If the top of a can has a bulge or can be pressed inwards, this is not a quality defect of the product, but is simply a technical phenomenon. When our Carny and GranCarno products are filled into the tins, they are both fresh and chilled, and are then heat-treated during the sterilisation process. This cold-filling system is gentle on our products.
During the sterilisation process, the contents expand due to the increased temperatures. To prevent the filled cans from bursting, they are never filled right up to the top, while maintaining the net weight. The filling level in the cans can vary due to the different raw material compositions for the different varieties. This means that the more voluminous and lighter the raw materials used in a product are, the fuller the can has to be in order to reach the net weight. This may mean that due to expansion during sterilisation, some individual cans have a bulging top, or the top can be easily pressed inwards, although the sterilisation process has taken place in an optimal way.
Before our products leave the production process, every sterilisation procedure is checked. No can will leave production without having been properly and thoroughly heat-treated, because every heat-treatment record for every batch is thoroughly examined by a member of the quality assurance team. Only then is it released for shipping. Any discrepancies in the sterilisation process always lead to the goods being held back. Any problems during sterilisation are also immediately and automatically reported: this rules out the possibility of under-sterilisation of a batch going undetected.
