Today in USISA we have a production area dedicated specifically to this product, our Pressed Sardines. Let’s briefly tell how we do them:

It is always about the species “Sardina Pilchardus”, and the manufacturing process begins with the wet salting phase, which takes place in piles, in which the tempered sardines, salt and brine are introduced, as the Romans already did. Centuries ago.
The sardines are going to be “buried” in these piles of salt between 15 and 45 days, before moving on to the next phase of production in the zone of funding, or work zone, where the expert women of the town are classifying them by size, looking for their uniformity, and introducing them in wooden ‘tabales’ of different sizes.

In the ‘tabal’ of circular form the disposition of the whole sardines is radial, with the tails towards the center and the heads towards the perimeter of the tabal. 3 or 4 layers of sardines are superimposed, until the amount required by the format is completed.

The time in the pressing phase ranges from 3-6 hours, manually manipulating the press to increase the pressure until the moment when all the oil and water of the sardines has been eliminated.

Finally, when it comes to fillets the sardines are packed in trays, there is a phase of cleaning the sardines in an artisanal way by experienced hands, who carefully remove thorns, skins and heads, leaving only the loins, which are to be disposed on These plastic containers, finally adding olive oil. This format is presented in a vacuum, so that, once the trays have been sealed, they are inserted in xerographed cardboard boxes for the final presentation to the consumer.

The product is conserved up to the moment of its expedition in a cold storage chamber, at a controlled temperature between 0-5ºC, and after the shipment, the transport has to be refrigerated until the door of our clients, so that the quality and organoleptic qualities of this exquisite product.
