Shelf table meals can last for an extended period depending on the method used in their preservation. Some can go even for five years if stored in the right conditions. There are different preservation methods used both commercially and in retail that one can take into consideration. Here are methods used to preserve Shelf Stable Meals Minnesota to take into account.
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. 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.
Use of retortable pouches. Retortable pouches is a new preservation method that is quickly replacing the canning process. It can handle most foods that rely on pasteurization. The food is preheated at a high temperature for a few minutes before packaging. The pouches have a design that keeps off air from the outside which can spoil the food. Foods that relies on this process include those used in space exploration, field camping, and military services.
Acidification. It is a combination of heat and acid method to preserve foods. It targets sour products such as fruit purees, juices, and other pasteurized products. The treatment process starts with heating at around one hundred and ninety-five Fahrenheit and the acidity level lowered to about 4.6 PH. The acid works as an inhibitor reducing the temperature used to heat the product during the initial stage.
Lowering the level of water content. Water content can support the growth of yeast and mold. Lowering the level of water content reduces the possibility of the mold or yeast growth. Dehydration is usually common in draining the level of water or the use of sugars or salt. Water content lowering can go to about 0.65 according to the measurements used in measuring water content in foods.
The freeze drying. The freeze drying process starts with freezing the food then turned into water using a vacuum which results to a dehydrated product. The original shape and quality of the product remain through this process. The initial process can use a biological process using yeasts and bacteria, food processing or a biomedical process. It is common with meals needed for space exploration, military, and backpackers.
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.
