In order to explore the effects of super-fast freezing (SFF) on beef quality, conventional chilling (CC, 0 ± 2 °C) and very fast chilling (VFC, hot-boned beef loins chilled at −30 °C and then stored at 0 ± 2 °C to bring the temperature down to 0 °C within 5 h post-mortem ) were used as controls to investigate the effects of three SFF treatments (−30 °C until the core temperature decreased to −3 °C (SFF–I), −7 °C (SFF–II) and − 10 °C (SFF–III), and then stored at 0 ± 2 °C until 24 h post-mortem ) on beef tenderness, meat color, water holding capacity, and other related indicators. The results showed that both SFF and VFC improved the tenderness of beef at the early stage of storage compared with CC, and of these SFF–II and SFF–III were the most effective. The SFF has the potential to reduce the cooking loss but increases the purge loss of beef. In addition, SFF has a negative effect on the meat color, but the a * value is still within the acceptable range of consumers. After being treated by SFF, the rate of beef glycolysis was delayed post-mortem . In addition, SFF treatment did not cause a large degree of shortening of sarcomere, but disrupted the muscle fiber structure, contributing to the improvement of muscle tenderness. The results indicate that pre-rigor beef muscles can be deeply frozen, which will not cause obvious shortening with proper freezing and thawing procedures.

Pectic oligosaccharides are viewed as excellent immunomodulator, but the specific molecular weight (M_w) range required for anti-inflammatory effects remains unclear. In this study, citrus pectins was depolymerized by the ultrasound/H2O2/Vc system and the pectic mixtures was separated through the superdex 30 chromatography column. Three highly purified pectin fractions (USP1, USP2, USP3) were obtained, with the M_w of 2713 g/mol, 3683 g/mol, and 7469 g/mol. All of them were RG-I pectins and USP3 contained more arabinan sidechains than USP1 and USP2. In vitro anti-inflammation assays based on LPS-induced RAW264.7 macrophages indicated that these pectins could suppress the NO release, ROS production and down-regulated the level of pro-inflammatory cytokines IL-1β, IL-6 and TNF-α in a M_w-dependent manner. The inhibitory effects increased in the order of USP1w pectins with M_w>3KD should be effective as a prophylactic agent against inflammatory diseases in functional food. © 2021

Urban agriculture, the cultivation, processing and distribution of plants and animals within urban or suburban boundaries, is becoming an increasingly relevant strategy to enhance food safety for urban residents. With the rapid urbanization in the past decades, three forms of urban agriculture have emerged in China: small-scale, capital-intensive, and tourism-type. Each form presents unique benefits and challenges, and their development has been largely shaped by the local socio-economic context and government policies. The benefits of urban agriculture are numerous including the improvement of community cohesion, promotion of physical health, enhancement of environmental sustainability, and creation of new economic opportunities. However, it also faces many challenges such as land availability, capital shortage, market access, and governmental support. This review summarized the benefits of urban agriculture and its current limitations and challenges, and proposed strategies to overcome these hurdles in China based on successful examples in the Global North. Four specific recommendations were provided to promote urban agriculture in China: integration of urban agriculture into cities, solutions for land and resource use, government support and reactions, as well as planning and regulations. Adoption these recommendations is expected to result in healthier cities and a more robust agricultural system in China. © 2024 The Author(s)

This study investigated the complexation behavior of octenyl succinic anhydride (OSA) starch (OSA-S) and chitosan (CS). According to the analysis of the turbidity, ζ-potential, optical micrographs and state diagrams, a pH-induced phase transition occurred due to the modification of the surface charge in biopolymers through ionic group dissociation. The aggregation of biopolymers was then altered to exhibit different complexation states, including co-soluble mixtures as well as soluble and insoluble complexes. An increase in substitution degree (DS) of OSA-S or OSA-S/CS mixing ratios changed the charge balance between biopolymers during complexation, leading to increased turbidity and a charge compensation-shift. The impacts of ionic strength, urea concentration, temperature and reaction time on the complexation behavior were also explored. In addition to the electrostatic interaction, hydrogen bonding and hydrophobic effects may also be involved in the complexation of OSA-S and CS. This was verified by fourier transform infrared spectroscopy and isothermal titration calorimetry. A spontaneous exothermic process of complexation was also observed by calorimetry. The information presented in our study may assist in developing polysaccharide complexes based on the comprehension of their complexation behavior. © 2021 Elsevier Ltd

Apricots rapidly ripen and senesce during storage, seriously impacting its commercialization. This work aimed to elucidate the function of cold plasma (CP) treatment on apricot fruit respiration and energy metabolism, and its relationship with fruit senescence. CP treatment significantly inhibited fruit decay, with a 54.8 % lower decay incidence than control (CK) on day 42. Compared with CK fruit, the activities of alternative oxidase (AOX), cytochrome c oxidase (CCO), succinate dehydrogenase (SDH), phosphoglucose isomerase (PGI), and hexokinase (HK), as well as their corresponding gene expression levels, were decreased in CP-treated fruit. Conversely, NAD kinase (NADK), glucose-6-phosphate dehydrogenase (G6PDH), 6-phosphogluconate dehydrogenase (6PGDH) activities and genes expression were increased. Additionally, CP-treated apricot showed lower nicotinamide adenine dinucleotide (NAD) and reduced nicotinamide adenine dinucleotide (NADH) contents and higher nicotinamide adenine dinucleotide phosphate (NADP) and reduced nicotinamide adenine dinucleotide phosphate (NADPH) contents. As regards energy metabolism, adenosine triphosphate (ATP), adenosine diphosphate (ADP) contents, energy charge (EC), and total adenosine triphosphatase (ATPase) activity in apricot were enhanced by CP treatment, while AMP content was decreased. In conclusion, CP treatment inhibited apricot fruit respiratory metabolism by downregulating the Embden–Meyerhof–Parnas pathway (EMP–TCA) cycle, the cytochrome pathway (CCP), the alternative oxidation pathway (AP), and upregulating the pentose phosphate pathway (PPP). This sustained a higher level of energy status and membrane structural integrity, and improved the preservation quality of apricot fruit.

Halogenated methanesulfonic acids (HMSAs) is an important new class of organic compounds as they were universal in the water cycle and drinking water sources. However, no study has investigated the presence of HMSAs in water and sediment from China. The present study reports the occurrence and spatiotemporal distribution of seven HMSAs in water and sediment samples from Hangzhou Bay, China. Trifluoromethanesulfonic acid (F3-MSA) was the main contributor to the concentrations of HMSAs in water and sediment samples from spring, summer, autumn and winter which were 30.8-541 ng/L, n.d.-86.6 ng/L, 4.22-70.9 ng/L and 8.86-192 ng/L, separately, while in sediment samples were n.d.-11.1 ng/g, n.d.-12.9 ng/g, n.d.-22.5 ng/g, n.d.-4.60 ng/g, respectively. The levels of HMSAs in water from winter and spring were higher than those in summer and autumn, and the concentrations of the target HMSAs in water presents a seasonal pattern affected by the temperature, the precipitation and river flow variations. Nevertheless, the levels of HMSAs in sediment were highest in the area near the industrial area and the confluences of rivers. Correlation analysis revealed that the total concentrations of HMSAs were significantly positively correlated with total organic carbon (TOC) in water samples. Although F3-MSA is regarded as low toxic based on the EC50 value of acute toxicity, the potential risks to aquatic ecology should be paid more attentions due to its high concentrations in the aquatic system and the environmental persistency. © 2022, The Authors.

Fucosylated chondroitin sulfate (FCS) polysaccharide isolated from sea cucumber has potent anticoagulant activity. Based on its resistance to the enzymes present in vertebrates, it may serve as an anticoagulant and shows antithrombotic effects when delivered through gastro-resistant (GR) tablets. However, due to the multiple plasma targets of FCS polysaccharide in the coagulation pathway, bleeding can occur after its oral administration. In the current study, we used FCS oligomers, in particular a mixture of oligosaccharides having 6 to 18 saccharide units, as the active ingredient in GR microcapsules for oral anticoagulation. In a Caco-2 model, the FCS oligomers showed higher absorption than native FCS polysaccharides. Oral administration of FCS oligomer-GR microcapsules provided a dose-dependent, prolonged anticoagulant effect with a selective inhibition of the intrinsic coagulation pathway when compared with

Nanobody(Nb) is too small to carry more signal reporters, which often leads to low sensitivity in immunoassay. Herein, we proposed a novel immunoprobe integration of Nb and biomimetic mineralized metal-organic frameworks(MOF), in which plenty of succinylated horseradish peroxidase(sHRP) were encapsulated within a single MOF and the Nb was assembled on the biomimetic mineralized MOF. It overcomes the dilemma that the Nb is difficult to carry more signal reporters. Meanwhile, the mineralized MOF can protect the sHRP from denaturation and facilitate the transport of substrates to the active sites of sHRP. Electrosensing of aflatoxin B 1 (AFB 1 ) was realized with a competitive format in which the target AFB 1 and immobilized artificial antigen were competing for binding with the immunoprobe. Additionally, the detection signal was enlarged by the catalysis of this immunoprobe to 4-chloro-1-naphthol for producing precipitations, which blocked the channels of the immunoprobe and the redox probes of Fe(CN) 6 3−/4− was difficult to reach the electrode surface through the channels. Hence, the as-prepared immunosensor exhibited good voltammetry responses towards the determined AFB 1 in a linear range of 50.0 fg/mL - 20.0 ng/mL with a detection limit of 20.0 fg/mL. The specificity, stability, and reproducibility of this immunosensor were satisfactory. This work may provide an alternative idea for the application of Nb in immunoassay, and the idea may also be applicable to other bio-recognition elements for immunoassay.

The thick electrode of zinc ion capacitors (ZICs) is limited by the performance contradiction between fast reaction kinetics and high-quality load. The key to break through this bottleneck is to clarify the multi-physical field coupling mechanism inside the electrode and reveal the synergistic energy storage law of ion cross-scale transport and interface adsorption/desorption. In this study, a “structure-interface” collaborative optimization strategy was proposed: based on the natural wood framework, a three-dimensional interconnected multi-level pore network was constructed by resin to realize the precise matching of pore size and hydrated zinc ions, and N/O diatomic doping was introduced to regulate the surface charge distribution. The WPNK2 electrode exhibits a satisfactory capacity of 5.8 mAh cm –2 and maintains 1.9 mAh cm –2 at 200 mA cm –2 . At the same time, it provides a surprising capacity of 10.9 mAh cm –2 when the load is increased to 82.75 mg cm –2 . Combined with in-situ spectroscopy, DFT, and electrochemical kinetic analysis, the multi-level energy storage mechanism of ion transport and interface adsorption in thick electrodes was revealed. This work provides a full-chain research paradigm of “structural design-interface engineering-mechanism analysis” for solving the “kinetics-load” trade-off problem of thick electrode materials, which will promote the development of high energy density ZICs devices.
