With the knowledge that retail pork products may be contaminated with methicillin-resistant Staphylococcus aureus (MRSA), the risk of consumers contracting a MRSA infection or foodborne illness from processed meats, especially bacon, is uncertain. Therefore, a study was designed to investigate the survival of MRSA during heat treatment of slab bacon at a commercial process and during cooking of sliced bacon at the consumer level. Fresh pork bellies were injected with a curing solution, inoculated, and heat treated to an internal temperature of 52°C. Three commercial brands of sliced bacon with similar "sell by" dates and fat-to-lean ratios were also inoculated and cooked at a temperature of 177°C for 0, 2, and 5 min on each side. Heat-treated slab bacon showed a log reduction of 1.89, which was significant (P < 0.05) compared with an uncooked inoculated control. Cooked sliced bacon had a reduction of viable MRSA cells of >6.5 log CFU/cm(2), and there was not a significant brand interaction (P > 0.05).

Cooking loss estimation of semispinalis capitis muscle of pork butt using a deep neural network on hyperspectral data.

This study evaluated the performance of a deep-learning-based model that predicted cooking loss in the semispinalis capitis (SC) muscle of pork butts using hyperspectral images captured 24 h postmortem. To overcome low-scale samples, 70 pork butts were used with pixel-based data augmentation. Principal component regression (PCR) and partial least squares regression (PLSR) models for predicting cooking loss in SC muscle showed higher R values with multiplicative signal correction, while the first derivative resulted in a lower root mean square error (RMSE).

Institute for Advanced Biosciences, Keio University, Tsuruoka, Japan.
The increasing demand for protein-rich, plant-based foods has driven the development of meat analogs that closely mimic the texture and mouthfeel of animal meat. While plant-based fibrils and electrospun silk fibroin fibers have been explored for texture enhancement and scaffolding in both meat analogs and cell-based meats, the use of wet-spun fibroin protein fibers as a food ingredient remains underexplored. This study investigates the potential of wet-spun recombinant fibroin fibers to enhance the textural properties of meat analogs.

The authenticity of halal meat is a global issue because pork adulteration occurs. Certain religions, such as Islam and Judaism, prohibit the use of pork in food products. The purpose of this study was to evaluate the volume of trypsin with 10, 50 and 100 μL (20 μg/100 μL) and the digestion time from overnight to 30-120 min to establish a fast and straightforward procedure on proteomic analysis for halal authentication of meat and meat products.

This study investigates quality changes occurred in sliced pork belly with different fat content during refrigerated storage, and the potential of spectral imaging technology in predicting quality properties. Pork bellies with different fat levels (low 'LF', medium 'MF' and high 'HF') were selected from slaughtering houses and directly transferred to the laboratory. The sliced bellies were packed in modified atmosphere packages with high oxygen levels (80 %) and the essential visual and olfactory characteristics, microbiological load, pH, lipid oxidation and colour values were assessed throughout 20 days of refrigerated storage.

Dry-cured ham is a traditional Mediterranean meat product consumed throughout the world. This product is very variable in terms of composition and consumer's acceptability is influenced by different factors, among others, visual intramuscular fat and its distribution across the slice, also known as marbling. On-line inter and intramuscular fat evaluation and marbling assessment is of interest for classification purposes at the industry.
