The first thing to keep in mind is that if you decide to buy a sous vide machine to pack food at home, it is not something that you are going to use only for vacuum cooking and low temperature, but a vacuum food packaging machine is a tool for the kitchen that can be very much at home.
These are the main advantages of having a sous vide machine in your kitchen:
You can pack vacuum foods to preserve them for a longer time, preserving better their flavour, nutrients, texture, qualities, etc. Many of the processes that spoil food are due to oxidation processes that take place when in contact with oxygen in the atmosphere. By vacuum packing food and eliminating this contact, you will be able to greatly extend its duration.
You will prevent frozen foods from drying in the freezer. By vacuum packing your food, you will prevent its surface from drying out when you store it for long periods in the freezer.
You will prevent food from drying out in the refrigerator. Try to vacuum pack cheeses and sausages that you have started (sausages, ham, sausage, fuet, etc.) and you will see how you can keep them for much longer in the fridge and also keeping all its flavour and texture.
You can pack vacuum foods and cook them at low temperature; using sous vide cooking techniques and cooking at low temperature.
You can cook foods to keep them refrigerated or frozen, using the techniques of cooking at low temperature to pasteurize and preserve foods that we have told you in our section of vacuum cooking techniques.
You will be able to preserve foods with very fragile and dedicated textures under vacuum. Many sous vide machines can be used to vacuum in special rigid containers for this purpose and that will allow us to vacuum-pack foods with the most delicate textures (vegetables, berries, raspberries, blackberries, etc.) without damaging them. Textures, which is what would happen if we tried to vacuum-pack them using a plastic bag or roll for vacuum packaging.
You can save money. By vacuum packing food you will be able to extend its useful life enormously, being able to keep them for periods of time up to 5 times longer, avoiding that they spoil in your fridge before you have time to consume them. You can also take advantage of offers and other price decreases in the market, buying larger quantities of food when prices are low and preserving them later to be consumed as you wish.
You can plan better your fridge and your kitchen because you can have vacuum packed food, both raw and cooked, even packaged in individual rations, both in the refrigerator and in the freezer, perfectly labelled and ready to be used when you need it.
You can save space in your refrigerator and in your freezer , because when vacuum packaging food, you can eliminate all the excess air and the need to use Tupperware or other containers to prevent the food from drying out when you store it in the fridge, earning a huge You can also reduce the proliferation of bacteria . Many of the bacteria contained in food need oxygen to live or reproduce. By vacuum packing food we greatly reduce the possibility that they can do so. Keep in mind that there are also bacteria that do not need oxygen to survive and against this type of bacteria the sous vide machines do not offer any improvement in terms of food safety levels.
They occupy little space and have come down so much in price that it is possible to acquire a very good vacuum packing machine for little money.
