1 Scope

This standard stipulates the determination of three kinds of oligofructose, such as infant formula rice flour, rice milk powder and low-poly cane fruit trisaccharide, tetrasaccharide and pentasaccharide in milk powder. Method. This standard is applicable to the determination of low poly cane fruit trisaccharide, tetrasaccharide and pentasaccharide in infant formula rice flour, rice milk powder and milk powder.

2 Normative references

The following documents are indispensable for the application of this document. For dated references, only dated versions apply to this article. Pieces.

3 Method summary

After precipitation of protein and starch by precipitation of acetic acid water and methanol solution at a given pH, the oligofructose in the sample is then treated with β-galactosidase. Remove galactose and lactose, pass the membrane test, and quantify by external standard method.
