Conclusions
Egg yolk derivatives have shown to be a key ingredient for
the development of these new snack products. Furthermore,
according to data obtained in this work, it has been proved that
the use of yolk derivatives improved not only the organoleptic
characteristics of the snacks, but also its mechanical properties
and nutritional profile. In fact, although in sensory evaluation,
all base products were favourably assessed, it is important to
remark that granule snacks obtained the highest score. Additionally,
some potential applications of these base products,
such as edible recipients or fried snacks, have been successfully
assayed as examples.
To sum up, it should be pointed out that, after years of
utilization in food field, this study expands the use of yolk,
showing this raw material still as a suitable ingredient for
culinary experimentation.
