Hong, Kai published the artcileVarietal differences in the phytochemical components’ accumulation and aroma profile of three Humulus lupulus cultivars, Formula: C9H10O4, the publication is Food Control (2022), 108499, database is CAplus.

Humulus lupulus (hop) cone is a key ingredient in beer, which determines its taste and aroma. The impact of ripening on the bitter acids, aroma compounds, and polyphenols of hops has been reported sep., there is no systematic study on all three components. Here, three hop varieties in China were sampled to investigate the correlation between the harvest maturity and these three components, which indicated that polyphenols synthesized earlier than hop bitter acids, followed by the aroma compounds Variety differences of the hop cultivars prompted the obvious separation in the partial least-squares discriminant anal. (PLS-DA). Among three hop cultivars. TP1 with the highest contents of aroma compounds contributed to flower aroma, and with higher contents of bitter acids which contributed to bitter taste. In contrast, TP2 has been reported to be rich in caffeic acid, salicylic acid, syringaldehyde, (+)-catechin, and (-)-epicatechin. To analyze the hop aroma characteristics, two matrixes of hop tea and late-hopped beer were prepared and used for sensory evaluation. Compared to TP2 and QTF, the hop tea with TP1 scored best for strong (P < 0.01), herbal (P < 0.05) and citrus (P < 0.01). While the ‘strong’ and ‘herbal’ characteristics from terpene compounds receded in the late-hopped beer, the ‘citrus’ and ‘fruity’ notes from terpenol compounds remained noticeable.

Al Qahtani, Hayfa W. S. published the artcileChemical Profile, Antioxidant and Enzyme Inhibition Activities of Natural Saudi Sidr and Talh Honeys, HPLC of Formula: 134-96-3, the publication is Chemistry & Biodiversity (2022), 19(7), e202200227, database is CAplus and MEDLINE.

Honey is used since ancient time as a food and to cure many diseases. The present study investigated the chem. constituents, antioxidant and enzyme inhibition activities of natural Saudi Sidr (SH) and Talh (TH) honeys. Beside entire honey samples, Et acetate, ethanol and water extracts were prepared The total polyphenolic content of SH, TH and their extracts was in the range of 2.86-7.21 and 3.80-17.33 mg gallic acid equivalent/g, resp. and the total flavonoids content was in the range of 0.05-1.17 and 0.18-2.38 mg rutin equivalent/g, resp. Out of the 53 standards analyzed by HPLC, 27 compounds were detected with highest number of compounds identified in the Et acetate extract of TH (45%, 24/53) and SH (26%, 14/53), resp. Quinic acid was dominant compound identified in all honey samples with the highest content determined in TH ethanol extract (4454μg/g). The majority of tested samples possessed considerable anti-radicals and reducing ions capacity with the Et acetate extract from TH exerted significantly (p<0.05) the highest activity. All honey samples did not show chelating iron metal property. Honey samples revealed variable enzyme inhibition activity with TH (entire and/or Et acetate extract) showed significantly (p<0.05) the highest acetylcholinesterase, butyrylcholinesterase, tyrosinase and α-amylase inhibition activity. In conclusion, Et acetate is the best solvent for extraction of bioactive mols. from the two honey types. Moreover, the dark-colored TH contained the highest number of mols. and consequently exerted the best antioxidant and enzyme inhibition activities in most assays.

Yang, Yue-Qin published the artcileNitrogen-doped carbon anchored ruthenium nanoparticles for biofuel upgrade, Safety of 4-Hydroxy-3,5-dimethoxybenzaldehyde, the publication is Fuel (2022), 123100, database is CAplus.

The development of efficient catalysts is of great significance for the hydrodeoxygenation (HDO) of renewable biomass into value-added biofuel and chems. to mitigate the environmental and energy menace. Herein, we report a sustainable strategy to fabricate ruthenium nanoparticles (NPs) anchored on defective nitrogen-doped carbon (Ru@NC) via a facile pyrolysis of a mixture of ruthenium trichloride and urea with carbon support. The highly distributed Ru NPs, constituted by N-enriched graphene shells, have been established as an excellent catalyst for the selective HDO of lignin- and furan- derivatives toward biofuel upgrade. Impressively, Ru@NC exhibits enhanced catalytic performance to com. Ru/C, which could be attributed to the presence of the ensemble effects resulting from defective graphene sheet coverage on the Ru surface. Notably, the prepared catalyst was not affected after five successive reaction cycles, demonstrating superior stability and reproducibility. We envision that this work may pave the way for the development of highly efficient novel metal catalysts for heterogeneous catalytic HDO reactions in sustainable energy conversion.

Lou, Qian published the artcileDegradation of sulfonamides in aquaculture wastewater by laccase-syringaldehyde mediator system: Response surface optimization, degradation kinetics, and degradation pathway, Safety of 4-Hydroxy-3,5-dimethoxybenzaldehyde, the publication is Journal of Hazardous Materials (2022), 128647, database is CAplus and MEDLINE.

As a new type of environmental pollutant, environmental antibiotic residues have attracted widespread attention, and the degradation and removal of antibiotics has become an engaging topic for scholars. In this paper, Novozym 51003 industrialized laccase and syringaldehyde were combined to degrade sulfonamides in aquaculture wastewater. Design Expert10 software was used for multiple regression anal., and a response surface regression model was established to obtain the optimal degradation parameters. In the actual application, the degradation system could maintain a stable performance within 9 h, and timely supplement of the mediator could achieve a better continuous degradation effect. Low concentrations of heavy metals and organic matter would not significantly affect the degradation performance of the laccase-mediator system, making the degradation system suitable for a wide range of water quality. Enzymic reaction kinetics demonstrated a strong affinity of sulfadiazine to the substrate. Ten degradation products were speculated using high-resolution mass spectrum based on the mass/charge ratios and the publication results. Four types of possible degradation pathways of sulfadiazine were deduced. This work provides a practical method for the degradation and removal of sulfonamide antibiotics in actual sewage.

Wu, Rui-Qing published the artcileExtracts from Cinnamomum cassia leaf residues display antioxidant and anti-inflammatory activities, Name: 4-Hydroxy-3,5-dimethoxybenzaldehyde, the publication is Journal of Food Processing and Preservation (2022), 46(4), e16454, database is CAplus.

In order to explore the potential utilization value of Cinnamomum cassia leaf residues (CcLRs), the extracts of CcLRs and their biol. activities were investigated in this study. The results showed that Et acetate (EA) fraction of CcLRs’ crude extract had the highest total phenolic content (361.53 ± 19.24 mg GAE/g extract) and total flavonoid content (652.48 ± 9.91 mg RE/g extract), and its antioxidant capacity was 1.2- to 1.4-fold higher than that of the crude extract and other fractions. The in vitro NO inhibition rate of the EA fraction was up to 92.25% at concentration of 200μg/mL. The in vivo study showed that the EA fraction significantly improved the total antioxidant capacity (T-AOC) in D-galactose-induced aging mice by enhancing the total superoxide dismutase (T-SOD) and glutathione peroxidase (GSH-Px) activities, as well as inhibited the inflammatory response by reducing the induced nitrogen monoxide synthase (iNOS) activity. Thus, the extract from CcLRs possesses excellent antioxidant and anti-inflammatory activities, and has potential as a new dietary supplement in the food industry.

Gao, Anjiang published the artcileVolatile-char interactions during biomass pyrolysis: Reactor design toward product control, Name: 4-Hydroxy-3,5-dimethoxybenzaldehyde, the publication is Renewable Energy (2022), 1-7, database is CAplus.

This paper proposes a novel reactor featuring controllable adjustment of volatile-char interactions to investigate the pyrolysis of poplar wood and corresponding products. Controllable adjustment of volatile-char interactions enables the selective production of pyrolysis products. The oxygen content in biochar nearly disappears with the reduction of volatile-char interactions and the pore structure of biochar is improved after the interactions being intensified. Moreover, as the interactions reduce, the bio-oil yield increases by 1.23 times, and the outputs of acetic acid and phenols in the bio-oil exhibit decreasing trends, while that of levoglucosan is improved by nearly 4.5 times. Furthermore, the average mol. weight of bio-oil decreases from 786 to 322 g/mol with the continuous intensification of volatile-char interactions. It concludes that the controllable adjustment of volatile-char interactions plays a vital role in regulating the distribution of pyrolysis products and is of great importance to the production of light oil.

Mu, Jianlou published the artcilePhenolics from sea buckthorn (Hippophae rhamnoides L.) modulate starch digestibility through physicochemical modifications brought about by starch – Phenolic molecular interactions, Category: ethers-buliding-blocks, the publication is LWT–Food Science and Technology (2022), 113682, database is CAplus.

The phenolics from sea buckthorn (SP) exert various physiol. functions. This study examined the interactions of SP on the digestive and physicochem. properties of rice (RS) and wheat starch (WS), as well as the stability of starch-phenolics during digestion. The predominant phenolics from SP were syringic acid (22.14%), gallic acid (15.23%), and catechin (11.45%). The addition of SP manipulated the rheol. of starch pastes and affected the rearrangement and multi-scale structures of starch gels. Fourier transform IR spectroscopy and X-ray diffraction revealed that SP interacted with starch mainly through non-covalent hydrogen bonds, leading to a loose starch gel structure. The content of rapidly digestible starch of RS and WS decreased by 5.66% and 7.75%; the predicted glycemic index of RS (91.65) and WS (89.34) decreased to 81.81 and 80.84, resp., when the addition level of SP reached 15%, due to the inhibition activity of SP against digestive enzymes, as well as the mol. reorganisation of starch. After the in vitro digestion, the bioaccessibility of SP in starch gels increased by a magnitude of 2.58-fold (RS) and 2.98-fold (WS). These results provide evidence of using SP as functional formulations in controlling gel-like foods structure behaviors and modulating the glycemic response of starchy foods.

Shu, Bin published the artcileNewly generated and increased bound phenolic in lychee pulp during heat-pump drying detected by UPLC – ESI-triple-TOF-MS / MS, Safety of 4-Hydroxy-3,5-dimethoxybenzaldehyde, the publication is Journal of the Science of Food and Agriculture (2022), 102(4), 1381-1390, database is CAplus and MEDLINE.

During the thermal processing of fruit, it has been observed for phenolic compounds to either degrade, polymerize, or transfer into macromols. In this study, the bound and free phenolic compound composition, content, and phenolic-related enzyme activity of lychee pulp were investigated to determine whether the free phenolic had converted to bound phenolic during heat-pump drying (HPD). It was found that after HPD, when compared with the fresh lychee pulp (control), the content of bound phenolics of dried lychee pulp had increased by 62.69%, whereas the content of free phenolics of dried lychee pulp decreased by 22.26%. It was also found that the antioxidant activity of bound phenolics had also increased after drying. With the use of high-performance liquid chromatog.-tandem mass spectrometry, it was identified that (+)-gallocatechin, protocatechuic aldehyde, isorhamnetin-3-O-rutoside, 3,4-dihydroxybenzeneacetic acid, and 4-hydroxybenzoic acid were newly generated during HPD, when compared with the control sample. After drying, the contents of gallic acid, catechin, 4-hydroxybenzoic acid, vanillin, syringic acid, and quercetin in bound phenolics had also increased, and polyphenol oxidase and peroxidase still showed enzyme activity, which could be related to the conversion of free phenolics to bound phenolics. Overall, during the thermal processing of lychee pulp, the free phenolics weres found to be converted into bound phenolics, new substances were generated, and antioxidant activity was increased. Hence, it was concluded that HPD improved the bound phenolics content of lychee pulp, thus providing theor. support for the lychee processing industry. 2021 Society of Chem. Industry.

Gao, Hailian published the artcileEnhanced oxidative depolymerization of lignin in cooperative imidazolium-based ionic liquid binary mixtures, Recommanded Product: 4-Hydroxy-3,5-dimethoxybenzaldehyde, the publication is Bioresource Technology (2022), 127333, database is CAplus and MEDLINE.

The aerobic oxidation of lignin model 2-phenoxyacetophenone (2-PAP) in cooperative ionic liquid mixtures (CoILs) with 1-ethyl-3-methylimidazolium acetate ([C₂C₁i.m.]OAc) and 1-benzyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([B_ZC₁i.m.]NTf₂) was investigated. Complete degradation of 2-PAP was achieved with [C₂C₁i.m.]OAc/[B_ZC₁i.m.]NTf₂ molar ratio (R_IL) of 1/1 and 1/2 at 100 °C for 2 h. The conversion and product yields from CoILs were higher than those in pure ILs, indicating the cooperative effects of [C₂C₁i.m.]OAc/[B_ZC₁i.m.]NTf₂ on cleaving aryl-ether bonds. [C₂C₁i.m.]OAc promoted the catalytic cleavage of aryl-ether bonds and solvation, and [B_ZC₁i.m.]NTf₂ induced the formation of alkyl radicals and enhanced the product selectivity. Accordingly, the highest conversion of alkali lignin (79.8%) was obtained with RIL of 5/1 at 100 °C for 2 h, and phenol monomers (306 mg/g) were selectively produced. The CoILs exhibited good catalytic capacities for oxidative depolymerization of lignin, which strongly depends on the changes in intermol. interactions and structural organization with varying RIL.
