Cold atmospheric plasma, featured as a non-thermal food processing technology has gained prominent attention for its practical application. The demand for chilled chicken has increased rapidly due to its nutritious value. However, chilled chicken often suffers from a short shelf life due to its susceptibility to spoilage. In this study, air- and nitrogen plasma were applied to investigate microbial inactivation effects and shelf-life extension of chilled chicken. Meanwhile, the microbial diversity of chicken breasts after air and nitrogen-CAP treatment and at the end of shelf-life was analyzed. Results illustrated that the inactivation effects of air plasma were more potent than that of nitrogen plasma, while nitrogen plasma could better maintain the sensory properties. Also, further investigation illustrated that air- and nitrogen-CAP could change the microbial community significantly. Both treatment time and working gases were essential experimental parameters that affected the microbial community composition.

Background: Ozone (O) is a promising alternative antibacterial agent that has recently been used in meat processing. The understanding of the appropriate functional settings of O for addressing food safety problems is still insufficient.
Aim: The aim of this study was, therefore, to investigate the effects of exposure to O on the bacteriological quality of retail meat inoculated with at refrigeration temperatures.

Article Synopsis
- Researchers are focusing on improving broiler chickens for better meat production through breeding, particularly using the EGR1 gene as a target.
- EGR1 shows higher expression in chicken breast tissues with lower muscle content and is involved in muscle growth by affecting myoblast behavior.
- The study identified specific EGR1 gene variations linked to various slaughter traits in the Jiangfeng M3 lineage partridge chickens, helping to enhance breeding strategies.
Rapid detection of poultry meat quality using S-band to KU-band radio-frequency waves combined with machine learning-A proof of concept.

Rapid changes in consumer preferences for high-quality animal-based protein have driven the poultry industry to identify non-invasive, in-line processing technologies for rapid detection of muscle meat quality defects. At production plants, technologies like radio-frequency waves (RF waves) can identify and separate myopathy-conditioned meat, reducing misclassification errors due to human fatigue and inexperience. Previous studies have shown that advanced diagnostic tools combined with complex data analytics, such as support vector machines (SVMs) and backpropagation neural networks (BPNNs), can classify chicken breast myopathies post-deboning.

Quality deterioration caused by microorganisms is a crucial problem in food industry. Herein, to enhance the antibacterial effect and extend the storage life of chilled chicken, a gelatin/chitosan (GC)-based "sandwich" nanofiber film was prepared by sandwiching GP2 (gelatin nanofibers loaded with 2 % (v/v) perillaldehyde) between two layers of GC nanofibers. The diameter of GP nanofibers was positively correlated with perillaldehyde concentration.
