    (Frontiers, 2025-01-09) Mina, Zobabalo Progress; Kaseke, Tafadzwa; Fadiji, Tobi; Silue, Yardjouma; Fawole, Olaniyi Amos
    Introduction An effective and efficient drying method for preserving fresh carrots is essential in food processing. Combined drying represents a novel approach that addresses the shortcomings of conventional methods by balancing energy consumption, cost, and product quality. Methods This study evaluated the impact of combining oven drying (OD) with freeze-drying (FD) on drying behavior, energy requirements, costs, enzyme activity, and the physicochemical and sensory properties of dried carrots. Drying conditions included 36 hours of FD, OD, and combinations of OD and FD at 1 h of OD + 21 h of FD (OD1-FD21), 2 h of OD + 18 h of FD (OD2-FD18), 3 h of OD + 15 h of FD (OD3-FD15), and 9 h of OD. Results and discussion Compared to FD alone, the OD-FD combination reduced drying time by 39–50% and decreased energy consumption and costs by 40–56%. FD and OD-FD reduced polyphenol oxidase activity by 71–85% and peroxidase activity by 29–52% compared to OD alone. FD carrot slices retained significantly higher levels of β-carotene (11.67–25.96 mg/100 g DM), lycopene (9.91–21.85 mg/100 g DM), total phenolic content (7.12–10.24 mg GAE/100 g DM), and DPPH radical scavenging activity (16.44–19.38 mM AAE/100 g DM) than OD and OD-FD slices. OD-FD slices exhibited the highest levels of volatile compounds, including aldehydes, terpenes, esters, alcohols, ketones, and acids, indicating superior flavor preservation. Conclusion The OD2-FD18 combination emerged as the optimal method, significantly reducing energy consumption and costs while maintaining better β-carotene, total phenolic content, DPPH radical scavenging activity, and volatile compound profiles. This study highlights the potential of combined drying methods to enhance drying efficiency and product quality.

    Investigation of the horizontal collision damage behavior of fruit during transporting based on a new instrumented impactor
    (Elsevier, 2024-04-26) Wang, Minggang; Shi, Mingwei; Fadiji, Tobi; Li, Zhiguo; Song, Guoxiong
    Horizontal collisions between fruit and rigid walls are a common occurrence in postharvest packaging and transportation. To address this issue, a novel high-precision instrumented impactor was developed, comprising a high-speed imaging system, an ejection device, and a force sensor. Results showed that the impactor was able to effectively simulate the horizontal collision process between various small spherical fruits (such as cherry tomatoes, plums, sweet cherries, and winter jujubes) and packaging materials at three velocities: slow, medium, and high. Output parameters included the impact force and impact time of the fruit acting on each packaging material, as well as the displacement, displacement rate, impact energy, rebound energy, and absorption energy of the fruit. During the horizontal collision simulation, it was observed that the winter jujube exhibited the largest impact force and the shortest impact time among the four types of fruit tested. Conversely, the sweet cherry demonstrated the lowest proportion of damage area when colliding with the EPE board compared to the rigid board and foam board. This study presents a powerful tool for investigating the horizontal collision behaviour between fruit and rigid plates.

    Plants as an alternative to the use of chemicals for crop protection against biotic threats: trends and future perspectives
    (Springer , 2024-12) Aremu, Adeyemi Oladapo; Omogbene, Temitope Olorunyomi; Fadiji, Tobi; Lawal, Ibraheem Oduola; Opara, Umezuruike Linus; Fawole, Olaniyi Amos
    This review entails a critical appraisal on the potential of plants as alternatives to synthetic chemicals for crop protection, aligning with the global shift towards green-based approaches in agriculture. Utilising a defined set of inclusion and exclusion criteria, 235 papers were extracted from Scopus. These articles were analyzed to address specific research questions related to plant-based biocontrol methods. Approximately 25% of the literature was published in journals such as "Industrial Crops and Products", "Journal of Agricultural and Food Chemistry", "Pest Management Science", and "Frontiers in Microbiology". Thematic analysis identified core focus areas, including the chemical properties of antifungal agents, bioactive compounds, environmental protection, and the use of fungicides. Italy and China emerged as countries with the most represented authors, while China, India, and USA led in scientific production, corresponding authors' publications, and citation impact. We identified 91 plant species from 28 families, notably from the Lamiaceae, with strong potential as biocontrol agents. The most promising plants were Platycladus orientalis (L.) Franco, Mentha piperita L., Foeniculum vulgare L., Coriandrum sativum L., and Allium ascalonicium L. This study offers valuable insights and practical applications in the field of plant-based biocontrol, thereby underscoring the relevance and efficacy of green-based approaches in contemporary agricultural practices. There is an increasing scientific interest in sustainable crop protection strategies and the potential of plant-based biocontrol agents in addressing biotic stresses in crops. Overall, this review contributes to the understanding of plant-based biocontrol for crop protection, providing a foundation for further research and application in sustainable agriculture.

    The preservation of fresh-eating fruit within the supply chain is of paramount for maintaining freshness and minimizing resource waste. This article elucidates a comprehensive and integrated approach to fruit loss prevention and preservation techniques which collectively can substantially prolong the shelf life of fresh-eating fruits across various supply chain contexts. Here we show that the proposed solution emphasizes the development of real-time damage monitoring systems, innovative sensors for fruit freshness detection, and predictive methods for quality degradation and estimating shelf life. Additionally, we advocate for fundamental research to support the creation of smart, lightweight, sustainable, shockproof packaging systems. These packaging systems aim to utilize recyclable and biodegradable materials, contributing to environmental sustainability. In conclusion, this study establishes a scientific foundation for innovative solutions in the preservation and damage avoidance of fresh-eating fruits within the supply chain. By considering diverse factors and proposing a holistic approach, we anticipate substantial advancements in preserving the freshness of fruits.
