INTRODUCTION

The fear of pressure canning has significantly decreased over time. How could we not be worried after hearing so many tales from our grandparents about pressure canner explosions? Thanks to greatly improved safety measures and even the materials used to create pressure canners, you can pressure meat, fish, green beans, corn, and other low-acid foods with a PH greater than 4.6 without having to worry about kitchen explosions. Here, you can learn how to master a pressure canner and preserve all of your summer food by using our canning tips and step-by-step guide.

Starting off as a newbie to pressure canning can be a bit intimidating. I was nervous the first time I made my first pressure canned meal, even though I was already familiar with water bath canning. Many thoughts run through my mind. Is this device safe? Am I going to set my kitchen on fire? Did I do it correctly?

I'm glad I made the decision now that I've used my pressure canner for the past eight years at least a few times every month.

Many people believe that pressure cooking with a multi-cooker such as the Instant Pot may be used for canning as well, which is reasonable considering that those equipment serves a variety of purposes and pressure cooking is similar but not quite the same. However, you must use a pressure canner and not a pressure cooker to preserve food under pressure.

The very first step in successful canning is to have a reliable pressure canner. A canner must be easy to use in order to be effective. That means the canner itself should be simple to use and the information offered by the canner should be straightforward to understand. The canner is worth not more than a garage item taking up space if the cooker's lid is too tough to get on and off, or if it is difficult to load and unload jars.

Here's everything you need to know to start pressure canning your own food.

Why Pressure Can?

You can imagine the sweet, juicy, soft on your tongue, grainy like sugary sand, fresh pear that dissolves in your mouth.

Unfortunately, it’s almost impossible to retain that fresh taste due to the high level of water substance in vegetables and fruits make them perishable.

Foods spoilage happens due:

The interaction of food with oxygen

Loss of moisture

Enzymes are found in foods that break down molecules naturally.

The growth of harmful microorganisms like bacteria, yeasts, and molds on the inside damaged, insect-infested, and bruised produce.

Canning and preserving food storage reduces damage. When canning is properly done, it removes oxygen, eliminates enzymes, stops microorganism growth, and promotes the formation of a powerful vacuum in jars, keeping air, liquid, and micro-organisms out. If not done properly, harmful bacteria such as Clostridium botulinum grow.

Pressure canning can kill bacteria by heating food to 240 degrees Fahrenheit. When this temperature is reached, Clostridium botulinum spores, which cause botulism, are destroyed. This is a significant difference from boiling water canning, which destroys the bacteria and food value while preserving low acid foods. But the process is safe because the high temperature kills even the toughest microorganisms.

According to the National Center for Home Food Preservation, Botulism may be triggered by the bacterium Clostridium botulinum growing in canned food. Botulism is a fatal kind of food poison. These bacteria can be found either as vegetative cells or spores. These spores are inactive and dormant structures. Spores and plant seeds are alike; they can live for many years in soil and water without harming them. When the condition for grown are ideal, the spores produce fertile cells quickly and can reproduce a lethal toxin in a matter of days in a environment that includes low moisture acid foods, less than 2 percent oxygen and an average temperature between 40 and 120 degrees Fahrenheit.

Causes Of Food Spoilage

When vegetables and fruits are fully ripe (reach their peak of freshness), they begin to decay and lose their peak (excellent) quality. All fresh products decompose, but some at a faster rate depending on its water content. Oxygen and enzymes inherent in fresh vegetables and fruits begin to destroy the cells, creating an environment that allows microorganisms (mold, bacteria and/or yeast) thrive. As the cells oxidize react with the present oxygen, moisture is released. As a result, fruits and vegetables become discolored, limp and shriveled with abundance of bacteria/yeast/mould in their cells.

How Canning Preserves Food

We preserve fresh vegetables and fruits by either chilling or freezing them (delaying or totally stopping the process of decomposition) or extracting the moisture present in their cells using the canning process. The canning (preserving/bottling) method depletes the cells' oxygen supply, disables enzymes, and kills any bacteria present, creating an environment in which microorganisms cannot thrive (i.e. low oxygen preserve, high acid). When you process canned food in a pressure canner or boiling water canner, you're also establishing an airtight closure that keeps the jar contents within while keeping contaminants (such as germs) out. A tighter seal provides more storage time and a lower risk of contamination.

Pressure Canner

A pressure canner is a very special kind of equipment used in preserving low-acid foods such as fish, meat, and vegetables. These foods are heated under pressure in their own containers to 240 degrees Fahrenheit or higher, which creates steam that cooks, sterilizes, and seals the food in the containers. The only safe way to preserve low-acid foods is to use pressure canning. It's the only way that's been confirmed to destroy any disease-causing germs that may be present. When the pressure within the pressure canner rises, the steam is forced to cook and preserve the food.

Types of Pressure Canners

If you're interested in canning your own food at home, you'll need to invest in a good pressure canner. Pressure canning is the only safe way to can low-acid foods, and it's important to choose a canner that will work well for you.

Pressure canners come in a variety of shapes and sizes. Pressure canners are classified into two types: dial gauge and weighted gauge.

The dial gauge features a dial that indicates the amount of pressure in the canner, whereas the weighted gauge canner rocks or jiggles when under pressure.

Weighted gauges canners make noise when the pressure is released, and the weight shakes or jiggles, but when used properly, they are always accurate. When using a weighted gauge pressure canner, be sure to read the manufacturer's instructions to learn the proper procedure.

Dial gauge canners feature a responsive pressure gauge that measures the canner's internal pressure. They are often damaged or off to some degree as delicate scientific equipment. You could risk the safety of the food you are preserving if your pressure canner's dail gauge does not read correctly. Before you use your pressure canner, you should have it checked to make sure it works well.

There's no testing required for weighted gauges. Simply inspect the safety plugs and rubber seals for wear on a regular basis and replace them as needed.

How To Choose  A pressure Canning Machine

When you are ready to purchase a pressure canner, what you need to keep in mind in order to get the best product for your needs?

First, consider the size of the canner. It is important to buy a canner that is the right size for your needs. If you plan to can large quantities of food, you will need a larger canner. If you only plan to can small quantities of food, you can choose a smaller canner.

First, you will need to decide what size pressure canner you need. Canner sizes are typically classified by the number of pint jars or quart jars that they can hold. A canner that can hold seven quarts is a good size for most families.

Second, you will need to decide what type of pressure canner you want. There are two basic types of pressure canners: electric and stovetop.

Next, consider the features of the canner. Some pressure canners come with additional features such as a built-in timer or a canning rack. These features can be helpful, but they are not essential. Choose a canner with the features that you think will be most helpful to you.

Finally, consider the price of the canner.

Safe Canning Methods

The method of canning you decide to use depends on the acidity level of the food that you want to preserve.

The three methods of food processing that have been scientifically tested and approved are the pressure canner method, the boiling water bath method, and the atmospheric steam canner method. These food processing methods destroy botulinum and other microorganisms. 

Pressure Canning Methods:

Pressure canning is a method of canning that uses pressure to raise the boiling point of water. This allows for the destruction of bacteria and other microorganisms that can cause food spoilage. Pressure canning is the only safe method of canning low-acid foods, such as vegetables, meats, and poultry.

Boiling-water canning involves filling highly acidic food in canning jars and immersing the canning jars in boiling water for a long period to enable every food particle to attain a high temperature enough to destroy microorganisms. Examples of high-acid produce that can be canned using this method are relishes, pickles, vinegar, and chutneys; most fruits; and richly sweetened spreads such as fruit butters, jellies, jams, and preserves.

Atmospheric Steam Canning Method

You can use the steam canning with foods that are naturally acidic in nature or foods that are properly acidified with a pH lesser than or equal to 4.6. Most fruits, pickled vegetables, and preserves fall into this category. The steam canning method is NOT suitable for foods with low acidity such as meat and vegetables.

The atmospheric steam canning method is a new canning method that couples the advantages of water bath canning with the advantages of pressure canning. This canning method is done at atmospheric pressure, which means that there is no need for a pressure canner. Additionally, atmospheric steam canning must be used with naturally acidic or perfectly acidified foods that have a pH less than or equal to 4.6. The prepared jars are placed in a rack over a water container in steam canners. The thermal treatment for the jars is provided by the steam formed by boiling the water.
