Aroma stability and sensory aspects of commercially produced orange juice: gas chromatography-olfactometry study was written by Kopuncova, Maria;Sadecka, Jana;Kolek, Emil;Dimitrov, Filip;Tobolkova, Blanka;Durec, Jan;Blasko, Jaroslav. And the article was included in Chemical Papers in 2022.Synthetic Route of C10H20O2 The following contents are mentioned in the article:

The effects of pasteurization and 4-mo storage on the aroma profile of orange juices with pulp that were fully processed and packed in inert nitrogen atm. were investigated within the span of 2 years (2018 and 2019). Headspace solid-phase microextraction, gas chromatog.-mass spectrometry, as well as gas chromatog. coupled to flame ionization detection and olfactometry, were used for extraction, and subsequent anal. of the odor-active volatiles. Observed changes in their odor intensity, including the formation of some off-flavors such as methional, furaneol, 4-vinylguaiacol and guaiacol, were not significant to that extent to lead to an evident worsening in the overall flavor of juices. Thus, the use of nitrogen atm. proved its ability to protect the organoleptic quality of juice from undesirable changes caused by oxidative load or acid-catalyzed reactions. Aroma profiles of fresh juices were considerably influenced by diverse climatic conditions, and different seasons of orange harvest in monitored years. Pasteurization and storage had lesser impact on the volatiles in 2018 as in 2019, probably due to the inter-annual variability in such parameters of juices as content of pulp and pH. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Synthetic Route of C10H20O2).

Octyl acetate (cas: 112-14-1) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Synthetic Route of C10H20O2

Development of a novel microwave distillation technique for the isolation of Cannabis sativa L. essential oil and gas chromatography analyses for the comprehensive characterization of terpenes and terpenoids, including their enantio-distribution was written by Micalizzi, Giuseppe;Alibrando, Filippo;Vento, Federica;Trovato, Emanuela;Zoccali, Mariosimone;Guarnaccia, Paolo;Dugo, Paola;Mondello, Luigi. And the article was included in Molecules in 2021.HPLC of Formula: 112-14-1 The following contents are mentioned in the article:

A microwave distillation method was optimized for the extraction and isolation of cannabis essential oil from fresh and dried hemp inflorescences. The developed method enabled us to obtain a distilled product rich in terpenes and terpenoid compounds, responsible of the typical and unique smell of the cannabis plant. The distillate from different hemp cultivars, including Kompolti, Futura 75, Carmagnola, Felina 32 and Finola were characterized by using a gas chromatograph equipped with both mass spectrometer and flame ionization detectors. In a single chromatog. run, the identity and absolute amounts of distilled compounds were determined Peak assignment was established using a reliable approach based on the usage of two identification parameters, named reverse match, and linear retention index filter. Absolute quantification (mg g^-1) of the analytes was performed using an internal standard method applying the flame ionization detector (FID) response factors according to each chem. family. An enantio-GC-MS method was also developed in order to evaluate the enantiomeric distribution of chiral compounds, an anal. approach commonly utilized for establishing the authenticity of suspicious samples. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1HPLC of Formula: 112-14-1).

Octyl acetate (cas: 112-14-1) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.HPLC of Formula: 112-14-1

Revealing compositional attributes of Glossostemon bruguieri Desf. root geographic origin and roasting impact via chemometric modeling of SPME-GC-MS and NMR metabolite profiles was written by Farag, Mohamed A.;Afifi, Sherif M.;Rasheed, Dalia M.;Khattab, Amira R.. And the article was included in Journal of Food Composition and Analysis in 2021.SDS of cas: 112-14-1 The following contents are mentioned in the article:

Glossostemon bruguieri Desf. (Moghat, Sterculiaceae), is a shrub well-known for its thick long-tapering dark colored roots, grown in the Middle East and North Africa. Studies on Glossostemon have focused on its nutritive value and health benefits attributed to its phenolic content with no extensive anal. of secondary metabolome. NMR metabolite fingerprinting of 12 G. bruguieri root specimens of different origins using 1D and 2D experiments identified 12 major primary and secondary metabolites. Orthogonal partial least squares-discriminant anal. (OPLS-DA) of NMR aromatic regions was competent in discriminating between roots origin based on moghatin and pinoresinol levels. Quantification of ¹H NMR spectra revealed enrichment of Siwa specimens in sugars i.e., sucrose and inositol (17.89 and 12.06μg/mg, resp.), as well as some secondary metabolites viz. moghatin, pinoresinol, takakin and fraxetin (7.73, 4.55, 3.81 and 3.03μg/mg, resp.), posing it for future incorporation in nutraceuticals. However, much less is known regarding aroma and roasting impact on root chem. composition Volatile profiles of 15 unroasted and roasted specimens were analyzed using headspace solid-phase microextraction coupled to mass spectrometry. 100 Volatile constituents were identified dominated by aldehydes, ethers and mono- and sesquiterpenes, whereas esters were abundant in roasted roots. OPLS-DA identified 2-ethyl-6-methylpyrazine and 5-methyl-2-furfural as roasting descriptors.

Identification of honey origin based on specific chem. markers is important for honey authentication. This study is aimed to differentiate Malaysian stingless bee honey from different entomol. origins (Heterotrigona bakeri, Geniotrigona thoracica and Tetrigona binghami) based on physicochem. properties (pH, moisture content, ash, total soluble solid and elec. conductivity) and volatile compound profiles. The discrimination pattern of 75 honey samples was observed using Principal Component Anal. (PCA), Hierarchical Clustering Anal. (HCA), Partial Least Square-Discriminant Anal. (PLS-DA), and Support Vector Machine (SVM). The profiles of H. bakeri and G. thoracica honey were close to each other, but clearly separated from T. binghami honey, consistent with their phylogenetic relationship. T. binghami honey is marked by significantly higher elec. conductivity, moisture and ash content, and high abundance of 2,6,6-trimethyl-1-cyclohexene-1-carboxaldehyde, 2,6,6-trimethyl-1-cyclohexene-1-acetaldehyde and Et 2-(5-methyl-5-vinyltetrahydrofuran-2-yl)propan-2-yl carbonate. Copaene was proposed as chem. marker for G. thoracica honey. The potential of different parameters that aid in honey authentication was highlighted.

Pears (Pyrus communis L.) cv. Packham′s Triumph are very traditional for human consumption, but pear is a highly perishable climacteric fruit with a short shelf-life affected by several diseases with a microbial origin. In this study, a protective effect on the quality properties of pears was evidenced after the surface application of chitosan-Ruta graveolens essential oil coatings (CS + RGEO) in four different concentrations (0, 0.5, 1.0 and 1.5 %, volume/volume) during 21 days of storage under 18 °C. After 21 days of treatment, a weight loss reduction of 10% (from 40.2 ± 5.3 to 20.3 ± 3.9) compared to the uncoated pears was evident with CS + RGEO 0.5%. All the fruits′ phys.-chem. properties evidenced a protective effect of the coatings. The maturity index increased for all the treatments. However, the pears with CS + RGEO 1.5% were lower (70.21) than the uncoated fruits (98.96). The loss of firmness for the uncoated samples was higher compared to the coated samples. The pears′ most excellent mech. resistance was obtained with CS + RGEO 0.5% after 21 days of storage, both for compression resistance (7.42 kPa) and force (22.7 N). Microbiol. studies demonstrated the protective power of the coatings. Aerobic mesophilic bacteria and molds were significantly reduced (in 3 Log CFU/g compared to control) using 15 μL/mL of RGEO, without affecting consumer perception. The results presented in this study showed that CS + RGEO coatings are promising in the post-harvest treatment of pears. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Safety of Octyl acetate).

Objective: In the present study, extracellular esterase from bacterial isolate Bacillus licheniformis was purified, characterized and used in the synthesis of octyl acetate. Methods: Purification of esterase from Bacillus licheniformis was achieved using Sephadex G-75 column chromatog. Gas chromatog. was used to analyze the octyl acetate synthesis. Results: The enzyme was salted out using ammonium sulfate precipitation and 60-70% saturation gave maximum specific activity of the enzyme during precipitation A purification fold of 6.46 and yield of 9.69% was achieved when esterase from Bacillus licheniformis was purified using Sephadex G-75 column chromatog. This showed that the enzyme was purified to homogeneity and it was a monomer with mol. weight of 42 kDa. Biochem. characterization of the enzyme revealed that it had optimum temperature of 45°C in 0.1 M Tris-HCl buffer of pH 8.0. On optimizing different parameters, such as molar ratio of reactants, incubation time, temperature, and amount of protein, the % yield of octyl acetate was found to be 77.3%. Conclusion: In this work, simple method was used to purify esterase and the enzyme was further used in producing esters/products of com. value within a reasonably short period of 12 h with a maximum yield of 77.3%. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1HPLC of Formula: 112-14-1).

Aroma is a key quality attribute of apples, making major contributions to com. value and consumer choice. However, the mechanism underlying mol. regulation of aroma formation genes and transcription factors remains poorly understood in apples. Here, we investigated the aroma volatile profiles of two apple varieties with distinctive flavors using headspace solid-phase microextraction (HS-SPME) combined with gas chromatog.-mass spectrometry (GC-MS). A total of 35 volatile compounds were identified in Granny Smith and Jonagold apples. Aldehydes were the most abundant volatiles contributing to the aroma in Granny Smith apple while esters were the dominant volatile compounds in Jonagold apple. In order to know more about the expression levels of aroma-related genes involved in the metabolic pathways, transcriptome sequencing of these two different apple varieties was conducted utilizing the Illumina platform. In total, 94 differentially expressed genes (DEGs) were found in the fatty acid metabolism, amino acid metabolism, the mevalonate pathway and phenylpropanoid pathway. Furthermore, compared to the Granny Smith apple, the expression of multiple genes and transcription factors were upregulated in the Jonagold apple, which might play important roles in the synthesis of aroma volatile compounds Our study contributes toward better understanding on the mol. mechanism of aroma synthesis in apples and provides a valuable reference for metabolic engineering and flavor improvement in the future.

Aroma investigation of new and standard apple varieties grown at two altitudes using gas chromatography-mass spectrometry combined with sensory analysis was written by Chitarrini, Giulia;Dordevic, Nikola;Guerra, Walter;Robatscher, Peter;Lozano, Lidia. And the article was included in Molecules in 2020.Safety of Octyl acetate The following contents are mentioned in the article:

The aromatic profile of apples constitutes important information for the characterization and description of local products. Apple flavor is determined by perception in mouth and aroma; while the first is mainly defined by sugars and organic acids, aroma is a complex mixture of many volatile organic compounds (VOCs) whose composition is often specific to the variety. Headspace-solid phase microextraction gas chromatog. coupled with mass spectrometry (HS-SPME-GC-MS) allows for the detection of detailed information of volatile constituents. In this study, eleven apple varieties (Braeburn, Fuji, Gala, Golden Delicious, Coop 39-Crimson Crisp, Dalinette-Choupette, Fujion, CIV323-Isaaq, Coop43-Juliet, SQ159-Natyra, UEB32642-Opal) grown in two pedoclimatic locations at different altitudes in South Tyrol (Italy) (ca. 225 m and ca. 650 m a.s.l.) were investigated. Thirty-eight VOCs were identified and combined with sensory anal. results (from 11 trained panelist) to characterize the aroma of new and standard apple varieties with a special focus on pedoclimatic location differences. The study shows strong diversification of the varieties based on their VOC profiles and sensory attributes, as expected. Moreover, investigating how the pedoclimatic location at different altitudes can influence the apple aroma profile, we identified twelve VOCs involved in these differences and provided a deeper investigation on how different altitudes can influence the apple aroma composition and perceptions combining the anal. and sensory parameters. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Safety of Octyl acetate).

Influence of citrus flavor addition in brewing process: characterization of the volatile and non-volatile profile to prevent frauds and adulterations was written by Trovato, Emanuela;Arigo, Adriana;Vento, Federica;Micalizzi, Giuseppe;Dugo, Paola;Mondello, Luigi. And the article was included in Separations in 2021.Category: esters-buliding-blocks The following contents are mentioned in the article:

In the last few years, the flavored beer market has increased significantly. In particular, consumers showed a growing interest in citrus-flavored beers. Citrus fruits contain, among other class of compounds, terpenes and terpenoids and oxygenated heterocyclic compounds The absence of a specific legislation concerning beer flavored production and ingredients reported on the labels makes these beers subject to possible adulterations. Solid phase micro extraction (SPME) followed by gas chromatog.-mass spectrometry (GC-MS) and gas chromatog.-flame ionization detector (GC-FID) anal. of the volatile profile together with the characterization of the oxygen heterocyclic compounds through high performance liquid chromatog. coupled to tandem mass spectrometry (HPLC-MS/MS) demonstrated to be a powerful anal. strategy for quality control. In this study, we combined the volatile and non-volatile profiles of ”citrus flavored mainstream beers”, in order to evaluate the authenticity and determine markers to prevent food frauds. The changes in the aroma composition of the unflavored types after the addition of peel, or citrus essential oil were also evaluated. The linear retention index (LRI) system was used for both techniques; in particular, its application in liquid chromatog. is still limited and represents a novelty. The coupling of the high sensitivity of the HPLC MS/MS method with the LRI system, it has made possible for the first time a reliable identification and an accurate quantification of furocoumarins in citrus-flavored beers.

Network Analysis of the Herb-Drug Interactions of Citrus Herbs Inspired by the “Grapefruit Juice Effect” was written by Lu, Jintao;Zhang, Dan;Zhang, Xiaomeng;Sa, Rina;Wang, Xiaofang;Wu, Huanzhang;Lin, Zhijian;Zhang, Bing. And the article was included in ACS Omega in 2022.Formula: C10H20O2 The following contents are mentioned in the article:

This study was performed to investigate the herb-drug interactions (HDIs) of citrus herbs (CHs), which was inspired by the “grapefruit (GF) juice effect”. Based on network anal., a total of 249 components in GF and 159 compounds in CHs exhibited great potential as active ingredients. Moreover, 360 GF-related genes, 422 CH-related genes, and 111 genes associated with drug transport and metabolism were collected, while 25 and 26 overlapping genes were identified. In compound-target networks, the degrees of naringenin, isopimpinellin, apigenin, sinensetin, and isoimperatorin were higher, and the results of protein-protein interaction indicated the hub role of UGT1A1 and CYP3A4. Conventional drugs such as erlotinib, nilotinib, tamoxifen, theophylline, venlafaxine, and verapamil were associated with GF and CHs via multiple drug transporters and drug-metabolizing enzymes. Remarkably, GF and CHs shared 48 potential active compounds, among which naringenin, tangeretin, nobiletin, and apigenin possessed more interactions with targets. Drug metabolism by cytochrome P 450 stood out in the mutual mechanism of GF and CHs. Mol. docking was utilized to elevate the protein-ligand binding potential of naringenin, tangeretin, nobiletin, and apigenin with UGT1A1 and CYP3A4. Furthermore, in vitro experiments demonstrated their regulating effect. Overall, this approach provided predictions on the HDIs of CHs, and they were tentatively verified through mol. docking and cell tests. Moreover, there is a demand for clin. and exptl. evidence to support the prediction. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Formula: C10H20O2).
