The home machines suck the air from bags and containers and allow food to be stored longer, enhancing taste and nutritional properties
by Simona Preda
Prolonging food storage is an important factor to reduce waste but not only. Removing the air from these foods, in fact, these are preserved longer, because bacteria and mold do not proliferate, and then the deterioration is prevented. Furthermore it is also possible to prepare food in advance, when we have more time, store it with the vacuum system preserving taste and nutritional properties and consume it when you prefer.
To obtain the vacuum is necessary to use special equipment that sucks the air from the bag containing the food and seals it by heat sealing, in a hermetically manner. In addition to bags, to choose for this specific use, some machines also feature cans with valve lid, which must be connected to the appliance with a tube for sucking. The compact package must then be placed in the refrigerator or in the freezer, with the great advantage that no frost forms inside. The storage times vary, however generally they extend up to 5 times. For domestic use, there are several compact-sized devices on the market, in addition to professional built-in solutions.
What kind of foods
What is it possible to preserve? Cured meats, cheese, meat and fish, but also vegetables and dried fruit, so both dry and wet foods, raw and cooked ones. In the case of cooked foods, in general, these are assembled raw with condiments and sauces, for example meat with a sauce or a marinade. Some vacuum machines have the “marinating” function, specific for these preparations. Furthermore, there may be a tray, removable for cleaning, in which any liquid that comes out of the food is collected.
Some kinds of foods can be eaten immediately, just removed, such as cured meats or cheese, while others must be cooked, preferably with the sous vide method. This can be done with a steam oven or by inserting the closed bag in hot water, between 50° and 95°C; temperatures and times depend on the preparation. The great advantage of this type of cooking is that foods are rich in taste, nutrients and flavor, but also with a soft texture, such those of a quality restaurant.
The companies point of view
What is your strategies to make your products known?
Emanuele Marzi , Commercial Director of Van Berkel International: Communication and above all training of our stakeholders on the potential of the product in terms of savings, food freshness, practicality and time saving. From this year we are communicating the enormous advantages deriving from the joint use, at the domestic level, of the slicer and the vacuum machine; winning combination for cutting and storing different foods, not just cold cuts.
Ernesto Picozzi , Home Appliance Marketing Manager of Johnson: We have organized trainings for promoters for the demonstration of our products. Promoters put beside the sales assistants of stores, instructing them on the use of the appliances and collaborating in the presentation of the functionalities. Regarding the on-line sales, it is possible to access, through the QRcode on each product, to demonstration videos that explain the use of the device in detail. This allows the customer to have, in a fast way, the necessary information to know it.
Emanuela Papagni, Foodsaver Product Manager for Nital: We try to implement an integrated strategy that covers the explanation of the product both off-line and on-line. For this reason, we use tools such as brochures, functional stickers to explain the product features, live demonstrations at certain times of the year, promotion on social media and TV channels.
Which features are most appreciated by consumers?
EM: Regarding products for domestic use the most appreciated aspects are (not necessarily in this order): weight and size, power, suction force (which has a direct impact on the speed and quality of the result), materials and assembly quality, numerical of functions, basic equipment and design.
EP: The value for money is the basis for the sale of the product, but it is a winning weapon only if supported by a brand known to the general public. For this reason, Johnson is increasing its investments in advertising, both in sector magazines and in channels aimed at a wider audience (TV, posters …), with the aim of giving greater visibility to the brand, present since over 50 years on the market, as a synonym of guarantee.
EP: The possibility of avoiding waste and thus saving money, for example by taking advantage of offers and thus being able to conserve big quantities much longer.
ML: In the domestic sector consumers demand ease of use and cleanliness, an attractive design, little bulk in terms of size, high performance but with easy-to-perform operations, additional aids such as accessories or a cookbook , in addition to good value for money. In the professional sector they require us high performance, good value for money and an efficient after-sales service.
