Research Publications (Food Safety)

The Food Safety Publications tracks research that is published across national and international peer-reviewed journals. Recent articles are available ahead of print and searchable by Journal, Article Title, and Category. The research publications are tracked across six categories: Bacterial Pathogens, Chemical Contaminants, Natural Toxins, Parasites, Produce Safety, and Viruses. Articles produced by USDA Grant Funding Agencies and FDA Grant Funding Agencies are also tracked.

  2. Delaying ripening using 1-MCP reveals chilling injury symptom development at the putative chilling threshold temperature for mature green banana

    • Wed, 09/14/2022 - 04:00
    • Frontiers in Plant Science
    • Storage at the putative chilling threshold temperature (CTT) to avoid chilling injury still limits postharvest handling of tropical fruit like banana in that ripening may occur at the CTT. To determine whether chilling injury (CI) symptoms would develop in mature green (MG) banana fruit if the CTT exposure was extended by inhibiting ethylene action and thus ripening, 1-methylcyclopropene (1-MCP) was applied.

    • Wed, 08/24/2022 - 04:00
    • Frontiers in Microbiology
    • Nitrogenase-dependent H2 production by photosynthetic bacteria, such as Rhodobacter capsulatus, has been extensively investigated. An important limitation to increase H2 production using genetic manipulation is the scarcity of high-throughput screening methods to detect possible overproducing mutants. Previously, we engineered R. capsulatus strains that emitted fluorescence in response to H2 and used them to identify mutations in the nitrogenase Fe protein leading to H2 overproduction.

  5. Determination of Singlet Oxygen Generated in Vegetable Oil Using Furfuryl Alcohol as Trapping Agent

    • Thu, 08/11/2022 - 04:00
    • Food Analytical Methods
    • Singlet oxygen (1O2), an initiator for photooxidation, is responsible for vegetable oil degradation. However, few details about the formation of 1O2 in vegetable oil are known due to the lack of a reliable method for its determination. In this study, a simple, reliable, and sensitive high-performance liquid chromatography (HPLC) method for indirect quantification of 1O2 generated in vegetable oil was developed. Furfuryl alcohol (FFA) was selected as a real-time “trap” for 1O2.

  6. MicroRNA candidate miRcand137 in apple is induced by Botryosphaeria dothidea for impairing host defense

    • Wed, 06/29/2022 - 04:00
    • Plant Physiology
    • MicroRNA (miRNA)-mediated gene silencing is a master gene regulatory pathway in plant–pathogen interactions. The differential accumulation of miRNAs among plant varieties alters the expression of target genes, affecting plant defense responses and causing resistance differences among varieties. Botryosphaeria dothidea is an important phytopathogenic fungus of apple (Malus domestica).

  7. Assessment of personal inhalation and skin exposures to polymeric methylene diphenyl diisocyanate during polyurethane fabric coating

    • Tue, 06/14/2022 - 04:00
    • Toxicology and Industrial Health
    • Methylene diphenyl diisocyanate (MDI) monomers and polymeric MDI (pMDI) are aromatic isocyanates widely used in the production of polyurethanes. These isocyanates can cause occupational asthma, hypersensitivity pneumonitis, as well as contact dermatitis. Skin exposure likely contributes toward initial sensitization but is challenging to monitor and quantitate.

    • Ethylene, produced endogenously by plants and their organs, can induce a wide array of physiological responses even at very low concentrations. Nevertheless, the role of ethylene in regulating blueberry (Vaccinium spp.) ripening and storability is still unclear although an increase in ethylene production has been observed in several studies during blueberry ripening.

    • Mon, 02/28/2022 - 06:00
    • Frontiers in Microbiology
    • One of the major mechanisms underlying plant growth-promoting rhizobacteria (PGPR) is the lowering of ethylene level in plants by deamination of 1-aminocyclopropane-1-carboxylic acid (ACC) in the environment. In the present study, using ACC as the sole nitrogen source, we screened seven ACC deaminase-producing bacterial strains from rhizosphere soils of tea plants. The strain with the highest ACC deaminase activity was identified as Serratia marcescens strain JW-CZ2.
