A Novel Water-Soluble Polysaccharide from Daylily (Hemerocallis citrina Baroni): Isolation, Structure Analysis, and Probiotics Adhesion Promotion Effect.

The daylily (Hemerocallis citrina Baroni) flower is a traditional raw food material that is rich in a variety of nutrients. In particular, the content of polysaccharides in daylily is abundant and has been widely used as a functional component in food, cosmetics, medicine, and other industries. However, studies on the structure-effective relationship of daylily flower polysaccharides are still lacking. In view of this, daylily flower polysaccharides were isolated and purified, and their physical and chemical properties, structure, antioxidant activity, and adhesion-promoting effect on probiotics were evaluated. The results showed that a novel water-soluble polysaccharide (DPW) with an average molecular weight (Mw) of 2.224 kDa could be successfully isolated using column chromatography. Monosaccharide composition analysis showed that DPW only comprised glucose and fructose, with a molar ratio of 0.242:0.758. Through methylation and nuclear magnetic resonance (NMR) analysis, it was inferred that DPW belonged to the fructans group with a structure of α-D-Glcp-1→2-β-D-Fruf-1→(2-β-D-Fruf-1)n→. Antioxidant analysis showed that DPW showed strong 2-Phenyl-4,4,5,5-tetramethylimidazoline-1-oxyl-3-Oxide (PTIO-scavenging activity with IC50 of 1.54 mg/mL. DPW of 1.25 to 5 mg/mL could significantly increase the adhesion rate of Lactobacillus acidophilu, Lactobacillus casei, Bifidobacterium adolescentis, and Lactobacillus plantarum on Caco-2 cells. Considering the above results, the present study provides a theoretical basis and practical support for the development and application of daylily polysaccharides as a functional active ingredient.

Botanical Impurities in the Supply Chain: A New Allergenic Risk Exacerbated by Geopolitical Challenges.

The supply chains of food raw materials have recently been heavily influenced by geopolitical events. Products that came from, or transited through, areas currently in conflict are now preferentially supplied from alternative areas. These changes may entail risks for food safety. We review the potential allergenicity of botanical impurities, specifically vegetable contaminants, with particular attention to the contamination of vegetable oils. We delve into the diverse types of botanical impurities, their sources, and the associated allergenic potential. Our analysis encompasses an evaluation of the regulatory framework governing botanical impurities in food labeling. Unintended plant-derived contaminants may manifest in raw materials during various stages of food production, processing, or storage, posing a risk of allergic reactions for individuals with established food allergies. Issues may arise from natural occurrence, cross-contamination in the supply chain, and contamination at during production. The food and food service industries are responsible for providing and preparing foods that are safe for people with food allergies: we address the challenges inherent in risk assessment of botanical impurities. The presence of botanical impurities emerges as a significant risk factor for food allergies in the 2020s. We advocate for regulatory authorities to fortify labeling requirements and develop robust risk assessment tools. These measures are necessary to enhance consumer awareness regarding the potential risks posed by these contaminants.

Rewiring Metabolic Flux in Corynebacterium glutamicum Using a CRISPR/dCpf1-Based Bifunctional Regulation System.

Corynebacterium glutamicum, a microorganism classified as generally recognized as safe for use in the industrial production of food raw materials and additives, has encountered challenges in achieving widespread adoption and popularization as microbial cell factories. These obstacles arise from the intricate nature of manipulating metabolic flux through conventional methods, such as gene knockout and enzyme overexpression. To address this challenge, we developed a CRISPR/dCpf1-based bifunctional regulation system to bidirectionally regulate the expression of multiple genes in C. glutamicum. Specifically, through fusing various transcription factors to the C-terminus of dCpf1, the resulting dCpf1-SoxS exhibited both CRISPR interference (CRISPRi) and CRISPR activation (CRISPRa) capabilities in C. glutamicum by altering the binding sites of crRNAs. The bifunctional regulation system was used to fine-tune metabolic flux from shikimic acid (SA) and l-serine biosynthesis, resulting in 27-fold and 10-fold increases in SA and l-serine production, respectively, compared to the original strain. These findings highlight the potential of the CRISPR/dCpf1-based bifunctional regulation system in effectively enhancing the yield of target products in C. glutamicum.

Unveiling the hub genes associated with ochratoxin A-induced hepatotoxicity in broiler chickens.

Ochratoxin A (OTA) widely exists in raw food and feed materials and can induce liver damage and toxicity. However, the mechanisms of OTA-induced hepatotoxicity were largely unknown. Thus, our study aimed to uncover the vital genes relevant to OTA-induced hepatotoxicity in broiler chickens. Gene expression data of chicken embryo primary hepatocytes (CEPHs) in OTA-treated and control groups were obtained from the GEO database. Totally 1407 differentially expressed genes (DEGs) were selected, of which 850 and 557 genes were up- and downregulated in OTA-treated CEPHs. Gene ontology (GO) enrichment revealed that the DEGs were in connection with various biological processes, such as signal transduction, extracellular matrix organization, axon guidance, cell division, cholesterol homeostasis, proteolysis, microtubule cytoskeleton organization, and chromosome segregation. Pathway enrichment showed that the DEGs were related to metabolic pathways, ferroptosis, calcium, FoxO, Wnt, cell cycle, apoptosis, calcium, and cell adhesion molecules signaling pathways. Furthermore, the hub genes, including CDK1, DLGAP5, KIF2C, VCL, ITGB3, and ZYX, were identified as hub genes potentially contributing to OTA-induced hepatotoxicity. Taken together, this study provides valuable insights into the mechanisms underlying OTA-induced hepatotoxicity in broiler chickens.

Rosebay Willowherb (Chamerion angustifolium) in Food Products: Evaluation of the Residual Anti-radical Activity of Polyphenol Compounds and N-acetylcystein

Background: The composition of polyphenolic compounds in various parts of the Rosebay willowherb (Chamerion angustifolium) has been studied in detail and published. A number of these compounds have sufficient antiradical activity (ARA) to create functional foods based on extracts from this plant that are preventive against free-radical pathologies in humans. Part of substances with antiradical activity (e.g., vitamins, polyphenol components) are destroyed during the technological processing of food raw materials, and the values of ARA drop in the finished food product concerning the initial values (before and after technical processing) are not fully evaluated. Objective: The object of the study is to study the thermal stability of polyphenol components possessing ARA (dried at 60°C and 150°C) and evaluate their residual ARA in the finished food products, N-acetylcysteine (NAC), as one of the known antiradical, was used as a reference substance. Methods: Spectrophotometric method was used to evaluate the change of ARA in prepared foods. Gas chromatography-mass spectrometry (GC-MS) was used as an additional method to evaluate the difference in the chemical composition of polyphenol components. Results: The residual ARA in the finished products (for caramel and bakery products) was ≈ 23.9% for rapidly extractable substances, for polyphenol compounds ≈ 46.1%, and for amino acids and easily hydrolyzable substances ≈ 34.5%. Conclusion: Rosebay willowherb extract and N-acetylcysteine are recommended for increasing the ARA (between 1.6-4.9 times) of foods with low ARA (confectionery, bread, or other heavily processed foods) and for diets and diets preventive of free-radical pathologies by adding polyphenolic plant components and cysteine derivatives.

Molecular genetic methods for identifying raw materials in meat products: Diversity, opportunities and prospects

In the current economic situation, after easing the Covid pandemic restrictions, almost all laboratories, which are focused on evaluation of the conformity of food products, have faced issues in supplying for their laboratories. In this regard, in the last years many laboratories have been forced to validate new approaches and introduce new methods for assessing conformity of the food products. Very often it is not possible to use only one method to resolve the issue of the food product ingredients, especially for the purpose of traceability of their names and the used raw materials, listed on the label. Survey of the raw food materials to determine whether they correspond to the type name is a simpler task, in contrast to survey of the multicomponent food product. Many researchers have to estimate the opportunities and feasibility of application of various methodologies in their workplaces. Therefore, this review is relevant for the researchers in this field, as it focuses on aspects and special features of similar methodologies. The prospect of molecular genetic methods for identification of the raw materials used for manufacturing of meat products is presented below. This review also represents characteristics of methods for identification of the sources of raw materials used for the manufacturing of the meat products, based on the recognition of species-specific sections within the nucleic acids structures. The variety of methods (hybridization methods, polymerase chain reaction, different types of isothermal amplifications, methods using CRISPR/Cas systems), the principles of their implementation, and achieved analytical characteristics are considered. The capacities and competitive potential of various methods are discussed, as well as approaches being developed to overcome the existing limitations.

Discovery of antitussive material basis and mechanisms in Citri Sarcodactylis Fructus by coupling UHPLC-Q/Orbitrap HRMS combined spectrum-effect relationship and metabolomics analyses

Citri Sarcodactylis Fructus (CSF) is widely used as food raw material and traditional Chinese medicine. Fingerprints of different fractions of CSF were established for spectrum-effect relationship analysis, and the main compounds were identified by UHPLC Quadrupole Orbitrap high-resolution mass spectrometry (UHPLC-Q/Orbitrap HRMS). The antitussive effect was evaluated using a classical mouse model of cough induced by ammonia water. One-way ANOVA was used to determine differences in efficacy. The potential active compounds were screened by spectrum-effect relationship with grey relational degree analysis (GRA), Pearson bivariate correlation analysis (Pearson's), and partial least squares analysis (PLS) analyses. Differential metabolites associated with cough in serum were screened and identified using orthogonal partial least squares-discriminant analysis, HMDB database, and UHPLC-Q/Orbitrap HRMS. Metabolic pathway analysis was performed using MetaboAnalyst 5.0. Results indicate that 70 % ethanol elution fraction (70 % EF) is the major active fraction, and 8 components were identified to possess antitussive effects. Metabolomic analysis showed that 19 metabolites are potential biomarkers related to cough, and 70 % EF can remarkable restore 13 of them to normal levels (P < 0.05). These biomarkers are mainly involved in glycerophospholipid metabolism and sphingolipid metabolism. This study aims to reveal the main pharmacodynamic active sites and potential active ingredients of CSF's antitussive effect. In addition, metabolomics was used to preliminarily elucidate the in-vivo regulatory mechanism of the antitussive effect of the 70 % EF of CSF.

ИЗУЧЕНИЕ ЭФФЕКТИВНОСТИ ДЕЗИНФИЦИРУЮЩИХ СРЕДСТВ ПРИ АСКОСФЕРОЗЕ ПЧЕЛ

Ascospherosis of bees is an infectious disease that leads to the weakening and death of bee colonies and causes serious economic damage to the beekeeping industry. The purpose of this work was to study the effectiveness of modern environmentally friendly disinfectants for ascospherosis of bees in laboratory and apiary conditions. The studies were carried out in accordance with wellknown instructions, methodological requirements and methods. Based on literature data, a number of preparations were selected that have fungicidal and sporicidal effects, decompose on work surfaces to non-toxic compounds, penetrate into porous materials, are easily washed off with water and do not leave a persistent odor. At the same time, the final commercial beekeeping products must remain sanitary and biologically safe and suitable as food raw materials and products. Based on the results of laboratory studies and apiary tests of selected preparations, effective regimes were selected that ensure reliable disinfection of beekeeping objects in case of ascospherosis of bees.

Modulation of cecal microbiota and fecal metabolism in mice by walnut protein.

Walnut meal is a by-product of walnut oil pressing, in which the protein content is more than 40%, which is an excellent food raw material, but at present, it is basically used as animal feed or discarded, which results in a great waste of resources, and its modulating effect on the intestinal microbiota is not clear. In this study, we used supercritically extracted walnut meal as a raw material, prepared walnut meal isolate protein (WP) by alkaline extraction and acid precipitation, and systematically analyzed its structure by Fourier infrared spectroscopy (FTIR), Raman spectroscopy (Raman), and scanning electron microscopy (SEM); meanwhile, we explored the effects of WP on the cecal bacterial flora and fecal metabolites of mice by microbiological and metabolomic techniques. The results showed that the protein content of WP prepared using alkaline extraction and acid precipitation was as high as 83.7%, in which arginine and glutamic acid were abundant, and it has the potential to be used as a raw material for weight-loss meal replacement food; FTIR and Raman analyses showed that the absorption peaks of WP's characteristic functional groups were obvious, and that the content of the α-helix and β-fold in the secondary structure was greater than 30%, which indicated that it was structurally stable; differential scanning calorimetry (DSC) and SEM analyses showed that WP is a typical spherical particle, its denaturation temperature is 73.6 °C, and it has good thermal stability. Supplementation of WP significantly altered the composition of the intestinal flora in mice, with an increase in beneficial bacteria and a decrease in harmful bacteria; the strongest modulation of the intestinal flora was achieved by altering the composition of the intestinal flora and by increasing the number of Akkermansia (p < 0.01), which consequently affects the function of the microbiota. Based on LC-MS metabolomic results, we identified a total of 87 WP-regulated metabolites, mainly enriched in the bile secretion pathway, which had the highest relevance, followed by benzoxazine biosynthesis. In summary, walnut protein is an important plant protein and has a positive impact on intestinal health, which may provide new ideas for the development of functional foods.

Identification of Orthosiphon stamineus from different phytogeographical zones in Indonesia by FTIR-fingerprinting and chemometrics

Orthosiphon stamineus (OS) or cat’s whiskers (Lamiaceae) is one of the herbs broadly used as raw materials for functional food and traditional remedies, for it contains phenolic acids and flavonoids. OS grows well in tropical and subtropical regions of Asia and Africa. Phytogeographical characteristics are among many variables that greatly control plant growth and phytochemical content. This research was conducted to analyze and classify 14 samples of OS leaves from different regions in Indonesia according to phytogeographic profiles using a combination of Fourier-transform infrared (FTIR) fingerprinting and chemometrics, i.e., principal component analysis (PCA) and cluster analysis (CA). The first two PCs were used to show the grouping of 14 samples with a cumulative variance at 91%. Results showed that all samples had comparable FTIR spectra showing the stretching frequencies of O-H, C-H, and C=C bonds. Further discrimination with PCA and CA was able to classify them into four groups of different phytogeographical origins: group 1 comprised OS samples from Tawangmangu, Mojokerto, Batu, Sampang, Madiun, South Jakarta, Jombang, Surabaya, Kediri, and Ngawi, group 2 from Lampung and Gresik, group 3 from Badung, and group 4 from Kotabaru. Thus, it can be inferred that FTIR fingerprinting combined with chemometrics can distinguish between OS crude drugs from different locations. Introducing a wider variety of OS analytical methods is believed to positively influence the flexibility and ease of quality control of herbal ingredients, ultimately ensuring the safety and efficacy of herbal medicinal products.

Integration of food raw materials, food microbiology, and food additives: systematic research and comprehensive insights into sweet sorghum juice, Clostridium tyrobutyricum TGL-A236 and bio-butyric acid.

Sweet sorghum juice is a typical production feedstock for natural, eco-friendly sweeteners and beverages. Clostridium tyrobutyricum is one of the widely used microorganisms in the food industry, and its principal product, bio-butyric acid is an important food additive. There are no published reports of Clostridium tyrobutyricum producing butyric acid using SSJ as the sole substrate without adding exogenous substances, which could reach a food-additive grade. This study focuses on tailoring a cost-effective, safe, and sustainable process and strategy for their production and application. This study modeled the enzymolysis of non-reducing sugars via the first/second-order kinetics and added food-grade diatomite to the hydrolysate. Qualitative and quantitative analysis were performed using high-performance liquid chromatography, gas chromatography-mass spectrometer, full-scale laser diffraction method, ultra-performance liquid chromatography-tandem mass spectrometry, the cell double-staining assay, transmission electron microscopy, and Oxford nanopore technology sequencing. Quantitative real-time polymerase chain reaction, pathway and process enrichment analysis, and homology modeling were conducted for mutant genes. The treated sweet sorghum juice showed promising results, containing 70.60 g/L glucose and 63.09 g/L fructose, with a sucrose hydrolysis rate of 98.29% and a minimal sucrose loss rate of 0.87%. Furthermore, 99.62% of the colloidal particles and 82.13% of the starch particles were removed, and the concentrations of hazardous substances were effectively reduced. A food microorganism Clostridium tyrobutyricum TGL-A236 with deep utilization value was developed, which showed superior performance by converting 30.65% glucose and 37.22% fructose to 24.1364 g/L bio-butyric acid in a treated sweet sorghum juice (1:1 dilution) fermentation broth. This titer was 2.12 times higher than that of the original strain, with a butyric acid selectivity of 86.36%. Finally, the Genome atlas view, Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and evolutionary genealogy of genes: Non-supervised Orthologous (eggNOG) functional annotations, three-dimensional structure and protein cavity prediction of five non-synonymous variant genes were obtained. This study not only includes a systematic process flow and in-depth elucidation of relevant mechanisms but also provides a new strategy for green processing of food raw materials, improving food microbial performance, and ensuring the safe production of food additives.

The aim of this study is to investigate whether milk fermented by Lactiplantibacillus plantarum K79, which exhibits angiotensin-converting enzyme inhibitory activity, has an effect on lowering the blood pressure of hypertensive rats and to investigate biomarker changes in their blood. Experimental group: normal group (NG, Wistar-Kyoto rats): distilled water, control group [NCG, spontaneously hypertensive rats (SHR)]: distilled water, high treatment group (HTG, SHR): 500 mg/kg/day, medium treatment group (SHR): 335 mg/kg/day, low treatment group (SHR): 170 mg/kg/day, positive control group (PCG, SHR): Enalapril, 10 mg/kg/day. The experimental animals used in this study were divided into groups composed of 8 animals. In terms of weight change, a significant difference was observed between the NG and the SHR group, but there was no significant difference between the SHR group. After 8 wk of feeding, blood pressure was lowered more significantly in the HTG (209.9±13.3 mmHg) than in the NCG (230.8±7.3 mmHg). The treatment group has an effect of lowering blood pressure by significantly suppressing blood pressure-related biomarker protein expression than NG. The results obtained can be used as an antihypertensive material in a variety of food raw materials.
