The content of the chloroplast pigments, phenols and vitamin C in the juice and the cellulose residue of the wheatgrass (Triticum aestivum L.)

It is known that wheatgrass is a rich source of nutrients that have a positive impact on human health. Making the juice of it using juicer, the cellulose residue is most often thrown away. The aim of the study was to determine the content of photosynthetic pigments, phenols and vitamin C in the juice and the cellulose residue in ten varieties of wheatgrass and evaluate the amount of active components remaining in the cellulose residue. On average for all varieties, significantly higher amounts of these compounds were found in the cellulose residue as compared to the juice. There was also significant difference in the content of the before mentioned compounds between wheat varieties. The highest average content of chlorophyll a, carotenoids and phenols was found in Katarina variety, the highest content of chlorophyll b in the variety Eurofit and the highest content of vitamin C in the variety Pipi. The data obtained show that the variety significantly affects all of the examined parameters and that more than half of the biologically active compounds tested are lost by throwing the cellulose residue.
