PROCESS FOR THE PACKAGING OF PRODUCTS, USING A HEAT TREATMENT, AND CLOSED CONTAINER WITH PACKED PRODUCTS, OBTAINED USING A HEAT TREATMENT |
摘要 |
A container or package filled with perishable food materials is closed by a cover presenting a vent hole and the assembly is subjected to sterilization or pasteurization. Thereafter the vent hole is closed by means of a hot melt having a melting point lower than the highest temperature during sterilization or pasteurization. Preferably the hot melt is applied before sterilization or pasteurization and provided with a perforation joining the vent hole. The hot melt may contain a rounded rigid body not melting at the highest sterilization or pasteurization temperature and being able to seal the vent hole, such as a glass bead. After cooling the closed container is under a subatmospheric pressure. The container may be of plastics or glass and the cover may be of plastics or plastic coated metal foil, in such a case the plastic coating has a melting point being higher than the melting point of the hot melt. |
