Antibacterial properties can be obtained by the use of granules contain nanomaterial. The “antibacterial activity” were evaluated by ISIRI 10900 standard “Measurement of antibacterial activity on plastics and other non-porous surfaces. Antibacterial activity is an indicator of the product ability to eliminate bacteria. It is obtained by comparison of bacteria number present on control and nanometric samples after 24 hours’ exposure. According to standard, when the antibacterial activity of the product is between 2 and 3, the effectiveness is good. If antibacterial activity is greater than 3, the effectiveness is intense and strong.
Refrigerators and freezers have become one of the main requirements in all kitchens because most foodstuffs can stand out only a few hours or at most a few days in ambient temperature. These household appliances can postpone food spoilage and as a result reduce waste of them. It can be noted that bacteria that exist in refrigerators increases food spoilage and reduces food storage time. They can even cause illnesses. This product includes both refrigerator and freezer in one package so it can be useful for small kitchens and customers that don’t need big storage places. To reduce the amount of bacteria in refrigerators and then food spoilage, refrigerators with antibacterial inside wall have been developed in which nanotechnology are used.
