To provide a method for separating and collecting tapioca starch efficiently from cassava roots and an industrially advantageous method for producing amino acids by fermenting the tapioca starch as the starting material.
A tapioca starch manufacturing method is presented, in which cassava roots are crushed in a conventional starch collecting process into 1-10 mm diameter grains, and then ground mechanically into 50 mesh passable granules or subjected to a cellulase-aided enzymatic process after being ground mechanically. Trash is removed from the starch suspension, and starch is finally collected from the starch suspension. An amino acid producing method by fermentation is also presented, in which the thus collected tapioca starch is treated with a starch liquefying enzyme and with saccharogenic amylase for development into a high-concentration saccharide solution usable as the material for an amino acid producing fermentation process.
