Soy Sauce Production Utilizing Root Crop Flour As Substitute For Wheat Flour (100% Substitution)
Emma S. Data | Julie C. Diamante | Edna E. Forio
Abstract:
Soy sauce yield was not affected by the substitution of wheat flour with
root crop flour as carbohydrate source for the fermentation micr?organisms. The titratable acidity, pH and NaCl content were not signifi.
cantly affected by flour substitution while the protein content and amino
nitrogen of root crop-based soy sauce were lower than that of sauce
produced from wheat flour.
Sensory evaluation showed that when soy sauce was used in preparing
beef steak or as dip for broiled fish, root crop-based soy sauce was
comparable to one commercial brand based on general acceptability scores.
Cooked sweet potato-based soy sauce was comparable to two commercial
brands when served as pure soy sauce based on color, aroma, consistency
and flavor.
