  2. Proteomic and metabolomic studies on chilling injury in peach and nectarine

    • Tue, 10/04/2022 - 04:00
    • Frontiers in Plant Science
    • Peaches and nectarines are temperate climate stone fruits, which should be stored at 0°C to prevent the ripening of these climacteric fruits. However, if stored for too long or if stored at a higher temperature (4 or 5°C), they develop chilling injury. Chilling injury damage includes (1) dry, mealy, wooly (lack of juice) fruits, (2) hard-textured fruits with no juice (leatheriness), (3) flesh browning, and (4) flesh bleeding or internal reddening.

  3. Resveratrol improves postharvest quality of tomato fruists by enhancing the antioxidant defense system and inhibiting ethylene biosynthesis

    • Tue, 10/04/2022 - 04:00
    • Journal of Food Science and Technology
    • Resveratrol, the most widely studied phytoalexin, derived from the skin of grapes and other fruits. Evidence from numerous studies have confirmed its extensive bioactivities, such as antioxidation, anti-inflammatory and anticancer, as well as to promote antiaging effects in organisms. However, the effect of resveratrol on prolonging the postharvest storage of tomato fruits is still unknown.

    • Journal of Food Science and Technology
    • Development of fermented flavour during storage reduces acceptability of Shughri pear. Therefore, the current study was designed to investigate the combined effect of 1-Methylcyclopropene (1-MCP) and hypobaric treatment on stability of Shughri pear during 120 days of storage. Fruit were treated individually or combinedly with 25, 50, and 75 kilo pascal hypobaric treatments for 4 h and 1-MCP (0.3 μLL−1 and 0.6 μLL−1) for 24 h, whereas control received no treatment.

  7. The Use of Water in Animal Production, Slaughter, and Processing, Adopted 22 April 2021, Washington, DC

    • Fri, 09/23/2022 - 04:00
    • Water is an essential part of food animal processing, and current processing practices use large volumes of water. Due to climate change, the food industry’s access to clean and inexpensive water is increasingly a challenge. The Food Safety and Inspection Service (FSIS) seeks evaluation by the National Advisory Committee on Microbiological Criteria for Food (NACMCF) to facilitate the safe reuse of sources of water in order to reduce water consumption.

  9. 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.

    • Food Science and Technology International
    • Shiga toxin–producing Escherichia coli (STEC) has emerged as important enteric foodborne zoonotic pathogens of considerable public health significance worldwide. The aim of this study was to determine the prevalence of the top seven STEC serotypes and to identify these serotypes in samples of animal source foods and vegetables. A total of 294 samples including 84 meat samples, 135 milk and dairy product samples and 75 green leafy vegetable samples were tested.

    • Since the introduction of LED lamps a decade ago, the plant factory with artificial lighting (PFAL) has been expected to be a savior that overcomes the food crisis, brings food safety, and enhances environmental friendliness. Despite such high expectations, the diffusion of commercial crop production in PFALs has been slow. It has been said that the main reason for this is the huge initial investment required to construct PFALs.

    • Frontiers in Plant Science
    • Lipid phosphate phosphatases (LPPs) are a key enzyme in the production and degradation of phosphatidic acid (PA), which plays an important role in plant growth, development, stress resistance and plant hormone response. Thus far, little is known about the LPP family genes in kiwifruit (Actinidia spp.). According to this study, 7 members in the AcLPP family were identified from the whole genome of kiwifruit, the subcellular localization predictions were mainly on the plasma membrane.

    • 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.

    • 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.
