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%, out-performing 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.

Human intestinal gut microbiota harbors complex and diverse microbes that play an important role in maintaining the homeostasis of the intestinal microenvironment in humans.

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.

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.

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-infrared 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.

Single-use bioreactors (SUB) have made a significant impact on the field of bioprocessing, becoming increasingly popular for biomolecule synthesis due to their many advantages, such as minimizing contamination risks and streamlining processes. Extensive research has been conducted on the hydrodynamic conditions within single-use bioreactors, with a focus on parameters like mixing time, oxygen transfer rate, and stress levels to improve cell cultivation procedures. Several studies have demonstrated that SUB can effectively nurture various cell types, including those that generate monoclonal antibodies, yielding outcomes similar to conventional bioreactor systems, thus highlighting their adaptability and effectiveness in biomolecule processing. SUB equipped with wave mechanisms have shown to display comparable metabolic behaviors and fermentation consistency to conventional bioreactors, confirming their dependability in supporting fungal growth and metabolite generation. Mechanical stirring for agitation leads to high shear forces alongside enhanced monitoring and control, influencing microbial physiology and macro-morphologies. This underscores the importance of operational factors such as rocking speed, rocking angle, and gas flow rate. Overall, the integration of single-use bioreactors in biomolecule synthesis is expected to expand, driven by the need for increased yields and cost-effective manufacturing solutions.

This study investigates the expanding domain of functional beverages crafted from plant-based milk alternatives. In this study, a total of eight different fermented drinks fortified with beneficial Chlorella sp. and probiotics including Lactobacillus rhamnosus (NCIM 5775) and Saccharomyces cerevisiae (Brewer’s yeast) drinks were developed using barnyard millet as the base ingredient due to its rich protein and high-fibre content in comparison with the other millets in the market. Results revealed that the protein content increases by 2% upon the addition of Chlorella sp., among bacterial samples, with Lactobacillus rhamnosus fermented Unflavoured drink (LRFFD) > Lactobacillus rhamnosus fermented flavoured drink > Lactobacillus rhamnosus fermented with Chlorella sp. > LRFM, and among yeast samples, with Saccharomyces cerevisiae fermented Unflavoured drink (SCFUFD) > Saccharomyces cerevisiae fermented with Chlorella sp. > Saccharomyces cerevisiae fermented flavoured drink (SCFFD) > SCFRM, indicating higher protein content than in typical fermented drink. Fat content was notably low across all samples. Ash and fibre content ranged from 0.23 to 0.27 g and 0.22 to 0.35 g, respectively, for both bacterial and yeast fermented drink. Millet is generally considered a carbohydrate-rich grain. When fermented, some of the carbohydrates may be broken down by the fermentation process. So, the carbohydrate content was low in fermented millet drink when compared to the nonfermented drink. Energy values varied, with LRFFD and SCFFD containing the highest energy due to incorporation of Chlorella sp. and chocolate flavour. Both LAB and yeast-fermented drinks demonstrated effective antioxidant activity, with higher total phenolic content, except for non-Chlorella sp. beverages. GC-MS analysis identified constituents like hexadecenoic acid and hydroxy methyl furfural (HMF) with anticarcinogenic and anti-inflammatory properties. Additionally, these samples exhibited elevated antimicrobial activity against test strains. Sensory analysis indicated a preference of SCFFD and LRFFD sample for its good taste as it contains chocolate flavour and the overall acceptability of bacterial fermented beverage was higher compared to the yeast fermented drinks. Therefore, a fermented millet beverage was successfully obtained by the coculture of LAB and Saccharomyces cerevisiae incorporated with Chlorella sp. could increase the product’s functional properties.
