Abstract
The rate of Maillard browning in ethanolic solutions of glucose－glycine
increased with an increase in ethanol concentration. The rate of browning in 0－50%
ethanolic solutions of glucose－glycine is higher at pH 5.5 than at 4.3. The
descending order in browning potential in 50% ethanolic solution of sugar－glycine
buffered at pH 4.3 is xylose, galactose, glucose, fructose, lactulose and sucrose among
sugars; and that in 50% ethanolic solution of glucose－amino acid at pH 4.3 is lysine,
threonine, serine, glycine, cysteine and alanine among amino acids. Ethanol inhibits
hydroxymethylfurfural (HMF) formation in glucose solution. Glycine accelerates
HMF formation and browning in glucose－glycine solution. The acceleration effect is
enahnced by ethanol.
Subjects
Maillard, browning, ethanol, hydroxymethylfurfural.
