Ultrasonication is a nonthermal food processing method that is used in several applications (extraction, treatment before drying, freezing, inactivation of microorganisms, etc.) in ultrasound processing. The objective of this study is to investigate the effect of high power ultrasound and pasteurization on the aroma profile and sensory properties of apple juice and nectar. Samples were treated according to the exptl. design, with high power sonicator at ultrasound frequency of 20 kHz under various conditions (treatment time: 3, 6 and 9 min, sample temperature: 20, 40 and 60 °C, and amplitude: 60, 90 and 120 μm). The aromatic profiles of juices showed that, compared to the untreated samples of juices and nectars, ultrasonic treatment led to the formation of new compounds (which were not present in the untreated samples) or to the disappearance of compounds that were found in the untreated samples. Samples treated at the highest amplitude (120 μm) were used for evaluation and comparison with untreated and pasteurized samples using electronic tongue study. Principal component anal. confirmed the results of electronic tongue study, which showed that the ultrasound-treated and pasteurized juices had different scores compared to the untreated samples. This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7Product Details of 5444-75-7).

2-Ethylhexyl benzoate (cas: 5444-75-7) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. 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.Product Details of 5444-75-7

Esterification of Benzoic Acid with 2-Ethylhexanol in a Microwave Stirred-Tank Reactor was written by Pipus, G.;Plazl, I.;Koloini, T.. And the article was included in Industrial & Engineering Chemistry Research in 2002.Computed Properties of C15H22O2 The following contents are mentioned in the article:

A microwave applicator with a 2.45-GHz magnetron generator, which provides 460 W of output power, and waveguides to a stirred-tank reactor with a full volume of 500 mL was designed. The microwave reactor operates at high pressure and high temperature Esterification of benzoic acid with 2-ethylhexanol was chosen as the model reaction. The esterification was homogeneously catalyzed with sulfuric acid and para-toluene sulfonic acid. As heterogeneous catalysts, Cs_2.5H_0.5PW₁₂O₄₀, sulfated ZrO₂, Fe₂(SO₄)₃, and montmorillonite KSF were used. For the same operating conditions, the rate of esterification was concluded to be the same in both the microwave reactor and conventional exptl. setups. The results show that homogeneous catalysts are more effective than heterogeneous catalysts. Fe₂(SO₄)₃ was the most effective catalyst among the solid catalysts tested. The conversions in the microwave stirred-tank reactor were in agreement with the conversions predicted on the basis of the kinetic parameters obtained under conventional heating. High-pressure and high-temperature operating conditions allowed the reaction rate of esterification to be greatly increased. This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7Computed Properties of C15H22O2).

2-Ethylhexyl benzoate (cas: 5444-75-7) 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. 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.

Characteristics of particulate matter emissions from toy cars with electric motors was written by Wang, Xiaofei;Williams, Brent J.;Biswas, Pratim. And the article was included in Journal of the Air & Waste Management Association in 2015.Related Products of 5444-75-7 The following contents are mentioned in the article:

Aerosol emissions from toy cars with elec. motors were characterized. Particle emission rates from the toy cars, as high as 7.47 × 10⁷ particles/s, were measured. This emission rate is lower than other indoor sources such as smoking and cooking. The particles emitted from toy cars are generated from spark discharges inside the elec. motors that power the toy cars. Size distribution measurements indicated that most particles were below 100 nm in diameter Copper was the dominant inorganic species in these particles. By deploying aerosol mass spectrometers, high concentrations of particulate organic matter were also detected and characterized in detail. Several organic compounds were identified using a thermal desorption aerosol gas chromatog. The mass size distribution of particulate organic matter was bimodal. The formation mechanism of particulate organic matter from toy cars was elucidated. Implications: A possible new source of indoor air pollution, particles from elec. motors in toy cars, was identified. This study characterized aerosol emissions from toy cars in detail. Most of these particles have a diameter less than 100 nm. Copper and some organics are the major components of these particles. Conditions that minimize these emissions were determined This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7Related Products of 5444-75-7).

And the article was included in Energy & Fuels in 2013.Recommanded Product: 5444-75-7 The following contents are mentioned in the article:

Geting bituminous coal (GBC) was sequentially extracted with petroleum ether, carbon disulfide (CDS), methanol, acetone, and isometric CDS/acetone mixed solvent at room temperature to afford extracts 1-5 (E₁-E₅) and residue. Detailed characterizations of the extracts were performed with a gas chromatog./mass spectrometer (GC/MS), FTIR spectrometer, and direct anal. in real-time ionization source (DARTIS) coupled to an ion-trap mass spectrometer (ITMS). GBC and its residue were also analyzed with the FTIR spectrometer. Particle sizes of the residue were significantly reduced compared to those of GBC according to the observation with a scanning electron microscope. Arenes with 1-4 rings and more condensed arenes were enriched into E₁ and E₂, resp., while more heteroatom-containing organic species were detected in other extracts, especially in E₃ and E₄ according to GC/MS anal. The extracts, especially E₁-E₄, contain more aliphatic moieties and less aromatic moieties compared to GBC and its residue based on FTIR anal. DARTIS/ITMS proved to be a powerful tool for analyzing thermally labile and/or nonvolatile species, which are difficult to be identified with GC/MS, in the extracts This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7Recommanded Product: 5444-75-7).

2-Ethylhexyl benzoate (cas: 5444-75-7) 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. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Recommanded Product: 5444-75-7

BACKGROUND : Marinating is a Chinese traditional meat-processing method using aged brine that brings popular flavor together with food safety issues. In this study a novel method named quant. marinating (QM) was developed to improve Chinese traditional marinating (TM). Flavor compounds and sensory profiles of two marinated products were determined to verify if the improved marinating method could maintain the characteristic flavors of TM. RESULTS : Fifty-four, 60, 60, 60 and 44 volatile flavor compounds were identified from four processing stages of QM and TM resp. Contents of taste compounds first increased and then decreased in the processing stages of QM. The total free amino acid contents of QM and TM products were 789 and 536 mg per 100 g resp. The total nucleotide content of QM product (22.21 mg per 100 g) was higher than that of TM (20.75 mg per 100 g), while the fatty acid content of QM product (26.66 mg g^-1) was lower than that of TM (44.43 mg g^-1). Finally, QM received higher sensory scores than TM. CONCLUSION : Volatile flavor compounds, taste compounds and sensory properties of QM were richer than those of TM, indicating that QM can not only maintain the original aroma of TM but also have advantages in taste compounds © 2015 Society of Chem.

High-pressure 2D NOESY study of liquid 2-ethylhexyl benzoate was written by Adamy, S. T.;Kerrick, S. T.;Jonas, J.. And the article was included in Zeitschrift fuer Physikalische Chemie in 1994.Recommanded Product: 5444-75-7 The following contents are mentioned in the article:

A two-dimensional nuclear Overhauser effect spectroscopy (NOESY) study of the complex fluid 2-ethylhexyl benzoate (EHB) was performed at -20°C and 0°C up to pressures of 3000 bar. The high-pressure/low-temperature capability of the NMR set-up allowed the experiments to be done under conditions of very slow mol. motion where proton homonuclear cross relaxation rates were large in magnitude and NOESY cross peaks were significantly intense and fast-growing. Intramol. cross relaxation rates were determined by measuring cross peak build-up rates as a function of isotopic dilution of EHB in perdeuterated EHB (EHB-d₂₂) and extrapolating to infinite dilution A direct correlation between the rate of cross relaxation and viscosity/temperature was found and was explained in terms of the Debye expression. Insight into the time scales involved in mol. reorientation was also gained by calculation of correlation times. Internuclear cross relaxation rates were similarly investigated and related to the inverse of the rate of translational diffusion through Torrey’s translational model for relaxation. Finally, internuclear distances calculated from intramol. cross relaxation rates were used in conjunction with a mol. mechanics program to grain qual. information about possible EHB conformations.

Abstract: The present study aimed to evaluate the combined effects of betel leaf (Piper betle) extracts on sardine (Sardinella albella) muscle to extend its shelf life during storage in ice. Addnl., the effects of betel leaf extracts on microbial activity, biochem., sensory score, and biogenic amines formation were monitored in S. albella stored with traditional ice and ice with betel leaf extract during a 14-day storage period. Identification of bioactive compounds from P. betle revealed the presence of potent biopreservative compounds such as 4-methoxy-isophthalic acid, phenol, and propanoic acid. The effect of blended P. betle at two different concentrations (0.05% and 0.1% /L of distilled water) in the ice medium was tested for the protection of sardine meat and compared with preservation in traditional ice. Inhibitory effects (p < 0.05) on the microbial proliferation and biochem. markers of fish deterioration were evidenced for ice containing both concentrations of P. betle after 10-14 days compared with the control. The sensory score acceptability limit was reached at 10 days for sardines stored in traditional ice and 14 days for sardines stored in ice containing P. betle extract This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7COA of Formula: C15H22O2).

2-Ethylhexyl benzoate (cas: 5444-75-7) 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. 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.COA of Formula: C15H22O2

Effect of Ionic Liquid Treatment on Pyrolysis Products from Bamboo was written by Muhammad, Nawshad;Omar, Wissam N.;Man, Zakaria;Bustam, Mohamad Azmi;Rafiq, Sikander;Uemura, Yoshimitsu. And the article was included in Industrial & Engineering Chemistry Research in 2012.SDS of cas: 5444-75-7 The following contents are mentioned in the article:

In the present work 1-butyl-3-methylimidazolium chloride (BmimCl) and 1-butyl-3-methylimidazolium acetate (BmimOAc) ionic liquids were used for the dissolution of bamboo biomass. After dissolution the treated samples were precipitated by using H₂O. The calorific value, CHNS content, lignin content, and proximate anal. of the untreated and precipitated material were measured. The BmimCl-treated sample has a higher value for calorific value, elemental percentage of C, and lignin content as well as fixed C, compared to the untreated and BmimOAc treated samples. The untreated and ionic liquid treated samples were also characterized by TGA and XRD. Low thermal stability and change in crystalline form from cellulose Type I to Type II have been observed by the dissolution and precipitation treatment. Pyrolysis-gas chromatog./mass spectrometry (Py-GC/MS) was employed to achieve fast pyrolysis of the untreated and ionic liquid treated samples of bamboo. The desirable products with respect to bio-oil, such as phenols, furans, alcs., hydrocarbons, and aromatics are increased, while the undesirable products such as aldehydes and ketones, except for total acids, are decreased for the BmimCl treated sample.
