Food Preservation Techniques Before the Widespread Use of Refrigerators

At the turn of the 20th century, before refrigerators became a commonplace household appliance, people relied on a variety of methods to keep their food fresh and preserve it for longer periods. Here, we explore the common practices used during this time, many of which are still relevant today.

Salting and Curing

Salt was a widely used preservative for meats and fish. Curing involved treating food with salt, sugar, and sometimes nitrates to inhibit bacterial growth. This method was particularly effective for long-term storage, especially for meats such as pork and beef. Cured products such as corned beef, bacon, and ham were popular additions to the diet during the early 20th century.

Drying

Drying was another traditional method used to preserve both fruits and vegetables. By removing moisture, the food became less hospitable to microbes, thus reducing the risk of spoilage. Fruits like raisins, nuts, and apricots were commonly dried in the sun, while vegetables such as tomatoes, beans, and peppers could be dried in ovens to create a longer-lasting food supply.

Canning

The canning process, which became popular in the late 19th century, continued to grow in acceptance during the early 20th century. Foods were cooked and sealed in jars or cans, creating a vacuum that prevented spoilage. This method allowed for a wide variety of foods to be preserved, from fruits and vegetables to meats and soups. Canning was a reliable way to ensure that food supplies lasted through the winter months.

Pickling

Pickling was a method used to preserve both vegetables and fruits by immersing them in vinegar or brine (saltwater). This process not only preserved the food but also added flavor. Common pickled items included cucumbers, beets, and various types of fruit. Pickling was particularly popular in colder regions where fresh produce was scarce.

Fermentation

Fermentation was used to preserve a wide range of foods, including sauerkraut, kimchi, and yogurt. This process involves using beneficial bacteria to inhibit spoilage and enhance the flavor of the food. Fermented foods not only extended the shelf life of the food but also improved its nutritional value through the fermentation process.

Cold Storage

Many households employed iceboxes, which were insulated containers holding blocks of ice to keep food cool. Ice was often harvested from local lakes during the winter and stored in icehouses for use during the warmer months. While these iceboxes provided a degree of cooling, they were not as efficient as modern refrigerators.

Dry Storage

Basements and root cellars were utilized for cold storage. These cool, dark spaces provided a stable environment for storing root vegetables, canned goods, and other perishables. The consistent temperature and lack of light in these areas helped to maintain the freshness of the stored food.

Sugar Preservation

A common method for preserving fruits, especially during the early 20th century, was the creation of jams and jellies. These products were made by cooking the fruit with sugar, which created a thick, sweet product that could be stored for long periods. This method not only preserved the fruit but also added it to the diet during the off-season.

In conclusion, the food preservation methods used at the beginning of the 20th century were a blend of traditional practices and innovations of the time. These methods allowed households to manage their food supplies effectively and ensure they had a regular supply of fresh and preserved food. While some of these techniques have fallen out of common use, others, such as canning, pickling, and drying, remain popular in modern times.
