Preserved foods are common in many places. Shelf stable meals are ready-made foods preserved for use after a long time. They can even go for about three years and maintain their edibility. There are various preservation methods that one can use to preserve the meals for a long time. The following are preservation methods for shelf stable meals Minnesota to consider.
Canning method. The canning method has been used over a long time. It can preserve a meal for about five years and even more especially those that are free-dried. There are two methods that one can use in this process. These methods include pressure canning and boiling in water baths. The boiling water procedure preserves foods such as jams, fruits, pickles, and other types. The pressure canning method preserves seafood, vegetables, and poultry.
Aseptic processing method. This method is common with milk products and juices. The content uses an ultra-high temperature system in sterilization. Also, one can also use a direct transfer of heat procedure that relies on steam injection or infusion. Sterilization of the container used in the container relies on radiation, hot water, heat, and chemical sterilizers.
Retortable pouch. The retortable pouch method uses flexible plastics and metal foils in the packaging process. It can handle foods and drinks commonly used in the aseptic procedure. One should preheat the food in high temperature for a few minutes. The pouches have a design that cannot permit entry of air that can spoil the food from outside. They are common in camping, field rations, and military and space foods.
Use of acid. The acidification process is a combined process that relies on heating and acid. It targets sour foods with higher Ph. Most foods that depend on this process are purees made out of citrus fruits. Heating can go up to around ninety degrees whereas the acidity level lowered to about 4.6Ph. Acidification uses less heat compared with the one used in the aseptic process.
Lowering the water content. Water available in foods supports the growth of yeast and mold. However, reducing the water activity to approximately 0.65 according to the standard water unit in foods. The process relies on dehydration, the addition of salts and sugars. For that reason, products such as beef jerky, jams and raising can last for a long time.
Freeze drying. This process is common with meals for backpackers, military and astronauts. Food is quickly frozen, and the ice turned to water vapor by removing food in a vacuum resulting in a dehydrated product. It maintains the original shape of a product and maintains quality in the product as well. Its primary applications include biological methods such as bacteria and yeasts, biomedical and food processing.
Although there are advantages of these processes, there are a few setbacks for using shelf foods. To start with, some additives used in the process can irritate some users. It also lowers the level of nutrients primarily through the freezing process and heating in high temperature. Also, most foods produced through this process cannot meet the requirements of multiple servings.
