Huangjiuis one of the oldest alcoholic beverages in the world. It is usually made by fermenting grains, and Qu is used as a saccharifying and fermenting agent. In this study, we identified differential carbonyl compounds inHuangjiuwith varying sugar contents from different regions. First, we developed and validated a detection method for volatile carbonyl compounds inHuangjiu, and for optimal extraction, 5 mL ofHuangjiuand 1.3 g/L of O-(2,3,4,5,6-pentafluorobenzyl)hydroxylamine hydrochloride (PFBHA) were incubated at 45 °C for 5 min before extracting the volatile carbonyl compounds at 45 °C for 35 min. Second, the targeted quantitative analysis of 50 carbonyl compounds inHuangjiushowed high levels of Strecker aldehydes and furans. Finally, orthogonal projections to latent structures discriminant analysis (OPLS-DA) was used to differentiate betweenHuangjiuwith different sugar contents, raw materials, and region of origin. A total of 19 differential carbonyl compounds (VIP > 1,p< 0.05) were found inHuangjiuwith different sugar contents (semidry and semisweetHuangjiu), and 20 differential carbonyl compounds (VIP > 1,p< 0.05) were found in different raw materials forHuangjiuproduction (rice and nonriceHuangjiu). A total of twenty-two and eight differential carbonyl compounds, with VIP > 1 andp< 0.05, were identified in semidry and semisweetHuangjiufrom different regions (Zhejiang, Jiangsu, Shanghai, and Fujian), respectively.Keywords:Huangjiu;carbonyl compounds;PFBHA;targeted metabolomics;OPLS-DA

This study investigated the effects of frying of foods on the fatty acids and formation of carbonyl compounds in frying soybean oils. Rice cakes and hairtails were selected as typical starch/protein-based foods for frying using soybean oil. In this study, fifteen carbonyl compounds were detected by an efficient high performance liquid chromatography (HPLC) developed by this paper. During frying with rice cakes or hairtails, the linolenic acid in frying oils was reduced by approximately 20 % compared with that in the no-food frying system. Fewer types of carbonyl compounds (frying without food: 11; frying of rice cakes: 9; frying of hairtails: 6) were detected, and the levels of some carbonyl compounds such as trans-2-nonenal were decreased. Results suggested that frying rice cakes or hairtails can substantially influence the contents of fatty acids and the formation of carbonyl compounds in frying oils. This study provides references for evaluating the quality of fried oil and food.

Carbon nanocages (CNCs) have attracted tremendous interest in heterogeneous catalysis due to their promising properties of porous structure and improved mass transfer. Nevertheless, the controlled synthesis of CNCs remains a great challenge. Herein, we have shown the successful construction of functionalized N-doped CNCs (NCNCs) via a one-stone-two-birds strategy. The selective use of hexacarbonyl molybdenum (Mo(CO)6) can not only protect the profile of the ZIF-8 precursor from collapse during thermal treatment but also be sacrificed for the functionalization of NCNCs after pyrolysis. Detailed mechanism studies reveal that Mo(CO)6 evolves into MoO3 on the surface of ZIF-8 and then facilitates the rapid pyrolysis of ZIF-8, leading to the formation of NCNCs decorated with small-sized MoC nanoparticles (MoC/NCNCs). The versatility of this one-stone-two-birds strategy has been validated by the generations of Cr- and W-decorated NCNCs. Moreover, MoC/NCNCs can serve as a selective and stable catalyst for furfural hydrogenation. This work provides a facile and universal strategy for fabricating and functionalizing CNCs, which attracts research interest in the fields of chemistry, material science, catalysis, and beyond.

α-dicarbonyl compounds (α-DCs) serve as potential biomarkers for oxidative stress-related diseases but are difficult to detect. To study the metabolism of carbonyl compounds , we developed a new mass spectrometry probe, 3-benzyl-2-oxo-4λ 3 -thiazolidine-4-carbohydrazide (BOTC), containing hydrazyl groups for the targeted detection of carbonyl functional groups. In a novel approach, we used BOTC pre-column derivatization with ultrahigh performance liquid chromatography–tandem mass spectrometry (UHPLC-MS/MS) to simultaneously detect four kinds of α-DCs in red wine as well as in urine after drinking. The α-DCs were completely separated (R 2 ≥ 0.9995), detection was sensitive (detection limit was 12.5–50 fmol), consistent (intraday and interday precision was 0.1–5.7 %), and efficient (average recoveries were 103.3–110.2 %). The method was applied to the analysis of α-DCs in different wines and the dynamic monitoring of transit and excretion in vivo after drinking. Our novel method provides a new strategy for the detection of α-dicarbonyl compounds in red wine and dicarbonyl compounds produced in oxidative stress-related diseases.

Benzimidazole and metal cobalt salts were employed in the synthesis of Co-ZIF-9 by solvothermal crystallization. Highly active catalysts for selective hydrogenation of carbonyl compounds were developed. The optimal nanocatalyst Co-ZIF-350 manifested remarkable activity and selectivity for the hydrogenation of cyclohexanone under mild conditions. Catalytic conversion of cyclohexanone reached the highest over the catalyst of Co-ZIF-9-pyrolyzed at 350 °C for 2 h, in which the conversion of cyclohexanone was 100 % and the selectivity of cyclohexanol was ＞99 % at 50 °C. A wide scope of ketones/aromatic aldehydes could be selectively reduced to the corresponding alcohols with high yields. Importantly, the nanocatalyst Co-ZIF-350 presented good tolerance of substrates with various functional groups under mild conditions.

Reductive amination of aldehydes/ketones with aqueous NH 3 and hydrogenation of nitriles to primary amines with Co catalysts were reported. Co@NC-700 exhibited remarkable activity and high selectivity for the reductive amination of aldehydes/ketones with aqueous NH 3 and the hydrogenation of nitriles to primary amines. Several primary amines can be obtained with good to excellent yields via the reductive amination of aldehydes/ketones and the hydrogenation of nitriles. The nitrogen-doped carbon(C)-supported Co@NC-700 metal catalyst was prepared via the pyrolysis of bioMOF Co/adenine in activated C. Co@NC-700 can be reused five times without evident loss of activity.

Formaldehyde is deemed to be an indispensable industrial product that has been widely applied in manufacture of resins, drugs, building materials, etc. It has been widely accepted that, nevertheless, residual formaldehyde will cause pathogen reactions, even leading to cancers like leukemia. Thus, a facile and efficient approach has been designed to achieve the determination of formaldehyde by ultraviolet and visible (UV–vis) spectrophotometry in liquid media. In detail, O-(carboxymethyl) hydroxylamine (C 2 H 5 NO 3 ·0.5HCl) is chosen as the detection reagent for the specific recognition of formaldehyde on account of its unique aminooxy (-O-NH 2 ) which can react with formaldehyde to form oxime bonds (O-N CH 2 ), accompanied with the only by-product of H 2 O. Likewise, this simple and sensitive detection approach based on the chemical detection reagent C 2 H 5 NO 3 ·0.5HCl can also be applied to the determination of other aldehyde homologs with carbonyl groups including acetaldehyde, acetone, benzaldehyde, 1, 4-phthalaldehyde. As a result, all the UV absorbances of analytes display remarkable linear detection relationships. The limits of detection (LOD) and limits of quantitation (LOQ) values are in the range of 0.03–1.16 ppm and 0.03–5.81 ppm respectively, with RSDs of 3.27–3.75 %, evidencing the feasibility of our method to determine formaldehyde and its homologs by UV–vis spectrophotometry and auspicious prospects of practical applications.

The use of non-noble metal catalysts with high activity is of great importance for organic transformations. Herein, nitrogen-doped carbon supported cobalt catalysts with high surface area up to 981.2 m 2 /g were prepared via the simple pyrolysis of cobalt coordinated organic polymers with silica as the hard template. The pyrolysis temperature showed a great effect on the structure and properties of the as-prepared catalysts. The Co@NC-800 catalyst with the pyrolysis temperature of 800 °C demonstrated a high activity for the selective reductive amination of carbonyl compounds to primary amines with ammonia and hydrogen. Structurally-diverse primary amines with yields in the range from 81.8% to 100% were attained under the optimal conditions. The Co@NC-800 catalyst could be reused without the loss of its activity. The Co@NC-800 catalyst demonstrated comparable activity as the reported heterogeneous noble metal catalysts.

This research was to investigate the protein deterioration (oxidation, glycation, hydrolytic cleavage, the Maillard reaction) of precooked fish during storage (0 ℃, 1 – 7 d) and reheating (75 ℃, 10 min) as affected by precooking treatments (90 °C, 8 – 25 min) similar to home cooking and commercial pasteurization. The amounts of trichloroacetic acid (TCA)-soluble peptides (3.68 ± 0.39 – 5.10 ± 0.87 μmol try/g) and fluorescence advanced glycation end-products (AGEs) (718.3 ± 56.3 – 870.1 ± 90.6 AU) in precooked fish continuously increased during storage while the corresponding tryptophan fluorescence (699.0 ± 41.8 – 882.4 ± 82.8 AU) decreased, implying the concurrence of hydrolytic cleavage, glycation and oxidation of proteins. More severe precooking treatments generally resulted in higher levels of TCA-soluble peptides and fluorescence AGEs, although the mild reheating applied had no significant effect on the amount of fluorescence AGEs. The levels of 3-deoxyglucosone, glyoxal, methylglyoxal, 2,3-pentanedione, and 2,3-butanedione in precooked or reheated fish had no obvious relationship ( r = 0.046 – 0.598) with each other, but their cluster analysis result was in agreement with their chemical natures and formation pathways. While 3-deoxyglucosone was the dominant α-dicarbonyl, accounting for an average of 69.8% of the sum of five α-dicarbonyls in precooked fish with or without being reheated, the mean level of 2,3-pentanedione was 3.3 times more than 2,3-butanedione, implying that this α-diketone should not be overlooked.

In this study, five salts containing the same anion fac-[FeII(CO)3I3]− were prepared through the reaction of cis-[Fe(CO)4I2] with organic amines whose protonated forms, i.e., (EtNH3+), (PrNH3+), (BuNH3+), (PentNH3+), and (Et2NH2+), become the cations of the salts 1, 2, 3, 4, and 5, respectively. These aminium salts, which are soluble in water and polar organic solvents such as DMSO and methanol, were characterized by various techniques including X-ray single-crystal diffraction. These salts underwent solvolysis in both water and DMSO to release CO, following first-order kinetics. In DMSO, the decomposition of these salts proceeded via a significantly simpler mechanism without the involvement of radicals than that in water, and the CO-release rate of these salts was almost linearly related to the hydrophobicity (the logarithm of the oil/water partition coefficient P) of the amines. The CO-release rate was substantially faster in water and in addition to undergoing solvolysis, the anions generated an iodine radical, I˙. Due to the complicated decomposition of these salts in water, the CO-release proceeded in a two-stage manner. The iodine radical was found to be at least partly responsible for the cytotoxicity of these salts in water; this indicates that the proposed anion has potential for applications in cancer therapy.

As a potential health hazard, α-dicarbonyl compounds have been detected in the thermally processed foods. In order to investigate the formation kinetics of α-dicarbonyl compounds, liquid chromatography-electrospray tandem mass spectrometry was employed to determine the content of α-dicarbonyl compounds in glucose-only and glucose-glutamic acid (glucose-Glu) thermal reaction models. The 3-deoxyglucosone content was significantly higher than 6 α-dicarbonyl compounds at 90–110℃, 0–6 hr in the two tested systems. The glutamic acid promoted the content accumulation of 1-deoxyglucosone, diacetyl, methylglyoxal, and glyoxal, whereas inhibited the content of 3-deoxyglucosone and 3,4-dideoxyglucosone. Three-fifths of the tested compounds content increased linearly with time increasing, but in glucose-only system, the 1-deoxyglucosone content increased logarithmically at 95–110℃ over reaction time. The formation of glucose (100–110℃, glucose-only and glucose-Glu), 5-hydroxymethylfurfural (100–110℃, glucose-only), 1-deoxyglucose (105–110℃, glucose-Glu), 3,4-dideoxyglucosone (110℃, glucose-Glu), glyoxal (95–110℃, glucose-Glu) and diacetyl (90–95℃, glucose-Glu) could be well fitted by exponential equation. Shortening the heating time and reducing heating temperature (except glyoxal in glucose-only system) were the effective methods to decrease α-dicarbonyl compounds content in the two tested systems. Additionally, high temperature could also reduce α-dicarbonyl compounds content, such as 3-deoxyglucosone (≥110℃, glucose-only), 1-deoxyglucosone (≥110℃, glucose-only), glucosone (≥110℃, glucose-only; ≥100℃, glucose-Glu), methyloxyl (≥110℃, glucose-only; ≥100℃, glucose-Glu), diacetyl (≥110℃, glucose-only), and glyoxal (≥100℃, glucose-Glu).
