Virtual Experiments in Food Processing

Virtual experiments allow students to conduct experiments using a computer or a mobile device. These experiments may be used as stand alone or they may augment hands-on laboratory experience.

Select a virtual experiment from the other column and a new window will open in your browser where you may conduct the selected experiment by changing input parameters.

Instructions for saving data on a spreadsheet for further analysis

To export results data from the virtual lab:
1) click the "Export Data" button on the "Virtual Experiment" webpage.
2) Save the file.
a) If using Internet Explorer, a new webpage will pop up. Save the webpage as a text file
by choosing "Text Files" in the "Save as type" dropdown list (A .csv file name extension
shouldn't be added here. By doing so, IE will save a html file instead).
b) If using Firefox, a new webpage will show up. Choose "Text Files" in the "Save as type"
dropdown list, and save the webpage as a ".csv" file (.csv suffix is okay here).
c) If using Google Chrome, a file with the name of "download" will be automatically downloaded.
d) If using Safari, a new window will pop up. Save the webpage as a ".csv" file.

To import data into Excel:
1) Locate the downloaded text file, and add a ".csv" extension to the file name if it's not already there.
2) Open the csv file using Excel directly.

This data transfer feature is not available if you conduct virtual experiments using an iPad or iPhone. Please allow sufficient time (around 10-20 s) when you use mobile devices to view the resulting plots.

Virtual Experiments in Food Processing - an eBook with software

Using pedagogical principles, a set of 23 virtual experiments were developed and published in a book that contains all required simulations. More information regarding the book and how to order it is described here.
