Peracetic acid mixture (PAHP), which is a combination of peracetic acid and hydrogen peroxide, has been approved as an antimicrobial for use in poultry chillers. To validate its effectiveness, 85 ppm of PAHP was compared with the 30-ppm chlorine treatment in a commercial setting. In this trial, 100 carcasses were sampled for Salmonella and Campylobacter spp. prior to chilling and 100 carcasses were sampled after chilling. In all, 400 carcasses were sampled using 85 ppm of PAHP in the chiller and 400 carcasses were sampled using the chlorine treatment. PAHP at 85 ppm reduced Salmonella-positive carcasses by 92% exiting the chiller, whereas treatment with 30 ppm of chlorine reduced Salmonella by 57%. Additionally, PAHP reduced Campylobacter species-positive carcasses exiting the chiller by 43% while chlorine resulted in a 13% reduction. These results suggest that peracetic acid in combination with hydrogen peroxide may be an effective antimicrobial in poultry chiller applications.

Traditional meat preservation techniques such as smoking, drying, and salting have various shortcomings and limitations in effectively reducing microbial loads and maintaining meat quality. Consequently, chemical compounds have gained attention as promising alternatives for decontamination, offering the potential to extend shelf life and minimize physical, chemical, and sensory changes in meat. Chlorine-based compounds, trisodium phosphate, organic acids, bacteriocins, lactoferrin, and peracetic acid are technologies of recent industrial applications that inhibit spoilage and pathogenic microorganisms in meat.

We evaluated the antimicrobial performance of sodium hypochlorite (NaOCl) and peracetic acid (PAA) during washing of baby spinach in water of varying levels of organic load, as measured by its chemical oxygen demand (COD). Escherichia coli TVS353 was spot inoculated onto one unwashed leaf. Sanitizers were added into water with preadjusted COD (300 or 2500 ppm) to achieve concentrations from 20 to 80 ppm.

OH-mediated advanced oxidation processes (AOPs) are widely used in wastewater treatment and drinking water purification. Recently, an increasing number of studies have indicated that common inorganic nitrogen ions can efficiently generate •OH under UV irradiation, demonstrating strong performance in the degradation of various contaminants. Conversely, the presence of inorganic nitrogen ions in UV or other oxidation processes dramatically increases the yield of toxic nitro (so)-aromatic products and the formation potential of nitrogenous disinfection by-products with high genotoxicity and cytotoxicity.

Recently, transparent wood (TW) has been considered for many energy-efficient building products, such as windows and decorations. However, the existing TW still faces issues with size and thickness, as well as problems with functional fillers affecting the optical and mechanical properties of TW, which limits its wide application in the window products. In this study, a wood composite material (WCM) with good optical, mechanical, and thermal insulation and UV-shielding properties was prepared by using delignified wood (DW), methyl methacrylate (MMA), and 4-vinylphenylboric acid (VPBA).

Peracetic acid (PAA) is an emerging disinfectant known to be highly effective against various microorganisms. However, the capability of PAA to eliminate spores under different conditions and its application in liquid and gaseous forms remain unclear. Here, we aimed to develop a stabilized single-composite PAA and evaluate its disinfection efficacy in both liquid and gaseous form against suspended or surface-coated spores under varying temperature and humidity conditions.
