Key Takeaways
- Canning and dehydrating vegetables is a popular preservation method with increased nutrition and convenience.
- Preparation for dehydrating canned vegetables involves rinsing, draining, and following instructions of the drying device used (dehydrator or oven).
- Proper storage of dried canned veggies includes airtight containers/vacuum sealing to ensure freshness up to 10 years.
Understanding Canned Vegetables and Dehydration
Canning vegetables, a popular preservation method, involves sealing food in an airtight container and subjecting it to heat to eliminate bacteria or microorganisms. This process can also make dehydrating canned vegetables easier, as the heat from canning can cause some of the water in the vegetables to evaporate. Dehydrating vegetables provides an increased level of nutrition and vibrancy to trail and emergency meals. Although fresh vegetables are the optimal choice for dehydration, frozen and canned vegetables can also be dehydrated, with canned vegetables being the simplest to dehydrate.
Dehydrating canned vegetables is a straightforward process, allowing you to create various dehydrated foods for long-term storage and use in different recipes. This post will examine:
- The science of canning vegetables
- Comparison of dehydration options for fresh, frozen, and canned vegetables
- Advice on dehydrating and storing canned vegetables at home.
The Science Behind Canning Vegetables
Canning vegetables entails enclosing them in airtight containers like cans or jars, then heating them to a high temperature to kill any present bacteria or microorganisms. Canning can be done either in a factory using machines or at home using water-bath canning or pressure canning methods. One of the advantages of canning vegetables, including canned beans, is that it saves time compared to cooking fresh vegetables and allows for effective rehydration in meals.
The canning process, if done correctly, does not reduce the nutritional value of the vegetables, making them suitable for creating dehydrated meals. For those mindful of their health, rinsing canned vegetables, such as mixed vegetables, before dehydrating is a good practice. This will reduce the sodium content in them significantly.
Comparing Fresh, Frozen, and Canned Vegetables for Dehydration
Fresh vegetables can be dehydrated in their raw state, while frozen and canned vegetables need to be precooked prior to dehydrating. When using dehydrated vegetables in recipes, you can add flavor by using ingredients like soy sauce. Dicing or slicing the vegetables and spreading them in a single layer on dehydrator trays is the process for dehydrating raw vegetables. To rehydrate them, you can use food soaks or add them directly to soups and stews.
Frozen vegetables can be used for drying. Examples include:
- Corn
- Peas
- Broccoli
- Green beans, which can be turned into dried green beans
- Okra
It is suggested to steam them for a period of six to eight minutes before dehydrating.
On the other hand, canned vegetables can be used to dehydrate vegetables by simmering them in a soup or stew.
Keep in mind that certain vegetables, like lima beans, should not be included in mixed vegetable dehydration.
How to Dehydrate Canned Vegetables at Home
You can dehydrate canned vegetables at home using either a food dehydrator or an oven. Proper preparation of the vegetables is key to successful dehydration in both cases.
The following sections will cover preparation of canned vegetables for dehydration and the dehydration process itself, using either a food dehydrator or an oven.
Preparing Canned Vegetables for Dehydration
Before dehydrating canned vegetables, it is recommended to follow these steps:
- Rinse the vegetables in fresh water for 15-20 minutes to remove any extra liquid or residue.
- Drain the canned vegetables by spreading them evenly on dryer trays and allowing them to drain and air dry for a few minutes to eliminate any remaining moisture.
- Once the vegetables are adequately prepared, you can initiate the dehydration process following the instructions for your respective dehydrator or oven.
Using a Food Dehydrator
Dehydrating canned vegetables using a food dehydrator is quite simple. Here’s how:
- Start by spreading the vegetables in a single layer on dehydrator trays covered with nonstick sheets or parchment paper.
- The recommended temperature for dehydrating most vegetables is 125°F (52°C).
- The exact drying time may vary depending on the type and thickness of the vegetables, but it generally takes between 4 to 6 hours for them to become dry and leathery.
Make sure to periodically turn the vegetable pieces and switch the positions of the trays during the dehydration process to achieve uniform drying. Once the vegetables are completely dehydrated, remove them from the dehydrator and allow them to cool before storing them in airtight containers or vacuum-sealed bags to maintain their freshness.
Using an Oven
If you don’t have a food dehydrator, you can still dehydrate canned vegetables using an oven. To do this, follow these steps:
- Preheat your oven to a low temperature, around 140-150°F (60-65°C).
- Drain the canned vegetables and spread them out in a single layer on a baking sheet or wire rack.
- Place the baking sheet or rack in the oven and leave the oven door slightly ajar to allow moisture to escape.
- Dry the vegetables in the oven for approximately 4 to 6 hours, or until they are brittle and fully dehydrated.
Monitor the progress of the vegetables periodically and turn them occasionally to ensure even drying. Once the vegetables are completely dehydrated, remove them from the oven and allow them to cool. Store the dehydrated vegetables in airtight containers or vacuum-sealed bags to maintain their freshness.
