Abstract

The infrared spectra of melanoidins which were prepared from galactose and neutral and basic amino acids (at various ratios) support in general the conclusion gained in Part I of this series. A striking resemblance in the IR spectra was obtained in melanoidins which were prepared from a high ratio of sugar to amino acids (Type 1). The imprint of the amino acids was observed only in type 2 melanoidins, which are enriched with amino acids.
