BACKGROUND: Listeria monocytogenes is a widespread common contaminant in food production facilities during preparation, storage, and distribution, and minimally processed ready‐to‐eat products are considered at high risk of contamination by this bacterium. Increased antibiotic resistance has led researchers to search for plant‐based natural alternatives to control pathogenic microorganisms. Among ...
... BACKGROUND: Phytopathogenic microorganisms are the main cause of plant diseases, generating significant economic losses for the agricultural and food supply chain. Cherry tomatoes (Solanum lycopersicum var. cerasiforme) are very perishable plants and highly demanding in the use of pesticides; therefore, alternative solutions such as biosurfactants have aroused as a potent substituent. The main obj ...

The activity of F3H, the expression of gene encoding F3H and the antioxidant status in blueberries treated with ozone at a concentration of 1 ...
... BACKGROUND: 10‐Hydroxy‐cis‐12‐octadecenoic acid (10‐HOE, 10‐OH C18:1), an emerging functional fatty acid, has anti‐fungal and anti‐inflammatory effects. 10‐HOE is synthesized by bacterial 10‐linoleic acid hydratase (10‐LHT) with linoleic acid as the substate. However, the characterization of 10‐LHT and its targeted synthesis of 10‐HOE have been rarely reported. In this study, the recombinant 10‐LH ...
... BACKGROUND: Flavor is a key element affecting the popularity of French fries (FFs). When oil is heated, the changes in oil quality can affect the flavor of the food directly. RESULTS: The flavor of FFs showed three crucial stages: the break‐in (3.0% to 6.8% of total polar compounds (TPC)), optimum (7.0% to 19% of TPC), and degrading (above 19.5% of TPC) stages.

... BACKGROUND: Damage from cracking, russeting, and sunscalds causes significant yield losses in pomegranate worldwide and may result from stressful environmental conditions. Although foliar sprays with minerals or growth regulators could be an important orchard management, little is known on the effectiveness of glycine betaine, silicon (Si)‐based fertilizers or the response of cv. Wonderful to gibb ...
... BACKGROUND: The relatively inferior techno‐functionality of flaxseed protein/polysaccharide complexes, especially regarding emulsifying and antioxidant activities, has partially limited their implication in the health food system. The present study aimed to investigate the effects of an atmospheric pressure plasma jet (APPJ) on the physicochemical, structural and selected techno‐functional propert ...
... BACKGROUND: The recently developed Robusta coffee wilt disease resistant (CWD‐r) varieties in Uganda outperform the local landraces, both in yield and resilience. However, their uptake has been slow due to limited information on their cup worth. This study profiled the cup worth of the five most commonly grown CWD‐r across the Lake Victoria Crescent, Western Mid‐altitude farmland and Central Woode ...
... BACKGROUND: Vegetable oils are yearly produced in large amounts generating solid by‐products, the oilseed cake (OC). OCs are lignocellulosic materials that have been used for animal feed with some limitations due to high fibre content from the plant cell walls. Biotechnological processes can help to overcome these limitations and contribute to up‐grading such by‐products, enhancing their nutrition ...

... BACKGROUND: Ginger (Zingiber officinale Roscoe) is widely planted around the world. Owing to continuous planting, ginger is seriously affected by soilborne fungi, bacteria, and nematodes. Although preplant soil fumigation is an effective prevention strategy of soilborne diseases, individual fumigant and technology could not provide effective control of ginger soilborne disease. In our research, di ...
... BACKGROUND: Vegetable grafting has been increasingly evaluated to improve preharvest tolerance to biotic and abiotic stresses. However, very few studies have identified rootstock–scion combinations able to improve fruit shelf life and reduce the susceptibility to postharvest disorders. Herein, a purple eggplant scion (cv. Monarca) was grafted onto a cold‐tolerant hybrid Solanum rootstock (‘Java’) ...
... BACKGROUND: Ellagic acid (EA), a potent dietary antioxidant, has limited bioavailability owing to its rapid absorption in the stomach and small intestine, and EA is transformed to more bioavailable compounds – urolithins – in the colon. An encapsulation system that sustains the release of EA in the gastrointestinal system and delivers more EA into the colon could improve the oral bioavailability o ...
