Top 5 Disadvantages of Home Canning

There are many good reasons to preserve food through home canning. In fact, the list is quite long, but it also has a number of disadvantages. As many tend to focus on the benefits of canning foods for future use, it is equally important to be aware of some of the drawbacks associated with processing fruits and vegetables for home use.

time commitment

Probably the biggest downside to home canning is the time it takes. The amount of time one must invest in this may be too great for beginners. For example, time must be spent selecting what to process. If you have a garden, you will need time to harvest the crop you want to keep. If you don’t have a garden, you will spend time shopping and gathering produce from other sources. That’s before the actual canning begins.

Then there is the time spent preparing food for canning at home, plus setting up the equipment needed to process the food. This includes cleaning and sterilizing holding equipment, as well as cleaning, peeling, and any other necessary food preparation prior to canning. There is also the time spent processing (canning) the food, allowing it to cool and seal, and all the cleanup. It is quite possible to spend entire days in the kitchen during canning season.

canning equipment

When it comes to home canning, you can’t just soak the jars in a sink of hot water to seal them. There is a long list of canning supplies that have been created specifically for food processing. This includes everything from large canners (for boiling water) and pressure canners to racks, belts, measuring tools, pH testing tools, temperature gauges, and recipe books. Additional equipment required will range from jars and sealers to lids, plugs, labels and more.

The foods you intend to process are also part of the supplies you will need for preservation. Depending on your recipe, this will also require pectin, sugar or pickling spices, herbs, and salt. All of these items will also take up space, so you’ll need to have an area large enough to store all the gear you’ll use with easy access to the pieces you’ll use most often. The best part is that most of their large supplies can be used over and over again with other supplies, like jars, that require regular replacement.

Financial investment

It’s appropriate to add to this list of disadvantages of home canning the cost of all the supplies you’ll need. The items listed above will require a good chunk of change to pay for, but there’s a silver lining buried here. For canneries and many of the larger pieces of equipment, you only have to buy them once. Other smaller items such as pH test paper, jars, caps, lids, labels, and rings will be replaced periodically.

Some items in the home canning process can only be used once, and others can be reused multiple times before you need to replace them. The food products you are processing, unless they come from your own garden, will also increase your cost of production. In general, keep in mind that most of your costs will come from the “start-up” phase of purchasing equipment that you don’t already own or haven’t inherited or been given by a friend or family member.

Home canning losses

Nutrients are defined as the components found in food that an organism requires to survive and grow. The canning process removes a large amount of nutrients from the food that is processed. This is due to the fact that to properly pack fruits or vegetables, a cooking step is required. This cooking step stops the natural enzymatic action that is used to aid in the aging of these foods. Left alone, enzymes cause fruits and vegetables to overripe and spoil.

When cooked, minerals, water-soluble vitamins, and other nutrients can be removed from the food being prepared. They then end up staying in the boiling water that is eventually poured down the drain. By comparison, canned fruits and vegetables contain far fewer vitamins and minerals than fresh. On average, they lose up to 65 percent of these essential items when canned.

Potential health risk

Okay, so you have the recipe(s) you love, all the home canning supplies and equipment you need, foods to process, and now we’re talking health risks. Well, it’s something to keep in mind if you’re preserving food for yourself, your family, friends, or getting into the business of selling canned goods at home. The health risk comes from contamination. This can occur at any level of the home cannery and should be monitored.

Contamination results from acid levels in canned fruits and vegetables. Do you remember seeing the pH test strips listed above as canning equipment? The reason we included that was to keep you aware of the fact that you will need to frequently test for proper pH levels. Various forms of bacteria do not survive the heating process of canning as long as the salt and acid levels are correct. To be safe, follow only proven recipes and study what pH levels are safe for the specific foods you are processing.

The bottom line

Regardless of the fact that home canning is a great way to spread or share a harvest with others, it takes quite a bit of work to complete. Add to this the cost of equipment and supplies and the potential loss of nutrients, as well as the risk of contamination, and preserving food can seem like an intimidating undertaking to anyone. As stated above, the advantages far outweigh the disadvantages. It’s just up to you whether or not you’re ready to become an expert in home canning or not.
