Because a high fat content in foods is associated with health disorders, consumers demand low fat
products, but without any loss of their texture quality. The instrumental texture and sensory properties
of biscuits in which 15 and 30 g/100 g of the fat has been replaced by two different carbohydrate-based
fat replacers (inulin and hydroxypropyl methylcellulose) were studied. The instrumental texture measurements
showed that inulin and hydroxypropyl methylcellulose (HPMC) biscuits were harder and the
sound emissions were higher than for the control biscuits. The trained sensory panel rated the biscuit
with 15 percent fat replacement by inulin as crisper than the control. The consumer study revealed that
fat replacement up to 15 g/100 g with inulin or HPMC provided acceptable biscuits, but higher
replacement decreased the overall acceptability.
