How To Preserve Food Properly

There are many ways to preserve foods, depending on what kind of food you want to store. For a cooked meal, you can freeze it, and it will last for a week. For raw items like fruits and vegetables, canning & fermenting is the best option. For meats, freezing them is the way to preserve them.

Food fermentation uses a culture of beneficial bacteria to preserve food at home and also has many health benefits along with the benefits of storage. Fermentation is an age-old form of food storage that actually increases the health benefits of food, while other methods can worsen it. Food storage includes food processing techniques that prevent the growth of microorganisms such as yeast (although some methods work by introducing benign bacteria or fungi into the food) and slow the oxidation of rancid-causing fats.

Other food preservation methods described in this book—sugar, salt, oil, vinegar, wine, and alcohol—are more limited, but still interesting. Some home storage methods are outdated, such as refrigeration, while others are newer, such as freeze drying. Additionally, there are now more (safe and proven) ways to store food than ever before, including some that we haven’t even covered here, such as freeze drying, and of course good refrigeration for short to medium term food storage. .

The National Home Food Storage Center provides a comprehensive list of ways to freeze a range of foods, as well as general information about frozen food storage, defrosting, and preparing food for serving. Always be sure to follow the latest canning guidelines to ensure the healthiest and safest canned foods available, such as through the USDA National Home Canning Center. Use one of these tips to preserve inexpensive, seasonal produce by canning, pickling, fermenting, drying, and storing.

Compared to canning and freezing, which involve extreme temperatures, dried foods are the least harmful form of food storage. You can extend the shelf life of fermented foods by canning, but the heat from the canning process can destroy beneficial crops.

In order to preserve a wider range of non-acidic foods such as green beans or meat, a pressurized canister must be used to adequately heat the food to kill pathogens. To prevent weakening, the most radical method is to simply kill microorganisms, mainly bacteria, by placing the food in an airtight container and then heating it to above 100°C/212°F for a sufficient period of time. This method involves cooking food in a container covered with boiling water and cooking for some time.

Water bath canning involves submerging food jars in a boiling water bath, ensuring that the pH of the food is 4.6 or lower for safe storage at home. Water bath canning is a shorter, cooler canning process for high-acid foods such as fruit, jams and jellies, chutneys, pickles, and condiments. Foods that are safe to submerge in water are most fruits, jams, jellies, fruit oils, fruit syrups, chutneys, jams, pickles, ketchup, and sauces.

Food can be dried in hot air or in an oven, or sealed in a concentrated salt or sugar solution that extracts moisture by osmosis. Most foods can be stored in very dry, salty soil (hence the desiccant), such as sand or frozen soil.

Preserving food in salt and sugar was more common before modern canning, freezing, and dehydration became available. For many years, food has been cooked commercially in jars (hence the term “canning” rather than “drying”). A French chef named Nicolas Appert invented canning after realizing that if wine could be stored in glass, food could be stored if it was sealed and heated.

Another traditional way of storing meat, seafood, and some vegetables was canning, the process of packing food in a jar and sealing it with fat to protect it from microorganisms and oxygen.

Removing moisture is a key goal of many canning methods, including salting, drying and smoking, says food historian Mercy Ingram, who teaches open-fire cooking and historical food preservation techniques in Hulmeville, Pennsylvania. The historical approach has been to keep food out of air by first soaking the food in pathogen-killing agents such as acid, alcohol, salt, sugar, or a combination, and then sealing the food in containers with tallow, pork bladders, flannel, or skin. . Some storage methods go well together, such as freezing, which works best if you vacuum seal foods first to reduce freezer burns.

Home freeze drying preserves many foods that otherwise do not store well, such as dairy products, whole meals (hot meals, cream-based soups, etc.) and leftovers. Another option for storing food at home is freezing dry food, however I didn’t mention it as one of these storage methods because home freezers are still quite expensive, making them a very expensive storage option.

The word “preserve” in use today (like the French word “preserves”) is associated with nothing more than preserves or jars preserved by sterilization. In other processes, the canning process often improves the flavor of the food rather than its nutritional value. By preserving food, you can reduce food waste, which is an important way to reduce production costs and improve the efficiency of food systems, improve food security and nutrition, and promote environmental sustainability.
