Synergistic effect of fruit–seed mixed juice on inhibition of angiotensin I-converting enzyme and activation of NO production in EA.hy926 cellsCommonly consumed fruit juices possess low inhibitory activity of angiotensin I-converting enzyme (ACE), which plays central role in elevation of blood pressure. The ACE inhibitory activity of fruit–seed mixed juice may be improved via synergistic interactions. In this study, the investigated synergistic, additive, and antagonistic effects of fruit–seed combination on ACE inhibition were investigated. Thirteen fruits and 15 seeds including legumes, nuts, and cereals were combined in pairs; pear-hemp seed-pumpkin seed juice (3-mixed juice) displayed the highest ACE inhibition resulting from synergistic interactions. Additionally, nitric oxide production in human endothelial cells was promoted by 3-mixed juice. Three-mixed juice showed antioxidant activities such as DNA protective, DPPH radical scavenging, and reducing effects. These results suggested that combinations of different food categories are beneficial for improving biological functions such as vascular health. Three-mixed juice, which shows high ACE inhibitory activity, may be useful as an anti-hypertensive agent and for treating hypertension.

Studies on the physicochemical and biochemical characteristics in sesame seed juice under different roasting conditionsThe sesame seed juice contained abundant nutrients such as minerals, vitamins, and fatty acids. The contents of minerals, vitamin B1 and B3, and sesamol increased with increase in roasting temperature; however, the levels of fatty acids, vitamin B2, sesamin, and sesamolin decreased. In addition, the antioxidant content and antioxidative activities of sesame seed juice increased with increase in roasting temperature. Therefore, these results suggest that roasted sesame seed juice possesses high antioxidative activities, which may be beneficial for preventing oxidative damage in the body.

Mixed seeds juice with high antioxidant capacity and digestive enzyme activity and its applicationTo investigate the synergistic and combined effects of a seed–vegetable combination, oilseed crops (safflower seed, evening primrose seed, and sesame seed) and cereals (whole buckwheat grain) were extracted with carrot using a low-speed juice extractor. Nutrient composition showed that the mixed seeds juice provided a well-balanced diet to supplement nutrient deficiency. Four assays of antioxidant activities showed that all seed juices exhibited higher activities than carrot juice. Similarly, mixed seeds juice displayed the highest α-amylase and protease activities, implicating the formulation in the improvement of the relatively low digestibility of seed.
