Dehydrating food: A thrifty and timeless preservation method

The art of dehydrating food is as ancient as civilization itself, with early societies drying fruits and plants under the sun to prevent spoilage. Today, modern dehydrators offer precision and convenience, allowing home cooks to preserve food efficiently while retaining nutrients and flavour.

Preserving food while saving money

Food waste is a costly problem. American households discard nearly 32 percent of their purchased food annually – a costly loss valued at $240 billion, according to a 20202 study published in the American Journal of Agricultural Economics.

Dehydration presents an affordable and healthy solution to this problem, using minimal electricity compared to freezing and requiring no added preservatives. Dehydrated fruits and vegetables, when stored properly, can last years and serve as nutritious emergency food when disaster strikes.

Centuries ago, Indigenous cultures sun-dried berries into lightweight travel rations to maximize their food supply. The 20th century saw innovations like electric dehydrators, making this age-old food preservation method accessible indoors. Today, vacuum-sealing can further extend the shelf life of dehydrated foods.

A shift toward self-sufficiency – fuelled partly by pandemic-era shortages – has revived interest in food preservation methods. Sales of dehydrators and canning supplies have surged as people began to seek resilience against supply chain disruptions.

People who have abundant supplies can reduce waste by dehydrating foods that spoil easily. For example, if you have overripe bananas, peel them and dehydrate them into chewy snacks instead of throwing them in the trash. Store the dehydrated bananas in quart-sized mason jars with vacuum-sealed lids for longer shelf life.

The same technique can be applied to surplus tomatoes, which can be dried and then ground into powder for soups and sauces.

To preserve fresh produce efficiently, a reliable dehydrator is all you need. This investment will not only help in times of need, it will also allow you to save money in the long run.

How to dehydrate foods at home

Dehydrating foods at home is a cost-effective way to preserve fresh produce, nuts and plants. Here’s a simple guide for beginners:

Fruits

Start with ripe, high-quality fruits to ensure the best flavour. Avoid dehydrating bruised fruits as they may turn black when dried. Wash the fruits thoroughly if you plan to keep their skin on, and slice evenly before placing them on dehydrator trays. Dry at 60 degrees Celsius until pliable.

Apples, bananas, peaches and nectarines take six to 16 hours to dehydrate. Apricots, figs, grapes and pears take 20 to 36 hours. Check every few hours and rotate trays. Never add new fruit while dehydrating another batch, as moisture from fresh produce can ruin the partially dried batch.

Vegetables

Vegetables dry faster than fruits but spoil quicker, so prep them quickly before dehydrating. Store them in the fridge or on produce-saving paper before drying. Remove tough skins, bruises and stems before slicing evenly with a food processor or spiralizer. Smaller pieces dry faster. Blanch some veggies (as needed) before dehydrating.

Dry most vegetables at 50 degrees Celsius, except tomatoes and onions (60 degrees). Drying usually takes four to 10 hours, depending on the vegetable. Avoid drying strong-smelling vegetables (like onions, garlic or Brussels sprouts) with mild ones to prevent flavour transfer.

Nuts and seeds

Soaking and dehydrating nuts make them easier to digest by removing enzyme inhibitors. Soak nuts (e.g., almonds, walnuts, cashews, etc.) overnight in saltwater (1 tablespoon of salt per 4 cups nuts). Drain and dehydrate at 60 degrees Celsius for 12 to 24 hours.

Plants

Plants are simple to dry and store well. Harvest them early in the season before flowering. Dry at 30 to 40 degrees Celsius for 2 to 4 hours until brittle (or hang upside-down in a shaded area). Store in jars after removing leaves from stems.

By following these steps, you can efficiently dehydrate different foods, saving money and enjoying preserved flavours all year.

Dehydrating is a budget-friendly food preservation method for most households. For those with gardens or access to seasonal produce, dehydration can transform perishables into shelf-stable staples, combining frugality with flavour.

In an era of food uncertainty, dehydrating food isn’t just about saving pennies – it’s about reclaiming control over what you eat and when. With a dehydrator and a little patience, tomorrow’s meals can start with today’s harvest.
