I am a regular on The Survival Podcast as an expert on health, finance, and life simplification. Below is the transcript of my answer to a listener question on healthy food dehydration in humid climates.
Food Dehydration Question
How do you keep dehydrated food preserved in a humid climate?
In humid climates like the Pacific Northwest, my Excalibur dehydrated fruits and vegetables begin re-hydrating after only a few weeks. I usually store dehydrated food in quart or pint jars with screw-on lids. How can I preserve them longer? maybe vacuum sealing the jars? Thanks!Dan

Gary Collins (Answer): Hey, everyone. This is Gary Collins, creator of www.thesimplelifenow.com. A great question for survivalists and preppers is dehydrating food and how to make it last longer, especially if you live in a more humid climate.
There are a couple of different ways. There’s not a whole lot of options here. That’s just the way nature works. But remove the air, and the more air you remove or removing almost all the air will make the dehydrated food last longer.
Dan asks if he can vacuum seal. Absolutely. You can do the jars, or what a lot of people do is they actually go get, professional-grade, some consumer‑grade, vacuum sealers that come with the bags and does it all for you. Those work excellent, and they do prolong your dehydrated foods, but the downside is that you end up storing them in plastic.
I think those are two of the best ways. You can boil the food and then dehydrate it, but it takes a long time, and it changes the taste and nutritional profile, so I’m not a big fan of that.
Also what you might try is actually giving it two rounds of dehydration and see if that helps. If you have a lot of moisture in the air, your dehydrator is not going to dehydrate the food as it would normally. You might want to put it in for another half-round or full round and see if that helps.
I hope that answers your question. If you have any comments, hit it in the comments section. Thanks.
