Effect of Wheatgrass Juice on Nutritional Quality of Apple, Carrot, Beet, Orange and Lemon Juice

Abstract

Fresh fruit and vegetable juices are commonly consumed as a valuable source of nutrients, while wheatgrass juice is, due to its nutritional value, used as a natural dietary supplement. The main aim of this research was to evaluate the effect of wheatgrass juice addition to apple, beet, carrot, orange, and lemon juice on total and in vitro bioaccessible concentrations of K, Ca, Mg, Mn, Fe, and Zn, vitamin C concentration, total phenolic and flavonoid content, and antioxidant activity. In comparison to other juices, wheatgrass juice had the highest total and in vitro bioaccessible concentrations of Ca, Mg, Mn, Fe, and Zn, while beet juice had the highest K concentration. Lemon and orange juices had the highest vitamin C concentration, while the highest total phenolic and flavonoid content were found in wheatgrass juice. After the addition of wheatgrass juice, Ca, Mg, Mn, and Zn concentration increased in all examined juices, vitamin C concentration increased in apple, beet, and carrot juice, total phenolic content increased in carrot juice, while total flavonoid content increased in apple, carrot, and orange juice. In comparison to the examined juices, wheatgrass juice has better nutritional value, and it could be used in a mixture with other juices to improve their nutritional value.

Component analysis and anti-pulmonary fibrosis effects of Rosa sterilis juice

“…We found that K was the most abundant macroelement in RSJ, and the levels were higher than those in pomegranate, orange, lemon, and carrot juice. 24,25 In addition, RSJ also contains Ca, Mg, Fe, and Mn, but its Na content is low; this composition characteristic may benefit some special populations, such as people who have hypokalemia, hypertension or arrhythmia. And a study has shown that Rosa roxburghii Tratt juice alleviated arsenic-induced element imbalance clinically, reduced the contents of Al, As and Cd, and increased the levels of Mn, Cr, Se and Sr in serum.…”

Variation in Nutritional Value of Diverse Wheat Genotypes

“…For cultivation, wheatgrass was used with Brill substrate (chemical composition of substrate: 80% white peat, 20% black peat; pH (CaCl 2 ): 5.5-6.0; Content of salt: 0.8-1.3 g L −1 ; nitrogen (N): 110-190 mg L −1 ; phosphorus (P 2 O 5 ): 140-230 mg L −1 ; potassium (K 2 O): 170-280 mg L −1 ). Cultivation and conditions for growing wheatgrass (duration of cultivation, temperature, and light regime) are described in [20]. The fresh wheatgrass juice was obtained by squeezing young wheatgrass leaves by hand with the Wheatgrass juicer BL-30 (Be Lih Do Enterprise Co., Ltd., Taoyuen, Taiwan).…”

“…Например, при добавлении в морковный фреш сока ростков пшеницы в напитке повышается концентрация химических элементов (кальция, магния, марганца, цинка), аскорбиновой кислоты, а также фенольных соединений. [24] Также сок моркови отлично сочетается по вкусу с яблочным, мандариновым, апельсиновым, тыквенным.…”
