摘要：
Metalloporphyrin and gold nanoparticles (AuNPs) were fixed on the surface of hollow zeolite imidazole framework-8 (HZIF-8) by cation exchange and cross-linking reaction. The obtained hybrid nanozyme, Au/HZIF-8@TCPP(Fe), was fully characterized by TEM, HRTEM, EDS element mapping and XPS. Then, its peroxidase-like activity was explored with Km of 1.74 mM and Vmax of 9.60 × 10-8 M·S-1 towards H2O2, indicating excellent catalytic activity. Based on cascade reaction between choline oxidase and Au/HZIF-8@TCPP(Fe), a quick colorimetric method was established for choline detection in infant formula milk powder. After comprehensive verification, this method presented the merits of simple operation, satisfied detection limit (0.05 mM), wide linear range (0.05–2.0 mM), high accuracy (recovery of 92.2%-105.2%) and nice selectivity. This colorimetric method was applied to the determination of choline in milk powders of five brands. Our study could offer valuable reference for finding highly efficient nanozyme and constructing novel optical biosensors. © 2022 Elsevier Ltd

摘要：
Selenium is an essential micronutrient and is well known for its role in regulating metabolism. However, it is also highly toxic in some of its forms and above certain concentration levels. Amorphous selenium nanoparticles (SeNPs) are extremely unstable and convert into non-bioactive or gray elemental selenium with crystal-type structures due to aggregation, which limits its antioxidant and anti-tumor activities. To overcome these limitations, monodisperse SeNPs were obtained by stabilizing SeNPs with glucan and rosmarinic acid (RA) via Se-O bonds and polysaccharide-polyphenol interactions. The prepared glucan-RA-SeNPs were found much more stable than both SeNPs and glucan-stabilized SeNPs. Meanwhile, glucan-RA-SeNPs displayed enhanced bioactivities including an improved free radical scavenging ability and an increased cytotoxicity toward cancer cells. The underlying mechanism might be related to caspase activation by glucan-RA-SeNPs, thus overproducing intracellular reactive oxygen species and eventually resulting in cancer cell apoptosis. Our work proposes a feasible strategy for improving the structure-bioactivity of SeNPs through polysaccharide-polyphenol interaction. © 2022 American Chemical Society. All rights reserved.

摘要：
The current non-chromatographic speciation methods generally involve the conversion of different species by oxidation/reduction reactions, which may cause inherent problems such as contamination risk, time consumption and complex operations. In this work, in-syringe solid phase extraction (IS-SPE) was combined with in-syringe vortex-assisted solidified floating organic drop microextraction (IS-VA-SFODME) for the detection of Sb(V) and Sb(III) in rice wines by graphite furnace atomic absorption spectrometry. Firstly, IS-SPE involved the use of ZnFe2O4 nanotubes as the sorbent for the isolation and enrichment of Sb(V) and removal of the matrix components such as ethanol, pigment, sugars and carbohydrates. Then, IS-VA-SFODME was used for enriching Sb(III) in the original sample solution after IS-SPE. This technique exhibited good anti-interference ability and high enrichment efficiency without tedious pre-oxidation/pre-reduction and centrifugation/filtration operations, which may cause the contamination of samples. Under the selected conditions, the detection limits were 4.5ngL−1 and 3.2ngL−1 for Sb(III) and Sb(V) with relative standard deviations of 7.3% and 5.1%, respectively. This procedure was used with satisfactory results for the detection of Sb(III) and Sb(V) in rice wine samples and a certified reference material of water sample. Recoveries of spiked experiments ranged from 91.0 to 107%. © 2022 Taylor & Francis Group, LLC.

摘要：
To examine the safety of Chinese traditional fermented fish products (CTFPs) available on the Chinese market, nitrite, nitrate, biogenic amines (BAs) and volatile N-nitrosamines (VNAs) content in 33 commercial CTFPs from different provinces was investigated. The mean content of nitrite and nitrate wase 0.63 and 749.5 mg/kg, respectively. Concerning the occurrence of BAs, the accumulation in all CTFPs samples remained at low levels, whereas only in one sample from Guangxi the histamine content exceeded the critical level (50 mg/kg). In addition, six types of VNAs, including N-nitrosodimethylamine (NDMA), N-nitrosoethylmethylamine, N-nitrosopiperidine, N-nitrosopyrrolidine, N-nitrosomorpholine and N-nitrosodiphenylamine, were detected in a high number of samples. The NDMA content in 36.4% of the samples and the total VNAs content in about 63.6% of the samples were unacceptable. Principal component analysis indicated that the accumulation of NDMA and total VNAs was closely related with the content of histamine, tyramine and nitrate. © 2021 Taylor & Francis Group, LLC.

摘要：
To answer which is the key component caused the alterations of gluten in the presence of persimmon tannin (PT), the changes on physical properties, morphology, subunits coposition and cross-linking types of glutenin and gliadin were investigated. The results showed that compared with gliadin, glutenin was more sensitive to PT due to the greater changes in the thermal stability, network structure and aggregation behavior. This might be explained by the remarkable decreases in soluble subunits content, free sulfhydryl groups (S[sbnd]H), disulfide bonds (S[sbnd]S) and free amino groups (–NH2) cross-linking of glutenin after 8% of PT addition, as well as the varying degree in subunits composition. Therefore, glutenin played a more important role in the changes in the properties and network structure of gluten induced by PT than gliadin. Our work provided a guidance for the incorporation of phenolic compounds in wheat flour-based products. © 2022 Elsevier Ltd

摘要：
There have been rare reports about the structure/composition of polymers in blueberry skin and their changes during fermentation for wine production. In this study, the compositional changes occurring in blueberry skin during fermentation were tracked by a combination of cell wall analysis techniques including infra-red spectroscopy, monosaccharide analysis, and comprehensive microarray polymer profiling (CoMPP). The cross-corroborating data revealed that blueberry skin cell wall is particularly rich in xyloglucan. Chemical fractionation analysis indicated that the KOH soluble fraction is a dominant fraction in fermented blueberry skin. Interestingly, the KOH soluble fraction contained abundant epitopes associated with pectin branch chains, indicating tight binding of some enzyme-resistant pectin polymers to hemicellulose. This study provides important implications for the development of effective strategies to extract beneficial substances (such as aromatics, tannins and pigments) from berry tissues during processing. © 2022 Elsevier Ltd

摘要：
As aromatic compounds found within red fruits and berries, raspberry ketones (RK) have the potential for nonalcoholic fatty liver disease (NAFLD) amelioration. However, the mechanism of RK on NAFLD is unclear, and their bioactive metabolite is unknown. As the major metabolites of RK that are mainly distributed in the liver, rhododendrol (RHO) is used in our current study to test whether RHO accounts for the beneficial effect of RK on NAFLD and the underlying mechanism. In a 16-week trial, RHO significantly decreased final body weight, improved serum lipid profile and ameliorated liver inflammation. Moreover, RHO changed the gut microbiota composition, including lean phenotype-related genera, such as Bacteroides, Bilophila, Oscillibacter, Lachnospiraceae_bacterium_28_4 and Bacteroides sartorii. Liver metabolomics analysis indicated that RHO enhanced the abundance of metabolites related to alanine, aspartate, and glutamate metabolism, as well as arginine and proline metabolism. Spearman correlation analysis revealed that these metabolites were positively correlated with the gut genera enriched by RHO. Here, our findings suggested that the metabolic effects of RK might be partially attributed to its metabolite-RHO, and mice supplemented with RHO have dramatically altered hepatic metabolisms concurrent with shifts in specific gut bacteria. © 2022 The Royal Society of Chemistry.

Gliadin;Grape skin anthocyanin extracts;Interaction;Molecular docking;Spectroscopy
摘要：
In order to broaden the application of grape skin anthocyanin extract (GSAE) in flour products, the interaction of gliadin (Gli) and GSAE were investigated. Seven anthocyanin components from GSAE were identified by HPLC-MS2, which could form complexes with Gli having different binding rates based on UV, FTIR and HPLC analysis. The fluorescence quenching experiment showed that GSAE was capable of efficiently quenching the intrinsic fluorescence of Gli through hydrophobic interactions, and the binding parameters were near to one unit at the given temperatures. Additionally, GSAE binding changed the conformational properties of Gli, increasing α-helix and β-turn content, but decreasing β-sheet and irregular coil content. The molecular docking suggested that Gli possessed various binding sites bound with different anthocyanin monomers, mainly depending on hydrogen bonds and hydrophobic interactions. These findings further proved the formation of Gli-GSAE complex, indicating the potential of anthocyanins as natural colorant. © 2022 Elsevier Ltd

摘要：
Polyglycerol-10 dialdehyde, prepared by NaIO4 oxidation of polyglycerol-10, was used as a novel cross-linking reagent for sodium caseinate (NaCas) modification, which can alter the emulsifying properties of proteins. The results revealed that cross-linking resulted in an approximately two-fold increase in the surface hydrophobicity and a 15° increase in the contact angle of NaCas. The emulsifying activity index, emulsion stability index, and oil-binding capacity of cross-linked NaCas also increased significantly. Furthermore, the stabilization of soybean oil-in-water emulsion demonstrated that cross-linked NaCas can prevent oil droplets from aggregating during storage; meanwhile, compared to the native protein, the cross-linked NaCas improved the stability of the emulsions under high ionic strength and temperatures. It is worth noting that the polyglycerol-integrated NaCas showed less adsorption on the glass surface. These findings clearly illustrate that renewable polyglycerol can be used as a novel cross-linking reagent for protein modification, which will provide proteins with promising features for use as emulsifiers in the food, pharmaceutical, and cosmetic industries. © 2022 Elsevier B.V.

anthocyanins;bioactivity;bioavailability;technological applications
摘要：
Over the years, anthocyanins have emerged as one of the most enthralling groups of natural phenolic compounds and more than 700 distinct structures have already been identified, illustrating the exceptional variety spread in nature. The interest raised around anthocyanins goes way beyond their visually appealing colors and their acknowledged structural and biological properties have fueled intensive research toward their application in different contexts. However, the high susceptibility of monoglycosylated anthocyanins to degradation under certain external conditions might compromise their application. In that regard, polyglycosylated anthocyanins (PGA) might offer an alternative to overcome this issue, owing to their peculiar structure and consequent less predisposition to degradation. The most recent scientific and technological findings concerning PGA and their food sources are thoroughly described and discussed in this comprehensive review. Different issues, including their physical–chemical characteristics, consumption, bioavailability, and biological relevance in the context of different pathologies, are covered in detail, along with the most relevant prospective technological applications. Due to their complex structure and acyl groups, most of the PGA exhibit an overall higher stability than the monoglycosylated ones. Their versatility allows them to act in a wide range of pathologies, either by acting directly in molecular pathways or by modulating the disease environment attributing an added value to their food sources. Their recent usage for technological applications has also been particularly successful in different industry fields including food and smart packaging or in solar energy production systems. Altogether, this review aims to put into perspective the current state and future research on PGA and their food sources. © 2022 Institute of Food Technologists®.

摘要：
Anthocyanin nanoliposomes (ANLs) were produced by a thin film ultrasonic dispersion method to improve the stability and bioavailability of anthocyanins (ACNs) obtained from grape skin extracts. The preparation parameters were predicted to be a soy lecithin to cholesterol ratio of 80 : 19 (w/w, 2 mg of ACNs) under ultrasonication at 120 W for 3.12 min by the response surface methodology. Under the optimal conditions, the fabricated ANLs presented an encapsulation efficiency of 40.1% with an average particle size of 117 nm, a PDI of 0.254 and a ζ-potential of 8.56 mV. The stability of ACNs was improved by nanoliposome encapsulation under various temperature and light conditions. Moreover, a MKN-28 (stomach) barrier model was established to evaluate the cellular transport of ACNs before and after nanoliposome encapsulation. HPLC-DAD/MS analyses demonstrated that ACNs obtained from grape skin extracts mainly consisted of five monomers. After 180 min of transportation, peonidin-3-5-diglucoside and malvidin-3-5-diglucoside (two representative monomers) present in ANLs (0.5 mg mL−1) showed the maximum transport efficiencies of 17.25 ± 1.62% and 18.94 ± 1.05%, respectively. However, their maximum transport efficiencies were 11.68 ± 1.01% and 15.33 ± 1.24%, respectively, existing in ACNs (non-encapsulated form, 0.5 mg mL−1). Furthermore, the antiproliferative properties of ANLs were assessed in two cancer cell lines MKN-28 and HepG-2 (liver). The ANLs presented more effective antiproliferative effects towards MKN-28 than the HepG-2 cell line. This study provides theories and a practice foundation for further application of ACNs as nutraceutical and functional foods. © 2022 The Royal Society of Chemistry.

Chitosan oligosaccharides;Fungus;Inhibitory activity;Mechanism
摘要：
Chitosan oligosaccharides (COS) are a derivative of low molecular weight chitosan and are potent natural antimicrobial agents. The antimicrobial activity of COS against Aspergillus flavus and Aspergillus fumigatus was evaluated by minimum inhibitory concentration (MIC) and inhibition of mycelial growth. The MICs of COS against these two fungi were 31.2 and 15.6 mg/mL, respectively. COS treatment rendered fungal mycelia wrinkled and deformed with a fractured appearance. COS also increased cellular permeability leading to a significant leakage of cellular components indicating membrane damage. This compound also dose-dependently reduced chitin production and enhanced chitinase activity while enhancing the accumulation of reactive oxygen species (ROS). These characteristics suggested that COS has inhibitory effects against food spoilage fungi and acts on the cell wall and membrane and alters cellular metabolism. COS shows promise for food industry applications since it is non-toxic to higher organisms. © 2021

摘要：
In recent years, probiotics have been increasingly proposed as health-promoting supplements in variety of food systems because of their physiological function and technological characteristics. Though there are large documents concerning the health benefits from these functional microbes, only a few literatures stated the requirements for mineral enhancement in food industry. Due to the health maintenance and specific supplementary demand, this review aims at proposing the screen routes for functional microbes selection on micronutrient supplement and the action on human health. In this article, the selection strategies of different functional strains for safe dietary supplement are investigated and proposed according to the health and security legislation. Moreover, the confirmed strain as micronutrient supplement or producer, including vitamins, selenium, chromium, iron, and zinc elements were summarized and discussed. This paper also reviews the studies of probiotics widely recognized health effects and provides the practicing dietitian some basics on supplement recommendations to better serve consumers. © 2020 Taylor & Francis.

摘要：
By quenching the electronic excited state, self-aggregation of photosensitizers deteriorates the photodynamic therapy (PDT) outcome. Previously reported strategies to mitigate aggregation-caused-quenching (ACQ) involve harsh conditions and tedious synthesis processes. Moreover, failure to tune the extent of photosensitizer aggregation on-demand usually leads to a sub-optimal PDT effect. Herein, a new insight into ACQ alleviation by precisely tailoring the aggregation extent of photosensitizers via the confinement effect is unraveled by concise and facile coordination co-assembly fabrication of Pt/TCPP NCPs. Optimized meso-tetra(4-carboxyphenyl)porphine (TCPP) aggregation extent was achieved by precisely regulating the PES/TCPP feeding ratio to 12, unleashing outstanding PDT efficacy for robustly synergistic cancer PDT/chemotherapy.

摘要：
This study was aimed at investigating the structural characterization, acute toxicity and protective effect of selenylated apple pectin on dextran sulfate sodium (DSS)-induced ulcerative colitis (UC) in mice. Selenylated apple pectin was characterized by ion chromatography, NMR and SEC-RI-MALLS. The acute toxicity and protective effect of selenylated apple pectin against UC were investigated by gavage administration in mice. The organ state and coefficients, inflammatory cytokine (IL-6, IL-10 and TNF-α) contents in serum, GSH-Px activity and MPO content in colon tissues were also evaluated. The results indicated that selenylated apple pectin was non-toxic and contained 244.28 μgselenium per g. The monosaccharide composition with different molar ratios, different relative molecular weights and a weakened signal peak (CH2-O group) at 3-4 ppm were observed after selenylation. The selenylated apple pectin showed the protective effect against UC by down-regulating IL-6 and TNF-α contents and up-regulating the IL-10 content in serum, as well as increasing the GSH-Px activity and decreasing the MPO content in colon tissues. Moreover, DSS-induced alterations were effectively recovered by a high-dose sample. These findings provide evidence in support of selenylated apple pectin as a novel dietary selenium supplement for UC protection. © 2022 The Royal Society of Chemistry

摘要：
Currently, the effect of different pretreatments (i.e., radio frequency (RF), explosion puffing (EP), microwave (MW) and oven heating (OH)) on the flavor characteristics of peanut butter is unclear. Consequently, this study identified volatile aroma and non-volatile taste using HS-SPME/GC–MS combined with the use of an electronic nose, electronic tongue, and sniffing. 53 volatile compounds in four peanut butters were identified, MW-treated samples exhibited the most aroma-active compounds (43), followed by samples treated using OH (42), EP (38) and RF (21). Different pretreatment resulted in significant flavor differences in the aroma and taste. The peanut butter under MW pretreatment had a strongest nutty notes among the treatments. RF methods yielded smaller particle sizes and better texture compared to conventional OH. However, instantaneous heating using EP did not result in improvements to the aroma or taste. A combination of MW and RF may improve the flavor quality of peanut butter. © 2022 Elsevier Ltd

Food safety issues have become a major threat to public health and have garnered considerable attention. Rapid and effective detection methods are crucial for ensuring food safety. Recently, nanostructured fluorescent materials have shown considerable potential for monitoring the quality and safety of food because of their fascinating optical characteristics at the nanoscale. In this review, we first introduce biomaterials and nanomaterials for food safety analysis. Subsequently, we perform a comprehensive analysis of food safety using fluorescent biosensors based on nanomaterials, including mycotoxins, heavy metals, antibiotics, pesticide residues, foodborne pathogens, and illegal additives. Finally, we provide new insights and discuss future approaches for the development of food safety detection, with the aim of improving fluorescence detection methods for the practical application of nanomaterials to ensure food safety and protect human health. © 2022 by the authors.

摘要：
Exploring new functions of nanomaterials can help facilitate the development of biosensors for the detection of antibiotics. Herein, a new detection modality based on monovalent antigen-induced aggregation (MAA) of immunomagnetic beads (IMBs) was proposed for rapid and label-free detection of enrofloxacin (ENR), which endowed IMBs with the abilities of both sample separation and signal generation. In the presence of ENR, the initially well-dispersed IMBs were aggregated and the degree of aggregation was in a concentration-dependent manner. After exploring the mechanism underlying IMB aggregation and investigating the key parameters affecting it, a label-free biosensing platform was developed for rapid and sensitive detection of ENR. Based on the significant differences in the magnetic separation speed and size between the aggregated and well-dispersed IMBs, two methods were proposed for quantitatively determining ENR, i.e., measuring the turbidity of the IMB supernatant after magnetic separation for a given time and visualizing and calculating the grayscale value of the aggregated IMBs trapped on the surface of a nitrocellulose membrane. A three-dimensional (3D)-printed syringe was designed and fabricated for automatic filtration of IMBs. This immunosensor allowed for sensitive detection of ENR in less than 15 min without any labels. It exhibited a satisfactory limit of detection of 0.79 ng mL-1 and showed the feasibility for ENR detection of spiked chicken meat with recovery rates ranging from 74.8 to 98.3%. The MAA immunosensor can act as a promising tool to detect trace levels of ENR and has the potential to be applied to complex food samples. © 2022 American Chemical Society.

摘要：
Available literature on Chinese medicinal herbal residues (CMHRs) bioconversion highlights pretreatment prior to saccharification with cellulase without considering the presence of starch constituent. Herein, four commonly found CMHRs were tested for starch content, and it was found they all contained starch with content ranging from 4.74% to 16.78%. Hydrolysis of raw CMHRs with combined cellulase and amylolytic enzymes yielded increments of 16.85% to 26.51% in 48-h glucan conversion compared to cellulase alone. Further study showed 48-h glucan conversion of raw CMHRs outperformed that pretreated by water–ethanol successive extraction, ultrasound and acid, but underperformed alkali-pretreated CMHRs. Although increasing 48-h glucan conversion in the range of 7.40% to 24.10% compared to raw CMHRs, alkaline pretreatment demonstrated low glucose recovery and incurred additional cost, making it unfavorable. Saccharification of the four raw CMHRs with combined enzymes seems like a preferred option considering the elimination of high-cost pretreatment step. © 2022 Elsevier Ltd

摘要：
In this study, the degradation and bio-conversion of Dioscorea zingiberensis C. H. Wright solid residues (DZWSR) were performed. A large number of solid residues from Dioscorea zingiberensis C. H. Wright (DZW) are discarded or burned directly in the diosgenin industry, resulting in a serious waste of resources and environmental pollution. After dilute acid impregnation with low-pressure steam expansion (DALPSE), organic solvent extraction, enzyme hydrolysis, and other treatments, the hemicellulose degradation rate reached 94.71 %, the cellulose degradation rate increased to 88.29 %, and the fermentable sugar liquor was obtained. Compared with glucose fermentation, the ethanol yield by DZWSR hydrolysate fermentation was 83.93 %. It was found that DALPSE and the subsequent lignin extraction could break the lignocellulosic structure of DZWSR, which could effectively improve the accessibility of cellulose. This research will enhance the sustainability of the diosgenin industry and similar industries, and promote the resource utilization of biomass solid waste. © 2022 Elsevier Ltd
