China has a rich history of using Red Monascus pigments, a natural series of azaphilone alkaloids, as a traditional food coloring, spanning over a thousand years. Acidic conditions, unfortunately, lead to instability, which is a significant drawback of this. A new Talaromyces amestolkiae strain was isolated during the present work, producing the azaphilone talaromycorubrin and its corresponding azaphilone alkaloid (N-MSG-talaromycorubramine). This compound demonstrated excellent stability, even at pH values below 3. As a potential natural food coloring agent for acidic foods, the azaphilone alkaloid, an alternative to Chinese traditional red Monascus pigments, boasts acidic stability. The azaphilone alkaloid's acidic stability is advantageous for the direct fermentation of N-MSG-talaromycorubramine under low pH conditions. A novel correlation between terminal carboxylation of branched carbon chains in azaphilones and their stability under acidic conditions has been established. This discovery enables the design of novel, acid-stable azaphilone alkaloids through genetic engineering methods.

Deep learning's application to vision-based food nutrition estimation is gaining momentum, attracting public interest due to its strengths in accuracy and efficiency. The RGB-D fusion network described in this paper leverages multimodal feature fusion (MMFF) and multi-scale fusion strategies for enhanced vision-based nutrition assessment. MMFF's feature fusion methodology, employing a balanced feature pyramid and convolutional block attention module, proved effective. Utilizing a feature pyramid network, multi-scale fusion combined features from various resolutions. Both enhanced the model's feature representation, leading to improved performance. In comparison to cutting-edge methodologies, the average percentage mean absolute error (PMAE) for our approach amounted to 185%. Through the utilization of the RGB-D fusion network, the PMAE of calories and mass reached 150% and 108% respectively, showcasing improvements of 38% and 81%. Furthermore, through visualization, this study examined the results of estimations for four nutrients, affirming the reliability of the method. This research played a crucial role in the development of automated food nutrient analysis (with code and models available at http//12357.4289/codes/RGB-DNet/nutrition.html).

Issues surrounding the authenticity of Ziziphi Spinosae Semen (ZSS), a valuable food source derived from seeds, have multiplied. Using electronic eye, flash gas chromatography electronic nose (Flash GC e-nose), and headspace gas chromatography-mass spectrometry (HS-GC-MS), the researchers effectively determined the adulterants and geographical origins of the ZSS in this study. The consequence was a variation in color between ZSS and adulterants, characterized by the a* value of ZSS being lower than that of the adulterants. Flash GC e-nose and HS-GC-MS detected 29 and 32 compounds in ZSS. Spicy, sweet, fruity, and herbal flavors defined the essence of ZSS. The flavor profiles of different geographical origins were shown to be influenced by five specific chemical compounds. In the HS-GC-MS analysis, the highest relative content of Hexanoic acid was observed in ZSS samples from Hebei and Shandong, whereas 24-Decadien-1-ol exhibited the highest concentration in samples from Shaanxi. This research contributed a valuable strategy for overcoming issues of authenticity in ZSS and other similar seed-based foods.

Oral administration of 14-naphthoquinones could be a contributing factor to the development of hyperuricemia and gout, potentially mediated by the activation of the enzyme xanthine oxidase (XO). 14-Naphthoquinones, stemming from dietary sources and food-borne pollutants, were selected for analyzing the structural-activity relationship (SAR) and the underlying mechanisms behind XO activation in human (HLS9) and rat (RLS9) liver S9 fractions. Electron-donating substituents on the benzene ring, or electron-withdrawing substituents on the quinone ring, as revealed by SAR analysis, enhanced the XO-activating effect of 14-naphthoquinones. The activation of XO by 14-naphthoquinones presented different activation potentials and kinetic characteristics in the context of HLS9/RLS9 cells. dysplastic dependent pathology Density functional theory calculations, coupled with molecular docking simulations, demonstrated a significant correlation between the negative logarithm of EC50 and both docking free energy and HOMO-LUMO energy gap values. The potential hazards of exposure to 14-naphthoquinones were evaluated and their implications were thoroughly discussed. Our study's conclusions offer practical guidance for managing diets in clinics, thereby preventing adverse events linked to dietary intake of 14-naphthoquinones.

Identifying pesticide residues explicitly on the surfaces of fruits and vegetables is the goal of food safety supervision. A novel surface-enhanced Raman scattering (SERS) method for the sensitive and nondestructive detection of non-systemic pesticides on the surface of fruits and vegetables was proposed in this study; the method is straightforward and easily implemented. Filter paper, modified with a layer of PDADMAC(+) and PSS(-), facilitated the electrostatic adsorption of positively charged CTAB-guided Au@Ag NRs, resulting in the formation of the composite material. Synergistic interactions within bimetallic Au@Ag nanorods (NRs) enabled their efficient adsorption onto the fiber grid, resulting in the formation of 3D SERS hotspots within a few microns of depth. The 3D composite flexible substrate showcased remarkable SERS activity, extraordinary repeatability, and high sensitivity in the detection of 4-MBA, methyl-parathion, thiram, and chlorpyrifos. The arbitrary bending of the substrate facilitated the immediate and precise identification of three different non-systemic pesticide kinds present on the fruit peel, thus showcasing the efficiency of the SERS paste-reading method. The results of the acquisition demonstrated the potential of PDADMAC/PSS/Au@Ag NRs composite filter paper for providing rapid feedback on the in situ analysis of pesticide residues present on the surface of fruits and vegetables.
