“…Many sources on postharvest loss date back to the seventies and eighties (Pariser, 1987;Greeley, 1991), and tended to focus on loss in staple crops rather than perishable fruit and vegetable crops based on the notion then that the reduction of postharvest loss for staples could contribute to reducing world hunger. The current interest for postharvest research in perishable crops may be associated with a growing concern for food safety.…”

This study provides an overview of the postharvest loss situation of selected vegetable crops as perceived by the various supply chain actors in Vietnam, Cambodia and Laos. It investigates the volume and value of vegetable losses upstream along the supply chain, and identifies the main reasons and the preventive measures undertaken at each stage in the supply chain to abate postharvest losses. Loss estimates are compared by supply chain actor, country and crop. This study finds that the average loss of the selected vegetables is about 17%, and that farmers are the most vulnerable group compared to middlemen and retailers who both have more control on product prices. It recommends developing measures to contain disease problems for farmers, and improving marketing efficiency through standardisation of product quality for middlemen and retailers.

“…Pariser (1987) cited the minimal overall post harvest fish losses in developing countries as 20% of total production. Each year in the absence of proper handling, processing and marketing infrastructure, large quantities of fish are lost for consumption (Shimang, 1992).…”

This study utilised face to face survey method through semi structured interview schedule for gathering information regarding the quantity of seafood raw materials procured and the associated waste generation pattern, waste management issues and ultimately the impact excreted by the waste produced to the local community, in India's one of the major seafood processing zone, the Cochin Corporation (CC), in the state of Kerala. In the study area, large quantities of seafood solid waste is left as unutilised, and are managed largely by the private sector for disposal. The unregulated disposal of seafood solid and liquid waste has created environmental and social ill effects in the area. It is hoped that this study would prove as a tool for future waste management planning and by-product valorisation decisions by the seafood industry as well as the authorities.

“…In the near future, the demand for dried products will have an upward trend to meet the needs of the growing population, which will touch 9.7 billion by 2050 . Moving further, the strategy of minimizing food and agri-product wastage through the use of sustainable drying technologies becomes necessary as it is known that around 10–20% of postharvest losses take place due to the lack of affordable and inaccessible technologies . The losses can reach as high as 50% in highly perishable horticulture products, such as tomatoes, leafy vegetables, and fruits (mango, sapota, etc.…”

The current article introduces a new tool to model drying kinetics. The perspective described here involves application of regimes originally used for heterogeneous reactions to quantify the reaction rate against the diffusional transfer of reactants. This method helps to determine the controlling steps in the falling and constant rate periods of drying and can be used as a base for advanced mathematical models. The proposed method can be used for solid/semisolid materials of varying dimensions. It addresses the research gap of the current unavailability of a universal technique to describe drying kinetics. The effect of parameters such as temperature, humidity, and the dominant mode of drying has been discussed with the help of a sample material (tomato). The effect of using different regimes for the variation of relative excess activation energy against the moisture content is also discussed. This approach showcases the "internal" character of the material and the kinetic model can be applied to different drying processes. The conditions under which transition between regimes may occur are also discussed and elaborated in terms of dimensionless numbers, such as the Hatta number and the Biot number.
