Abstract
Plant breeders and tofu processors need to understand the influence of
environment on tofu quality and color. Our objective was to determine the
influence of locations within a year and differences between years on tofu
yield, quality, and color. We evaluated two soybean (Glycine max (L).
Merr.) genotypes that were developed for the tofu specialty market at four
locations in 1993 and five locations in 1994. There were significant
differences between years for tofu yield, protein content, oil content, and
color averaged across genotypes. There were significant differences among
locations within each year for soymilk solid content and tofu yield,
protein content, oil content, protein ratio (11S/7S), firmness,and
yellowness. Due to the influence of environment, genotypes should only be
compared for tofu yield, quality, and color within the same environment.
Processors can use this information to identify which locations produce the
best quality tofu. This article is only available online at
