CHAPTER ONE
INTRODUCTION
1.0 Pterocarpus mildbreadii are trees with edible
parts successfully budded, pterocarpus species (P.Soyauxii and P. mildbeadii
are reported to have different patterns of leaf flush, one spontanous and the
other intermitted making the first suitable for commercial production and the
second the home production (Okafor 1978). Pterocarpus mildbreadii being the
major case study both the vegetable and the seeds.
The vegetable is majorly used in our various home
for cooking. Pterocarpus mildbreadii (Oha seed) are not consumed by the people
from the eastern part of Nigeria. So it cannot be majorly stated the content of
this oha seed.
The demand for vegetable oils as a result of
diminishing source of oils and fats creates the needs for new sources as well
as exploiting sources that are currently unexploited in order to supplement the
existing ones (Minzangi et al. 2011).
As industrialists continues to rely mostly on the
popular vegetable oil like coconut oil, soyabeans oil, ground nut oil, palm oil
etc. for the preparation and production of their various products.

Plant lipids also posses nutritive value and have an
impact on human nutrition and the world economy.more than three quarters of the
edible and industrial oils marketed annually are derived from seed and fruit
triglycerol (Schimid & Ohlrogge, 2002). Seeds have nutritive and calorific
value which makes them necessary in diets. They are good sources of edible oils
and fats. The amount of energy provide by 1g of fat and oil when fully digested
is more than twice as many joules of protein and carbohydrate do. Fats makes
meals more satisfying, enrich its flavor and delay the unset of hunger
(Odoemelan, 2005). Unfortunately, insufficient availability of animal protein and
the costliness of available plant protein sources have also increased the need
for research on revealing lesser known under-utilized legumes and oil seeds of
nutritive value (Schimid & Ohlrogge, 2002).
