“…Since then, many attempts have been made to develop a method for its production from rice germ (Ohtsubo et al, 2000), brown rice (Kinefuchi et al, 1999), wheat germ (Takigawa et al, 2009), and wheat bran (Nogata and Nagamine, 2009). In addition, fortification methods by fermentation have been reported (Yokoyama et al, 2002;Kono and Himeno, 2000;Aoki et al, 2003). With respect to the physiological effects of proteinaceous amino acids, leucine (Leu), glutamine (Gln), and arginine (Arg) have been reported to promote protein synthesis (Buse and Reid, 1975;Rennie et al, 1986;Elman, 1988).…”
