Inulin is highly studied and has already been accepted
as a prebiotic. Due to its recognized prebiotic properties, it is increasingly used in the development of new
food products. Often different types of biscuits do not
have a prebiotic effect, but by adding ingredients such
as inulin, their biological value can be increased.
In order to determine the characteristics of the biscuits
with inulin two types of biscuits were produced: control
(regular) biscuits and biscuits prepared with inulin. The
raw materials used include: integral rye flour, buckwheat
flour, oat flakes, flaxseed, sucrose, salt, sodium bicarbonate, cinnamon, sesame seed, water, olive oil and inulin.
The biscuits production includes the following operations: measuring raw materials, mixing the powdery
raw materials, adding water and oil, stirring, resting the
dough in a refrigerator for 15 min., rolling out the dough
and forming the biscuits, baking (150 0
С, 10 min.), cooling at room temperature and packing. The prepared
biscuits were chemically analyzed: moisture (routine
reference method), ash (MKC EN ISO 2171:2011), protein
(МКS EN ISO 20483-1:2011), fat (МКС EN ISO 6492:2012),
crude fiber (MKC EN ISO 6865:2010), nitrogen-free extract (calculated by difference) and energy value (by calculation using Atwater factors). Also, the biscuits were
sensory analyzed. Sensory analysis was conducted by
applying the scoring method.
The addition of inulin increased the content of moisture (11.18%), proteins (11.35%) and nitrogen-free extract in the biscuits. (58.61%), and reduced the content
of ash (1.84%), fat (14.69%) and crude fiber (2.35%). Inulin biscuits had a lower energy value and a received a
higher average total sensory grade (14.19) in comparison with the regular biscuits (13.55).
From the results obtained it can be concluded that
adding inulin to the biscuits influences by decreasing
the energy value of the biscuits and improving the sensory characteristics.
Key words: Biscuits, Functional food, Inulin, characteristics.
