brewing industry.

Bourbon-Melo, Nuno published the artcileUse of Hanseniaspora guilliermondii and Hanseniaspora opuntiae to enhance the aromatic profile of beer in mixed-culture fermentation with Saccharomyces cerevisiae, Product Details of C10H20O2, the main research area is beer Hanseniaspora fermentation Saccharomyces; Beer; Bioflavor; Co-fermentation; Hanseniaspora guilliermondii; Hanseniaspora opuntiae; Non-saccharomyces; Sequential fermentation; Simultaneous fermentation.

Beer production is predominantly carried out by Saccharomyces species, such as S. cerevisiae and S. pastorianus. However, the introduction of non-Saccharomyces yeasts in the brewing process is now seen as a promising strategy to improve and differentiate the organoleptic profile of beer. In this study, 17 non-Saccharomyces strains of 12 distinct species were isolated and submitted to a preliminary sensory evaluation to determine their potential for beer bioflavouring. Hanseniaspora guilliermondii IST315 and H. opuntiae IST408 aroma profiles presented the highest acceptability and were described as having ‘fruity’ and ‘toffee’ notes, resp. Their presence in mixed-culture fermentations with S. cerevisiae US-05 did not influence attenuation and ethanol concentration of beer but had a significant impact in its volatile composition Notably, while both strains reduced the total amount of Et esters, H. guilliermondii IST315 greatly increased the concentration of acetate esters, especially when sequentially inoculated, leading to an 8.2-fold increase in phenylethyl acetate (‘rose’, ‘honey’ aroma) in the final beverage. These findings highlight the importance of non-Saccharomyces yeasts in shaping the aroma profile of beer and suggest a role for Hanseniaspora spp. in improving it.

Drosou, Fotini published the artcileStudy of the Fermentation Kinetics and Secondary Metabolites of Torulaspora delbrueckii Yeasts from Different Substrates, Application In Synthesis of 106-32-1, the main research area is Torulaspora Saccharomyces fermentation secondary metabolite brewing.

Due to global competition and consumer demand for innovative products, the brewing industry is exploiting research to create new beer products with complex aromatic profiles. Recently, interest has been focused on non-Saccharomyces yeast strains, employed in the wine sector. In this study, the capability of two Torulaspora delbrueckii strains (T.d. 291 and T.d. Prelude) on metabolizing the basic sugars of wort was investigated and compared with a S. cerevisiae strain (S.c. US-05). More specifically, the consumption of wort sugars (glucose, fructose, maltose, and their mixtures) and the production of ethanol and secondary metabolites were studied, at two fermentation temperatures (20°C and 13°C). From the results of the fermentation kinetics, it was concluded that both T. delbrueckii yeasts are able to metabolize all sugars, produce a satisfactory amount of ethanol and grow at either temperature, although with a faster rate at 20°C. The volatile compounds were significantly affected by the fermentation temperature and the sugar used. Both T. delbrueckii strains demonstrated potential for use in brewing.

Kincl, Tomas published the artcileHigh-gravity brewing without adjuncts – The effect on beer parameters, Synthetic Route of 106-32-1, the main research area is beer high gravity brewing acetate ester flavor.

High-gravity brewing (HGB) is a common practise in industrial breweries. The aim of this study was to examine the effect of HGB on anal. and quality parameters of all-malt beer. Parameters were evaluated in bottom-fermented (BF) beer and some data were compared with results from top-fermented (TF) beer. In both, BF and TF beer, two brews were produced where a higher original gravity (OG) beer was diluted to the level of a lower OG beer. Increased ester production was the principal reason for changes in the flavor profile. Especially higher levels of acetate esters (Et acetate, isoamyl acetate) affected beer aroma, creating fruity and solvent-like odors. Higher alc. and acetaldehyde contents were not affected by HGB. The use of HGB for BF beer did not affect important quality parameters such as thiobarbituric acid number (TBA) or foam stability. The content of beer ageing markers (carbonyl compounds) was also not affected by the use of the HGB technol. In sensorial evaluation, differences in flavors of BF HGB beer were evaluated in a triangle test. Beer without dilution was preferred by tasters, commenting on better harmony in bitterness and beer body.

Ramsey, Imogen published the artcileAssessing the sensory and physicochemical impact of reverse osmosis membrane technology to dealcoholize two different beer styles, Application In Synthesis of 110-42-9, the main research area is beer dealcoholization sensory physicochem impact reverse osmosis membrane technol; Dealcoholization; Non-alcoholic beer; Physicochemical; Reverse osmosis; Sensory.

A pilot scale dealcoholisation unit fitted with reverse osmosis (RO) membranes was used to directly compare two beer matrixes (stout, lager, ∼ 5% ABV) and their dealcoholized counterparts (∼0.5% ABV), for physicochem. properties (volatiles, pH, ABV, polyphenols, bitterness) and sensory profiles using a trained descriptive panel (n = 12). The efficiency and consistency of RO membranes were evaluated by replicate dealcoholisation trials (n = 3) for each beer. Statistical anal. revealed significant reductions (p < 0.05) in key volatile compounds with linear structures (Et octanoate, octan-1-ol) compared to those with increased levels of branching (3-methylbutyl acetate, 2-methylpropan-1-ol). Significant reductions (p < 0.0001) in fruity/estery, alc./solvent, malty, sweetness and body sensory attributes were also discovered. Finally, longer processing times for the stout across replicate trials suggested membrane clogging, while differences in volatile reduction suggested membrane fouling. This novel research proposes compound structure, rather than compound size, impacts RO membrane permeability and resulting sensory quality.

Perestrelo, Rosa published the artcileDifferentiation of fresh and processed fruit juices using volatile composition, Application of Methyl decanoate, the main research area is Vitis Fragaria fresh processed fruit juice volatile composition; GC-MS; HS-SPME; fresh juice; processed juice; volatile pattern.

In the current study, a comprehensive approach based on headspace solid-phase microextraction (HS-SPME), combined with gas chromatog.-quadrupole mass spectrometry (GC-qMS), was used to establish the volatile signature of fresh and processed fruit juices, obtained from the same batch of grapes, red fruits, orange, pear, and apple. This is a powerful tool for evaluating the impact of the production process on the volat. pattern of fruit juice. A total of 169 volatile organic compounds (VOCs) belonging to different chem. groups were identified. Esters, carbonyl compounds, terpenoids, and alcs. are the major chem. groups in the investigated fruit juices. However, their contribution to the total volatile profile varied. Special attention should be paid to processed fruit juices to avoid the possible deleterious effects associated with the formation of furanic compounds (e.g., heat treatment), since their furanic content was significantly higher in comparison to that of fresh fruit juices. The knowledge obtained in the current study will allow for the introduction of modifications to the process involved in processing juice, which will improve the organoleptic characteristics of processed juices, contributing to a better acceptance by consumers. Furthermore, more assays should be performed to assess the effect of harvests, geog., and agronomy on the volatile profile of juices.
