Near-infrared spectrophotometry (NIRS) methods were used
to screen 832 samples of soybeans for oligosaccharides and nonstarch
polysaccharides. They suggested that NIRS is a suitable and rapid nondestructive
method to determine carbohydrate (stachyose, raffinose, sucrose, maltose,
glucose xylose, fructose maltose, nonstarch polysaccharides and uronic
acid). Among the raffinose group of oligosaccharides, stachyose was
predominant in the soybean samples analyzed. They found significant
differences in the most low-molecular-weight carbohydrates in the soybean
lines analyzed; the exception was fructose. The authors believe that
they have demonstrated that high-resolution NIRS has the potential to
identify heat-stable antinutritional (nonstarch polysaccharides and
oligosaccharides) in soybeans and these methods can be used to improve
the utilization of soybean meal in diets for some monogastic species.
