Postharvest Videos

Many of these videos are located on Youtube - As a result, we are in the process of compiling and storing on our web for access within Pakistan

Database of Existing Videos (from Dr Diane Barret, UC Davis)

Dr. Barrett reviewed numerous existing videos available on fruit and vegetable postharvest handling, preservation and quality evaluation and made a database which is summarized in this document: Fruit and Vegetable Videos. (It will open in Microsoft Excel). Below is a list of video titles in alphabetical order for each subject area, with a link to each video.

All of the videos are produced by government or public institutions except for the ones titled "Commercially Produced".
