Nutritional value of wheatgrass juice – estimation on the basis of mineral concentrations

The aim of this research was to compare nutritional value of wheatgrass juice to apple, carrot, beet, lemon, orange, cabbage, Swiss chard and celery fresh juice on the basis of K, Ca, Mg, Mn, Fe and Zn concentrations. A concentration of elements in juices was determined by ICP – OES technique. According to one sample t test (p < 0.05) wheatgrass juice had significantly higher concentrations of all examined elements in comparison to apple, carrot, lemon, orange and cabbage juice. As hierarchical cluster analysis revealed, regarding the mineral concentrations, wheatgrass juice is most similar to Swiss chard and beet juice. Obtained results indicated that wheatgrass juice is valuable source of minerals. Therefore, it can be recommended for use in daily diet alongside commonly used juices.
