Maillard reaction (non-enzymatic browning) formed during heat treatment is an important
for the quality of foods. Hydroxymethylfurfural (HMF) is an intermediate
compound of this reaction and can be changed with temperature during production
and storage in dairy products. In this study, the HMF levels of pasteurized and
UHT milks with different fat contents were determined. In addition to the
effect of hydrolisation of lactose on HMF contents, the composition and colour
values of milk samples were also determined. Total HMF values varied from 1.15 to 4.78 µmol/L
in pasteurized milk, 2.16 to
12.74 µmol/L in UHT milk and 27.35 to 35.73 µmol/L in lactose hydrolised milk. Although
increase in heat process resulted in an increase in HMF values, levels were
still lower than those in other food products. HMF values of UHT milk slightly
increased with an increase in milk fat. The highest level was obtained in lactose
hydrolised UHT milk. Moreover, the redness values of lactose hydrolised UHT
milks were high.
