When shipping food and other organic carbohydrate cargoes in the transport package, the surface of the cargo may grow mold. In the event of moisture in the circulation process, the mold grows very quickly and even extends into the interior of the cargo, causing it to rot, mold, and deteriorate. Take special protective measures.
The measures to prevent spoilage and deterioration of the package are usually frozen packaging, vacuum packaging or high temperature sterilization. The principle of frozen packaging is to slow bacterial activity and chemical changes in order to extend the storage period, but can not completely eliminate the deterioration of food; high-temperature sterilization can eliminate the microorganisms causing food rot, can be used in the packaging process with high temperature treatment of mildew. Some dried food packaging should prevent water vapour ingress to prevent mildew and corrosion. Choose waterproof vapor and airtight packaging materials, vacuum and air-packed.
Vacuum packaging is also called decompression packaging or exhaust packaging. This kind of package can block the outside moisture from entering the packaging container, and can also prevent the presence of moist air inside the closed moisture-proof packaging and dew condensation when the temperature drops. With vacuum packaging, care should be taken to avoid excessive vacuum. To prevent damage to the packaging material.
To prevent moldy goods in the transport package, anti-mould agents can also be used. There are many types of anti-mold agents. Non-toxic anti-mould agents must be used for food.
