Edible films/coatings have been considered as one of the potential technologies that can be used to increase the
storability of foods and to improve the existent packaging technology, helping to ensure the microbial safety and the preservation
of food from the influence of external factors. Innovations constantly appear in food packaging, always aiming at
creating a more efficient quality preservation system while improving foods' attractiveness and marketability. The utilization
of renewable sources for packaging materials, such as hydrocolloids and lipids from biological origin, is one the main
trends of the industry. These films should have acceptable sensory characteristics, appropriate barrier properties (CO2, O2,
water, oil), microbial, biochemical and physicochemical stability, they should be safe, and produced by simple technology
in low cost. Also they can act as effective carrier for antioxidant, flavor, color and nutritional or anti-microbial additives.
Nowadays, a great discussion exists about the potential applications of edible films/coatings on food products. The
general trend is to find the correct combination between the food product and the edible film/coating, which will
ensure the success of the technology.
