| abstract |
The present invention provides a soybean oligosaccharide product comprising soybean acid soluble sugar and probiotics, wherein the soybean acid soluble sugar comprises fructose, glucose, sucrose, raffinose and stachyose, wherein raffinose and stachysine The weight of both sugars is 46% or more, fructose is 8.5% or less, and glucose is 1.0% or less, based on the weight of fructose, glucose, sucrose, raffinose and stachyose. The invention also provides a method for preparing a soybean oligosaccharide product, which comprises extracting a soybean raw material with water at pH 3-6 and a temperature of 50-70 ° C to obtain an extract of soybean-containing acid-soluble sugar, and inoculating the extract with a decomposable single The probiotics of sugar and disaccharide but not decomposing trisaccharide and tetrasaccharide are fermented. |
