Hydroxymethylfurfural as an indicator for the detection of dried powder in liquid milk.

摘要

Detection of dried milk in liquid milk is based on the determination of HMF values. The HMF content in raw unheated milk was 7.66μmol/litre and in pasteurized and UHT milk, respectively, it ranged from 10.52-16.0 to 16.33-20.85μmole/litre. HMF indried milk reconstituted to liquid milk with 9% SNF was 28.0μmole/litre. It is concluded that these HMF values can be used to detect adulteration of raw, pasteurized and UHT liquid milk with dried milk.
