Texture of dried blueberries was expressed as shear force and
ranged from 16.38 N to 33.15 N. The shear force is an indication of
the toughness of the product when consumed directly in the dry
state (Kim & Toledo, 1987). Among the four drying methods the
mean shear force values were lowest for blueberries produced in
the fluidized bed dryer (19.91 N), followed by those produced in the
forced air dryer (21.97 N), modified impingement dryer (22.06 N)
and impingement dryer (22.26 N), respectively.
