Studies on Shoyu-Manufacture by Paper Partition Chromatography.

II. Sugars in Syoyu (soy sauce)

Abstract

1. We ascertaind the existence of glucose, galactose, arabinose, and xylose in shoyu, but unfortunatly could not recognize ketose or ketose-containing sugars such as fructose and sucrose. The existence of maltose and manninotriose was vague.
2. We exathined the effect of NaCl, organic acids and amino acids on the Rf -value of sugars.
The NaCl was least desirable substance contained in syoyu in regard to the defection of sugars by this method.
