    Natural products

    • Delfín sea prducts are deep-frozen (extra fast freezing) inmediately after its capture, in order to preserve the taste and the nutritional value of the fresh products.
    • The deep-freezing process consist of freezing completely a product in less than 2 hours. To achieve this, it is necessary to have freezing edge technology machines, which reach temperatures of -40ºC. In this way, the temperature of the product drops very quickly and avoids that the cells of the product are broken. The properties of the sea product remain intact. In a traditional unprofessional freezing, the product freezes very slowly, which will make that part of its properties are lost.

    • Before its consumption it is recommened to defreeze the product in the lower part of the fridge. The time that is needed for this defreezing process depends on the size/weight of the product:
      • For big pieces, such as: fish fillets and loins, lobsters, edible rock crabs, etc. Let them defreeze during 24h.
      • For smaller pieces: prawns, ready-to-eat products, etc. Let them defreeze during 12h.
