Despite its extensive use, increasing evidence has raised concerns regarding its potential adverse effects on metabolic homeostasis, including the induction of oxidative stress, hepatic inflammation, lipid accumulation, and reduced lifespan. However, whether sodium benzoate-induced obesity phenotypes can be transmitted to subsequent generations via epigenetic mechanisms remains largely unexplored. In this study, we used <em>Caenorhabditis elegans</em> as a model organism to investigate whether the high-lipid phenotype induced by sodium benzoate could be inherited epigenetically by offspring. Our results demonstrated that exposure to sodium benzoate led to a high-lipid phenotype that persisted across multiple generations through epigenetic inheritance. Mechanistically, the transcription factor SKN-1 functioned not only as an effector regulating lipid metabolism but also as a key mediator transmitting epigenetic information to progeny. Furthermore, we identified histone H3 lysine 9 trimethylation (H3K9me3) as a critical epigenetic modification underlying this transgenerational effect. Collectively, these findings indicate that sodium benzoate induces heritable lipid accumulation through the SKN-1/Nrf2 signaling pathway, accompanied by a reduction in H3K9me3 levels.</div></div>","PeriodicalId":10939,"journal":{"name":"Current Research in Food Science","volume":"12 ","pages":"Article 101299"},"PeriodicalIF":7.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145939207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Microbial communities were analyzed using amplicon (16S rRNA) and shotgun metagenomic sequencing, and metabolite profiles were determined by GC–MS to provide an integrative understanding of microbial and metabolic stability during long-term cold storage. Lower aging temperatures reduced fluctuations in metabolic and microbial activities, particularly among LAB, thereby contributing to a more stable physicochemical profile and extended shelf life. During rice wine aging, LAB exerted a more pronounced effect on metabolite dynamics than yeast, particularly for pyruvate, γ-aminobutyric acid, and lactic acid, underscoring their role in the aging process. Additionally, sub-zero aging temperatures preserved the initial microbial composition, limited enzymatic degradation, and stabilized organic acid profiles, reflecting enhanced chemical stability of the product during aging.

Many efforts have been made to prevent KSD, including the use of some dietary supplements. However, mechanisms underlying their anti-KSD properties have remained poorly understood, and their relative anti-KSD properties have previously been unknown. Herein, we systematically evaluated and compared the inhibitory effects of five well-known dietary supplements on CaOx crystals. Caffeine (CAF), epigallocatechin-3-gallate (EGCG), N-acetylcysteine (NAC), resveratrol (RES) and trigonelline (TRIG) (at 1, 10 and 100 μM, which are within their physiologic levels in the urine) were subjected to CaOx crystallization, growth and aggregation assays. Degrees of their CaOx crystal-inhibitory activities were then compared. CAF inhibited crystal formation, EGCG inhibited crystal formation and growth, NAC inhibited crystal aggregation, RES inhibited crystal growth, and TRIG inhibited crystal formation and growth. However, RES promoted crystal aggregation and thus served as a dual modulator (acting as an inhibitor and promoter at different steps of stone formation). Almost all of these inhibitory effects were concentration-dependent. Comparing the CaOx-inhibitory activities of these compounds revealed that EGCG was the most potent inhibitor against CaOx crystal formation (with the crystal abundance-inhibitory activity of 85.61 ± 5.12 %), whereas RES was the most potent inhibitor against CaOx crystal growth (with the crystal growth-inhibitory activity of 92.99 ± 1.67 %).

Simulations were conducted for conventional frying and microwave frying (at 2.45 and 5.8 GHz frequencies) of French fries. The sample location in the oil during microwave frying impacted the sample temperature, internal pressure, moisture content, etc., due to the non-uniform distribution of the electric field in the oil. Microwave frying caused rapid heating of the food matrix, a faster rise in pore pressure, and higher peak pressure values than conventional frying. The higher magnitude of pore pressure in the food during microwave frying is expected to impede oil penetration in the samples. This method reduced frying times by 33–76 % and the oil content of French fries by 3–33 % compared to conventional frying. Microwaves at 2.45 GHz frequency penetrated deeper into the food matrix than at 5.8 GHz frequency and caused the development of higher magnitudes of pore pressure. Consequently, microwave frying at 2.45 GHz led to samples with lower oil content than 5.8 GHz.

The results showed that the fusion of wavelet features with RGB images significantly improved model prediction accuracy, and that the estimation performance of XGBoost and MTL-AM was significantly higher than that of PLSR. To further improve the estimation accuracy of the farinograph quality number (FQN), the combined MTL-AM–XGBoost model achieved the highest accuracy (R<sup>2</sup> = 0.982, RMSE = 8.975, MAE = 7.087, RPD = 6.077). This study provides an effective technical solution for the non-destructive, high-throughput monitoring of wheat functional quality.</div></div>","PeriodicalId":10939,"journal":{"name":"Current Research in Food Science","volume":"12 ","pages":"Article 101329"},"PeriodicalIF":7.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146141374","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
