The use of shelf table foods is common in many places. They are common in preserving food rations and military food supplies. Most people prefer using these foods since they are ready-made and do not require a lot of preparation. You can adopt different preservation methods, especially for commercial usage. Below are thoughts on how to preserve shelf stable meals Minnesota.
Canning. Canning involves preserving food in a sealed an airtight container. It can provide a shelf life for about three to five years. Free-dried canned products can last for more than thirty years. There are two methods that one can use in canning. It includes the boiling water bath method and the pressure canning process. The boiling water process is safe for fruits, pickles, jams, and other preserves. Pressure canning is safe for poultry, vegetables, meats, and seafood.
Aseptic processing. This technique is common with milk products, yogurts, and fruit juices. It allows sterilization outside the container using an ultra-high temperature system. Besides that, one can use a direct heat transfer process achieved using steam infusion and steam injection. Standard methods used to sterilize the containers include heat, chemical sterilization, radiation, and hot water.
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 is a conventional method used to preserve meals used by backpackers, space explorers, and the military. The procedure starts with quickly freezing the food and turning it to water using a vacuum process. It maintains the quality and shape of the product. It can include biomedical procedures, biological which provides for bacteria use and yeast and food processing.
These processes have a couple of disadvantages despite their suitability. To start with, they have extra preservatives that might be unhealthy to their users. They are also low in nutrients, especially when made in very high or low temperature that destroys different nutrients. Besides that, their serving can be smaller than the required amount for multiple meals.
