It has been widely recognized that one of the biggest challenges in the agricultural production value chain is the issue of postharvest handling and processing of agricultural products. It is estimated that 25-30% of global food produced is lost during the postharvest value chain, mainly due to fallible chain management (especially during sorting, bulk storage, packaging, and transportation), spoilage, and pest infestation. Several systems and processes have been developed to reduce the postharvest losses of agricultural products during postharvest cooling, transport, and storage operations. For example, the use of "cold " handling and storage systems to prevent perishable food losses; the thermal and non-thermal processing of harvested agricultural products to reduce spoilage and enhance shelf-life; and the drying of agricultural products to also reduce spoilage, increase shelf-life, and reduce the bulk weight of products during transportation. Nevertheless, most of the systems developed are yet to be fully commercialized. This is a result of an inadequate understanding of the complex nature of different agricultural products, understanding of the physics behind different phenomena that occur during different postharvest processes (e.g drying, cooling...etc), and the upscaling of developed process systems. For instance, a lot of strongly coupled phenomena take place during cooling and dehydration of agricultural products, including (1) heat and mass transport inside the material, (2) their exchange with the airflow in the environment, (3) microstructural damages, (4) shrinkage, and (5) reduction of nutritional density. These coupled physiochemical processes make it challenging to understand and optimize the relation between process parameters and final product properties and structure. Therefore, the successful design of a cooling, packaging, storage, transport and drying processes of fresh food requires linking materials science, fluid dynamics, mechanical deformation, food chemistry, and process control.
This Special Issue on “ Advances in Postharvest Process Systems” focusses on the latest research and development in this area. We target specifically the development and application of novel and sustainable postharvest process technologies as well as how modeling can help advance innovative processes or technologies by providing insight for process optimization. Contributions to cover materials such as meats, fruits and vegetables, grains, foods, and fibres are most welcome. In addition, review papers providing critical overviews of state-of-the-art developments on postharvest engineering research are welcomed. Topics include, but are not limited to:
- Advances in drying technologies and modeling thereof (multiscale, multiphysics, multiphase);
- Advances in food system and postharvest value chain management and modeling thereof (multiscale, multiphysics, multiphase);
- Advances in packaging technologies
- Emerging cold chain processing technologies and modeling thereof
- Emerging storage technologies and modeling thereof
- Emerging transport technologies and modeling thereof
- New approaches on improving models and model accuracy (e.g. coupling of quality models, advanced material property models)
- Model validation at different scales (e.g micro scales, macro scales), using advanced monitoring methods
- Product separation
- Intelligent process control using computational engineering
- Scale-up studies from laboratory to process plant level (simulation and experimental driven)
- Application of digital twins in cold-chain, storage, and drying systems
- Environmental impact assessment.
We aim to have a rapid review process to provide a channel for the timely dissemination of fresh, and impactful manuscripts. Apart from providing research on recent trends in postharvest engineering, this research series is envisioned to catalyzed simulation research on different unit operations in the postharvest value chain to better understand process modeling and optimization towards a sustainable system
