Zhao, Jing published the artcileVolatile constituents and ellagic acid formation in strawberry fruits of selected cultivars, Category: esters-buliding-blocks, the main research area is volatile constituent ellagic acid formation strawberry fruit cultivar; Ellagic acid; Fragaria × ananassa; GC–MS; Sensory quality; Volatile profile.

Strawberries (Fragaria x ananassa Duch.) are considered a functional food and pleasing fruit in China, mainly because of their high concentration of ellagic acid (EA) and their aroma. A total of 127 volatile compounds were identified by HS-SPME-GC-MS. Changes in volatile constituents and EA were investigated in 50 strawberry cultivars in the red-ripening stage and in 6 cultivars, including ‘Benihoppe’, ‘Snow White’, ‘Yanli’, ‘Kaorino’, ‘Tokun’, and ‘Xiaobai’, at four developmental stages. The results indicated that the components and amounts of volatile compounds and EA markedly varied among and within cultivars. Through multivariate statistical anal. of the volatile compounds, 50 cultivars were divided into 4 clusters. Aromatic components that affected the cluster formation of cultivars were detected. Volatile compounds varied quant. among the 6 varieties during the developmental stages, and distinct changes were observed in both red-turning fruits and red-ripening fruits compared with white fruits. Except for ‘Xiaobai’, which showed the highest EA content at the red-ripening stage, the other 5 cultivars exhibited the highest EA level at the large green fruit stage. Partial least squares-discriminant anal. (PLS-DA) of the profiles of volatile compounds indicated that large green fruits were characterized by EA and aldehydes; white fruits were characterized by ketones and alkanes; and red-ripening fruits were characterized by esters, acids, furans, and alcs. The results contribute new and important information to breeding programs and the desirable cultivation of strawberry production

Zhang, Xiao published the artcileComparative evaluation of the effects of natural and artificial inoculation on soybean paste fermentation, Related Products of esters-buliding-blocks, the main research area is soybean paste natural artificial inoculation fermentation.

Soybean pastes fermented with natural (NIS) and artificial (AIS) inoculation were prepared to evaluate their fermentation characteristics, flavor compounds and microbial community compositions across an entire fermentation period. The results showed that the initial concentrations of free amino acids and aroma compounds were higher in NIS than in AIS, whereas it was opposite at the end of fermentation A larger variation of flavor compounds was observed in AIS, which was associated with higher level of microbial metabolism during AIS fermentation Penicillium and Tetragenococcus were the dominant microbial genera in NIS, while Aspergillus and Pediococcus were predominant in AIS. Correlation anal. of flavor compounds and microbial community dynamics during NIS and AIS fermentation revealed the specific role of microbial taxa in metabolite transformations. Pediococcus acidilactici could be the key microorganism strongly associated with 23 flavor compounds during AIS fermentation Further, Aspergillus oryzae and Pediococcus acidilactici were primarily linked to amino acid metabolism in AIS, whereas Penicillium and Yaniella were found associated with aroma compounds, Tetragenococcus_sp_JNURIC_D6 and Candida solani with that of organic acids in NIS. These findings provide substantial data on the development of flavor-enhancing fermentation starter culture and the better control of flavor ripening in soybean paste production

Liu, Jian published the artcileCharacterization of major properties and aroma profile of kiwi wine co-cultured by Saccharomyces yeast (S. cerevisiae, S. bayanus, S. uvarum) and T. delbrueckii, Computed Properties of 106-32-1, the main research area is Saccharomyces Torulaspora kiwi wine aroma flavor.

The effect of different yeast strains on the quality of kiwi wine was investigated by polyphase determine approaches in the present research. The influence of co-culture and inoculation sequence on the quality was also explored simultaneously. Results suggested that the characteristics of the kiwi wine were affected by the metabolic characteristic of strains. The flavor content and their flavor profile of samples fermented by co-culturing of strain among species, genus, and families. When Saccharomyces bayanus (Y5 or Y6) co-cultured with Torulaspora delbrueckii Y7, the ratio of phenethyl alc. increased, but that of octanoic acid and Et octanoate decreased significantly. The odor activity value (OAV) of Et octanoate and Et hexanoate was increased by co-culturing Saccharomyces with T. delbrueckii, and that of decanal and terpinen-4-ol was enhanced by co-culturing of different strains of Saccharomyces. It was an excepting process to obtain high quality of kiwi wine by co-culturing technol. of yeasts, and was very effective to optimize the process by polyphase anal. approaches.

Sun, Xuefei published the artcileProduction of alcohol-free wine and grape spirit by pervaporation membrane technology, Quality Control of 106-32-1, the main research area is alc free wine grape spirit pervaporation membrane technol.

This study reports on production of alc.-free wine and grape spirit from red wine using pilot-scale pervaporation membrane equipment. The ethanol and aroma substances were concentrated from the wine via an organophilic pervaporation membrane, which were further processed by the membrane to obtain an ethanol content above 50 volume%. The separation performance for ethanol/water and red wine was compared to show that fouling existed when processing the red wine, and the 1st-stage permeate was found to be an excellent cleaning agent that can recover 99.15% of the initial flux. The results of aroma anal. showed that 65-70 wt% of the aroma substances existed in the permeate of pervaporation, which exhibited better smell and taste than traditional distilled liquor. The membrane performance was stable for the separation of red wine during 180 days of continuous operation. Though the investment and operating cost of pilot-scale equipment are relatively high, remuneration can be greatly improved by the utilization of alc.-free wine and grape spirit.

Zhang, Chuang published the artcileExploring the effects of microencapsulation on odour retention of fermented noni juice, HPLC of Formula: 106-32-1, the main research area is fermented noni juice microencapsulation volatile profile.

The key volatiles of fermented noni juice (FNJ) were identified, and the effect of microencapsulation (via spray drying and freeze drying) on the volatile profile of FNJ powders was investigated. Results showed that hexanoic acid was the major contributor to the unpleasant odor of FNJ. Both drying methods significantly reduced (p < 0.05) the retention of volatiles, and changed the volatile profile of the resulting powders. Comparing the two methods, volatile retention in the spray-dried powder was lower, and was neg. affected by the increase of drying air temperature (p < 0.05). The odor activity values (OAVs) of key volatiles decreased after microencapsulation, however, most of them were still present, and contributed to the overall odor of the powders. This research has provided qual. and quant. data on the volatiles of FNJ, and explored for the first time, the influence of microencapsulation on the volatile characteristics and retention in powders.

Wang, Dong published the artcileImpact of drying method on the evaluation of fatty acids and their derived volatile compounds in ‘thompson seedless’ raisins, Related Products of esters-buliding-blocks, the main research area is fatty acids volatile compound raisin drying method; GC/MS; UFAO-derived compounds; air- and sun-drying; fatty acids; raisins.

Air- and sun-dried raisins from Thompson Seedless (TS) grapes were analyzed under GC/MS to evaluate fatty acids (FAs) and their derived volatile compounds, coming from unsaturated fatty acids oxidation A total of 16 FAs were identified in TS raisins, including 10 saturated fatty acids (SFAs) and 6 unsaturated fatty acids (USFAs). The contents of C18:0, C15:0, and C16:0 among SFAs and C18:3, C18:2 and C18:1 in USFAs were significantly higher. Furthermore, USFAs such as C16:1 and C20:1 were only identified in air-dried raisins. The principal component anal. showed the increased content of FAs and FA-derived compounds were in air-dried and sun-dried raisins, resp. Among FA-derived compounds, 2-pentyl furan, 3-octen-2-one, 1-hexanol and heptanoic acid were more potent. This study shows that air-drying is more favorable for the production of fatty acids (SFAs and USFAs), whereas sun-drying is more advantageous in terms of fatty acid-derived volatiles.

Wang, Rui published the artcileBiotransformation of green tea (Camellia sinensis) by wine yeast Saccharomyces cerevisiae, Related Products of esters-buliding-blocks, the main research area is Camellia Saccharomyces biotransformation volatile compound; antioxidant capacity; fermentation; flavor; polyphenols; sensory.

Wine yeast Saccharomyces cerevisiae 71B was used in fermentation of green tea to modulate the volatiles and nonvolatiles. After fermentation, higher alcs., esters, and acids, such as isoamyl alc., isobutanol, Et octanoate, Et decanoate, octanoic, and decanoic acids were generated. Some key aroma compounds of tea including linalool, hotrienol, dihydroactinidiolide, and 2-phenylethanol increased significantly. Among these compounds, linalool and 2-phenylethanol increased by 1.3- and 10-fold, resp., which impart floral and fruity notes to fermented green tea. Alkaloids including caffeine, theobromine, and theophylline were reduced significantly after fermentation, while the most important free amino acid in tea, theanine, was not metabolized by S. cerevisiae. Tea catechins decreased whereas gallic and caffeic acids increased significantly, resulting in the unchanged antioxidant capacity of the fermented green tea. Hence, this work highlighted the potential of using S. cerevisiae to modulate green tea aroma and nonvolatiles. Practical Application : A novel fermented tea is produced by yeast fermentation Saccharomyces cerevisiae led to significant changes in tea volatiles and nonvolatiles. Antioxidant capacity remained stable after fermentation

Huang, Ling published the artcileComposition of Pinot Noir Wine from Grapevine Red Blotch Disease-Infected Vines Managed with Exogenous Abscisic Acid Applications, COA of Formula: C10H20O2, the main research area is Pinot Noir wine grapevine red blotch disease abscisic acid; exogenous abscisic acid application; grapevine red blotch disease; untargeted LC-HRMS/MS analysis; vineyard management; wine composition; wine volatile compounds.

Grapevine red blotch disease (GRBD) has neg. effects on grape development and impacts berry ripening. Abscisic acid (ABA) is a plant growth regulator involved in the initiation of berry ripening. Exogenous abscisic acid application was compared to an unsprayed control on GRBD-pos. Pinot noir vines during two vintages, and the total monomeric anthocyanin, total phenolics, phenolic composition, and volatile profile were measured in wines. In addition, untargeted metabolites were profiled using high-resolution LC-MS/MS. Results showed that the wine composition varied by vintage year and was not consistent with ABA application. Wines from the ABA treatment had a lower total anthocyanin and total phenolic content in one year. The untargeted high-resolution LC-MS/MS anal. showed a higher abundance of phenolic compounds in ABA wines in 2019, but lower in 2018. The wine volatile compounds of ABA treatments varied by vintage. There were higher levels of free β-damascenone, β-ionone, nerol, and several fermentation-derived esters, acids, and alcs. in ABA wines, but these were not observed in 2019. Lower 3-isobutyl-2-methoxypyrazine (IBMP) was also observed in wines with ABA treatment in 2019. The results demonstrated that ABA application to the fruit zones did not consistently mitigate the adverse impacts of GRBD on Pinot noir wines.
