4. Conclusion
Due to the elevated monosaccharide concentration, the special
dairy products for elderly people presented high levels of furosine,
mainly in the case of samples subjected to a storage period at
ambient temperature. In addition, and as a result of lactose hydrolysis,
high levels of GOS were found. The results obtained in this
paper show the importance of controlling all processing conditions
during lactose hydrolysis, thermal treatment, and storage to
increase the level of prebiotic carbohydrates with low levels of lactose
and minimise the loss of lysine of dairy preparations designed
for elderly people. The information obtained here can be useful to
help in maintaining the health and well-being of this group of
population.
