“…Anthocyanin is known to have physiological functions, as it has antioxidative activities, contributes to the prevention of arterial sclerosis, and is a type of functional food. Furthermore, anthocyanins in purple-fleshed sweet potato are known to have physiological functions, such as antioxidant properties (Furuta et al, 1998), antimutagenicity (Yoshimoto et al, 1999), and the ability to provide relief from liver injury (Suda et al, 1997). reported that the quality, in terms of both aroma and taste, of purple rice wine made with uncooked, unpolished purple rice was much higher than that of rice wine made with cooked, unpolished purple rice.…”

Alcoholic beverages made from purple rice grains contained 11.0 to 11.5% (v/v) ethanol and a higher amount of phenolic compounds. Alcoholic beverages made from purple rice grain were brilliant red, similar to the color of red wine, especially those made from uncooked purple rice. The amount of anthocyanin in beverages made from cooked and uncooked rice was 36 and 88 μg/mL, respectively. The DPPH radical scavenging activity of the alcoholic beverages made from purple rice was much higher than that of beverages made from ordinary brown and polished rice. The lipid peroxidation inhibitory activity of the alcoholic beverage made from uncooked purple rice was also the strongest. In the course of this study, we produced purple rice wine that was red and exhibited antioxidative activity.

“…Anthocyanins are widely used as natural food colorants, and have been reported to have functional effects, such as antioxidant (Tsuda et al, 1998;Noda et al, 1998) antitumor (Koide et al, 1996;Koide et al, 1997), antimutagenicity (Yoshimoto et al, 1999), and others (Tsuda et al, 1999); they are also expected to be functional food ingredients. Research on production of secondary plant metabolites by plant cell and tissue cultures is increasing to find an effective system, or as one aspect of food biotechnology (Koda et al, 1992;Koda et al, 1993;Nawa & Ohtani, 1992).…”

Cultured leaf cells of Nyoho strawberry (Fragaria ananassa Duch.) produced 4 times more anthocyanins than fruit, with additions of 2.0 mg/l of 1-naphthalenacetic acid (NAA) and 0.2 mg/l of benzyladenine (BA) for 2 weeks. They were habituated after 6 passages at NAA 1.25 and BA 0.125 g/l in 107 cultures with stepwise decrease of the additions at 2-week intervals, and supervention of a gradual decrease in anthocyanin contents of 80%. They fully recovered through the following 43 passages without the additions. Finally, 3 types of cell line rich in cyanidin 3-glucoside (62%), peonidin 3-glucoside (55%) or both (49 and 36%, respectively) were obtained. They also produced pelargonidin 3-glucoside (0.6 to 1.8%), which was the main component in the fruit. The fruit produced peonidin 3-glucoside (0.4%), as well as pelargonidin 3-O-(6-O-malonyl-␤-D-glucoside) and cyanidin 3-glucoside. The habituation seems to have caused some activation or inhibition of the cell's anthocyanin formation, which originated from the mother plant.
