Article Abstract
Meat products contain valuable nutrients that are important for human health and development but are also highly susceptible to colonization by microorganisms. This can lead to spoilage and serious foodborne illnesses. Natural antimicrobial peptides, produced by many organisms as part of their innate immune system to fight microbial infections, have great potential as food preservatives. In this study, we explored the effect of ternary antimicrobial random peptide mixtures (RPMs) on food spoilage bacteria in minced turkey meat. Amendment of RPMs to meat led to significant reductions in bacterial abundance in experimental tests, and RPMs worked synergistically with nitrite to reduce bacterial loads. Using high-throughput 16S ribosomal RNA gene amplicon sequencing, we characterized the effect of RPMs and nitrite on meat microbial community structure before and during incubation under refrigerated conditions. Our findings reveal strong antimicrobial activity for RPMs against spoilage bacteria in meat, including Listeria monocytogenes and Pseudomonas putida. These results demonstrate the potential of RPMs as a safer preservative for reducing spoilage in meat and other food products.
This study aimed to utilize UV-C technology to improve the functional properties of starch-based films for minced meat packaging. Starch film solutions were exposed to UV-C light for varying durations (15, 30, 60, and 120 min). Results revealed significant reductions in the water solubility, swelling degree, and elongation at break values of films following treatment (P < 0.

There is considerable interest in the use of essential oils for food preservation, but their effect on the aroma profile of a product is poorly understood. This study investigated the effect of thyme essential oil (EO) addition at increasing concentrations (0.005, 0.
* The measurements utilized both semileptonic and hadronic decays of top quarks, along with events focused on single top quark production in the electroweak t channel.
* The combined result for the top quark mass is 172.52 GeV, with a reduced total uncertainty of 0.33 GeV, showcasing an improvement of 31% over previous measurements.
While there are data regarding the glycaemic index (GI) and glycaemic load (GL) of many foods in the literature, the values for packaged vegan analogue foods have not been previously published, although processed vegan foods usually contain more carbohydrates than their animal-based counterparts. This study was carried out to determine the GI and GL values of a selection of packaged vegan foods popular in Türkiye. To determine the GI and GL of test foods, 12 healthy volunteer females participated in the study.

This study investigated the functional properties of freeze-dried encapsulated Oliveria decumbens Vent. (OEO) and basil (BEO) essential oils (EOs) in maltodextrin/gum arabic coating solution (1:1). Nanoencapsulated EOs were evaluated in terms of size, polydispersity, encapsulation efficiency, morphology, antioxidant, and antibacterial activities (AOA and ABA), and sensory characteristics in vitro compared to the control.
