Dehydrating meals is taken into account certainly one of our oldest—if not oldest—methodology for preserving meals. For so long as our species has been gathering, foraging, and throwing spears at wild beasts, now we have been extending the expiration date on our meals via varied types of dehydration.
The idea of dehydrating meals is easy: take away moisture to stop the expansion of micro organism, fungus, and yeast. This may be completed via varied strategies utilizing totally different tools, although some choices are higher than others. The advantages of dehydrating meals far outweigh the negatives. You possibly can dehydrate most non- and low-fat meals, together with meat and contemporary fruit and veggies.
Advantages of Dehydrating Meals
Whereas dehydrating meals extends its shelf life, the method additionally supplies many different advantages. Some examples are under.
- Reduces likelihood of micro organism and mould progress. (A part of extending shelf life.)
- Maintains most of dietary worth regardless of lack of moisture. Nonetheless, some vitamins like B nutritional vitamins, vitamin C, and beta carotene are misplaced when moisture is misplaced, so chances are you’ll must compensate for these nutritional vitamins relying in your wants.

This precept of dehydration can be the rationale each deer hunter has extra buddies are looking season, all asking for one factor: jerky, please.

Negatives of Dehydrating Meals
There aren’t many, and all could be overcome, if an individual is conscious and acts accordingly.

Strategies and Gear for Dehydrating Meals

Solar and air drying don’t require tools and are probably one of many oldest methods to dehydrate meals but in addition introduce a pair uncontrollable elements for some climates: temperature and humidity degree. The perfect temperature for dehydrating meals will differ by meals, however, as a common rule, the humidity degree must be saved between 12 and 18 %, a situation that could be onerous for some in sure areas to depend on.
For the above causes, varied tools can be utilized to extra reliably dehydrate meals.
Photo voltaic Drying
Powered by the solar, these operate through the use of solar’s energy to warmth air, which then circulates across the meals to dry it out. This gear is extra environmentally pleasant, however at the price of {dollars} and probably reliability in comparison with different choices.
Oven
A convection oven, in precept, isn’t a lot totally different than an electrical dehydrator, assuming it circulates heats evenly. Nonetheless, most ovens received’t go as low by way of temperature in comparison with a dehydrator. Some meals require temps decrease than an oven present; in any other case you find yourself hardening the meals and ruining its texture earlier than it ever correctly dehydrates. However for jerky, or something that requires 140 F or increased, a very good convection oven—assuming its inside temperature gauge capabilities correctly—is an possibility. Typical ovens aren’t an incredible possibility for something, however are extra reasonably priced.
Smoker / Pellet Grill
Most people who smoke and pellet grills received’t go under 160 F since that is thought-about the bottom “secure” temperature for cooking/smoking meat. However a smoker or pellet grill, similar as a dependable convection oven, will flow into warmth and air evenly to dehydrate meals that may work within the 160 F vary over a protracted time period.
Electrical dehydrator
That is, in my view and expertise, probably the most dependable methodology. Costs will differ, however you’ll be able to often discover a high quality one, when on sale, for $100 or so. I’ve utilizing MEAT!’s 6-Tray for a number of years now and it capabilities very nicely. A superb dehydrator will go as little as 90 F and as excessive as 170 F whereas offering constant 360-degree airflow. That is one of the few items of kit I really feel belongs in each kitchen.
Basic Greatest Practices for Dehydrating Meals

As talked about earlier, most non- or low-fat meals are honest sport. Meals with a notable fats content material—corresponding to eggs, avocados, olives, something dairy—current food-safety points, as fats, by way of meals preservation, will oxidize and trigger spoilage.
Dimension
When dehydrating meals, you need to hold slices or items as uniform as potential—slices probably no thicker than 1/4-inch. As a result of some meals can take upwards of 48 hours to dehydrate, the slightest distinction in measurement over a protracted time period may imply one piece will get dehydrated appropriately whereas one other doesn’t (whether or not too dry or not dry sufficient).
Blanching or steaming
Blanching (dipping meals in boiling water then shortly pulling and cooling in an ice bathtub or beneath chilly operating water) can assist greens retain their colour and cut back dehydration time. For any vegetable you wouldn’t eat uncooked or which are notably robust (e.g., carrots or potatoes), it helps to first blanch; in any other case the dehydration time will probably be probably days. With fruits corresponding to berries or cherries, a blanch will crack the pores and skin and promote faster and extra thorough dehydration.
Ascorbic or citric acid
These each are an possibility to stop the browning of some fruits corresponding to apple slices. I personally prefer to squeeze contemporary lemon juice overtop my apple slices earlier than dehydrating.
Basic Greatest Temps and Occasions for Dehydrating Meals
It would differ significantly by kind of meals and the way you’re prepping the meals. For instance, sliced apples and blueberries would require an identical temperature however, although each fruits, will differ considerably by way of time wanted. The “doneness” check may even differ by particular person meals merchandise, chances are you’ll must analysis a bit extra other than the information right here.

Expiration Date
Vacuum sealing—whether or not by way of baggage or jars—removes air and can assist protect meals. The tighter the seal, the higher. Desiccant packets assist in eradicating moisture, whereas oxygen-absorber packets take away oxygen. Each are an possibility to increase shelf life, as the mixture of oxygen, moisture, and warmth result in spoilage. To scale back results of warmth, retailer in a cool, dry place. For some meals with an air-tight seal, the shelf life is upwards of 30 years in response to some sources. Nonetheless, under are some common timelines based mostly on common finest practices for dehydrating meals at house.
Meals | Shelf life |
Herbs | 1-2 years |
Greens | 6 months |
Beans and lentils | 1-2 years |
Mushrooms | 2-4 months |
Fruit | 6-12 months |
