Hydrolysis of Starch Grains by Polarized Infra-Red Radiation

  title={Hydrolysis of Starch Grains by Polarized Infra-Red Radiation},
  author={E. S. Semmens},
AT the Liverpool meeting of the British Association in 1923, it was shown that polarized radiation had the effect of accelerating the change of starch grains, in a weak suspension of diastase and at ordinary laboratory temperature, into a crystalline reducing substance; but if the diastase were active or concentrated, no selective effect was observed1. Earlier experiments in 1922 had shown me that, when ground cereals in plain tap water were exposed to this radiation, a portion of the starch… Expand

Nonconventional methods of modification of starch.
This chapter presents the nonconventional methods for the modification of starch and suggests that the effect of irradiation on starch gels is generally monitored by the changes in viscosity, reducing power, and reaction with iodine. Expand

Water Snails and Liver Flukes
It is shown that the snail L. peregra, which is extremely common in all sorts of ditches, puddles, and streams, constitutes no impediment, therefore, to this snail acting as a disseminator of the liver-rot parasite granted that it can become properly infected. Expand
