The phytochemical composition of carotenoids, tocopherols, free sugars, organic acids, L-ascorbic acid, capsaicinoids, and flavonoids in green and red paprika (GP and RP), and paprika leaves (PL) cultivated in Korea were analyzed. The ethanolic extracts of GP, RP, and PL were obtained with 80% ethanol, and their antioxidative activities were determined by measuring their ABTS and DPPH radical scavenging activities. RP showed the highest contents of capsanthin (58.33 ± 3.91 mg/100 g dry weight) and L-ascorbic acid (1987.25 ± 19.64 mg/100 g dry weight), and main compounds of PL were lutein, chlorophyll, and γ-tocopherol (96.91 ± 14.58, 2136.71 ± 21.11, and 723.49 ± 54.10 mg/100 g dry weight, respectively). RP showed the strongest antioxidant activity (IC= 55.23 ± 6.77 μg/mL in a 2, 2′-azino-di-[3-ethylbenzthiazoline sulphonate] assay and 150.40 ± 8.07 μg/mL in a 2, 2-diphenyl-2-picrylhydrazyl assay), and the antioxidant activity of PL was higher than β-carotene but lower than RP. The results indicate that the amounts of capsanthin and L-ascorbic acid in RP correlate well with antioxidant activity. PL, which has various phytochemicals such as lutein, chlorophyll, and γ-tocopherol, might be used in nutraceuticals and pharmaceuticals for improving human health. [ABSTRACT FROM AUTHOR]

In this study we investigated the production of vinegar using a Hericium erinaceus fermentation. After 9 days of alcoholic fermentation, the alcohol contents reached 16% with all concentrations (1.25%, 2.5% and 5.0%) of H. erinaceus powder investigated, whereas the sugar content decreased from 25 °Brix to 14 °Brix. Also, the broth pH decreased from 4 to 3.7 and the acidity increased from 0% to 0.3%. According to the sensory evaluation, the mushroom wine produced with 5.0% H. erinaceus powder was preferred by the panel, which was then chosen for subsequent acetic acid fermentation. During the acetic acid fermentation, there was little change in pH, even though the acidity increased from 2% to 4.09%. Besides the abundant acetic acid present in the H. erinaceus vinegar, malic acid and succinic acid were also detected after 9-day of fermentation. Moreover, the H. erinaceus vinegar showed antioxidant activity comparable to other vinegar products when assayed by DPPH and ABTS. [ABSTRACT FROM AUTHOR]
