Krishnamoorthi, M. published the artcileExperimental, numerical and exergy analyses of a dual fuel combustion engine fuelled with syngas and biodiesel/diesel blends, HPLC of Formula: 929-77-1, the main research area is syngas biodiesel diesel combustion engine exergy simulation modeling.

This work investigates the effects of addition of syngas and biodiesel on a reactivity controlled compression ignition (RCCI) engine fuelled with diesel. SEM (SEM) of exhaust particulate matter has been done to obtain particulate matter (PM) morphol. Energy and exergy analyses have been performed to observe energy and availability shares, and to provide directions for the energy recovery systems. Closed cycle combustion simulations have been performed to complement the exptl. results and for an improved understanding of in-cylinder dynamics. Based on the initial study, used cooking oil based biodiesel blend (B20, 20% biodiesel) has been chosen in experiments The optimal operating conditions for syngas/diesel and syngas/B20 in RCCI mode for different operating parameters have been investigated. Injection pressure, injection timing and pre-injection mass ratio have been modified to get improved combustion efficiency at mid-load. Syngas/diesel mode with an injection timing of 19° before top dead center (bTDC) shows slightly higher brake thermal efficiency (BTE) with 22% and 77% lower oxides of nitrogen (NOx) and PM resp. as compared to conventional diesel combustion. In syngas/B20 mode, a maximum BTE of 24% has been observed for the case with a pre-injection at 50° bTDC with 30% mass fraction and 18° bTDC main injection timing. Syngas/diesel shows a reduction in primary soot particle count by about 67% and contains larger aggregates as compared to neat diesel.

Karthickeyan, V. published the artcileExperimental investigation on combined effect of ignition promoters and ceramic coating fuelled with papaya seed oil methyl ester in DI diesel engine, Computed Properties of 929-77-1, the main research area is papaya seed oil methyl ester DI diesel engine effect.

The present work offered a comprehensive investigation of engine characteristics of diesel engine driven with diesel and papaya seed oil Me ester (POME). The chem. compositions of POME were explored using FTIR and GC-MS anal. 1% of Di-tert-Bu Peroxide (DTBP) and Pyrogallol (PY) were used as ignition promoters with POME for achieving improved cetane number and enhanced ignition. In order to utilize the maximum available energy in the fuel thermal barrier coating was attempted. Partially Stabilized Zirconia coating on combustion chamber components leads to diminished heat loss from engine. The aim of the present experimentation was to analyze the consequence of papaya seed oil biodiesel with presence of ignition promoter in coated and uncoated engine characteristics. In PSZ coated engine, POME and PY blend showed 3.15% of increased thermal efficiency with 2.17% of declined fuel consumption. Reduced emissions were noticed with POME and PY blend in PSZ coated engine. Superior combustion efficiency, in-cylinder pressure, heat release rate and combustion duration were witnessed with POME and PY blend in coated engine due to short ignition delay. The practice of using ignition promoter-treated biodiesel in thermally coated engine was said to be the prominent method for achieving enhanced engine characteristics.

Jarukas, Laurynas published the artcileOptimization and validation of the GC/FID method for the quantification of fatty acids in bee products, SDS of cas: 929-77-1, the main research area is fatty acid bee product GC flame ionization detection quantification.

To the best of our knowledge, so far, no study has been conducted about the comparison of the total fatty acid concentration in the four bee products (honey, bee pollen, bee bread, and propolis) collected from Lithuania. Therefore, we aimed to optimize the derivatization parameters and to investigate a simple and sensitive gas chromatog.-flame ionization detection (GC-FID) method to determine fatty acids. The optimal derivatization parameters were used to analyze fatty acids in the bee products. Regarding sample preparation, three derivatization parameters were compared (temperature and extraction time with BF3/MeOH reagent) in order to obtain a high amount of the total fatty acids of interest from the fatty acid Me ester (FAME) standard The results showed that the highest total yield of fatty acids was conducted by using the conventional heating process at 70°C for 90 min. Under optimal conditions, there was obtained excellent linearity for fatty acids with determination coefficients of r2 > 0.9998. The LODs and LOQs ranged from 0.21 to 0.54μg/mL and 0.63 to 1.63μg/mL, resp. This method has been successfully applied to the qual. anal. of fatty acids in bee products. The above findings might provide a scientific basis for evaluating the nutritional values of bee products.

Mezo, Emerencia published the artcileThe role of ionic liquid interaction in the separation of fatty acid methyl esters-polyunsaturated geometric isomers in GC-MS, COA of Formula: C23H46O2, the main research area is fatty acid methyl ester ionic liquid chromatog column interaction.

Knowledge of the type and level of saturated and unsaturated fatty acids in food and clin. matrixes is of practical importance, but the wide variety of fatty acids makes analyses very complex. The discrimination of the geometric isomers of fatty acid needs proper and effective separation conditions. The efficiency of three different stationary phases was evaluated by GC-MS methods in the separation of fatty acids in their Me ester forms. Significant differences were observed in the efficiencies of polysiloxane-based (non-polar HP-5MS and medium/high polarity DB-225MS) and ionic liquid-based (SLB-IL111) columns. Baseline separation of the geometric isomers of linoleic acid Me ester was obtained by the extremely polar SLB-IL111 column, showing a preference over the other two columns. The optimization of the exptl. conditions (response linearity, limit of detection, limit of quantification, system suitability, intraday and interday repeatability and accuracy) showed the separation power of the ionic liquid interaction in the analyses by using short (25-30 m long) columns. By deducting the general principles of the interaction, predictions can be made for the separation of other isomers. The results facilitate the precise identification of various types of fatty acids in real samples for nutritional information.

Kuppusamy, Saranya published the artcileExamining the polyphenol content, antioxidant activity and fatty acid composition of twenty-one different wastes of fruits, vegetables, oilseeds and beverages, Recommanded Product: Methyl docosanoate, the main research area is fruit vegetable oilseed beverage polyphenol food waste antioxidant activity.

Abstract: One of the most abundantly available, cost-effective valuable resources that are of all-time concern for minimization and economical re-utilization is food waste, and quantifying the phenolic compounds and identifying the principle chem. constituents will favor their industrial exploitation potential. Water, methanol and ethanol extracts of 21 common food wastes of four different classes (fruits, vegetables, oilseeds and beverages) were screened by determination of their antioxidant activity (measured by DPPH activity, reducing power and phosphomolybdenum method) as well as total phenol, flavonoid and ascorbic acid contents. Further predominant chem. constituents (essential fatty acid composition and elemental contents) of the top four phytochem.-rich food wastes were investigated by GC-MS and ICP-MS. Water was more efficient for polyphenol extraction, and ethanol extracts for antioxidant power. Onion peel, pineapple skin and date seed had the highest phenolic content and antioxidant activity. Radish peel showed the highest ascorbic acid content (48.9 ± 1.5 mg/g). Onion peel emerged as a unique source of flavonoids (> 80%). Onion peel, radish peel and pineapple skin were identified to be the sources of essential fatty acid, i.e., linoleic acid, particularly radish peel being the rich source of alpha-linoleic acid highlighting its potential for human dietary intake or as animal feed. Moreover, the screened polyphenol and unsaturated omega fatty acid-rich food wastes constituted considerable quantities of essential macro- and micronutrients. Our study demonstrates the possibility of recovering large amounts of natural phytochems. from food wastes as alternatives to synthetics and for industrial applications.

Heidari, Mahsa published the artcileDiscrimination between vegetable oil and animal fat by a metabolomics approach using gas chromatography-mass spectrometry combined with chemometrics, Safety of Methyl docosanoate, the main research area is vegetable oil fat gas chromatog mass spectrometry chemometrics metabolomics; Adulteration; Fatty acid methyl ester; Gas chromatography–mass spectrometry; Lard; Olive oil; Principal component analysis.

Adulteration of olive oil with the other cheap oils and fats plays an important role in economics and has nutritional benefits. In this work, metabolite profiling was performed using gas chromatog.-mass spectrometry to identify and quantify animal fat (lard) adulteration in vegetable oil (olive oil). Principal component anal. could correctly identify and clustering olive oil, sunflower oil, sesame oil, lard, and adulterated samples through the changes in their fatty acid Me esters (FAMEs) profile. A targeted metabolomics method was then optimized and validated through construction of calibration curves of known FAMSs in olive oil and lard. The method was presented high linearity (R2 > 0.96) and good intra and inter day accuracy and precision (79-101 and 86-102% and 2-7 and 3-7, resp.) for determination of FAMEs. Afterwards the absolute concentration and relative percentage of FAMEs were successfully determined in 12 com. olive oils and 3 lards samples. Me myristate, Me palmitate, Me oleate, and Me stearate were selected as discriminant markers to identify and quantify lard adulteration even at a low level of lard (5%weight/weight), with errors less than 2% in the comparison of the absolute or relative concentrations of FAMEs using several statistical methods. The proposed methodol. allowed us to quantify the FAMEs simultaneously and also could predict small amount of lard in the adulterated olive oil samples.
