FATTY ACID ESTERS AS A RENEWABLE BIOFUEL The continuously growing consumption of energy resources and the struggle for the ecological safety of the energy sector are forcing researchers all over the world to develop new energy sources. One of the key topics is looking for renewable fuels as alternative to the fossil fuels. Special attention is paid to alternative fuels for the transportation sector, since such fuels must correspond to a variety of physical, chemical and economic factors straight away. At the same time liquid hydrocarbon fuels remain to be the best solution for long-distance transportation due to its high energy density [1]. In this regard, internal combustion engines (ICE) will remain the main driving force of the transportation for a long time despite the rapid development of electric vehicles. [2], [3]. In such circumstances searching for the environmental friendly alternative fuels for ICE is an urgent task which is being solved in developed countries all over the world. Liquid biofuels based on fatty acid esters appeared to be one of the possible solutions to this problem. Such fuels are renewable, as they are

  • Effect of Enzymes on Strawberry Volatiles During Storage, at Different Ripeness
    Effect of Enzymes on Strawberry Volatiles During Storage, at Different Ripeness Level, in Different Cultivars and During Eating Thesis Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University By Gulsah Ozcan Graduate Program in Food Science and Technology The Ohio State University 2010 Thesis Committee: Sheryl Ann Barringer, Adviser W. James Harper John Litchfield 1 Copyright by Gülşah Özcan 2010 ii ABSTRACT Strawberry samples with enzyme activity and without enzyme activity (stannous chloride added) were measured for real time formation of lipoxygenase (LOX) derived aroma compounds after 5 min pureeing using selected ion flow tube mass spectrometry (SIFT-MS). The concentration of (Z)-3-hexenal and (E)-2-hexenal increased immediately after blending and gradually decreased over time while hexanal concentration increased for at least 5 min in ground strawberries. The formation of hexanal was slower than the formation of (Z)-3-hexenal and (E)-2-hexenal in the headspace of pureed strawberries. The concentration of LOX aldehydes and esters significantly increased during refrigerated storage. Damaging strawberries increased the concentration of LOX aldehydes but did not significantly affect the concentration of esters. The concentrations of many of the esters were strongly correlated to their corresponded acids and/or aldehydes. The concentration of LOX generated aldehydes decreased during ripening, while fruity esters increased. Different varieties had different aroma profiles and esters were the greatest percentage of the volatiles. The aroma release of some of the LOX derived aldehydes in the mouthspace in whole strawberries compared to chopped strawberries showed that these volatiles are formed in the mouth during chewing.

Received: 5 February 2020; Accepted: 3 March 2020; Published: 7 March 2020 Abstract: The metabolic activity in plants or fruits is associated with volatile organic compounds (VOCs), which can help identify the different diseases. P-ethylphenol has been demonstrated as one of the most important VOCs released by the Phytophthora cactorum (P. cactorum) infected strawberries. In this study, a bioelectronic nose based on a gas biosensor array and signal processing model was developed for the noninvasive diagnostics of the P.cactorum infected strawberries, which could overcome the limitations of the traditional spectral analysis methods. The gas biosensor array was fabricated using the single-wall carbon nanotubes (SWNTs) immobilized on the surface of field-effect transistor, and then non-covalently functionalized with different single-strand DNAs (ssDNA) through π–π interaction. The characteristics of ssDNA-SWNTs were investigated using scanning electron microscope, atomic force microscopy, Raman, UV spectroscopy, and electrical measurements, indicating that ssDNA-SWNTs revealed excellent stability and repeatability.

  • Oral Release Behavior of Wine Aroma Compounds by Using In-Mouth Headspace Sorptive Extraction (HSSE) Method
    foods Article Oral Release Behavior of Wine Aroma Compounds by Using In-Mouth Headspace Sorptive Extraction (HSSE) Method María Pérez-Jiménez, Carolina Muñoz-González and María Angeles Pozo-Bayón * Instituto de Investigación en Ciencias de la Alimentación (CIAL), CSIC-UAM, C/Nicolás Cabrera, 9, 28049 Madrid, Spain; [email protected] (M.P.-J.); [email protected] (C.M.-G.) * Correspondence: [email protected] Abstract: The oral release behavior of wine aroma compounds was determined by using an in-mouth headspace sorptive extraction (HSSE) procedure. For this, 32 volunteers rinsed their mouths with a red wine. Aroma release was monitored at three time points (immediately, 60 s, and 120 s) after wine expectoration. Twenty-two aroma compounds belonging to different chemical classes were identified in the mouth. Despite the large inter-individual differences, some interesting trends in oral release behavior were observed depending on the chemical family. In general, esters and linear alcohols showed rapid losses in the mouth over the three sampling times and therefore showed a low oral aroma persistence. On the contrary, terpenes, lactones, and C13 norisoprenoids showed lower variations in oral aroma release over time, thus showing a higher oral aroma persistence. Additionally, and despite their low polarity, furanic acids and guaiacol showed the highest oral aroma persistence. This work represents the first large study regarding in-mouth aroma release behavior after wine tasting, using real wines, and it confirmed that oral release behavior does not only Citation: Pérez-Jiménez, M.; depend on the physicochemical properties of aroma compounds but also on other features, such as Muñoz-González, C.; Pozo-Bayón, the molecular structure and probably, on the characteristics and composition of the oral environment.

Westbrook*, Guillaume Dayma, and Bin Yang An Experimental and Kinetic Modeling Study of Premixed Laminar Flames of Methyl Pentanoate and Methyl Hexanoate Abstract: Detailed chemical structures of stoichiometric and rich premixed lam- inar flames of methyl pentanoate and methyl hexanoate were investigated over a flat burner at 20 Torr and for methyl pentanoate at 1atm. Molecular beam mass spectrometry was used with tunable synchrotron vacuum ultraviolet (VUV) pho- toionization for low pressure flames of both methyl pentanoate and methyl hex- anoate, and soft electron-impact ionization was used for atmospheric pressure flames of methyl pentanoate. Mole fraction profiles of stable and intermediate species, as well as temperature profiles, were measured in the flames. A detailed chemical kinetic high temperature reaction mechanism for small alkyl ester oxi- dation was extended to include combustion of methyl pentanoate and methyl hex- anoate, and the resulting model was used to compare computed values with ex- perimentally measured values. Reaction pathways for both fuels were identified, with good agreement between measured and computed species profiles. Implica- tions of these results for future studies of larger alkyl ester fuels are discussed. Keywords: Spectroscopy, Reaction Kinetics.

Section 1: PCA analysis We provide a step by step example of how we conducted the PCA analysis. Assume we have 8 odors, each located on the vertexes of a 3 dimensional unit cube. Each odor can thus be represented by the exact binary code of the numbers 0 to 7. We can represent these odors in the following binary code matrix: Odor ID Pattern code: 1 0 0 0 2 0 0 1 3 0 1 0 4 0 1 1 5 1 0 0 6 1 0 1 7 1 1 0 8 1 1 1 1 Haddad Supp pp 2 Using any available mathematical tool (we used Matlab 'princomp' method) we can calculate the principle components scores of this matrix. In this case the values of the PC1 scores are: [1 0 0]. The PC1 projection value of each row is the projection of each row by the PC1 weight vector. For example the PC1 value of the first row is [0,0,0]X[1,0,0] = 0X1 + 0X0 + 0X0 = 0. (this is a vector multiplication). Thus the PC1 value of each row of this matrix is: 0,0,0,0,1,1,1,1. Note that usually the PC1 is calculated on a centered matrix (the columns of the matrix have zero mean) and thus the PC1 value might be shifted by some value.
