Vacuum packing for the freezer
•
Through thoughtful packaging the device can help to extend the freshness of meals.
It is necessary to pack foodstuffs in as fresh a state as possible.
•
Fragile or easily deforming foodstuffs may become damaged during the vacuum
packing of the fresh product. Fragile products (meat, fish, wild strawberries,
sandwiches etc.) should be initially frozen.
They may be frozen for 24 hours before the frost scorch occurs. After the initial
freezing they may be vacuum packed in the bags and stored for a long time in a
freezer in order to maintain their taste and nutrition values.
•
In order to package liquid foodstuffs, like soups, sauces, or boiled dinners, it is
necessary to first freeze them in appropriate containers and then vacuum pack
them, returning them to the freezer for keeping.
•
Fresh vegetables should be washed or peeled and briefly blanched in boiling water
or microwave, but keeping their freshness and not allowing for overcooking. After
cooling down vacuum pack in any portions.
•
In order to package foodstuffs which are not frozen, it is necessary to use approx.
5cm more plastic film, because in freezing the foodstuffs expand in size. Meat and
fish should be placed on a paper towel, and then vacuum packed together with the
paper towel. In this manner juices from the foodstuffs are absorbed.
•
Prior to packing foodstuffs such as tortilla, crepes, or hamburger patties, it is
necessary to separate them with wax or baking paper. This makes it easier to later
remove selected items and repack the rest for keeping in the freezer.
Vacuum packing for the refrigerator
•
The meals may be prepared earlier in appropriate portions and stored as vacuum
packed in the refrigerator, and then heat as required.
Vacuum packing for the food storage
•
The vacuum packing may also be advantageous in case of foodstuffs which may be
stored in the room temperature (coffee, flour, flour products, sugar, etc.). When such
foodstuffs are not used for a few days, e.g. due to vacations, they should be protected
by vacuum packing. It allows to maintain their freshness and protects them from the
influence of temperature, mould, and insects.
