I came across an article in the Huffington Post earlier about McDonald's french fries. The video attached to the short article on french fries is a little over 5 minutes long and somewhat informative on the pruction process. I attached the link at the bottom of this post if you would like to take a look. The video begins by showing where the french fry potatoes come from; yes, the fries are made ffrom real potatoes and no, the potatoes are not rectangular in shape (which came up in conversation during Professor Hsu's recent visit to class). The video shows potatoes being harvested in bulk by huge tractors. The word huge might not do a justice to the actual size of these tractors, these machines could harvest Farmer Chris' potatoes in probably under 5 minutes.
The production manager for the McDonald's Canadian french fry supply company, McCain, states during the video that they receive their potatoes daily from about 30 different local growers. Potatoes are shown being washed in a barrel washer similar to what we saw used on our first visit to the farm.
After the fries are peeled and cut, the natural sugars are removed by a blanching process. The reason this process is used is to limit color variation once the fries have been deep fried. A dextrose solution is then added so the color variation is limited when the fries reach the McDonald's restaurants. Another ingredient (unknown) is also added to the strips to prevent them from graying in color. The fact that the name of the "ingredient" wasn't stated made me question what it could possibly be. I assume it is a preservative because graying food usually means "no good."
This video was made for Canadian McDonald's. Where are the videos on the United States?
Other facts from this video:
All Canadian Mcdonald's restaurants use 100% vegetable oil to fry their fries.
According to the video, a basket of Mcdonald's fries (4 medium fries) only contains a spoonful of salt.
