“…There have been a few attempts to analyze flavonoid content in immature citrus fruits 10,23,24 , but no optimized method has been developed for recovering flavonoids from immature citrus fruits. To develop flavonoid-rich supplements using immature citrus fruits, the extraction method should be optimized for the highest recovery of index compounds.…”

Dietary guidelines recommend the consumption of flavonoid-rich extracts for several health benefits. Although immature Citrus unshiu pomace (ICUP) contains high levels of flavanone glycosides, many studies have concentrated on the optimization of flavonoid extraction from mature citrus peels. Therefore, we developed an optimized extraction method for hesperidin and narirutin from ICUP, and evaluated their antioxidant activities using ten different assay methods. The extraction conditions for the highest flavonoid yields based on a response surface methodology were 80.3 °C, 58.4% (ethanol concentration), 40 mL/g (solvent/feed), and 30 min, where the hesperidin and narirutin yields were 66.6% and 82.3%, respectively. The number of extractions was also optimized as two extraction steps, where the hesperidin and narirutin yields were 92.1% and 97.2%, respectively. Ethanol was more effective than methanol and acetone. The ethanol extract showed high scavenging activities against reactive oxygen species but relatively low scavenging activities for nitrogen radicals and reactive nitrogen species. The antioxidant activities showed a higher correlation with hesperidin content than narirutin content in the extracts. This study confirms the potential of an optimized method for producing antioxidant-rich extracts for the functional food and nutraceutical industries.

This study was carried out to investigate the physicochemical characteristics and antioxidant properties of mulberry juice (MJ) and mulberry vinegar (MV). MV, with acidity of 6.05% and a pH 3.06, was obtained from MJ after 8 days with alcohol fermentation and 20 days with acetic acid fermentation at 30℃. After fermentation, the major sugars in MV were lactose, glucose, and fructose, showing 1,310.06, 293.20, and 41.25 mg%, respectively. The major organic acids in MV were acetic acid (2,725.59 mg%), citric acid (524.66 mg%), and succinic acid (480.63 mg%). The total free amino acid content of MV, such as lysine, arginine, phenylalanine, and tyrosine, was 34.52 mg%. MJ and MV showed radical scavenging activities with respect to 1,1-diphenyl-2-picrylhydrazyl (DPPH), hydroxyl (OH), superoxide anion (O 2-), and nitric oxide (NO) radicals in dose-dependent manner, which were closely related to the total polyphenol and flavonoid contents in MJ and MV. In addition, a strong scavenging effect with regards to the OH radical was observed in MJ and MV, an IC 50 value of 0.04 μg/mL. In particular, MV showed a higher O 2 radical scavenging activity than that of MJ. These results suggest that MV can be used as a functional vinegar with antioxidant activity against free radicals.

The effects of premature mandarin powder (PMP) on the quality characteristics and antioxidant activities of scone were investigated. Scones were prepared by adding different concentrations (0, 0.625, 1.25, 2.5, and 5%) of PMP. As the content of PMP increased, density of dough slightly increased, while pH of dough decreased. The volume of scone increased with the amount of sample increased, but the group containing 5% PMP decreased. The moisture content and Hunter L value of scone were significantly decreased with increasing levels of PMP. On the other hand, sugar content and Hunter a value of scone were significantly increased with increasing levels of PMP. The Hunter b value of scone was shown to increase with increasing content of PMP while the group containing 5% PMP decreased. The texture analysis revealed that the hardness, cohesiveness, gumminess and chewiness of scone were decreased with the addition of PMP. The springiness showed no significant differences between control and PMP scones. Total polyphenolics, flavonoid content, DPPH and ABTS + radical scavenging activity, and reducing powder of scones significantly increased with PMP content. These results indicate that the addition of PMP to scone can improve its quality and antioxidant activities.
