There are a wide number of modern day techniques and machines that help us preserve food and store abundance for later.
Most Popular Methods:
- Vacuum Sealing
Why It’s Important??
Food waste is a very large problem, especially in America. Americans lead the world in food waste. It is estimated that about 50% of all produce in the United States is thrown away. This percentage is closer to 30% on a global scale. That is approximately 1.3 billion tonnes worth of food wasted (about $3 trillion USD in value). Anything we can do to preserve our food so it doesn’t end up in the trash will help reduce this waste.
Food dehydrating is the process of removing water from food by circulating hot, dry air through the food. This is done at a temperature low enough not to cook the food. When food is dried using this process, it inhibits the growth of bacteria, yeast, mold, and other microorganisms (aka enzymes). This method has been used for thousands of years and is traditionally executed through evaporation by using the sun to dry foods. However, with the invent of food dehydrators, the process can be completed much more efficiently and with more consistent results.
Dehydration minimally affects the nutrients of the food. Some foods may taste sweeter because of the water content being removed and thereby increasing the concentration of sugars. Compared with freezing or canning food, food dehydration is the least damaging food preservation method. Here are a few details:
- Calorie count is not impacted.
- Food retains most of its Vitamin C and all of its Vitamin A.
- Fiber and carbohydrates, as well as minerals such as potassium, are retained.
Many companies charge a pretty penny for packaged dehydrated food such as jerky and fruit leathers. Making these healthy treats, yourself isn’t as hard as they would like you to think. By dehydrating food, you can make as much as you want at a low cost, and if you have extra it can easily be stored for later.
