“…These authors, in the compendium on the nutritional potential of quinoa, refer to values in seeds for the elements calcium (275-1487 mg/kg), copper (10-95 mg/kg), iron (14-167 mg/kg), magnesium (260-502 mg/kg), phosphorus (1400-5300 mg/kg), potassium (6967-14,750 mg/kg), sodium (110-310 mg/kg), and zinc (28-48 mg/kg). The mineral composition values (P, K, Ca, Mg, Fe, Na, and Zn) analyzed in different cultivars of C. quinoa by Reguera et al [68] and Rodríguez et al [69] also follow the frequently reported concentrations for this species.…”

(1) Background: This study provides novel insights into the elemental content and biomineralization processes of two halophytic species of the genus Arthrocnemum Moq. (A. macrostachyum and A. meridionale). (2) Methods: Elemental content was analyzed using ICP-MS, while biominerals were detected through electron microscopy (SEM and TEM) and X-ray diffraction. (3) Results: The elemental content showed significant concentrations of macronutrients (sodium, potassium, magnesium, and calcium) and micronutrients, especially iron. Iron was consistently found as ferritin in A. macrostachyum chloroplasts. Notably, A. macrostachyum populations from the Center of the Iberian Peninsula exhibited exceptionally high magnesium content, with values that exceeded 40,000 mg/kg d.w. Succulent stems showed elemental content consistent with the minerals identified through X-ray diffraction analysis (halite, sylvite, natroxalate, and glushinskite). Seed analysis revealed elevated levels of macro- and micronutrients and the absence of heavy metals. Additionally, the presence of reduced sodium chloride crystals in the seed edges suggested a mechanism to mitigate potential sodium toxicity. (4) Conclusions: These findings highlight the potential of Arthrocnemum species as emerging edible halophytes with nutritional properties, particularly in Western European Mediterranean territories and North Africa. They offer promising prospects for biosaline agriculture and biotechnology applications.

“…In these three ‘grain’ species, the nutritional quality of both leaves and seeds is high. Seeds are rich in proteins, more than most true cereals, and minerals [ 54 , 55 ], while leaves are also rich in proteins, minerals and vitamins [ 56 , 57 , 58 ]. Grain amaranth can produce seed yields of 2000–3500 kg·ha −1 [ 59 ], whereas leaf amaranth can produce several dozens of tons per hectare of fresh leaves and young stems eaten as vegetables [ 60 ].…”

Amaranths (Amaranthus L.) are multi-use crop species renowned for their nutritional quality and their tolerance to biotic and abiotic stresses. Since the soil salinity of croplands is a growing problem worldwide, we tested the salinity tolerance of six grain and two leaf cultivars of Amaranthus cruentus L. The plants were grown for 53 days under hydroponic conditions at 0, 50 and 100 mM NaCl. We investigated the growth rate, photosynthetic activity, mineral content, pigments and biochemical compounds involved in oxidative stress. Although 100 mM NaCl always decreased biomass production, we highlighted Don Leon and K91 as tolerant cultivars under moderate salt stress (50 mM NaCl). Under salinity, sodium accumulated more in the shoots than in the roots, particularly in the stems. Sodium accumulation in the plants decreased the net photosynthetic rate, transpiration rate and stomatal conductance but increased water use efficiency, and it decreased chlorophyll, betalain and polyphenol content in the leaves. It also decreased the foliar content of calcium, magnesium and potassium but not the iron and zinc content. The physiological parameters responded differently to sodium accumulation depending on the cultivar, suggesting a different relative importance of ionic and osmotic phases of salt stress among cultivars. Our results allowed us to identify the morpho-physiological traits of the cultivars with different salt tolerance levels.

“…Therefore, the storage of quinoa bran needs to be moisture-proof treatment. The average energy of quinoa bran was 360.2 kcal/100 g, which was slightly higher than that of quinoa grain (315.2–355 kcal/100 g) ( Gómez et al, 2021 , 2023 ). This may be due to the high content of protein, fat and fiber in quinoa bran.…”

“…The total carbohydrate content of quinoa bran was calculated by subtracting the percent content of protein, fat, crude fiber, ash content and moisture from 100. Energy value was estimated based on the contents of fat, protein, total carbohydrate and crude fiber using the Atwater factors of 9.0, 4.0, 4.0 and 2.0 kCal/g of each component, respectively ( Thakur et al, 2021 ; Gómez et al, 2021 , 2023 ). The results are expressed as kCal 100 g −1 fresh weight.…”
