Sažetak
The goal of our study was to evaluate the effect of high (HT: 38°C day/33°C night) and regular (RT: 23°C day/18°C night) growing temperature on the bioavailability of total glucosinolates and phenolics from broccoli (Brassica oleracea L. convar. botrytis (L.) Alef. var. cymosa Duch) sprouts upon final, intestinal, phase of in vitro simulated human digestion. The extracts were prepared from freeze-dried plant material using boiling (100°C) water followed by incubation on rotary extractor for 1 hour at 23°C. The results showed that HT negatively affected the intestinal bioavailability of total glucosinolates from broccoli sprouts, i.e. their concentration was decreased to 47 % of the initial concentration (non-digested extract). On the other hand, RT did not change the bioavailability of total glucosinolates significantly (p≤0.05). Total phenolics bioavailability was not affected neither by HT, nor by RT condition ; in both cases it was very high (>90 %). These results show that glucosinolates of broccoli sprouts are significantly more susceptible to HT than total phenolics, and suggests future more detailed analyses of Brassicaceae microgreens phytochemical temperature susceptibility/resistance.
