Effect of Papain on Amylograph Viscosity of Flour.

Additions of small amounts of the proteolytic enzyme papain lowers the peak viscosity of a flour-water slurry as measured on the amylograph. This effect was found to be due to release or activation of beta- amylase which is inactive under normal conditions used for the amylograph test. The magnitude of this effect is different for different flours.
