Sažetak
Kale is a biennial herbaceous plant that is traditionally grown in the coastal area of Croatia. Microgreens have higher nutrient content compared to adult plants and can be produced in a short period of time. A two-factor experiment was set up to determine the influence of harvest time and load on yield, dry matter, total glucosinolates and phenolic content, total antioxidant capacity measured by DPPH, FRAP and ORAC, as well as on the sugar profile. Significantly higher yields were found in the later harvest dates, while, at the same time, the dry matter content decreased significantly. Prolonged load treatment showed a significant reduction in yield as well as a significant reduction in total phenolic content of microgreens. The bioactive potential of microgreens changed significantly with the harvest date, where early and medium harvests showed more total glucosinolates, higher antioxidant capacity measured by the FRAP method, and a higher amount of inulin compared to the late harvest. In addition to significantly higher yields, the late harvest also showed a significantly higher total phenolic content compared to earlier harvest dates. The determined nutritional parameters in the kale microgreens represent excellent potential for their valorization as a food product.
