DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION

[0030] The present invention discloses a process for obtaining a salted edible substance (A) from halophyte plants.

[0031] As schematically represented in FIG. 1, said process can include the harvest of halophyte plants of at least one species, for providing a first quantity of halophyte plants (1).

[0032] According to a first aspect, said first quantity of halophyte plants (1) includes at least Salicornia ramosissima.

[0033] The process can include a step of dehydration of said quantity of halophyte plants (1), and of grinding said first quantity of halophyte plants (1), thereby obtaining said edible substance (A).

[0034] Said step of dehydration can be carried out in natural drying greenhouses, or in drying devices with supply of final energy.

[0035] Said step of grinding can include the use of a device adapted for grinding of vegetal matter 1, and for obtaining with a characteristic dimension in the range between 0.1 and 10 mm, preferentially between 0.3 and 5 mm.

[0036] The process further includes the step of supplying dosed portions of said salted edible substance (A) to respective recipients (2).

[0037] The process according to the present invention does not include the submission of said first quantity of halophyte plants (1) to a temperature above 95° C., preferentially above 60° C. In particular, it is preferred when the dehydration is carried out by means of natural heating and ventilation.

[0038] Moreover, the process further does not include the interaction of said first quantity of halophyte plants (1) with other substance besides water, preferentially salted water.

[0039] In particular, the salted edible substance (A) including the species Salicornia ramosissima has proved as advantageous given the physical-chemical characteristics thereof, the relatively reduced proportion of sodium relative to the salinity content, and further presence of nutrients, with contribution to the use of the edible substance in food in general, and in the preparation of food as substitute of salt, in particular.

[0040] A system of salted edible substances (A, A′) can include a plurality of substances that, as provided in a respective recipient (2), differ in at least one of the following parameters: [0041] fraction of Salicornia ramosissima; [0042] relative dehydration degree; [0043] relative dimension after grinding; [0044] combination with other edible substances in the recipient (2).

[0045] According to the preferred embodiment represented in FIG. 2, the process of obtaining said first quantity of halophyte plants (1), includes harvesting of halophyte plants, including the species Salicornia ramosissima.

[0046] In particular, said harvest is carried out from spaces of aquaculture of Salicornia ramosissima in salted water, including natural spaces and built spaces.

[0047] After the harvest, there can be a step of washing the halophyte plants, using salted water for this purpose.

[0048] After the washing there can be a screening of the harvested matter so as to separate the halophyte plants from the remaining vegetal matters and eventual residues, as well as a first separation of part, so as to obtain said first quantity of halophyte plants (1).

[0049] As schematically represented in FIG. 3, the step of dehydration of the first quantities of halophyte plants (1) can include a first step of rest at ambient temperature, or with the support of passive means, such as for example greenhouse. This first step is carried out immediately after washing of said first quantity of halophyte plants (1) and before of a second step of drying at a temperature higher than the ambient temperature.

[0050] The author verified that this first step of rest is important to ensure maintenance of the nutritional proprieties of the halophyte plants.

[0051] This first step of rest can be carried out with said first quantities of halophyte plants (1) provided in vertically disposed trays.

[0052] FIG. 4 schematically represents a system of said salted edible substances (A, A′) provided in recipients (2, 2′) adapted so that can be closed, at least partially sealed relative to humidity.

[0053] Said salted edible substances (A, A′) present an average salt value of 15 to 40 g per 100 g, preferentially an average salt value of 20 to 30 g, and an average sodium value smaller than 20 g per 100 g, preferentially an average sodium value smaller than 15 g per 100 g,

[0054] It is preferred when said salted edible substances (A, A′) differ in at least one of material shape, including of granulated type, of powder type, and colour.

[0055] It is preferred when said recipients (2, 2′) present a lid-like element adapted for closing the interior of the recipient (2, 2′) in sealed manner relative to humidity, a dosing disposition associated with the opening of the recipient (2, 2′) presenting at least one opening (21), or a grid of openings with a previously defined disposition, in a colourless transparent envelope.

[0056] In particular, said recipients (2, 2′) present an opening (21) adapted to the average dimension of particle of respective salted edible substances (A, A′). Moreover, said recipients (2, 2′) can present a single opening, or a grid of openings, for example of average dimension relatively smaller than in the case of a single opening.

[0057] Said salted edible substances (A, A′) comprise the species Salicornia ramosissima and can be used as substitute of salt in food in general, including in the preparation of cold and hot food. [0058] Lisbon, Feb. 18, 2020
