The producers of food items have to focus a lot on the appropriate storage and packing of the items so that the freshness can be maintained by removing oxygen content from the packing.This is how you receive the packets that are said to be free from bacteria or other spoilage.This is done through vacuum packing.If the food items such as potato chips,sugar,nuts,coffee etc.are not protected properly,then they will not be able to maintain their texture and appearance intact.The moist food can be preserved as it will not dry out and dry food will not become hard in the absence of air.
Some of the benefits derived from vacuum packing are summarized below:
Spoilage reduction-By removing oxygen,the food is no longer prone to spoilage.This results in increasing the shelf life of the product.So you can eat your favourite food without any worries
Efficiency in consumption-While cooking food for a large number of people,it will surely be more difficult to cook at one time.With vacuum packing,you will be able to cook with some breaks in between as you know that your food will not get spoilt
Maintaining freshness content-You will find the quality of item preserved with vacuum packing as similar with that of an item that is prepared fresh.This is because there is no spoilage to the contents even after many days of preparation
Safe intake-As the growth of bacteria,yeast is eliminated,the food that you consume will not make you sick.Hence,you can safely buy the food item and eat it as carelessly as you eat a fresh piece of food
Savings-You need not waste your money on spoilt food that happens if you try to store your food item for a longer time as it will get spoilt after some-time.There is no wastage of food and money at the same time
These benefits are really important but vacuum packing is used so widely that people generally do not realize them.
An important point to note here is that the vacuum packing is also widely used for packing non-food items such as woollen sweaters to prevent them from shrinking and silver-antique pieces to prevent them from tarnishing.
While vacuum packing does perform many important functions,it is certainly not a substitute for dehydration and canning.Vacuum packing can prevent the impact of moisture but it cannot perform the function of refrigeration.There are some types of food items that need refrigeration even if they are vacuum packed-meat and dairy products like milk and curd.
For different requirements of users,there are different types of vacuum packing.External vacuum devices remove the air by using an external bag,Chamber vacuum sealers remove air by placing the product in the machine.These help in packing for products that require higher vacuum level.Hence,you need to decide on the type of packing on the basis of your product requirement.
