Stachyose utilization

In 1913, Tanret concluded that stachyose (in translation) is well utilized by man. Experimenting on myself, I made a meal of 500 g. of the artichokes, i.e., Stachys tuberifera rhizomes, both the bulbs themselves and the cooking water, containing at least 25 g. of stachyose. When the urine was examined afterward, it did not show the least optical rotation. 36 No other effects were reported by Tanret. Although Stachys tuberifera is cultivated for human food in scattered parts of the world, it is extremely unlikely that the stachyose which makes up the bulk of its dry weight is of any direct food value. 

The unusual utility of this adsorbent has been demonstrated by its role in the preliminary isolation of isomaltose,maltotriose, maltotetra-086, = and panose > from the hydrolytic products of starch in the preparation of n-xylo-biose, -trio.se, -tetraose, -pentaose, -hexaose, and -heptaose from a partially hydrolyzed xylan in the resolution of bi-molecular dianhydrides of L-sorbose < and D-fructose < > in an improved procedure for the preparation of stachyose and in the preparation of a series of maltodextrins (as high as maltoheptaose) from the partial, acid...
