This study evaluated the effects of Turkish sea buckthorn fruit extracts of different polarities on breast (MCF-7) and colorectal (HT-29) cancer cells compared with non-tumorigenic MCF-10 A and FHC cells. According to our results, the ethanolic extract showed stronger cytotoxicity toward cancer cells, with IC50 values of 0.13 and 0.10 µg/mL in MCF-7 cells and 0.18 and 0.076 µg/mL in HT-29 cells after 24 and 72 h, respectively, while showing higher IC50 values in non-tumorigenic counterparts. The highest selectivity index was observed for the ethanolic extract in breast cells after 24 h (SI = 11.35). In addition, the extracts increased ROS production up to approximately 2-fold in cancer cells and induced apoptotic cell death, with marked increases in early and late apoptotic populations, particularly in MCF-7 and HT-29 cells.

To address the challenges in Chinese dish detection, including complex backgrounds, multiple coexisting dishes, difficulty in detecting small objects, and poor adaptability of existing methods, this study proposes a task-oriented detection network named CRD-DETR. The proposed method integrates three complementary modules—Coordinate Attention (CA), Receptive Field Attention Convolution (RFAConv), and Dynamic Position Bias (DPB)—at different representation stages to enhance local feature extraction and spatial relationship modeling. To validate the effectiveness of the proposed method, experiments were conducted on a self-constructed and manually annotated dataset named CDish39, which was collected in a real-world cafeteria environment. The results demonstrate that CRD-DETR achieves a 4.7% improvement in the mAP@0.5:0.95 metric compared to baseline and state-of-the-art models. Furthermore, ablation studies confirm the individual and combined effectiveness of the integrated modules.

Films were prepared by incorporating RP extract at varying concentrations (4%, 8%, and 12% w/w) into gelatin films. FTIR analysis showed the formation of hydrogen bonding interactions between polyphenolic compounds of RP and the gelatin matrix. The incorporation of RP significantly improved the UV-barrier capacity; however, mechanical analysis revealed a dose-dependent decrease in tensile strength due to structural disruptions in the gelatin network at higher extract concentrations. The developed films exhibited a sensitive halochromic response between the pH 1.0 and 13.0, characterized by the structural transition of anthocyanins from flavylium cations to chalcone forms. Prior to film incorporation, the biological safety and antioxidant efficacy of the free RP extract were validated in an in vivo zebrafish (<i>Danio rerio</i>) model, demonstrating that the extract dose-dependently mitigated AAPH-induced oxidative stress, suppressed ROS accumulation, and normalized pericardial edema. Storage trials have shown a high correlation between the total color change of the films and the microbial load, pH increase, and lipid oxidation in the fish meat. This feature reveals that the films have significant potential for use as real-time freshness indicators.

Beetroot wine samples were subjected to different treatments, and color and compositional changes were evaluated at regular intervals. Key parameters measured included betalain content, browning index, polyphenol oxidase activity, sensory color attributes, total phenolic content, and antioxidant capacity using standard analytical methods. Color retention decreased significantly during storage, following first-order reaction kinetics (R<sup>2</sup> &gt; 0.82), with betacyanin degrading faster than betaxanthin.

Reflectance and transmittance hyperspectral images were acquired from 72 independent sample units covering 12 categories across three aroma types and different quality grades, and 1728 ROI-level mean spectra were extracted.

First, using a hyperspectral system, the reflectance spectral data of azuki bean samples were collected within the 900–1700 nm wavelength range, covering six major producing origins in China. To reduce noise interference and streamline the data, the average spectrum of the region of interest (ROI) was extracted. Second, a spectral feature calculation module (SFCM) was designed. It incorporates convolutional mechanisms, spatial attention, channel attention, and self-attention mechanisms. This module first performed local feature extraction, then conducted multidimensional optimization, and finally realized global correlation fusion, automatically uncovering deep discriminative features. Finally, an end-to-end SFCC-Net classification network was constructed based on the SFCM. Through structural optimization, ablation studies, and performance comparison with state-of-the-art spectral data classification methods, SFCC-Net achieved an accuracy of 98.00%, a precision of 98.11%, a recall of 97.89%, and an F1-score of 98.10%, while also attaining the optimal classification stability.

Xindu PFEO showed maximum scavenging rates of 62.33%, 92.33%, and 37.33% against DPPH•, ABTS•⁺, and NaNO₂, respectively. Both Xindu PFEO and its major component, farnesol, exhibited inhibitory activity against 5-LOX. Furthermore, 40 µM farnesol significantly suppressed the expression of IL-1β, IL-6, and TNF-α in LPS-induced RAW 264.7 cells. These findings improve the understanding of varietal differences and bioactivities of PFEO and provide a basis for the development of PFEO-based functional foods.</p></div>","PeriodicalId":631,"journal":{"name":"Journal of Food Measurement and Characterization","volume":"20 8","pages":"15261 - 15272"},"PeriodicalIF":3.6,"publicationDate":"2026-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148871631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
