“…Excessive levels of nitrites and, indirectly, nitrates in food, can pose a risk to human health. Increases in nitrate content have been observed in plants at early stages of development, with insufficient sunlight, acidic soil pH, low moisture, a lack of nutrients such as magnesium or molybdenum, and when herbicides are applied [5]. Vegetables such as parsley, lettuce, spinach, radishes, beetroot, celery and leek have the highest nitrate accumulation capacity [6].…”

Microgreens are a new, rapidly growing group of foodstuffs. The decorative function of these is often accompanied by their use in traditional dishes. As microgreens are eaten at very early stages, when the development of the epidermis is at its minimum, the bioavailability of minerals will be found to be higher in microgreens then in mature vegetables. So, microgreens can be an excellent functional food, especially for mineral-deficient populations, although they can also be a source of contaminants such as heavy metals or nitrates and nitrites. The purpose of this study was to measure the levels of selected heavy metals (i.e., cadmium, arsenic, lead, chromium, aluminium, zinc, copper, cobalt, molybdenum, manganese, vanadium, boron, antimony, thallium, titanium and strontium), as well as nitrates and nitrites, in microgreens at various stage of vegetation, using uncommon oilseed plants like nigella—Nigella sativa L., safflower—Carthamus tinctorius L., and camelina—Camelina sativa L. The examined microgreens of rare oilseed plants may be a source of contaminants and nitrates. The mineral profile of these plants is mainly determined by their genotype. Microgreens’ cultivation involves compliance with safety standards and replicable conditions to guarantee that the highest nutritional value is reached at the lowest possible contaminant level.

“…Our recent research [12] have shown that growing Brassicaceae microgreens under continuous lighting (24-h photoperiod) provided by LEDs resulted in higher yield and robast index (RI) compared to shorter photoperiod, and led to increased content of antioxidants (carotenoids, anthocyanins, flavonoids, proline, antioxidant enzymes). Moreover, it was shown that continuous LED lighting CL significantly decrease nitrate content in arugula, broccoli, mizuna and radish microgreens [13]. Control of nitrate content in microgreens is required as one of the main criteria for "functional foods" is its biological safety.…”

The work was aimed to examine the effect of mineral nutrition on yield and content of phytochemicals with antioxidative properties in radish (Raphanus sativus var. radicula) microgreens grown under different photoperiods (16 h and 24 h). Microgreens were supplied with mineralized water or 50% Hoagland nutrient solution. The study has revealed that robust index (RI, dry mass per unit of stem volume) was increased by the presence of mineral nutrition as expected. However, the relationship between the content of phytochemicals that determine nutritional value of radish microgreens and amount of nutrients in the growing media depended on what phytochemical was under consideration. Thus, plants supplied with Hoagland solution had higher chlorophyll and carotenoid content, while plants supplied with water had higher concentration of such antioxidants as anthocyanins and proline and lower nitrate content. Continuous lighting synergistically increased plant response to nutrient deficiency in terms of elevated anthocyanin and proline content and decreased nitrate content, while enhanced RI, chlorophyll and anthocyanin content in plants supplied with nutrient solution. Thus, microgreen productivity and nitrate content as well as some phytochemicals adding nutritional value to radish have opposite dependence on the level of plant nutrient supply, which suggests growers to make a choice between higher yield or higher health benefits to human health and consumer safety of radish microgreens.
