The fresh Sarawak pineapples (Ananas comosus)
were cleaned and washed. The crown, skin and eyes
of the pineapple were removed. Small slices (50 mm
X 50 mm X 50 mm) of the pineapple were blended
into the puree using the Waring® blender (National,
Malaysia) at the maximum speed for 30 seconds. The
puree was kept at 4ºC until further processing.
