the bitterness in citrus fruit juice is mainly due to the presence of naringenin which makes the
product unacceptable by some consumers. Removal of this bitterness, to certain extent, has
been achieved by addition of partially purified naringinase to the citrus fruit juice. Naringinase
produced by
P. purpurogenum
is partially purified, and lyophilized before use. Maximum removal
of naringenin content (74%) was achieved at naringinase concentration of 1.0g/L, with incubation
at 40°C
