A preliminary inspection revealed that it was possible for cocaine to have been hidden with the shipment.
Officers decided to observe the final destination of the container rather than move in right away.
They then followed the lorry to an industrial area in Els Mojons.
The Guardia stormed into a warehouse, where they surprised two men as they worked on the container in order to extract the cocaine.
Officers also removed the tools used to remove the cocaine packs from the containers and repair them.
Double bottoms were used by the unit to bring cocaine from South America into Spain.
The court decided that since the pineapples had been declared as edible at a customs border, they should be given to the Valencia Food Bank.
