Technology that works behind a Vacuum pouch
Extension of the shelf-life of food products is one of the food technology areas that need to meet the demands of consumers. With this in mind, the packaging industry has put increasing attention on remodeling food storage concepts. Vacuum pouch is the implementation of vacuum packaging technique that completely removes air. After all, you can prevent the aerobic growth of bacteria and mold if you keep them away from air. More specifically if it is away from oxygen. In addition to that, it is a known fact that vacuum pouches extend food shelf life minimum 3 times more than food stored in normal plastic containers like bags or food containers. However, how long it will last that depends on the category of food. Additionally, it depends on food storing area like whether it’s stored in a freeze, a refrigerator or at normal room temperature.
Usually, there is a less retention of the color of foods like meat and poultry in vacuum pouch storing. However, once you remove it and expose to air from the vacuum pouch the color is regained like earlier. Furthermore, the microbial profile of vacuum packaged meat is significantly high. Vacuum pouch offers several unique advantages for retaining the desirable marketing quality of food products. However, the active packaging is an important area of advancement of vacuum packaging technology for further improvement of safety of non-veg products. Further research may ensure more safety in the marketing of meat and poultry products.
It must be remembered that although vacuum pouch shields food from unwanted bacteria that doesn’t mean it will resist all types of bacteria. Hence, vacuum pouched food can’t be left out at room temperature for longer time. Anaerobic bacteria can easily grow without oxygen. Consequently if ingested these can cause illness. This is the reason you need to store them in a freeze. Hence, it is equally important that your vacuum pouch must be freezer safe. Maintaining appropriate temperature is a key criterion in this situation.
