Stachyose

 

a nonreducing reserve carbohydrate (tetrasac-charide) of plants, consisting of two galactose radicals, a glucose radical, and a fructose radical. First isolated in 1890 from the rhizome of the woundwort Stachys tuberifera, it has been found in more than 100 species of plants, including representatives of the families Leguminosae, Rosaceae, and Labiatae. Soybean meal and unrefined beet sugar are also good sources of stachyose. In carbohydrate metabolism within plant cells, stachyose serves as both a donor and accepter of the galactosyl radical.

Therefore, Catucai showed the higher absolute values and significant increases after the three cycles at 13/4[degrees]C (except for stachyose after chilling exposure) of the soluble sugars related with osmotic regulation and membrane stabilization and protection (MORSY et al.

These three waste sugars - raffinose, stachyose, and verbascose - account for up to 6 percent of the weight of the soybeans, says Kuo.
The report focuses on eleven commercial categories of functional oligosaccharides in China, including isomalto-oligosaccharide, fructo-oligosaccharide, xylo-oligosaccharide, galacto oligosaccharide, stachyose, raffinose, soy-oligosaccharide, isomaltulose, chitosan-oligosaccharide, trehalose, and malto-oligosaccharide.
Fermentation with fungi also successfully reduces the amount of stachyose and raffinose in SBM which contains approximately 52 g/kg stchyose and 11 g/kg raffinose (Cervantes-Pahm and Stein, 2010).
Researchers were able to reduce the levels of flatulence-causing stachyose and raffinose by 92% and 80% by germinating the soybeans in the presence of R.
