In this research, nanostructured lipid carriers (NLCs) loaded with limonene were developed using various solid lipids. The impact of high temperatures on the characteristics of NLCs was investigated. NLCs exhibited zeta potential values exceeding |30| mV, indicating excellent homogeneity and stability. Increasing the carbon chain length of monoglycerides from C15 to C21 resulted in a corresponding increase in particle size of NLCs from 219.1 ± 1.1 to 243.3 ± 0.9 nm. However, the particle size remained relatively constant with an increase in the number of solid lipid carbon chains. Encapsulation efficiency of limonene increased from 66.0 ± 0.7% to 86.2 ± 0.8% with an increase in the number of solid lipid carbon chains. The result showed that more ester bonds facilitated the dissolution of the target and enhanced the interaction forces between solid lipids and the target. X-ray diffraction, Fourier transform-infra-red spectroscopy and differential scanning calorimetry analyses confirmed effective encapsulation of limonene in NLCs, resulting in good stability. NLCs prepared from various solid lipids exhibited varying properties. Glycerol triglyceride demonstrated superior stability and homogeneity of nanoparticles under high-temperature conditions compared to other solid lipids. This study provides enhancing the thermal stability of limonene-loaded NLCs and proposes a novel approach for their practical application.

This study aimed to create a reduced-salt version of Chaozhou beef meatballs (CBMs) by employing ultrasound treatment (0 and 30 min) combined with sodium bicarbonate (0%, 0.15%, and 0.3%). The ultrasound-assisted sodium bicarbonate treatment significantly enhanced pH, salt-soluble protein solubility (SSP), water-holding capacity (WHC), and storage modulus (G′) of the CBMs (p < 0.05). Specifically, after treatment, the increase in pH value promoted the solubilization of SSP, with the content increasing from 28.23% to 56.53%. Moreover, the initial relaxation times (T₂₁ and T₂₂) were shortened, indicating a decrease in water mobility, as evidenced by an increase in WHC from 85% to 87%. Furthermore, the ultrasound treatment effectively facilitated protein unfolding, increased β-sheet secondary structure content, augmented hydrogen and disulfide bond proportions, and resulted in a denser and more uniform gel structure. Consequently, the hardness of the CBMs was significantly improved (p < 0.05). Sensory evaluation revealed that the treated reduced-salt CBMs were comparable to those produced by conventional methods. Therefore, combining sodium bicarbonate with ultrasound treatment is a viable approach to mitigate the negative effects of reduced salt content and produce high-quality reduced-salt CBMs.

Human intestinal gut microbiota harbors complex and diverse microbes that play an important role in maintaining the homeostasis of the intestinal microenvironment in humans. The rise in mortality and morbidity rates among humans because of the increased incidence of food-borne pathogens and the habits of individuals to eat junk food poses greater concerns and needs to be addressed. Bioengineering of probiotics has enabled the researchers to advance their research by developing probiotics with more functionalities. Moreover, GLP-1 peptides which are incretin hormones have been shown to be more effective when combined with engineered probiotics. Various studies have shown its effectiveness in diabetic mice where human-modified GLP-1 produced long-lasting benefits and research is going on to study its role in other diseases. The role of designer probiotics in treating and preventing diseases have been of much interest in recent times. However, the role of GLP-1 peptides in treating diseases and their efficacy in combination with next-gen biotherapeutics have received little attention. Thus, this review enlightens about the baseline knowledge as well as knowledge gaps related to conventional and genetically engineered probiotics. It also discusses the effect of GLP-1 peptides in combination with bioengineered probiotics to prevent and treat diseases.

The freshness of aquatic products is directly related to the safety and health of the people. Traditional methods of detecting the freshness of Conger myriaster rely on manual operations, which are labor-intensive, inefficient, and highly subjective. This paper combines computer vision and the DWG-YOLOv8 network model to establish an intelligent classification method for C. myriaster freshness. Through image augmentation, 484 C. myriaster samples were expanded to 2904 samples. The YOLOv8n model was improved by simplifying the network backbone, introducing Ghost convolution and the new DW-GhostConv, thereby reducing the number of parameters and computational load. Test results show that the recognition accuracy of the DWG-YOLOv8 model reached 98.958%, outperforming models such as ResNet18, Mobilenetv3 small, and Swin transformer v2 tiny. The model's parameter count is 16.609 K, the inference time is 57.80 ms, and the model size is only 102 KB. The research provides a reliable method for online intelligent and nondestructive detection of C. myriaster freshness.

The processing of vegetables generates by-products that are abundant in polyphenols and antioxidants. However, they degrade rapidly due to poor management and a short life expectancy. The present study aimed to evaluate the effect of in vitro digestion (IVD) on the phenolic compositions, antioxidant properties, and polyphenolic profile of the beetroot pomace (BP), carrot pomace (CP), and tomato pomace (TP) by-products. The results showed a reduction in phenolic compositions for total phenolic content (TPC), total flavonoid content (TFC), total anthocyanin content (TAC), and total proanthocyanidin content (TPAC), which ranged between 27.55% and 63.34%, 16.38% and 31.43%, 32.58% and 77.41%, and 28.81% and 60.78%, after IVD, respectively. Similarly, antioxidant activity evaluated by 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2′-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS^•+), Ferric-reducing antioxidant power (FRAP), metal chelating activity (MCA), and reducing power (RP), also showed a reduction. High-performance liquid chromatography with photodiode array detection (HPLC-DAD) analysis of individual polyphenols varied widely for free and bound phenolic fractions of samples. Among the polyphenolic fractions, catechin (CAT) and protocatechuic acid (PCA) were the highest in BP and CP, respectively in free forms, has shown to be increased after gastrointestinal digestion. Naringenin (NAR) was recorded with the highest both in their free and bound forms in TP and reduced postdigestion. To the best of our knowledge, the present study is the first report to evaluate the effect of IVD on free and bound individual polyphenolic content in evaluated samples.

Investigating the anti-inflammatory effects of bioactive components present in cold-pressed rapeseed oil through the use of network pharmacology and molecular docking methods. The components of cold-pressed rapeseed oil were identified by liquid chromatography-mass spectrometry. We then conducted Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis using bioinformatics databases on overlapping targets affected by active components and inflammation. Finally, molecular docking was used to predict the interactions between core components and key targets. Analysis identified 13 phenols, four steroids, and one retinoid in cold-pressed rapeseed oil, with 143 overlapping targets related to inflammation. Bioinformatics analysis revealed that 25-Hydroxycholesterol, Rosmarinic acid, 9-cis-Retinoic acid, Soyasapogenol B and α-Tocopherol in cold-pressed rapeseed oil could play a positive role in treating inflammation. They achieved this by regulating key targets (MMP9, EGFR, AKT1, ESR1, and PTGS2) involved in the peroxisome proliferator-activated receptor signaling pathway and other related pathways. The molecular docking binding energy of the core components and the key targets were less than −5.0 kcal/mol, indicating that the components and the targets can be stably bound. This result indicated that the active components found in cold-pressed rapeseed oil may exert an anti-inflammatory effect through a synergistic mechanism involving multicomponent, multitarget and multipathway interactions.

Nucleotides, such as uridine 5′-monophosphate (5′-UMP) and cytidine 5′-monophosphate (5′-CMP), are heavily demanded as food additives, dietary supplements, and medicinal intermediates. Although enzymatic phosphorylation is an effective approach to producing these nucleosides, its practical application is challenging due to the need for the expensive enzymes and coenzyme guanosine-5′-triphosphate (GTP). Here we prepared biocompatible calcium-based nanoflowers incorporated with cascade enzymes, uridine-cytidine kinase (UCK) and acetate kinase (ACK), for the production of nucleotides. The spatial distribution of these enzymes was optimized to maximize their catalytic performances. The most active nanoflowers (Ca₃(PO₄)₂& ACK)& UCK that display the rate-limiting enzyme UCK on the outer layer were used in a packed-bed reactor for continuous synthesis of 5′-UMP and 5′-CMP. The catalytic performance of the catalyst retained over 80% within 10 h, showing good operational stability.
