Phages can infect all bacterial genera on the planet leading to their abundance in ecosystems. While these bacterial viruses may represent a risk to industrial fermentations, they may also be valuable tools to control foodborne pathogens. Here we review these two sides of phage replication. As bacterial fermentations are constantly under threat of phage attacks, we will discuss phage diversity and industrial strategies employed to reduce their impact on food processing. Furthermore, we will explore the use of pathogen-infecting phages to reduce the risks associated with foodborne diseases.

This research investigates the impact of microwave power, processing time, and solid-to-solvent ratio on protein recovery from foxtail millet (Setaria italica), using an artificial neural network (ANN) and genetic algorithm (GA). The extracted protein and subsequent hydrolysates were also evaluated for their techno-functional, structural, and digestibility properties. The ANN model, trained with the Levenberg-Marquardt algorithm and optimized by a GA, identified optimal extraction conditions (960 W, 66.

Effects of high hydraulic pressure on the short-term retrogradation and digestive properties of Lonicern caerulea berry polyphenol-chestnut starch complexes.

Engineering Research Center of Chestnut Industry Technology of the Ministry of Education, College of Food Science & Technology, Hebei Normal University of Science and Technology, Qinhuangdao, Hebei 066004, China.

Both fresh and processed Chinese chestnuts are susceptible to retrograde hardening, affecting their texture, flavor, and shelf life because of their high starch content. To reduce the short-term retrogradation of chestnut starch during the food processing of chestnut-based products, a complex of Lonicern caerulea berry polyphenols (LCBP) and chestnut starch (CS) was prepared using high hydraulic pressure (HHP). The results showed that LCBP reduced the water separation rate, hardness, elasticity, and short-range order of retrograde CS under HHP and improved light transmission.

Porphyra haitanensis proteins (PHP) are natural proteins with various nutritional and biological values. This study was to analyze the composition, stability, and antioxidant activity of PHP before and after simulation gastrointestinal digestion (SGD). Caenorhabditis elegans was used as the model to investigate the functional activity and potential mechanisms of action of the PHP digestion products (PHPDP).

Catching, carrying, and loading of broilers before transport to the slaughterhouse causes stress. In this study three catching methods (two manual (inverted, upright) and one mechanical) were compared using a cost-benefit analysis of animal welfare, ergonomics and economic analysis. Depopulation of approximately 5,000 broilers per catching method per flock (upright vs.

This research developed a magnetic relaxation switching (MRS) biosensor based on hydrogel sol-gel transition and the CRISPR/Cas12a system (MRS-CRISPR) to detect Salmonella. Herein, the alkaline phosphatase (ALP) labeled with streptavidin was captured by the biotin-modified DNA on magnetic nanoparticles (MNPs) surface, which generated an acidic environment via enzymatic reaction to release Ca and induced the transformation of alginate sol to hydrogels. In contrast, Salmonella activated the trans-cleavage activity of the CRISPR/Cas12a system, interrupting the capture of ALP and the subsequent sol-gel transition.
