ABSTRACT:
A method and apparatus for determining the pasting temperature of starch and the like is disclosed wherein a quantity of starch granules are mixed to form a slurry which is heated while a light source is passed through the slurry. Photosensor means detect the light transmittance through the slurry and are connected in circuit to place a visual temperature display means in a hold condition displaying a temperature representative of the pasting temperature of the starch when the light transmittance reaches a predetermined threshold.
