“…Owing to the crunchy texture and sweetness of carrots, it can be employed in some fruitlike roles. Choi et al (9) have demonstrated that carrot has the highest α-amylase activity among 12 different vegetables and fruits juice. From the above-mentioned nutritional viewpoint, carrot was chosen as the vegetable for increasing the digestibility, functionality, and palatability of seeds during seed juice preparation.…”

To 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. These results indicated that juice extraction significantly (<0.001) influenced the nutrient contents, antioxidant activities, and digestion enzyme activities of seed juice. The synergistic and combined interactions of seeds and vegetables may be beneficial in enhancing biological functions and result in a well-balanced diet.

Blueberry juice possesses rich-procyanidins andanthocyanidin, comprised a group of with numerous health benefits such as protection against coronary heart disease, detoxification, and obesity. Blueberry (Vaccinium virgatum) juice extracts were analyzed and separated by an HPLC method for the purpose of the separation and quantification in polyphenolic groups. In specific HPLC conditions, a binary mobile phase consisting of formic acid: water (10:90, v/v, solvent A) and formic acid: water: acetonitrile (10:60:30, v/v/v, solvent B) was utilized and it is detected at 546 nm wavelength. The phenolic contents of the extracts are determined using Folin-Ciocalteu phenol reagent. In order to test anti-inflammation activity assay, after producing nitric oxide (NO) in lipopolysaccharide activated RAW 264.7 cells, at concentration of 20-500 µg/mL it reduced to NO production at a dose-dependent manner. Importantly, cytotoxicity assay with up to 500 µg/mL of the extract from blueberry juice showed ~100% cell viability for RAW264.7 cell line. Therefore, Korean blueberry juice might have potential as anti-oxidant and antiinflammation agents.

This study aimed to compare the quality characteristics of pomegranate juice based on the extraction methods applied: centrifugal, single-gear, and twin-gear. Changes in the metabolic activities during digestion condition were further investigated. The twin-gear method was eventually identified as the optimal method, through comprehensive evaluation of the extraction rate, particle size, proximate composition, and the mineral and vitamin contents. Pomegranate juice derived using the twin-gear method had high-levels of bioactive substances such as phenolic compounds, flavonoids, anthocyanins, and selenium. Consequently, this juice exerted significant inhibitory effects on lipid peroxidation. Phenolic compounds are known to exhibit a high-correlation with skin-lightening, anti-aging, and anti-diabetic activities. An in vitro digestion model was used to evaluate changes in the antioxidant and angiotensin converting enzyme (ACE) inhibitory activities. Compared to levels observed before digestion, the results revealed a marked increase in the 2,2′azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging, ferric reducing antioxidant power, and superoxide dismutase-like activities as digestion progressed through the gastric phase condition, whereas most of these effects were stabilized or inhibited as digestion progressed through the intestinal phase. The ACE inhibitory activity was observed to increase after being subjected to gastric and intestinal digestion conditions. The correlation coefficients (r 2) for ACE inhibition and antioxidant activities were in the range 0.681∼0.952, thus indicating a highly positive correlation. The findings of this study indicate that the bioactivity of pomegranate juice is enhanced, as determined by the increase in various physiological activities as well as increase in the bioaccessibility and bioavailability of bioactive substances during digestion.
