Starch and gluten are produced from wheat or smilar grain by a process comprising subjecting the grain, preferably in the form of flour, to extraction with water to give a starch fraction and a gluten fraction. According to the process, a poor quality starch fraction, obtained in addition to a pure starch fraction and a pure vital gluten fraction, is contacted with an aqueous alkali at a pH in the range for from 8.5 to 12.5. The thus treated fraction contains starch of sufficiently high quality to be used as the feedstock for conversion to lower polysaccharides or monosacchandes by, for example, enzymatic hydrolysis. |
