Embodiment Construction

[0007] A method for producing high-purity fructo-oligosaccharides. The specific steps include: using sucrose as a raw material and converting and producing by an industrialized enzymatic method. The industrialized enzymatic production technology is an existing technology to obtain an ordinary grade oligomer with a content of about 55%. Fructose, the oligofructose also contains glucose and other by-products; then, using the principle of biological transformation, using yeast transformation to eliminate the glucose in the ordinary grade of oligofructose, so that the content of oligofructose can reach more than 75%; finally, the ion is reused Exchange chromatographic separation and membrane separation technology are combined to remove other components, so that the bottom fructose content in the product can reach more than 95%.

Abstract

The invention discloses a method for producing high purity of fructo oligosaccharides. The method comprises the steps of converting raw material of sucrose through enzymatic industrialized production to obtain ordinary grade fructo oligosaccharides with the content around 50 percent; then eliminating glucose in the ordinary grade fructo oligosaccharides by adopting the biotransformation principle and yeast transformation to make the content of the fructo oligosaccharides reach over 75 percent; and removing other composition by combining ion-exchange chromatography separation and membrane Separation technology to make the content of the fructo oligosaccharides reach over 95 percent. The method has the advantage that the production technology is reasonable and scientific, the fructo oligosaccharides with high purity can be extracted and industrial mass production can be realized.

Description

Technical field [0001] The invention relates to a method for producing health food, in particular to a method for producing high-purity fructooligosaccharides. Background technique [0002] Fructooligosaccharides (FOS for short), also known as fructo-oligosaccharides or fructotriose oligosaccharides, are obtained by using enzymes with fructose transfer activity in microorganisms to act on sucrose. It contains fructotriose, fructotetraose and sucrose. The products of fructopentaose have excellent health care functions and physiological characteristics. The specific characteristics are: 1. It can be selectively used by a type of bacteria (Bifidobacteria) in the human large intestine. After ingesting fructooligosaccharides, the number of Bifidobacteria in the human body will increase by 100 to 1000 times; 2. Not being used The human digestive tract is enzymatically hydrolyzed, so it is a low-calorie sugar; 3. It is a water-soluble dietary fiber that can lower blood lipids and improv...
