1.0 INTRODUCTION
Onion (Allium cepa) is a popular vegetable with most of the world
population. It is valued for it’s distinctive pungent or mild flavour and
constitute an essential ingredient for cuisines if many regions (Proctor
et al. 1999).
Onions are valued as food largely because of their flavor and texture
in them (Bankole et al. 2001). Their strong and appetizing taste
makes a particular welcome in addition to cereals diets even though
from a purely nutritional point of view onion rank relatively low
among other foods because of the large proportion of water which
they contain.
Commercially prepared onion products include dehydrated flaked and
onion powder. Dried onion products are mostly used in the food
processing industry common onion are normally available in three (3)
colors yellow red and white. Yellow onions (Allium fistulosum) also
called brown onions are full – flavored and are available for cooking
almost every type of food. Onions are also available in fresh frozen
canned caramelized pickled powdered chopped and dehydrated
forms. Frozen onion products include rings and small whole bulbs.
In some parts of west – Africa fermented preparations are made from
crushed or ground green onion leaves. These products are used to
flavor food at times when fresh onion are not available onion scale
may be sun dried for the same purpose (Brewster et al. 1994). Onion
ranks second only to tomatoes among vegetable on a world scale
(Mccollum et al. 1985).
In Nigeria the major onion producing area are the Northern part which
account for over 70% (Hui 1991) of the onion produced in a year.
Since it doesn’t thrive well in other parts of the country there is need
to make it available in these places. The fact that market cannot
absorb supplies of large quantities of onions and the stability of
demand through out the year has led to the development of processes
in which onion can be preserved. It is therefore important to processes
onion bulbs into a more convenient form that will make it available all
through the year.
Against the above back drop the study was carried out with the
following aim and objectives.
1.2 Aim
