This positive effect was also confirmed
in a sensory evaluation by a professional
taste panel. In a blind triangle test, 12
out of 18 trained panelists preferred almond
milk that was produced with the
addition of alpha-cyclodextrin. While the
standard almond milk was described as
watery, lacking in body, nutlike, bitter and
astringent, the almond milk containing
alpha-cyclodextrin was characterized as
having more body, less bitterness, an improved
creaminess and a better mouthfeel.
Cyclodextrins are known for their potential
to mask undesired flavors in different
matrices. As part of this study, it was
shown that alpha-cyclodextrin can also
balance the cooking off-taste of high
temperature treated milk and cover rancid
off-notes of vegetable fat fractions in
non-dairy powder formulations.

Cyclodextrins
Cyclodextrins are carbohydrates
that WACKER
manufactures from plant
starch. They are characterized
by their cyclic threedimensional
structure with
a hydrophobic cavity. This
cavity can interact with lipophilic
molecules. The hydrophilic
outer surface in
turn ensures compatibility
with aqueous systems. This
special structure exhibited
by cyclodextrins opens up a
wide range of functionalities
and applications.
Depending on the size of the ring, a distinction is made between alpha-cyclodextrin
with six, beta-cyclodextrin with seven and gamma-cyclodextrin
with eight glucose units. WACKER is the only company in the world to manufacture
all three naturally occurring cyclodextrins. They are marketed under
the following trade names: CAVAMAX W6 (α-cyclodextrin), CAVAMAX
W7 (β-cyclodextrin) and CAVAMAX W8 (γ-cyclodextrin).
