Tomato juice contains volatile compounds that are originally detected in fruit, such as terpenes, and others that are originated during processing by lipoxygenase activity, carotenoid co-oxidation and Maillard reaction that can be activated during the thermal treatments. This paper reports the analysis of the volatile compounds of tomato juice sampled by solid phase microextraction (SPME) and the optimization of the blanching parameters in tomato juice, using the volatile compounds as markers. One hundred and ninety volatile compounds, including ketones, aldehydes, alcohols, esters, ethers, hydrocarbons, sulfur, nitrogen and oxygen compounds, phenols, oxygen-containing heterocyclic compounds, free acids and lactones, were identified or tentatively identified by the GC-MS technique. The thermal treatment mainly modifies saturated and unsaturated C6 alcohols and aldehydes, esters, ketones and carotenoid derivatives. The optimal conditions for the blanching, selected by response surface modelling (RSM), were 67C for 24 min and 86C for 3.5 min for the cold break and the hot break treatments, respectively.

BACKGROUND: The sensory and head-space profiles of Italian and Spanish commercial tomato sauces were investigated. The Flash Profiling method was used to evaluate sensory characteristics. Samples within each set were ranked according to selected descriptors. One hundred volatile compounds were identified by solid-phase microextraction-gas chomatography-mass spectrometry. RESULTS: For Italian samples, the sensory notes of basil/aromatic herbs, acid and cooked tomato were among those perceived most by the assessors, whereas, in Spanish samples, the sensory attributes of garlic/onion and onion/sweet pepper and, in Italian samples, cooked tomato were among those found most frequently. Data were elaborated using multivariate statistical approaches and interesting correlations were observed among the different sensory attributes and related volatile compounds. CONCLUSION: Spanish samples were characterized by the highest content of volatiles linked to the thermal treatment of tomatoes and to raw and sauteed garlic and onion, whereas the Italian samples were characterized by terpenic compounds typical of basil and volatile molecules derived from fresh tomato. These results confirm the influence of both formulation and production processes on the aromatic profile (sensory attributes and volatile compounds) of tomato products, which is probably related to the different eating habits and culinary traditions in Italy and Spain.

The study investigated the volatile compounds of sesame oil and the effects of microwave processing (0?8 min with 1-min intervals), mainly focusing on the integral flavor characteristics and individual aroma-active compounds. A total of 82 characteristic odors were identified using GC×GC-TOF/MS. Fifteen volatile compounds with the highest odor activity values (OAV > 100) were selected as the key odors contributing to the flavor profile of microwaved sesame oil, including 2-methyl-propanal (pungent, malt, green), 2-methyl-butanal (cocoa, almond), furaneol (caramel), 1-octen-3-one (mushroom), 4-methyl-3-penten-2-one (sweet), 1-nonanol (fat, citrus, green), 2-methyl-phenol (phenol), 2-methoxy-phenol (smoke, sweet), 2-methoxy-4-vinylphenol (clove, curry), 2,5-dimethyl-pyrazine (cocoa, roasted nut, roast beef), 2-furfurylthiol (coffee, roast), 2-thiophenemethanethiol (sulfur), methanethiol (gasoline, garlic), methional (cooked potato), and dimethyl trisulfide (fish, cabbage). The OAVs significantly increased with a longer microwave process. Meanwhile, PCA results based on E-nose and cluster analysis results based on GC×GC-TOF/MS were similar to distinguish flavor formation during the microwave process. Practical applications: Sesame oils were prepared by a microwave process. Aroma-active compounds with the highest OAVs in sesame oils were not clear. Identification of key aroma compounds of sesame oils could adopt a comprehensive assessment method in combination with E-nose and individual odors detection. Microwave pretreatment as a new processing technology for sesame oil extraction could reduce the time consumption and produce a unique fragrant flavor compared to the traditional roasting process.

The aim of this study was to develop an analytical system to study the tomato aroma profile. An artificial chewing device coupled to a PTR-MS was developed to mimic, as close as possible, the release of volatiles during chewing in the human mouth and the retronasal olfaction perception.VOC profiles of 9 tomato lines, selected based on flavor characteristics by a sensory panel, were acquired by both a PTR-MS system following artificial chewing and by SPME-GC-MS and compared to the quantitative descriptive analysis (QDA) measured by the trained sensory panel.Based on multivariate statistical analysis, data obtained by the PTR-MS system showed a better correlation to the outcome of the QDA than SPME-GC-MS, especially for the descriptive parameters “tomato fragrance” and “tomato flavor”.The great advantage of such an analytical system was the possibility to study the release kinetics of volatiles during eating and the possibility to consider volatile concentration similar to in vivo condition resulting to an improved characterization of the aroma profile.

Palladium-catalysed direct arylation of 4- or 2-bromobenzenesulfonic acid derivatives in the presence of a variety of heteroaromatics was found to proceed using 0.1-0.5 mol% palladium acetate as the catalyst. However, both the nature and position of the SO2R substituent on such bromobenzenes has an influence on the reaction rates and yields. The presence of SO2Et or SO2NEt2 at the C2 or C4 position of bromobenzene is tolerated. Good results were also obtained from bromobenzene substituted at C4 by SO2NHPh or SO2OPh. On the other hand, the reactions of bromobenzenes bearing either SO2N(Me)CH2Ph or SO 2OAr at C2 led in some cases to intramolecular reactions instead of the desired intermolecular couplings. Some reactions were performed in cyclopentyl methyl ether, which can be considered as a green solvent.

Investigating physicochemical, volatile and sensory parameters playing a positive or a negative role on tomato liking

This study aimed at providing further insights into the positive and negative drivers of tomato liking. For this purpose, 13 tomato cultivars representing different typologies were characterized for physicochemical parameters and aroma volatiles, and were assessed by a trained panel for sensory descriptors, and by Italian consumers for liking. The relationships among the different parameters and their effects on consumer liking were studied by Partial Least Squares (PLS) analysis. Among physicochemical traits and sensory descriptors, seeds, reducing sugars, firmness, thick epicarp, soluble solids, sour taste, total acidity, citrate, herbaceous aroma and brightness were found to be drivers of liking, whereas pulp thickness, humidity, fruit weight, diacetyl-like odor and mealiness showed an opposite influence. For the aroma volatiles, 2-isobutylthiazole played a key role on liking and its positive contribution seemed to be supported by (Z)-3-hexen-1-ol, but suppressed by 6-methyl-5-hepten-2-ol, especially when tomatoes had a poor volatile fraction. These results represent a contribution to the knowledge that could lead to more effective breeding strategies aimed at improving tomato sensory quality.

Corrosion inhibition of X65 steel in sulfuric acid by two food flavorants 2-isobutylthiazole and 1-(1,3-Thiazol-2-yl) ethanone as the green environmental corrosion inhibitors: Combination of experimental and theoretical researches

Food flavors of 2-isobutylthiazole (ITT) and 1-(1,3-Thiazol-2-yl)ethanone (TEO) for the corrosion inhibition of X65 steel in H2SO4 were studied by electrochemical methods, atomic force microscopy (AFM), scanning electron microscopy (SEM) and theoretical calculations. Electrochemical experiments show that ITT and TEO can effectively inhibit the corrosion of cathode and anode of X65 steel, and they are mixed-type corrosion inhibitors. Surface topography analysis (SEM and AFM) also visually demonstrate that ITT and TEO form an effective barrier film on the X65 steel surface to isolate the corrosive medium. Theoretical calculations profoundly explain the inhibition mechanism of ITT and TEO at the molecular level. In addition, the adsorption behavior of ITT and TEO on the surface of X65 steel is consistent with Langmuir isotherm adsorption. The results of experimental and theoretical studies have shown that the inhibition effect of TEO is better than ITT for X65 in 0.5 M H2SO4.

Effect of Aliphatic Aldehydes on Maillard Reaction between Cysteine and Xylose and Meaty Flavor Formation

The effect of aliphatic aldehydes on Maillard reaction and meaty flavor formation was investigated in cysteinexylose model systems. The Maillard reaction in the absence and presence of hexanal, (E)-2-heptenal, or (E,E)-2,4-decadienal, was carried out at 90?, pH 5.5 for 5 h. Changes in the concentrations of xylose, cysteine, initial reaction intermediates (2-threityl-4-carboxythiazolidine and Amadori rearrangement product of cysteine (Cys-Amadori)) with reaction time were determined by high performance liquid chromatography with evaporate light scattering detection (HPLC-ELSD). Also, changes in the pH and absorbance values at 294 and 420 nm of the reaction mixtures were monitored. Volatile flavor compounds in the 3 h reaction mixtures were compartaively analyzed by solid phase microextraction coupled with gas chromatography and mass spectrometry (SPME-GC-MS). As indicated by decreased concentrations of Cys-Amadori and 2-threityl-4-carboxythiazolidine in the presence of aliphatic aldehydes, all the three aldehydes showed inhibitory effects on the initial stage of the Maillard reaction, among which (E)-2-heptenal was the stongest inhibitor, followed by (E,E)-2,4-decadienal and hexanal. Additionally, hexanal also showed inhibitory effect on the intermediate and final stages of the Maillard reaction, as indicated by decreased absorbance at 294 and 420 nm. However, (E)-2-heptenal and (E,E)-2,4-decadienal accelerated both the intermediate and final stages, as indicated by increased absorbance values at 294 and 420 nm, with the latter being more effective than the former. On the other hand, the reaction systems in the presence of (E)-2-heptenal and (E,E)-2,4-decadienal produced a relatively greater amount of total volatile sulfur-containing compounds than the blank model system, and additionally produced some new alkyl chain sulfur-containing compounds and furane derivatives such as 2-hexylthiophene and 2-propylfuran as detected by GC-MS analysis, due to participation of the aldehydes in cysteine-xylose reaction and reaction of the aldehydes themselves in the buffered cysteine-xylose solution.

Detailed characterization of Phellodendron chinense Schneid and its application in the corrosion inhibition of carbon steel in acidic media

We present a combined experimental and theoretical study of the effective corrosion protection of carbon steel in 1 M HCl solution by Phellodendron chinense Schneid (PCS) bark extract. Fourier-transform infrared spectroscopy (FTIR) and liquid chromatography tandem multi-stage mass spectrometry (LC-MSn) were employed for the extract characterization. The properties of PCS as a corrosion inhibitor were evaluated by electrochemical and gravimetric experiments. Quantum chemical calculation was used to describe the electronic and adsorption properties of the identified and characterized compounds found in the extract while molecular dynamics simulation was employed to predict the equilibrium configurations and binding energies of the compounds on the steel surface. The electrochemical results revealed that PCS acted as a mixed-type corrosion inhibitor whose efficiency increased with the extract concentration but slightly decreased with increasing temperature. Quantum chemical parameters, such as the energy difference (DeltaE) and the number of transferred electrons (DeltaN), were used to predict the contribution of each characterized compound to the inhibition process while molecular dynamics simulation predicted parallel orientations for the configuration of the compounds and high binding energies on the metal substrate.
