Fishing And Harvesting
The story begins at sea. Commercial fishing vessels equipped with state-of-the-art technology roam the oceans in search of large schools of fish. When it comes to harvesting seafood like tuna and salmon, various methods are employed, including purse seine nets for schooling fish, long-line fishing for larger, deep-swimming fish, and trolling for catching salmon. These methods are designed to maximize the catch while taking care to reduce by-catch (the capture of non-target species) under international fishing regulations and sustainable practices.
Processing At Sea Or At The Facility
Once the fish are caught, time is of the essence. Many fishing vessels have onboard facilities to process the fish immediately, which involves cleaning, gutting, and pre-cooking. This initial processing helps to preserve the freshness of the fish. The pre-cooking process removes a significant amount of the fat and makes it easier to remove the skin and bones. If processing isn’t done at sea, the fish are quickly frozen and transported to land-based facilities.
Canning And Preservation
Upon arrival at the processing facility, the fish undergo further cleaning and are cut into the appropriate sizes. Then they’re ready for canning. The chunks of fish are placed into cans that have been coated on the inside to prevent corrosion and reaction with the seafood. Alongside the fish, various ingredients like salt, vegetable broth, olive oil, or water are added to enhance flavor and moisture content. It’s essential that the cans are filled to the right level to prevent over or under-stuffing, which can affect the quality of the final product.
Canning technologies have been evolving ever since the industrial age until the current days when canned seafood is still popular. One of the most recognized canning solutions brands could be Hermasa whose machine can run up to 500 cans per minute.
Sealing And Sterilization
Next, the cans are sealed tightly to prevent any contamination. After sealing, comes the sterilization process—cans are placed in a pressure cooker or retort and heated to a specific temperature for a set period. This high heat is necessary to kill any bacteria or pathogens that could spoil the fish or be a risk to human health. It also cooks the fish thoroughly, making it shelf-stable and safe to store for long periods without refrigeration.
Secondary Packaging For Branding Enhancement
The most popular form of secondary packaging is the carton sleeve that is able to be designed in various forms, shapes, sizes, and styles to carry multiple cans of seafood at a time. A sleeve carton is also an excellent packaging option now that provides outstanding marketing performance that helps a brand to catch customers’ constant attention.
However, designing the right form of sleeve carton requires certain professionalism around packaging now that the tightness is essential for multipack cans. Features like an edge lock or rim can help to secure the can’s fringe so that these rounded containers will not slide out of the packaging. One of the most well-known companies specializing in cartoning and sleeving solutions is Absolutely ELITER Packaging Machinery which has been working with various canned seafood brands the secondary packaging for its products.
Distribution
The last step in the journey is getting these cans into the hands of the consumers. Finished cans are packed into boxes, loaded onto trucks, ships, or trains, and distributed worldwide. Retailers then stock these cans on the shelves, making it easy for consumers like you to find and purchase them.
