How can I clean the machines after their use?
The machines must be cleaned with a soft cloth soaked with water and a neutral detergent. Avoid using products that can abrade or damage the machine surface. Do not use water directly on the machine because there is the risk that it enters in the internal parts of the device, causing damages.
If I use the machine seldom, may I follow some particular steps for the maintenance?
Only for the chamber machines it is recommended to proceed with the heating and cleaning operation (“gastro/pump” button, see manual) in order to heat and clean the pump if the machines has not been used for some months.
After having put a food under vacuum, can I preserve it in the freezer?
Of course. The preservation under vacuum in freezer avoids the creation of ice in the bag and the loss of the product nutritive substances when defrosted.
With the preservation under vacuum does the preservation time increase or it remains the same?
The preservation under vacuum, both in the fridge and freezer, increases the life cycle of the product compared to the natural preservation. This time increase depends on the type of product, on its state (fresh, cooked, etc) and on its quality.
Which kind of food is it possible to vacuum pack?
It is possible to preserve any kind of food except foods that tend to ferment in the absence of oxygen (such as potatoes, avocado, etc.) provided it is not warmer than 25°C, otherwise steam could weaken the sealing and enter into the pump, by damaging oil. Always assure that the sealing part of the bag is perfectly dry before proceeding with the vacuum cycle.
Which kind of food is it possible to sous-vide cook?
It is possible to cook any kind of food, although meat (poultry, beef, veal, pork…) and fish (salmon, tuna, halibut…) enhance at best their nutritional properties and their flavors through this innovative low temperature cooking technique. Veggies, fruit and even eggs might be cooked sous-vide with excellent results. Sauces – both for salted and sweet meals – are deliciously realized through the sous- vide cooking, by becoming extremely creamy and wisely mixing their single ingredients within the pouch.
How longer can food last once it is vacuumed?
Thanks to the air extraction and the total absence of oxygen into the pouch, the bacteria proliferation is strongly limited, if not even avoided through the vacuum packaging. Therefore the shelf-life of vacuumed food can be extended up to its double, or even three time longer than standard packaging. This general rule is valid only when handling fresh food and not after food has been in touch with open air contamination.
Which is the main difference between the bags Besser Vacuum and the normal bags for the food preservation?
The normal bags aren’t efficent for the elimination of the air stagnation in the bag because they do not have a “barrier” allowing to keep the vacuum in the bag: this can cause a fast food deterioration. The bags Besser Vacuum are made with a special film PA/PE suitable for the food preservation under vacuum and they are available in the smooth or embossed version, and in different sizes.
Which is the difference between a smooth and an embossed vacuum bag?
Both bags are made with the same material (PA/PE) but with different thicknesses. The smooth bag is available in various grammages (70, 90 and 140 my), while the embossed bag is available in 90 my. The main difference concerns the utilization type: the smooth bag is suitable for chamber vacuum packaging machines while the embossed one must be used with external suction machines. In the chamber machine, when desiring an external vacuum (the bag is put exteriorly to the chamber) it is recommended to use an embossed bag because the special embossing allows to extract the air from the bag. It is necessary to follow these recommendations in order to have an optimal vacuum.
Can I use the same bag more times for a new vacuum?
Besser Vacuum doesn’t recommend the re-use of the bags because there may be food residuals or humidity in the bag. This is negative on both the hygienic and vacuum quality point of view. If the bag is perfectly clean and without residuals, it can be reused.
