However, excessive foam formation can hinder fermentation efficiency. This study compares two Y. lipolytica strains, F4 and 167, which exhibit distinct abilities to produce erythritol and generate foam. After 96 hours of fermentation, F4 produced 2.28 times more erythritol than 167 and generated foam with greater persistence. Foam stability testing revealed that foam produced by F4 exhibited a higher initial height and a longer half-life, indicating superior foam stability. Metabolomic profiling showed higher levels of phosphatidylcholine and phosphatidylethanolamine in F4, which were consistent with lower interfacial tension and stronger foam stability. Additionally, F4 showed enrichment of amino-acid-related metabolic features, particularly those involving alanine, aspartate, and glutamate. Genomic analysis identified strain-specific differences in genes related to cell wall biogenesis and lipid biosynthesis. These findings indicate that the stronger foam stability observed in F4 is more consistent with lipid-associated interfacial activity, whereas the higher erythritol accumulation is consistent with stronger reducing power through the pentose phosphate pathway. Total protein concentration and apparent viscosity showed opposite trends relative to foam stability, suggesting that foam persistence was more closely associated with interfacial properties than with bulk viscosity or protein content under the tested conditions. These insights can provide a theoretical basis for optimizing industrial erythritol fermentation processes.","PeriodicalId":12427,"journal":{"name":"Food Quality and Safety","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148305547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results indicated that treatment with 1 mmol L-1 SA effectively preserved appearance, reduced decay incidence, delayed firmness decline, and maintained higher levels of total soluble solids (TSS) and titratable acidity (TA). Additionally, SA significantly slowed the degradation of total phenols, total flavonoids, and anthocyanins, while increasing the levels of phenolic acids, including chlorogenic acid, caffeic acid, and ferulic acid. Concurrently, SA mitigated aroma loss by sustaining higher levels of key volatile organic compounds (VOCs) such as linalool and geraniol. Further analysis revealed that SA maintained the stability of VOCs by inhibiting the activities of phospholipase A (PLA) and lipoxygenase (LOX), and modulating the activities of hydroperoxide lyase (HPL), alcohol dehydrogenase (ADH), and alcohol acyltransferase (AAT).

In this study, the regulatory mechanism of thymol pre-harvest treatment on the quality and ascorbic acid-glutathione (AsA-GSH) cycle of blueberries during storage was investigated. The results demonstrated that thymol treatment impeded the decline of total flavonoids, total phenols, reducing sugars, and starch content in blueberry fruit. In addition, thymol treatment suppressed the activities of α-amylase, β-amylase, and total amylase. In addition, thymol increased the activities of ascorbate peroxidase (APX), glutathione reductase (GR), monodehydroascorbate reductase (MDHAR), and dehydroascorbate reductase (DHAR) and maintained high AsA and GSH contents and AsA/(AsA + DHA) and GSH/(GSH + oxidized glutathione (GSSG)) ratios in blueberries. In conclusion, thymol improved the overall postharvest antioxidant capacity of blueberries and maintained their quality by delaying the reduction of antioxidants, inducing antioxidant enzyme activities, and enhancing the metabolic activities of the AsA-GSH cycle. Therefore, thymol pre-harvest treatment can serve as an efficient and natural pre-harvest treatment agent for preserving postharvest blueberry quality, effectively maintaining the post-harvest quality of blueberries and extending their storage life.","PeriodicalId":12427,"journal":{"name":"Food Quality and Safety","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148305773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, the mechanisms underlying their emotional effects have not been fully elucidated. This study introduces an integrative approach combining subjective evaluation using the emotion and odor scale and intelligent sensory detection technologies, including electrocardiogram (ECG), electrodermal activity (EDA), and electroencephalography (EEG), to systematically evaluate the emotional effects of citrus aromas. Multimodal analysis demonstrated that citrus EOs significantly decreased the low frequency to high frequency power (LF/HF) ratio, indicating enhanced parasympathetic activity linked to relaxation and mood improvement. EEG findings revealed increased power in the α (8-13 Hz) and δ (0.5-4 Hz) bands. Notably, navel orange, blood orange, and grapefruit EOs elicited pronounced α-band activation in the frontal, right parietal, and occipital regions. These EOs also enhanced hemispheric asymmetry in the parietal and occipital lobes, which are correlated with positive emotional regulation. Through integrated analysis of multimodal data and flavoromics (chromatography-olfactometry-mass spectrometry, odor activity value) data, ᴅ-limonene, linalool, α-terpineol, and geranial were identified as key bioactive volatiles associated with improved emotional outcomes. By liking aroma profiling with physiological and neural markers, this study shows how citrus volatiles influence mood, highlighting their potential application in functional foods and nutraceutical applications.","PeriodicalId":12427,"journal":{"name":"Food Quality and Safety","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147382032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Widely targeted metabolomic analysis revealed 2906 nonvolatile metabolites, 31 of which were specific to taste tomatoes. Among these genes, 725 differentially accumulated metabolites (DAMs) were identified, while transcriptomic analysis revealed 3944 differentially expressed genes (DEGs), which included 987 upregulated and 2957 downregulated genes in taste tomatoes compared with those in ordinary tomatoes. KEGG pathway enrichment analysis indicated that the DAMs were significantly enriched in pathways associated with starch and sucrose metabolism, phenylalanine metabolism, and other pathways closely linked to flavor. Furthermore, the DEGs were significantly enriched in critical pathways, including starch and sucrose metabolism; alanine, aspartate, and glutamate metabolism; and carotenoid biosynthesis. A combined analysis revealed a strong correlation between the expression of DAMs and their corresponding genes, particularly highlighting coordinated changes among trehalose, sucrose, sucrose-6-phosphate, and their associated genes. Taste tomatoes enhance fruit flavor quality by synergistically regulating multiple key genes in pathways related to sucrose-starch metabolism, amino acid metabolism, and linoleic acid metabolism. This study identifies the core differentially abundant metabolites and molecular mechanisms underlying the formation of taste tomato quality traits, thus providing a theoretical foundation for quality improvement and market promotion.","PeriodicalId":12427,"journal":{"name":"Food Quality and Safety","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147898210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared with IR-modified starch (IRS), the synergistic sample (SEDIR) showed superior thermal stability (no gelatinization at 95 °C), a significantly reduced Rapid Visco Analyzer (RVA) recovery value of 4.05 mPa·s, and a 35% increase in resistance to digestion. These improvements were attributed to ED disrupting the branched structure and exposing hydroxyl groups, which facilitated subsequent IR esterification and increased substitution degree. Hydrolysis and digestion rates followed the order of native corn starch&gt;IRS&gt;EDS&gt;SEDIR, indicating that ED promoted amorphous degradation, while IR enhanced steric hindrance, delaying enzymatic digestion. Overall, ED followed by citric acid–IR esterification represents an efficient approach for preparing high-resistant starch with promising applications in the food industry.","PeriodicalId":12427,"journal":{"name":"Food Quality and Safety","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148305546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we screened six dietary polysaccharides in vitro and identified sodium alginate as the most effective candidate for promoting microbial uric acid degradation. Metagenomic analysis of fermentation broth revealed that sodium alginate specifically enriched uricolytic species, including Anaerostipes caccae, Dorea formicigenerans, Clostridium sp., and Enterococcus faecalis. In hyperuricemic mice, sodium alginate significantly lowered serum uric acid levels and provided renal and hepatic protection. Mechanistically, sodium alginate remodeled the gut ecosystem by boosting urate-metabolizing taxa such as Blautia, Collinsella, and Alistipes while upregulating the intestinal transporter ABCG2. Notably, fecal uric acid levels decreased despite increased intestinal secretion, confirming that sodium alginate promotes microbial decomposition rather than simple excretion. These findings establish sodium alginate as a safe and sustainable prebiotic for managing hyperuricemia. Moreover, they offer a novel screening strategy for identifying effective polysaccharides based on their ability to restore the host's intestinal urate-degrading capacity.","PeriodicalId":12427,"journal":{"name":"Food Quality and Safety","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148408626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluated the effects of the synthetic SL analog 7FGR24 on the quality and storability of fresh G. elata. The application of 10 μmol/L 7FGR24 effectively suppressed tuber germination, stabilized gastrodin and p-hydroxybenzyl alcohol levels, and improved overall tuber quality. Compared with the control, 7FGR24 significantly reduced respiratory intensity, weight loss, and hardness degradation, while enhancing soluble solids and titratable acidity. Additionally, 7FGR24 inhibited peroxidase and polyphenol oxidase activities, decreased malondialdehyde levels, and improved antioxidant capacity by enhancing 2,2-diphenyl-1-picrylhydrazyl scavenging and superoxide dismutase activity. Hormonal analysis revealed elevated indole-3-acetic acid levels and reduced gibberellin A3 and jasmonic acid contents. Weighted gene co-expression network analysis identified MYC2 as a core transcription factor potentially interacting with MYB4, ZAT10, and PUB20/21 to regulate tuber germination and anti-oxidative responses. Dual-luciferase reporter assays confirmed that MYC2 can transactivate the promoters of these target genes.

Key quality attributes, including purity, content, moisture levels, thermal stability, and biological activity, were systematically assessed. Results show that NAMPT-synthesized NMN consistently achieves 100% purity, matching pharmaceutical-grade standards, while NRK-synthesized NMN displays batch-dependent variability, with purity ranging from 92.13% to 96.19%. Stability analysis reveals that NAMPT-derived NMN maintains high thermal stability, whereas NRK-derived NMN undergoes significant physical and chemical degradation at elevated temperatures, with nicotinamide as the primary degradation product. Additionally, bioactivity testing demonstrated that NAMPT-derived NMN retains significantly higher biological activity compared with NRK-synthesized and commercial NMN.
