Letter Re: Question on Dried Foods Versus Dehydrated Storage Foods

Is there any difference between dried food and dehydrated food, and if there is, what is the difference? – G.P.

JWR Replies: I’m glad that you asked that, because it is often a point of confusion. Although semantically they mean the same thing, the difference is that “dehydrated” storage foods typically are dried to a greater extent than typical dried foods–such as the raisins and other dried fruits that are sold at your local grocery store. However, due to their lower moisture content and because they are usually sold in sealed, nitrogen-packed, cans makes them store for several years instead of just a few months. Also, don’t forget that “dehydrated” is far different than freeze drying, which can result in even longer storage life, particularly if canned.
