Kong, Cai-Lin published the artcileFlavor modification of dry red wine from Chinese spine grape by mixed fermentation with Pichia fermentans and S. cerevisiae, Name: 3-(Methylthio)propan-1-ol, the main research area is Pichia Saccharomyces Vitis dry red wine flavor mixed fermentation.

Mixed fermentation of Pichia fermentans and Saccharomyces cerevisiae was designed to circumvent the problem of weak aroma in Chinese spine grape wines. Spine grape, “”Xiang Pearl””, was used for wine production by red wine-making processes. Physicochem. indexes were measured using titratable and spectroscopic methodologies. Volatiles were quantified by SPME-GC-MS, and aroma attributes were analyzed by trained panelists. Results showed mixed fermentation benefited color properties by improving total anthocyanin, polymeric anthocyanin, and total tannin contents. The content of varietal compounds, except those of thiols, were reduced, whereas fermentative compounds contents, especially those of higher alcs., esters, and phenylethyls, were increased by mixed fermentation Sensory anal. showed mixed fermentation enhanced fruity and floral traits in wine; this was confirmed by math. regression showing elevated levels of fermentative volatiles dominated the contribution to pleasant aroma, whereas reduced content of varietal compounds, with the exception of thiols, correlated neg. with favorable characteristics.

Minh, Nguyen Phuoc published the artcileTechnical parameters affecting the spray drying of roselle (Hibiscus sabdariffa) powder, Synthetic Route of 64519-82-0, the main research area is tech parameter spray drying roselle powder.

Roselle (Hibiscus sabdariffa) was a member of Malvaceae family. Its calyxes had bright red color due to presence of anthocyanin with an excellent antioxidant property. Raw roselle (Hibiscus sabdariffa L.) calyx was highly perishable due to its high moisture content. In order to diversify products from this plant, this research evaluated the possibility of spray drying for roselle extract into dried powder for long-term consumption. We focused on the effect of sugar alcs. (mannitol, sorbitol, isomalt, xylitol, erythritol) at 8%, carrier agents (maltodextrin, gum arabic, glutinous starch, whey protein concentrate, CM-cellulose) at 12%, operating parameters of spray dryer (inlet/outlet air temperature, feed rate) on physicochem. quality (bulk d., solubility, total phenolic content, total flavonoid content, anthocyanin content) of rosselle powder. Results showed that the optimal spray drying variables for rosselle powder should be 8% isomalt, 12% whey protein concentrate, inlet/ outlet air temperature 140/85°C/°C, feed rate 12 mL/min. Based on these optimal conditions, the highest physicochem. attributes of the dried roselle calyx powder would be obtained.

Darici, Merve published the artcileChemical and sensory characterization of Kalecik Karasi wines produced from two different regions in Turkey using chemometrics, Product Details of C4H10OS, the main research area is grape variety wine chemometric aroma.

Kalecik Karasi (KK) is one of the important native grape varieties of Turkey used in red wine production As an extension of a previous project that profiled the sensory characteristics of KK wines from different geog. regions of Turkey, this study aimed to investigate the chem. composition and sensory properties of KK wines belonging to different vintages from two different regions (Kalecik/Ankara and Gueney/Denizli) using the chemometric technique. Identification and quantification of aroma, aroma-active compounds, and sensory evaluations were carried out by GC/MS/FID, GC-O, and Descriptive Analyses. PLSR was used for determining the correlation between chem. and sensory data. A total of 26 aroma-active compounds have been identified for both regions. Based on PLSR, red fruit attribute in wines was pos. correlated with isoamylacetate, ethyl-hexadecanoate, ethyl-4-hydroxybutanoate, and 2-phenylethyl acetate. Dried fruit attribute has shown a significant pos. correlation with ethyl-2-methyl-propanoate, ethyl-2-methylbutanoate, and ethyl-3-methylbutanoate. The cotton candy attribute was pos. correlated with 2-phenylethanol, 2-phenylethyl acetate, ethyl-4-hydroxybutanoate, and gamma-butyrolactone. This is the first study in the literature to determine the correlation between chem. and sensory data in Kalecik Karasi wines. The study determined that common aroma descriptors of KK wines include red fruit (strawberry, raspberry, and apple), dried fruit, cotton candy, flower, and spice (sweet spices and nutmeg) odors. The characterization of the wines using chemometrics is an important tool. The findings obtained may constitute a source for quality Kalecik Karasi wines in transition to the Geog. Indication system.

Cautela, Domenico published the artcileThe ancient neapolitan sweet lime and the calabrian lemoncetta locrese belong to the same citrus species, HPLC of Formula: 124-76-5, the main research area is citrus flavonoid volatile organic compound; Mediterranean sweet lime; Neapolitan limmo; Neapolitan “four citrus fruits” liqueur; agrobiodiversity; lemoncetta Locrese; taxonomy.

“”Neapolitan limmo”” is an ancient and rare sweet Mediterranean lime, now almost extinct but used until a few decades ago for the production of a fragrant liqueur called the “”four citrus fruits””. The objective of this work was to compare, through the use of chem. (flavonoids, volatile organic compounds, and chiral compounds) and mol. (DNA fingerprint based on RAPD-PCR) markers, the residual population of Neapolitan limmo with other populations of sweet limes, identified in Calabria and known as “”lemoncetta Locrese””. We report for the first time specific botanical characteristics of the two fruits and unequivocally show that the ancient sweet Mediterranean limes Neapolitan limmo and lemoncetta Locrese are synonyms of the same Citrus species. Owing to the biodiversity conserved in their places of origin, it will now be possible to recover, enhance and implement the use of this ancient sweet lime for agro-industrial purposes.

Martinelli, F. published the artcileEffects of irrigation on fruit ripening behavior and metabolic changes in olive, Safety of (3R,4R,5R)-6-(((2S,3R,4S,5S,6R)-3,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexane-1,2,3,4,5-pentaol, the main research area is olive irrigation fruit ripening metabolism.

Olive (Olea europaea, cv Leccino) fruits grown under different water regimes were analyzed by metabolomics and specific transcript accumulation analyses. The fruit from non-irrigated (rain-fed) and irrigated trees cultivated under field conditions, with a seasonal water amount equivalent to the calculated crop evapotranspiration (ETc) was compared in the last developmental phase and, in particular, at com. harvest. Metabolomics (GC-MS) anal. identified several hundred metabolites in ripe mesocarp, 46 of which showed significantly different contents in the rain-fed and irrigated samples. Some compounds involved in primary metabolism (carbohydrates, amino acids, organic acids) and secondary metabolism (squalene, simple phenols) appeared to be more abundant when irrigation was performed. Higher levels of total polyphenol were observed in the rain-fed fruit, which at ripening showed an increase in anthocyanin concentration Thus, ripening in olives is affected by irrigation. In addition, expression analyses of three key polyphenol biosynthetic genes (phenylalanine ammonia lyase (PAL), chalcone synthase (CHS), dihydroflavonol reductase (DFR)) and two genes involved in triterpenoid metabolism (β-amyrin synthase and cycloartenol synthase) were also performed. The analyzed genes showed different expression patterns throughout ripening, and the resulting PAL, DFR and β-amyrin synthase transcript accumulation was found to be affected by the different water regimes at specific stages of fruit development.

Chu, Lulu published the artcileChemical composition, antioxidant activities of polysaccharide from Pine needle (Pinus massoniana) and hypolipidemic effect in high-fat diet-induced mice, Synthetic Route of 59-23-4, the main research area is Pinus needle polysaccharide antioxidant hypolipidemic high fat diet; Antioxidant activities; Chemical composition; Hypolipidemic effect; Pine needle polysaccharide.

The aim of this study is to investigate hypolipidemic and antioxidant effects of Pine needle polysaccharide (PNP) from Pinus massoniana in high-fat diet (HFD)-induced mice. PNP could significantly improve the serum lipid levels (total cholesterol, triacylglycerols, high-d. lipoprotein cholesterol, low-d. lipoprotein cholesterol), enhance the antioxidant enzymes levels (total antioxidant capability, superoxide dismutase, glutathione peroxidase, catalase), and decrease malondialdehyde (MDA) content in HFD-induced mice. PNP exhibited distinct antioxidant ability on the superoxide anions, 1, 1-diphenyl-2-picrylhydrazyl (DPPH) and ferric ion reducing antioxidant power (FRAP) in vitro. The average mol. weight (Mw) of PNP was 6.17 × 105 Da, and mainly of fucose, arabinose, galactose, glucose, galacturonic acid. These results suggested that PNP might be used as functional foods and natural drugs in enhancing antioxidant ability and alleviating the hyperlipidemia.

Sampson, Connor D. D. published the artcileThermostability-based binding assays reveal complex interplay of cation, substrate and lipid binding in the bacterial DASS transporter, VcINDY, Recommanded Product: (S)-2-hydroxysuccinic acid, the main research area is thermostability cation lipid binding DASS transporter; lipids; membrane proteins; membranes; molecular interactions; transport.

The divalent anion sodium symporter (DASS) family of transporters (SLC13 family in humans) are key regulators of metabolic homeostasis, disruption of which results in protection from diabetes and obesity, and inhibition of liver cancer cell proliferation. Thus, DASS transporter inhibitors are attractive targets in the treatment of chronic, age-related metabolic diseases. The characterization of several DASS transporters has revealed variation in the substrate selectivity and flexibility in the coupling ion used to power transport. Here, using the model DASS co-transporter, VcINDY from Vibrio cholerae, we have examined the interplay of the three major interactions that occur during transport: the coupling ion, the substrate, and the lipid environment. Using a series of high-throughput thermostability-based interaction assays, we have shown that substrate binding is Na+-dependent; a requirement that is orchestrated through a combination of electrostatic attraction and Na+-induced priming of the binding site architecture. We have identified novel DASS ligands and revealed that ligand binding is dominated by the requirement of two carboxylate groups in the ligand that are precisely distanced to satisfy carboxylate interaction regions of the substrate-binding site. We have also identified a complex relationship between substrate and lipid interactions, which suggests a dynamic, regulatory role for lipids in VcINDY′s transport cycle.

De Almeida E Silva, Beatriz published the artcileInteraction between mycorrhizal fungi and Meloidogyne javanica on the growth and essential oil composition of basil (Ocimum basilicum), Quality Control of 124-76-5, the main research area is Meloidogyne Ocimum mycorrhizal fungi essential oils.

Plant-parasitic nematodes and arbuscular mycorrhizal fungi (AMF) have been reported to alter the yield and chem. composition of basil (Ocimum basilicum) essential oil. The aim of this study was to evaluate the effectiveness of AMF to control the root-knot nematode Meloidogyne javanica in basil and to investigate the effects of nematode-AMF interactions on plant growth, phosphorus (P) absorption, and essential oil composition The experiment was conducted under greenhouse conditions following a completely randomized 3 x 2 factorial (two fungal species and an uninoculated control x inoculated and uninoculated seedlings) arrangement with 10 replicates. Substrates were inoculated with Claroideoglomus etunicatum, Rhizophagus clarus, or no fungi (control) and sown with basil seeds. After 20 days, half of the seedlings were inoculated with 4,000 M. javanica eggs. After 60 days, the vegetative parameters, P absorption, essential oil composition, nematode population d., AMF root-colonization efficiency, and AMF spore d. were determined The presence of AMF increased the basil’s fresh weight and ability to absorb P, while reducing the M. javanica reproduction In total, 21 compounds were identified in basil essential oil, the concentrations of which varied according to the treatments. The major components were eucalyptol, linalool, eugenol, β-elemene, trans-α-bergamotene, and τ-cadinol. Inoculation with AMF decreased the linalool levels but increased the amount of eucalyptol. Mycorrhizal plants showed increased shoot height, P uptake, and essential oil yield and a decreased nematode population d. in their roots.

Hogewoning, Sander W. published the artcileCAM-physiology and carbon gain of the orchid Phalaenopsis in response to light intensity, light integral and carbon dioxide, SDS of cas: 97-67-6, the main research area is orchid Phalaenopsis light intensity carbon dioxide; Rubisco; citrate; crassulacean acid metabolism; malate; phosphoenolpyruvate carboxylase (PEPC).

The regulation of photosynthesis and carbon gain of crassulacean acid metabolism (CAM) plants has not yet been disclosed to the extent of C3-plants. In this study, the tropical epiphyte Phalaenopsis cv. “”Sacramento”” was subjected to different lighting regimes. Photosynthesis and biochem. measuring techniques were used to address four specific questions: (1) the response of malate decarboxylation to light intensity, (2) the malate carboxylation pathway in phase IV, (3) the response of diel carbon gain to the light integral and (4) the response of diel carbon gain to CO2. The four CAM-phases were clearly discernable. The length of phase III and the malate decarboxylation rate responded directly to light intensity. In phase IV, CO2 was initially mainly carboxylated via Rubisco. However, at daylength of 16 h, specifically beyond ±12 h, it was mainly phosphoenolpyruvate carboxylase (PEP-C) carboxylating CO2. Diel carbon gain appeared to be controlled by the light integral during phase III rather than the total daily light integral. Elevated CO2 further enhanced carbon gain both in phase IV and phase I. This establishes that neither malate storage capacity, nor availability of PEP as substrate for nocturnal CO2 carboxylation were limiting factors for carbon gain enhancement. These results advance our understanding of CAM-plants and are also of practical importance for growers.
