Rice bran fiber has fructo-oligosaccharides - a pre-biotic that helps friendly bacteria to proliferate in the gastrointestinal environment and improves intestinal and colon health (Tomlin and Read, 1988). Recent studies in humans (Kahlon and Chow, 1997) have revealed that rice bran fiber not only normalizes bowel function, but also helps in conditions such as irritable bowel syndrome (IBS), inflammatory bowel disease (IBD) and Crohn s disease, and lowers the lipid levels. Rice bran fiber has been shown to significantly reduce renal stones (Jahnen et al., 1992). It is a good source of fiber in weight loss programs and therapeutic fiber diets for diabetics and heart patients. Fiber diets prevent cancer of the colon and large bowel, control obesity and improve bowel function.

The decomposition of 1-kestose is a key step in the production of fructo-oligosaccharides, which are found in many health foods because of their noncaloric and noncariogenic nature. 

Phenomenological chiral discrimination of various permethylated linear oligosaccharides toward organic amines has been examined by using the FAB-MS-EL guest method." " " As shown in Table 15, permethylated fructo-oligosaccharides, especially the permethylated 1 -fructonystose (MeFruNys in Scheme 8), display a remarkable chiral discrimination ability." If compared to linear...
