Biofilm Polysaccharide Display Platform: A Natural, Renewable, and Biocompatible Material for Improved Lipase Performance was written by Dong, Hao;Zhang, Wenxue;Wang, Yibing;Liu, Dong;Wang, Ping. And the article was included in Journal of Agricultural and Food Chemistry in 2020.Application In Synthesis of Octyl acetate The following contents are mentioned in the article:

Most of the microorganisms can form biofilms, which makes biofilms an abundant bioresource to be exploited. Due to the limitations of the application of current immobilization methods for biofilms, we developed an immobilization method called the biofilm polysaccharide display (BPD) strategy while maintaining the native biofilm structure and catalytic microenvironment of Clostridium acetobutylicum B3. Lipase Lip181 showed significant improvements in stability after chem. immobilization. For example, immobilized Lip181 retained 74.23% of its original activity after incubation for 14 days, while free Lip181 was totally deactivated. In addition, immobilized Lip181 maintained high residual activity (pH 5.0-11.0), which showed improved resistance to pH changes. Notably, this method did not decrease but slightly increased the relative activity of Lip181 from 6.39 to 6.78 U/mg. Immobilized Lip181 was used to prepare cinnamyl acetate, and it showed a maximum yield of 85.09%. Overall, this biofilm immobilization method may promote the development of biocatalytic and biofilm materials. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Application In Synthesis of Octyl acetate).

Octyl acetate (cas: 112-14-1) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Application In Synthesis of Octyl acetate

And the article was included in European Food Research and Technology in 2021.Related Products of 112-14-1 The following contents are mentioned in the article:

To investigate the impacts of wort gravity on perceived aroma characteristic of Tsingtao beer, sensory-directed flavor approaches, including sensory quant. descriptive anal. (QDA), gas chromatog.-mass spectrometry (GC-MS), gas chromatog.-olfactometry (GC-O), and aroma recombination experiments were employed. The result of QDA revealed that the aroma intensities of Tsingtao beer varied with the wort gravity. GC-MS determined 50 volatile compounds in all from the four kinds of Tsingtao beer samples with different wort gravity. Concentrations of most compounds were pos. correlated with beer wort gravity. Then 39 aroma-active compounds in the four beer samples were identified by GC-O, and 33 of them were found exited in Y4 sample with the highest wort gravity. The aroma recombination experiments showed that aroma-active compounds with AI �1 (GC-O detected) could simulate the aroma profile, indicating these compounds were aroma perceived compounds There were 16, 17, 19 and 23 aroma perceived compounds in the four kinds of samples, resp., indicating Y4 had the most abundant aroma perceived compounds This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Related Products of 112-14-1).

Octyl acetate (cas: 112-14-1) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Related Products of 112-14-1

Impact of crossflow microfiltration on aroma and sensory profiles of a potential functional citrus-based food was written by Hammad, Imane;Dornier, Manuel;Lebrun, Marc;Maraval, Isabelle;Poucheret, Patrick;Dhuique-Mayer, Claudie. And the article was included in Journal of the Science of Food and Agriculture in 2022.Related Products of 112-14-1 The following contents are mentioned in the article:

Citrus juices can be cold-concentrated by crossflow microfiltration (CMF) in order to obtain functional foods enriched in carotenoids, flavonoids and pectins. The work aimed to characterize the organoleptic quality of this type of micronutrient-dense foods through their aroma profile and sensory anal. Two citrus concentrates with and without a diafiltration step were compared. Both citrus products were very different, linked to aroma compound, sugar and organic acid contents. Due to its sugar/acidity balance and its better aromatic profile responsible for the citrus-floral flavor, the concentrate without diafiltration was preferred by the sensory panel. Thanks to a simple transfer model, we showed that retention of volatiles clearly varied from one aroma compound to another. The terpene hydrocarbons were the most retained by the membrane during CMF, probably because they were strongly associated with insoluble solids by adsorption. Even though the process modified their organoleptic profiles, both citrus-based products were well rated and can be consumed directly as pleasant functional drinks. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Related Products of 112-14-1).

And the article was included in Applied Organometallic Chemistry in 2020.Related Products of 112-14-1 The following contents are mentioned in the article:

A new heterogeneous Bronsted solid acid catalyst was prepared by tandem post-functionalization of MIL-101(Cr) and utilized for acetic acid esterification and alcoholysis of epoxides under solvent-free conditions. First, MIL-101(Cr) was functionalized with pyrazine to achieve MIL-101(Cr)-Pyz. Afterwards, the nucleophilic reaction of MIL-101(Cr)-Pyz with 1,3-propane sultone and next acidification with diluted sulfuric acid gave MIL-101(Cr)-Pyz-RSO₃H Bronsted solid acid catalyst. Various characterization methods such as Fourier transformation IR (FT-IR) spectroscopy, X-ray diffraction (XRD), elemental anal. (CHNS), XPS, SEM (SEM), energy-dispersive X-ray (EDX) spectroscopy, thermal anal. (TGA/DTA), acid-base titration, and N₂ adsorption/desorption anal. were employed to fully characterize the prepared catalyst. The catalyst showed high activity compared to unmodified MIL-101(Cr) in both catalytic acetic acid esterification and alcoholysis of epoxides. It can also be readily isolated from the reaction mixture and reused three times without major decrease in its activity. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Related Products of 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. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
