Oligomeric galactose (GOS) is the oligosaccharides of 1-4 galactosyl on the galactosyl side of lactose molecule connects.The foundation of infant's intestinal microflora relies on the oligomeric galactose component in breast milk to a great extent.The oligomeric galactose not still multiplicaiton factor of bifidus bacillus in enteron aisle, also has and improves metabolism of fat, promotes the effects such as calcium absorption.Oligomeric galactose product on current domestic and international market is substantially all with biological enzyme synthesis, and product oligomeric sugar (oligomeric trisaccharide, tetrose and pentasaccharides) content is 24% ~ 57%, also there is the lactose of a great deal of, glucose and a small amount of semi-lactosi.The existence of small molecular sugar greatly reduces the physiological function of oligomeric galactose.Therefore, oligomeric galactose product is purified there is very high economic worth and significance of scientific research.
The method of oligose separating-purifying mainly contains enzyme process, microbe fermentation method, chromatographic column partition method and membrane separation process.The former two consumes small molecular sugar by biotechnology, but reaction may introduce other much new materials, and complicated operation, cost are high.Column chromatography method needs a large amount of eluents, and separation cycle is long, the energy that product needs vacuum-evaporation and at substantial because concentration is low.And the advantage such as membrane separation technique has simple and compact device, high and energy expenditure is low without phase transformation and chemical reaction, selectivity, therefore can adopt membrane technique separation and purification or concentrated various oligosaccharide solution.
Film is the material with selective separation function.According to the performance of ultra-filtration membrane, the material of ultra-filtration membrane can be divided into macromolecular material and the large class of inorganic materials two.Macromolecular material mainly contains cellulose family, poly-maple class, polyamide-based, polyolefine, fluorinated etc.; Inorganic materials mainly contains pottery, metal, glass, molecular sieve etc.The aperture of film is generally micron order, according to the difference (or aperture) of its molecular weight cut-off, film can be divided into microfiltration membrane, ultra-filtration membrane, nanofiltration membrane and reverse osmosis membrane.Ultrafiltration membrane technique both can remove disease caused by infectious water bacterium, virus, thermal source, colloid, etc. objectionable impurities, can to dialyse again inorganic salt, be widely used in milk separation, concentration of juices, yellow rice wine purifying, aging of white wine, beer sterilization, monosodium glutamate purified, the decolouring of sugarcane chaff, amino acid is concentrated, soy sauce is degerming etc. produces, but also be widely used in medical injection water, preparation that transfusion water, bottle-washing water, surgical operation wash clean water.
