Wild halophytes are traditionally consumed in Tunisia as gourmet vegetables due to their salty taste and organoleptic
proprieties. However, their nutritional composition is not deeply studied. The aim of this study was to
characterize three Tunisian wild halophytic species (Arthrocnemum indicum (Willd.) Moq, Halocnemum strobilaceum
(Pall.) M. Bieb., and Suaeda fruticosa Forssk) at two different phenotypic stages according to the seasonal
variation. Amaranthaceae, is one of the well spread halophytes family shrubs in the world, mainly in
Mediterranean countries. The studied wild halophytes are an interesting source of nutrients and could be considered
as healthy foods with high levels of dietary fibers (7.63–10.14 g/100 g fw), protein (2.45–4.14 g/100 g
fw), n-3 polyunsaturated fatty acids in green phenotypic stage (29.87 %–40.5 %) and n-6 polyunsaturated fatty
acids in red-violet phenotypic stage (25.4 %–75.26 %), with particular relevance to linolenic acid content (20.7
%–75.22 %). These halophytes are also a good source of minerals, particularly sodium, calcium, potassium and
magnesium, as well as vitamins C and E, with a major abundance of α-tocopherol.
