The History of the Food Can
The food can is a common household object, but did you know it has a complicated history? Cans are made from tin-coated steel and contain sodium chloride for sterilization. They come in many shapes and sizes. Learn about the different types of food cans and why they're so popular! You'll also learn how to recycle your food can. And what's even better, you can reuse your food can as a compost bin!
Cans are made of tin-coated steel
Tin-coated steel food cans are an excellent alternative to glass jars when preserving or preparing foods. In fact, they're often safer than glass, and can even be used to make homemade jam and preserves. Moreover, tin-coated steel jars are resistant to corrosion and are durable. However, there's one important thing you should know before using them. Here's why.
They contain sodium chloride
Sodium chloride is used to extend the shelf life of canned foods and is added to the process to add flavor and texture. It is used in various food products as an anti-caking agent, thickener, and stabilizer. The addition of calcium chloride may also correct mineral deficiencies and improve texture. Most canned vegetables contain sodium chloride. However, canned tomatoes, peppers, and cucumbers do not contain this ingredient.
They are sterilized in a boiling water bath
When canning food, the process of heat sterilization in a boiling water bath kills microorganisms. This is used to prepare canned food for long-term storage. Food is sterilized by the time the water in the pan reaches 100 degrees Celsius. The temperature of the water should not be violent, and the time is measured from the time the product begins to boil.
They have a variety of shapes
Food Cans come in many different shapes, including round, oval, and square. While the traditional shape of a can is cylindrical, there are now several varieties of the container. The three-piece structure consists of a flat sheet of food-grade metal and two end lids that are joined by a vertical seam. Corrugated surfaces add strength to the can, and the two ends are then sealed together at the top. The seams of three-piece cans are sometimes joined by welding or soldering.
They are used to preserve foods
Plastic cans have many advantages over traditional tinplate, glass and metal jars. They are lightweight and dimensionally stable. They can also be shaped and printed with a variety of designs. Whether or not they are ideal depends on the application and product. Plastic cans are becoming a popular option for preserving foods, but glass and metal jars remain the most common choice. The advantages of plastic jars over glass and metal jars are not indisputable.
They are inexpensive
Why are food cans inexpensive? Unlike fresh food, canned items are often harvested and packaged during the peak of their freshness. They are shipped to retailers less expensively, and are stored for longer periods of time. There are countless varieties of foods in cans, including meat, vegetables, and fruits. In addition to being affordable, canned foods are often fresher and have a longer shelf life. Canned meat and vegetables have different tastes than fresh, and they can be stored longer.
