Promoting the consumption of fruits is a key objective of nutrition policy campaigns due to their associated health benefits. Raspberries are well appreciated for their remarkable flavor and nutritional value attributable to their antioxidant properties. Consequently, one of the objectives of present-day raspberry breeding programs is to improve the fruit′s sensory and nutritive characteristics. However, developing new genotypes with enhanced quality traits is a complex task due to the intricate impacts genetic and environmental factors have on these attributes, and the difficulty to phenotype them. We used a multi-platform metabolomic approach to compare flavor- and nutritional-related metabolite profiles of four raspberry cultivars (′Glen Ample′, ′Schönemann′, ′Tulameen′ and ′Veten′) grown in different European climates. Although the cultivars appear to be better adapted to high latitudes, for their content in soluble solids and acidity, multivariate statistical analyses allowed us to underscore important genotypic differences based on the profiles of important metabolites. ′Schönemann′ and ′Veten′ were characterized by high levels of anthocyanins and ellagitannins, resp., ′Tulameen′ by its acidity, and ′Glen Ample′ for its content of sucrose and β-ionone, two main flavor contributors. Our results confirmed the value of metabolomic-driven approaches, which may foster the development of cultivars with enhanced health properties and flavor.

Anaya, Juan Alberto published the artcileApplying rosemary extract and caffeic acid to modify the composition of Monastrell wines, Safety of Ethyl octanoate, the main research area is Monastrell wine polyphenol aromatic compound rosemary extract caffeic acid.

This work studies the effect of applying rosemary extract and caffeic acid on the polyphenolic and aromatic composition of Monastrell wines, as well as the influence of traditional winemaking or incorporating prefermentative maceration. For this purpose, three treatments were carried out in triplicate. In one of them, rosemary extract was applied on the clusters 10 days before harvest, caffeic acid was applied in the same way in another, and, finally, this acid was applied to grape before crushing. Each treatment was run by both traditional vinification and vinification with prefermentative maceration. After making wines, they were monitored for 12 mo after fermentation The application of rosemary extract, and that of caffeic acid but to a lesser extent, increased the color, the concentration of anthocyanins, and the percentage of polymerized anthocyanins, while prefermentation maceration gave rise to wines with a higher concentration of condensed tannins and polyphenols. Applying rosemary extract and caffeic acid in the vineyard also increased the concentration of esters and other compounds that favor wine aromatic quality, which was also enhanced by prefermentative maceration.

Budak, Nilguen H. published the artcileThe changes of physicochemical properties, antioxidants, organic, and key volatile compounds associated with the flavor of peach (Prunus cerasus L. Batsch) vinegar during the fermentation process, Synthetic Route of 140-11-4, the main research area is Prunus cerasus fermentation organic volatile compound antioxidant physicochem property; ORAC; geraniol; key aroma compounds; linalool; peach vinegar; peach wine; phenylacetic acid; ɣ-decalactone.

Peach is a delicious food preferred by consumers and widely used in the manufacture of peach juice, peach juice concentrate, peach jam, dried fruit, puree, etc. Alternatively, peach can be used in the production of vinegar. In this study, peach vinegar was produced as an alternative to other industrial products produced from peach. In this study, it was determined that the TPC content and ORAC value of peach vinegar were higher than those of peach juice and peach wine. In addition, the major contributor compounds to the aroma profiles of the samples were the γ-decalactone, linalool, and geraniol compounds for the peach juice; the ethanol, -decalactone, phenylacetic acid, acetic acid, 2-phenylethanol, Et decanoate, the linalool, and the decanoic-acid for the peach wine; and the -decalactone, phenylacetic acid, acetic-acid, phenethyl-acetate, and isovaleric acid for the peach vinegar. It is thought that the results of this study will pave the way for the widespread production of vinegar from peach, which has pos. effects on health, is rich in volatile aroma components, and has a high potential to be preferred. Furthermore, this study is the first detailed study so far on peach vinegar. Practical applications : In this study, it was aimed to produce vinegar as a new and alternative foodstuff product from peach fruit which was normally processed as fresh or/ dried fruit, fruit juice, puree, and canned fruit by the industry. An alternative idea was created for the use of peach fruit, which has a short shelf life. In the study, the antioxidant capacity, organic compounds, and volatile compounds associated with aroma profile of peach vinegar during the fermentation process were determined Moreover, the changes of these compounds were monitored during the fermentation process. The results of the study are a guide for the usability of peach fruit as a raw material in the production of peach vinegar, which has potentially pos. effects on health, is rich in volatile aroma components, and has a high potential to be preferred. Furthermore, this study is the first detailed study on peach vinegar.

Nine ciders obtained by cryo-extraction were analyzed for chem., olfactometric and sensory characteristics. Three types of ice apple juices and three autochthonous yeast strains were evaluated. The quant. volatile profile is mainly influenced by the apple juice. Regarding the olfactometric profiles of the ice ciders, 23 odorants not previously found in Spanish still ciders, and described as sweet, spicy, fruity and floral were observed Among these, it is worth mentioning 5 high-b.p. compounds found in an olfactometric zone where heavy, phenolic odours predominate in still ciders. The sensory descriptions obtained by Check-All-That-Apply classified the ice ciders mainly by their sweet taste and smoothness, these attributes being the most influential in the assessment of the overall quality of the ciders. The most highly valued ciders were described as the sweetest, most fruity ones, in agreement with their having the highest values for the ratio between total sugars and total acidity.

The aim of the present study was to perform simultaneous alc. and malolactic wine fermentations using free or immobilized kefir culture at a wide temperature range (5-45 °C). Repeated batch fermentations were carried out for a period up to 29 mo, suggesting a high operational stability of the systems, while malic acid conversion and ethanol productivity up to 70.9% and 36.9 g/(Ld) were noted. Volatile acidity was at levels typically found in wines (<1.0 g acetic acid/L) in most cases, although increased values were recorded in wines produced at 5 °C, but no vinegar taint was detected. Fusel alcs. were at levels usually found in wines, but were reduced at 5 °C. Application of PCA to minor volatiles showed that the fermentation temperature rather than the nature of kefir culture had a significant effect. Noticeably, all products were accepted by the panel during the preliminary sensory evaluation.

Li, Xiaonan published the artcileCloning and expression of Lactobacillus brevis β-glucosidase and its effect on the aroma of strawberry wine, SDS of cas: 123-29-5, the main research area is aroma cloning Lactobacillus brevis strawberry wine.

The aim of this study was to evaluate the effect of β-glucosidase (Lb0241) derived from Lactobacillus brevis on the aroma of strawberry wine. The recombinant Lb0241 was cloned and expressed in Escherichia coli BL21 (DE3). The effect of temperature, pH, and additives on the activity of Lb0241 and its substrate specificity and kinetic parameters were analyzed. Furthermore, the effects of Lb0241 on the aroma properties of strawberry wine were evaluated by SPME-GC-MS and sensory evaluation. Lb0241 showed remarkable specificity for β-glucoside and displayed the highest activity at pH 5.0 and 30°C, with a relative activity of 55% in 12% ethanol. Ni2+ and K+ could increase the activity of Lb0241, but Fe2+, urea, 2-hydroxy-1-ethanethiol, and sodium dodecyl sulfate showed the opposite effect. Lb0241 could increase the aroma-active volatiles of esters, terpenoids, and phenols, and decrease alcs. and volatile acids. Overall, Lb0241 showed promising prospects in terms of aroma release in strawberry wine. Practical applications : A notable part of non-volatile glycosidic precursors present in fruit wine constitutes a reserve of potential aroma-active mols. Thus, the hydrolysis of aromatic precursors could significantly enhance the aroma of fruit wine. Our results showed that the new β-glucosidase Lb0241, which was derived from Lactobacillus brevis T61, exhibited strong acid and ethanol resistance. Moreover, Lb0241 could effectively hydrolyze aromatic precursors and enhance the level of aroma compounds in strawberry wine. Therefore, Lb0241 has potential application prospects and economic value to improve the flavor of fruit wine.

Pham, Duc-Truc published the artcileInfluence of partial dealcoholization on the composition and sensory properties of Cabernet Sauvignon wines, Formula: C10H20O2, the main research area is Cabernet Sauvignon wine dealcoholization reverse osmosis evaporative perstraction; Alcohol sweetspot; Descriptive analysis; Evaporative perstraction; Reduced alcohol wine; Reverse osmosis.

Worldwide, winemakers are increasingly adopting alc. management strategies to counter the higher wine ethanol concentrations observed over the past ∼30 years. Wines with high ethanol levels exhibit increased ‘hotness’ on the palate, which is generally considered to neg. impact wine quality. This study investigated changes in the chem. and sensory profiles of five Cabernet Sauvignon wines following their partial dealcoholization by reverse osmosis-evaporative perstraction (RO-EP). Descriptive anal. (DA) of wine before and after RO-EP treatment indicated dealcoholization did not strongly affect wine aroma and flavor, consistent with the small changes observed in wine chem. composition However, significant differences in the perception of wine palate attributes were observed, with dealcoholized wines found to exhibit lower acidity, sweetness, bitterness, saltiness and/or body. Astringency was enhanced following partial dealcoholization of one wine, but diminished in another. Sensory trials were also undertaken to determine the optimal ethanol concentration of wines, or the ‘alc. sweetspot’. Two approaches to alc. sweetspotting of dealcoholized wines were evaluated, together with two methods of statistical anal., chi-squared goodness of fit and one proportion tests.

de Andrade Neves, Nathalia published the artcileChemical composition of jabuticaba (Plinia jaboticaba) liquors produced from cachaca and cereal alcohol, SDS of cas: 106-32-1, the main research area is Plinia jaboticaba liquor cachaca cereal alc volatile composition.

Jabuticaba (Plinia jaboticaba (DC) Berg.) is considered one of the main Brazilian sources of anthocyanins. It is widely recognized and popular, with its consumption occurring in fresh forms and through processed products. Although popular, jabuticaba liquors are handmade, on a small-scale, with little quality control and a lack of standardization. This study aimed to evaluate the effect of the ethanol source (cachaca and cereal alc.) on the chem. characteristics of jabuticaba liquors. The beverages were evaluated considering the contents of sugars, ethanol, anthocyanins, ellagic acid, amino acids, biogenic amines, organic acids, and volatile composition The liquors showed similar chem. compositions, which differs from the content of anthocyanins and the volatile composition The liquor made from cachaca showed a greater complexity of aroma, including terpenes and volatile phenolic compounds, and a higher d.p. of anthocyanins. This study is the first published for jabuticaba liquors.

Gardoni, E. published the artcileBiological deacidification strategies for white wines, Computed Properties of 106-32-1, the main research area is biol deacidification white wine.

Traditionally, the use of malolactic fermentation gives rise to microbiol. stable wines. However, malolactic fermentation is not free from possible collateral effects that can take place under specific scenarios. The present work tests the influence of different biol. deacidification strategies on the volatile and non-volatile components of white must from Germany. The study compared mixed cultures of Lachancea thermotolerans and Schizosaccharomyces pombe and a pure culture of Sc. pombe to the classical biol. deacidification process performed by lactic acid bacteria. Strains of Oenococcus oeni and Lactiplantibacillus plantarum were co- or sequentially inoculated with S. cerevisiae to carry out malolactic fermentation Different fermentation treatments took place at a laboratory scale of 0.6 L in vessels of 0.75 L. The instrumental techniques Fourier-transform mid-IR spectroscopy (FT-MIR), high performance liquid chromatog. (HPLC) and gas chromatog.-mass spectrometry (GC-MS) were used to evaluate different chem. parameters in the final wines. The results showed the ability of Sc. pombe to consume malic acid in combination with L. thermotolerans without using S. cerevisiae or lactic acid bacteria. Fermentations involving Sc. pombe consumed all the malic acid, although they reduced the concentrations of higher alcs., fatty acids and acetic acid. Simultaneous alc. and malolactic fermentations reduced malic acid by about 80%, while classical malolactic fermentation reduced it by 100%. Fermentations involving L. thermotolerans produced the highest lactic acid, ester and glycerol concentrations
