Escribano-Viana, Rocio published the artcileDo non-Saccharomyces yeasts work equally with three different red grape varieties, Product Details of C6H12O3, the main research area is Lachancea Torulaspora Tempranillo Grenache wine Metschnikowia malolactic fermentation inoculation.

The present study aimed to investigate the oenol. changes induced by non-Saccharomyces yeasts in three red grape varieties from the Rioja Qualified Designation of Origin. Pilot plants fermentation of three different varieties, were conducted following early inoculations with Metschnikowia pulcherrima and with mixed inoculum of Lachancea thermotolerans-Torulaspora delbrueckii from La Rioja and compared to a wine inoculated with Saccharomyces cerevisiae. The microbiol. and physicochem. characteristics of vinifications were analyzed. Results showed that most of the variations due to inoculation strategies were observed in Tempranillo just after the alc. fermentation, probably because of the better adaptation of the inocula to the must’s oenol. properties. Finally, after the malolactic fermentation the inoculation with the mix of Lachancea thermotolerans and Torulaspora delbrueckii caused more changes in Tempranillo and Grenache wines while the early inoculation with Metschnikowia pulcherrima had more effects on Grenache wines. Therefore, the study was aimed to identify the fermentation effects of each inoculation strategy by using different non-Saccharomyces yeasts and different grape varieties.

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.

Duran-Soria, Sara published the artcileExploring Genotype-by-Environment Interactions of Chemical Composition of Raspberry by Using a Metabolomics Approach, SDS of cas: 140-11-4, the main research area is Rubus idaeus genotype chem composition metabolomics; anthocyanins; berry; ellagitannins; environment; flavor; fruit quality; nutritional value; volatiles.

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.

Li, Yue-Qi published the artcileBiomass suppression of Hanseniaspora uvarum by killer Saccharomyces cerevisiae highly increased fruity esters in mixed culture fermentation, SDS of cas: 106-32-1, the main research area is biomass Hanseniaspora uvarum Saccharomyces cerevisiae fruity ester culture fermentation.

Hanseniaspora uvarum strain Yun268 was inoculated with Saccharomyces cerevisiae strains of different antagonistic abilities (RV002 and RV171) to evaluate fruity ester production in mixed fermentation Co-inoculation (CI) and sequential inoculation (SI) of two yeast species were performed in synthetic must and in Granoir winemaking. Fermentation kinetics, the formation of yeast biomass and fruity esters were monitored during fermentation, and the aroma attributes of the final wines were quantified by trained panelists. Results showed that killer S. cerevisiae suppressed biomass of Yun268 more than common S. cerevisiae, especially in CI treatment. Higher concentration of medium chain fatty acids was associated with the higher biomass suppression of H. uvarum in CI with killer S. cerevisiae, which resulted in the increased formation of fruity esters, but effectively restricted the production of Et acetate. However, more biomass and longer survival time of H. uvarum in SI considerably increased volatile acidity (3-fold higher than that in single fermentation), which delayed the reproduction of S. cerevisiae temporarily, and elevated the levels of Et acetate. Winemaking confirmed that the co-culture of H. uvarum and killer S. cerevisiae highly improved fruity aromas, which was due to the increase in ester production, especially medium chain fatty acid Et esters.

Zhang, Yu published the artcileCorrelation between the quality and microbial community of natural-type and artificial-type Yongchuan Douchi, Formula: C9H18O2, the main research area is fermentation food Yongchuan Douchi microbial community.

Yongchuan douchi is a traditional fermented food in China. This study investigated the microbial community of two major types (Natural and artificial) of Yongchuan douchi, and their influences on quality. The results found that natural-type douchi had significantly better quality in its physicochem. properties such as higher amino nitrogen, darker color, and higher umami amino acids after post-fermentation (p < 0.05). A total of 58 volatile components were found in natural-type douchi compared to artificial-type with 42 identified. Microbial anal. found that natural-type douchi had the richness and diversity of the bacterial (fungus) community. However, artificial-type douchi was high in Candida genera may associated with its bitter after taste compared to natural-type. Following post-fermentation, natural-type douchi had higher abundance of Bacillus sp., Enterobacter sp., and Pseudomonas sp., while Bacillus sp., Weissella sp., and Aspergillus sp. compared to artificial-type douchi. Correlation anal. showed that physicochem. properties and sensory quality could be correlated pos. or neg. with the microbial composition during the last stage of post-fermentation In conclusion, the zhiqu process significantly affected the final quality of the two types of Yongchuan douchi as evidenced by the microbial composition in the post-fermentation process.

Pereira, Catarina published the artcileRevealing the yeast modulation potential on amino acid composition and volatile profile of Arinto white wines by a combined chromatographic-based approach, Recommanded Product: Ethyl nonanoate, the main research area is Yeasts Arinto wine Amino acids Volatile compound aroma; Amino acids; Arinto wine; Volatile compounds; Wine aroma; Yeasts.

The importance of yeasts in aroma production during wine fermentation is a significant concern for obtaining a wine that appraises a broad number of consumers. For wine producers, wine aroma modulation is an essential issue where the yeasts used during the winemaking process represents a feasible way to improve the complexity and enhance wines specific characteristics. During the fermentation process of wines, yeasts convert grapes sugars into alc., carbon dioxide and a large number of secondary metabolites, depending on yeast metabolism, affecting the wine composition, namely its aroma and amino acids (AAs) composition So, the present work aims to study the effect of different Saccharomyces-type yeasts on the AAs composition and volatile profile of Arinto white wines. To pursue this goal, four white wines from Arinto grapes were fermented with three different com. yeasts (Saccharomyces bayanus EC1118, Saccharomyces cerevisiae CY3079, Saccharomyces bayanus QA23) and one Native yeast. Arinto wines AAs composition was quantified by HPLC-DAD, after a derivatization step to obtain the aminoenone derivatives The volatile content of Arinto wines was determined by GC/MS, after an HS-SPME extraction Results showed significant differences among the AAs content and volatile profile in the Arinto wines. The higher AAs content was found in the Arinto wines fermented with the CY3079 yeast (470.74 mg•L-1), and the lowest content of AAs in the Arinto wines fermented with EC1118 yeast (343.06 mg•L-1). Native yeast results in wines with a volatile profile richer in esters compared to the other sample wines. Principal component anal. (PCA) obtained with combined data of AAs and volatile compounds, after normalization, for each Arinto wine samples, shows a clear separation of wines fermented with Native and CY3079 yeasts in relation to QA23 and EC1118 fermented wines . The first and second principal components are responsible for 44.40% and 32.20%, resp., of the system′s variance, which clearly showed a differentiation among wines.
