Investigating the differences of flavor profiles between two types of soy sauce by heat-treatment

The difference of flavor profiles and physicochemical properties between the two types of raw soy sauces and heated soy sauces were investigated in the present research. The results indicated that no significant changes of physicochemical properties, organic acids (except succinic acid) or CIELAB color space among the samples after heat-treatment were observed. However, the content of volatiles was increased by about 30.89% in the fortified sample (PP1) by heat-treatment. The contents of 26 and 15 constituents in PP1 and PP2 (natural fermented sample) were enhanced compared with their respective control (P1 and P2), respectively. According to the changes of the constituents with odor activity value (OAV), the contribution of heat-treatment on soy sauce flavor profiles was related closely to the raw soy sauce type. The spicy, caramel-like and fruity note of heated soy sauces were higher than that of raw soy sauces, and the increasements of spicy, caramel-like and fruity note of PP1 were higher than that of PP2. These results may contribute to optimizing the heat-treatment parameters and improve the flavor of soy sauce.

Characterization of Aroma Compounds in Two Meat Flavorings Prepared from Thermal Reaction of Enzymatic Hydrolysates of Black Pig and Common White Pig Meat Proteinss with Oxidized Lard

Meat flavorings were prepared by thermal reactions of enzymatic hydrolysates of black pig and common white pig (large white) meat proteins with oxidized lard. The volatile compounds of the two meat flavorings were analyzed by solvent assistant flavor distillation (SAFE) combined with gas chromatography and mass spectrometry (GC-MS). Based on retention indices and mass spectra, a total of 123 volatile compounds, including sulfur-containing compounds, nitrogencontaining heterocycles, oxygen-containing heterocycles, aldehydes, ketones, alcohols, acids, esters and hydrocarbons, were identified. In comparison, the white pig meat-derived flavoring had a greater percentage (relative to the total peak area) of alkyl furanes, aliphatic aldehydes and acids while the black pig meat-derived flavoring had a greater percentage of sulfur-containing compounds, nitrogen-containing heterocycles, and esters. However, their relative contents of ketones and alcohols were similar. Furthermore, by gas chromatography-olfactometry (GC-O), a total of 31 odor-active compounds were identified through comparison of their retention indices and odor characteristics with those of authentic standards. Among them, 28 compounds were common to two meat flavorings, and in particular dimethyltrisulfide, furfuryl mercaptan, 3-ethyl-2,5-dimethylpyrazine, 3-(methylthio) propanal,2-ethylthiophene,(E,E)-2,4-decadienal,(E)-2-decenal,(E)-2-nonenal,1-octen-3-ol and 3-hydroxy-2-butanone had high flavor dilution (FD) factors. However, the number of compounds with high FD values was greater in the black pig meat-derived flavoring than in the white pig meat-derived flavoring. Additionally, the spider-web plots for the potent odor-active compounds revealed that the black pig meat-derived flavoring had higher scores for meaty and fatty odors than the black pig meat-derived flavoring, which could explain why the black pig meat-derived flavoring had stronger meaty aroma than the black pig meat-derived flavoring.

Complete study of the pyrolysis and gasification of scrap tires in a pilot plant reactor

The pyrolysis and gasification of tires was investigated in a pilot plant reactor provided with a system for condensation of semivolatile matter. The study comprised experiments at 450, 750, and 1000C both in nitrogen and 10% oxygen atmospheres. In the gas phase, only methane and benzene yields increased with temperature until 1000C. In the liquids, the main components were styrene, limonene, and isoprene. The solid fraction (including soot) increased with temperature. Zinc content of the char decreased with increasing temperature. Analysis of the surface area of the solids showed that the area was similar in all cases to that of a commercial carbon black. The higher surface of the soot with respect to the chars was observed. The results coincided with published findings, i.e., kinetic severity function values would produce 0.2% of methane at 450C and 4.5% at 750-1000C.

Volatile composition and sensory and quality attributes of quince (Cydonia oblonga Mill.) fruits as affected by water stress

No information exists on the effect of water deficit on quince (Cydonia oblonga Mill.) fruit quality characteristics. In this paper, the effect of withholding irrigation water in the middle of the rapid fruit growth period on yield, main fruit physicochemical characteristics, sensory profile, and volatile composition of quince (cv. BA-29) was studied. The linear fruit growth phase was seen to be a critical phenological period for the marketable yield of quince because water deficit decreased the fruit weight, size, and moisture content. Also, this period was clearly critical for the fruit’s chemical characteristics. Water deficit induced important changes in an important number of the identified volatile compounds, characterized by decreases on pear, pineapple and apple sensory descriptors and increases on the green-herbaceous sensory descriptors. Moreover, total soluble solids increased and the total polyphenols content and antioxidant activity decreased as a result of water deficit effect, even though the still high levels of total polyphenols, regardless of the fruit water status, suggested that quinces can be used as an important source of natural antioxidants. The fruit sensory analysis indicated that the peel colour intensity of fruits from the water deficit treatment increased and fruit flesh texture improved. Indeed, the main handicaps for its consumption as fresh fruit (corkiness and fibreness) severely decreased and crunchiness increased.

Understanding the mechanism of [3 + 2] cycloaddition reaction of benzoisothiazole-2,2-dioxide-3-ylidene with nitrones

A theoretical investigation was carried out on the mechanism and regioselectivity of the [3 + 2] cycloaddition (32CA) reaction of benzoisothiazole-2,2-dioxide-3-ylidene with nitrone using Molecular Electron Density Theory through DFT calculations at B3LYP and wB97xD functionals with 6-31G(d,p) basis set in the gas phase and toluene. Hard and soft acids and bases principle, Parr functions, as well as potential energy surface analysis were utilized for studying the regio- and stereoselectivity of this reaction, and the obtained results are consistent with the experimental observations. The electron localization function analysis of the nitrone shows that there is a double bond between N and C in the absence of any carbenoid or pseudoradical center. Therefore, a zwitterionic structure for nitrone 2 can be suggested, expected that its 32CA reaction is zw-type. The noncovalent interactions topological analysis shows that the first sigma bond has been formed before reaching the TS, which is in line with a two-stage one-step mechanism.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. 272-16-2, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 272-16-2, in my other articles.
