Study on Soybean Oligosaccharides Refining Process
Abstract:
Soybean concentration proteins were extracted from defatted soybean meals with ethanol agent method. Crude soybean oligosaccharides were gained after recovery the alcohol by concentration with the soybean whey water as row material. Then a series of purification process such as precipitating proteins, desalting with ion exchange and decolorizing carbon were used to obtain soybean oligosaccharides end product. The soybean oligosaccharides refining process technique and parameters were presented in this paper and could be applied to large-scale industrial production. Physical chemical quality index of soybean oligosaccharides after refining was that concentration was 70%, total sugar purity was no less than 85%, protein content was 1.3% (dry base content), ash content was 0.73% (dry base content).
