The Benefits of Using a Food Can

Some foods can spoil without the microbial activity of bacteria. These foods are called "food cans." Moreover, some nonmicrobial causes of food spoilage are a result of metal contamination. During the blanching process, corn and seafood may become blue or black, a result of the reaction of proteins with sulfur compounds. Food cans with enamel-lined lids will eliminate these issues. These products are referred to as "enameled" food cans.

The process of canning has changed the way food is stored. Unlike before, canned food cans have airtight lids that do not leak. In addition, some cans now exhibit a packing code, which allows manufacturers to track the product in interstate commerce. This code helps the manufacturer identify and rotate stock. Furthermore, the code may refer to the date of manufacture, although it is not meant as a "use-by" date. On the other hand, food cans may also display "open" and calendar dates, which are usually the "best-if used by" dates.

Traditionally, a food can is made from three pieces, the body, and the lid. These two pieces are connected with a seam at the top, creating an airtight seal. Aside from this, the seams are also airtight, which keeps bacteria and other microorganisms out. The double-seamed design was invented in the early 1900s in Europe. This innovation eliminated the need for soldering, allowing manufacturers to produce food cans in higher numbers.

Another benefit of canned food is that it preserves the quality of the food. Foods canned in a pressure canner are low-acid and thus do not lose their nutritional value. This ensures that the food is safe to eat. The food cans have a long shelf life and can be stored at room temperature for years. Its quality and safety are unmatched. There are many advantages to using food cans in your kitchen.

The nutritional value of canned foods is also high, and the process is completely recyclable. Additionally, food in a food can is also lightweight, requiring zero energy during storage. Consumers are increasingly turning toward convenience foods and products that can easily be stored. These include convenience, health, nutrition, weight control, and sustainability. Aside from these, canned products are more environmentally friendly than their shelf-life counterparts. Therefore, it makes sense to use them as much as possible.

Aseptic food packaging was first developed in Europe and introduced to the United States in the early 1980s. Compared to retort packaging, aseptic packaging involves the rapid cooling and sterilization of food without further processing. Furthermore, food cans contain bisphenol-A (BPA), which is suspected to be a potential cause of health issues. Considering this information, consumers should carefully choose a variety of canned products to avoid BPA exposure.

Commercial canning is done under strict conditions, including sanitation, temperature, and pressure. However, food cans can still be damaged during shipping. A common shipping incident can cause damage to a food can, making it unusable. However, canned foods have a shelf life of 6 months or more. They can also be frozen for longer than fresh foods. Aside from providing convenient access to more nutritious foods, canning helps ensure quality, safe, and healthy foods year-round.
