On June 30, 2022, Romano, Raffaele; De Luca, Lucia; Aiello, Alessandra; Rossi, Danilo; Pizzolongo, Fabiana; Masi, Paolo published an article.Reference of Methyl N-Methylanthranilate The title of the article was Bioactive compounds extracted by liquid and supercritical carbon dioxide from citrus peels. And the article contained the following:

This work investigated the extraction of bioactive compounds from citrus peels, an agri-food waste. Carbon dioxide (CO2), an eco-friendly solvent, was used under liquid and supercritical conditions to perform the extractions from orange, tangerine and lemon peels. The possibility of using ethanol as a cosolvent at small percentages up to 20% was also studied. The extraction yield, total polyphenolic content, individual polyphenolic profile, antiradical activity and volatile organic compounds of the extracts were evaluated. The highest yields were obtained when 20% ethanol was used as a cosolvent in both liquid (at 20 MPa and 20°C) and supercritical (at 30 MPa and 60°C) CO2 extraction In addition, the extracts obtained with liquid CO2 + 20% ethanol showed the highest content of naringin (35.26, 44.05 and 19.86 mg g-1 in orange, tangerine and lemon peel extracts, resp.) and terpenes, in particular limonene. This type of extract also showed the highest antiradical activity (31.78-59.51μmolTE g-1) as measured by both ABTS·+ and DPPH·. These findings show that the extraction with a liquid CO2 and ethanol mixture could be a valid alternative to traditional solvent extraction using 80% less organic solvent and producing extracts with high antiradical capacity and rich in volatile organic compounds The experimental process involved the reaction of Methyl N-Methylanthranilate(cas: 85-91-6).Reference of Methyl N-Methylanthranilate

And the article contained the following:

The effects of lactic acid bacteria strains from Lactiplantibacillus, Lactobacillus, Fructobacillus and Weissella on the chem. composition and sensory characteristics of goji berry juice were evaluated. The goji berry juice was fermented for 24 h at 30°C and aged 21 days at 4°C. All studied strains showed good growth in goji berry juice. The chem. components (93 volatile compounds, seven non-volatile acids and two sugars) exhibited 8 evolution groups, and different strains resulted in different flavor features. The juices fermented with L. plantarum or L. acidophilus were described with ‘honey’, ‘wild jujube’ odors and ‘sour’ taste in Flash-Profile test, whereas the juices with L. helveticus presented ‘goji berry’, ‘floral’ and sweetness, and the juices with F. fructosus or W. cibaria had ‘vinegar’ and sweetness. In a PLS regression model, the ‘goji berry’ odor correlated pos. with hexanal, (E)-2-hexenal, 5-ethylcyclopent-1-enecarboxaldehyde, benzaldehyde, 1-octen-3-ol, α-calacorene and neg. with acetoin and acetic acid. In this study, L. helveticus strain 6024 was more effectively able to retain or enrich the key compounds pos. associated with ‘goji berry’ note compared to other strains. This study enables more extensive utilization of goji berry in the food industry and helps to improve the flavor of goji berry products. The experimental process involved the reaction of Diethyl succinate(cas: 123-25-1).SDS of cas: 123-25-1

Wang, Jing; Ma, Yuwen; Sam, Faisal Eudes; Gao, Pingping; Liang, Lihong; Peng, Shuai; Li, Min published an article in 2022, the title of the article was The Impact of Indigenous Non-Saccharomyces Yeasts Inoculated Fermentations on ‘Semillon’ Icewine.Computed Properties of 123-25-1 And the article contains the following content:

The emerging low acidity in icewine grapes is becoming a major problem in producing quality icewine. Using non-Saccharomyces cerevisiae yeasts in fermentation can improve wine’s organoleptic characteristics and aromatic quality. This study evaluated two indigenous non-Saccharomyces cerevisiae yeasts, Lachancea thermotolerans (LT-2) and Torulaspora delbrueckii (TD-3), for their ability to improve the acidity and quality of ‘Semillon’ icewine. Five different inoculation schemes were implemented, including a single inoculation of S. cerevisiae (SC), L. thermotolerans (LT), and T. delbrueckii (TD); the sequential inoculation of L. thermotolerans, followed by S. cerevisiae after 6 days (L-S); and the sequential inoculation of L. thermotolerans, followed by T. delbrueckii after 6 days (L-D). The results showed that, during sequential fermentation (L-S and L-D), the presence of S. cerevisiae or T. delbrueckii slightly restrained the growth of L. thermotolerans. Single or sequential inoculation with L. thermotolerans and T. delbrueckii significantly reduced the amount of volatile acidity and increased the glycerol content. Furthermore, fermentations involving L. thermotolerans produced relevant amounts of lactic acid (2.04-2.2 g/L) without excessive deacidification of the icewines. Addnl., sequential fermentations increased the concentration of terpenes, C13-norisoprenoid compounds, and phenethyl compounds A sensory anal. also revealed that sequentially fermented icewines (L-S and L-D) had more fruity and floral odors and aroma intensity. This study highlights the potential application of L. thermotolerans and T. delbrueckii in sequential fermentation to improve the icewine quality. The experimental process involved the reaction of Diethyl succinate(cas: 123-25-1).Computed Properties of 123-25-1

On June 19, 2020, Yang, Zeyu; Ye, Wenjie; Xie, Youyu; Liu, Qinghai; Chen, Rong; Wang, Hualei; Wei, Dongzhi published an article.Application of 3976-69-0 The title of the article was Efficient Asymmetric Synthesis of Ethyl (S)-4-Chloro-3-hydroxybutyrate Using Alcohol Dehydrogenase SmADH31 with High Tolerance of Substrate and Product in a Monophasic Aqueous System. And the article contained the following:

Bioredns. catalyzed by alc. dehydrogenases (ADHs) play an important role in the synthesis of chiral alcs. However, the synthesis of Et (S)-4-chloro-3-hydroxybutyrate [(S)-CHBE], an important drug intermediate, has significant challenges concerning high substrate or product inhibition toward ADHs, which complicates its production Herein, we evaluated a novel ADH, SmADH31, obtained from the Stenotrophomonas maltophilia genome, which can tolerate extremely high concentrations (6 M) of both substrate and product. The coexpression of SmADH31 and glucose dehydrogenase from Bacillus subtilis in Escherichia coli meant that as much as 660 g L-1 (4.0 M) Et 4-chloroacetoacetate was completely converted into (S)-CHBE in a monophasic aqueous system with a >99.9% ee value and a high space-time yield (2664 g L-1 d-1). Mol. dynamics simulation shed light on the high activity and stereoselectivity of SmADH31. Moreover, five other optically pure chiral alcs. were synthesized at high concentrations (100-462 g L-1) as a result of the broad substrate spectrum of SmADH31. All these compounds act as important drug intermediates, demonstrating the industrial potential of SmADH31-mediated bioredns. The experimental process involved the reaction of (R)-Methyl 3-hydroxybutanoate(cas: 3976-69-0).Application of 3976-69-0

Gerocs, Annamaria; Nagy, Tibor; Nemes-Barnas, Katalin; Majer, Janos; Szoke, Barna Arpad; Kovago, Robert; Magalhaes, Frederico; Gibson, Brian; Szekeres, Andras; Juhasz, Akos; Posta, Katalin; Olasz, Ferenc published an article in 2022, the title of the article was Characterization of Saccharomyces Strains Isolated from “Keknyelu” Grape Must and Their Potential for Wine Production.Computed Properties of 123-25-1 And the article contains the following content:

Novel wine yeast strains have the potential to satisfy customer demand for new sensorial experiences and to ensure that wine producers have strains that can produce wine as efficiently as possible. In this respect, hybrid yeast strains have recently been the subject of intense research, as they are able to combine the favorable characteristics of both parental strains. In this study, two Saccharomyces “Keknyelu” grape juice isolates were identified by species-specific PCR and PCR-RFLP methods and investigated with respect to their wine fermentation potential. Physiol. characterization of the isolated strains was performed and included assessment of ethanol, sulfur dioxide, temperature and glucose (osmotic stress) tolerance, killer-toxin production, glucose fermentation ability at 16°C and 24°C, and laboratory-scale fermentation using sterile “Keknyelu” must. Volatile components of the final product were studied by gas chromatog. (GC) and mass spectrometry (MS). One isolate was identified as a S. cerevisiae × S. kudriavzevii hybrid and the other was S. cerevisiae. Both strains were characterized by high ethanol, sulfur dioxide and glucose tolerance, and the S. cerevisiae strain exhibited the killer phenotype. The hybrid isolate showed good glucose fermentation ability and achieved the lowest residual sugar content in wine. The ester production of the hybrid strain was high compared to the control S. cerevisiae starter strain, and this contributed to the fruity aroma of the wine. Both strains have good oenol. characteristics, but only the hybrid yeast has the potential for use in wine fermentation The experimental process involved the reaction of Diethyl succinate(cas: 123-25-1).Computed Properties of 123-25-1
