"Microwave Foil increasingly popular"
Laser-perforated foil
Sap'Fresh is laser-perforated foil, which is used to extend the shelf life of vegetables. "Every product breathes differently, so the permeability of the foil varies per product." The permeability of oxygen, carbon dioxide (CO2) and water vapour is adapted to the product, while varying temperatures during processing, packaging, storage and in the store, are taken into account. Thus, the quality of the product is retained for quite a long time. "You see, for instance, that outdoor vegetables breathe much more than greenhouse vegetables, and are therefore more susceptible to aging. A cucumber will not likely be found in Sap'Fresh, but products like leeks, radishes, carrots, chicory and asparagus are ideal for packaging with this type of foil," Marcel explains.
Microwave foil
The Cook'n Sap microwave foil is based on the Sap'Fresh foil. This foil is used to simmer vegetables more quickly in the microwave. "A programmed opening in the container achieves a controlled, constant excess pressure in the bag. In this way, the vegetables are cooked properly, and the taste and the quality of the product is retained." Marcel says the concept is fast gaining ground. "Convenience products are doing quite well, but microwave meals were long considered not to be healthy. In recent years, steam containers have been growing strongly. The big advantage of the latter is the preservation of flavour, color and nutritional value." A further advance of these packages, he thinks, is to be expected in the coming years.
