Sažetak
In the last years there is a growing demand for fresh and healthy food, and sprouts are an example of recognized nutritional value. Moreover, the improvement of the foods nutritional quality has become a general health concern. The practical advantage and convenience that the sprouts offer to the consumers makes this market currently the fastest growing sector in food industry. One simple strategy to improve the nutritional properties of microgreens could be the interspecific transfer of bioactive compounds. Therefore, our goal was to analyze the potential of interspecific source-sink phytochemical transfer for the improvement of phenolic bioactive compounds and vitamin C profile in microgreens, their gastrointestinal bioaccessibility, hypoglycemic potential, and antioxidant capacity as well as antiproliferative effect. In addition, we also tested whether an effect of phytochemical transfer is evident in the expression of marker genes in phenolic biosynthetic pathways. Chinese cabbage (Brassica rapa ssp. pekinensis) was used as a model organism. The results showed that interspecific phytochemical transfer from donor Tamus communis extract significantly improved bioaccessibility of vitamin C, kaempferol and total phenolics both before and after gastrointestinal digestion of Chinese cabbage microgreens, increased their hypoglycemic activity, and antioxidant capacity. In addition, sprouts treated with extracts from Rosa sp. and H. perforatum showed better cytotoxicity towards human breast adenocarcinoma cells than untreated sprouts. qRT-PCR analyses revealed that BrpFLS of Chinese cabbage microgreens was slightly upregulated upon a 4-hour treatement with Rosa sp. extract, therefore, this gene could be used as a marker for the biosynthetic pathway alteration. All together, the results suggest that treatment with donor extracts can be considered a promising approach to improve the nutritional properties of Chinese cabbage sprouts as „healthy food“.
