Journal ArticleDOI

Mechanical damage of fresh produce in postharvest transportation: Current status and future prospects

TL;DR: In this article , a comprehensive discussion on the effects of packing unit type and surface of packaging material, location of the package on the vehicle, and height of package in a stack on the vibration level is presented.
Journal ArticleDOI

Effect of box materials on the distribution of 1-MCP gas during cold storage: A CFD study

TL;DR: In this paper, the influence of box materials and plastic cover on the distribution of 1-Methylcyclopropene (1-MCP) in cold storage was studied using validated CFD models Reynolds Average Navier-Stokes equations with the SST k-ω turbulence model were used to calculate the airflow Diffusion, convection and adsorption of 1MCP were modeled to obtain 3D spatial and temporal distributions of 1mCP inside a storage container, boxes and fruit.
Journal ArticleDOI

Bioactive compounds and quality attributes of pomegranate arils (Punica granatum L.) processed after long-term storage

TL;DR: In this article, the effects of packaging on physicochemical properties, bioactive components (anthocyanins, ascorbic acid and b-carotene) and shelf life of pomegranate arils (cvs. Arakta, Bahgwa and Ruby) obtained from fruit stored for a long-term (between 10 and 14 weeks).
Journal ArticleDOI

Experimental and Numerical Investigation of Airflow Inside Refrigerated Shipping Containers

TL;DR: In this article, the authors investigated the airflow distribution inside two types of refrigerated shipping containers (T-bar floor and flat floor) used for transporting fresh fruit handling were investigated.
Journal ArticleDOI

Effect of Carrier Agents on the Physicochemical and Technofunctional Properties and Antioxidant Capacity of Freeze-Dried Pomegranate Juice (Punica granatum) Powder

TL;DR: Overall, maltodextrin reflected the most suitable carrier agent to produce PJP, which indicates better reconstitution properties and good stability during storage and a lower degree of caking.
