“Estimation ofNutritional and Starch characteristics of fresh African bitter yarn commonly cultivated in the south eastern part of Nigeria:- Nnadi, Lucky O.
ABSTRACT
This study is aimed at evaluating the starch
characteristic and nutritional composition of fresh three leaf yam popular
known as bitter yam. The qualitative and quantitative phytochemical, proximate
and mineral analyses of bitter yam were carried out on fresh samples. The
results revealed the presence of bioactive constituents with carotenoid being
the highest present with a percentage of 98.26mg/g. Other bioactive compounds
include alkaloids (2.72%), Saponins (4.81%), Flavonoids (0.87%), Tannins (0.52%),
phenol (1.50%), glycoside (0.07%) and cyanide (0.41mg/100g). Proximate analyses
revealed the presence ofthe following substances in varying composition: crude
fibre had the highest composition with a percentage of 37.50%, followed by
carbohydrate with a percentage of 23.15% .others include protein (8.75%),
moisture (19.00%), fats and oil (8.60%), and ash (3.0%).The results obtained
from the quantitative analysis of the mineral content showed the presence of
the following mineral; Fe (0.06mg/g), Mg (0.32mg/g), Na (0.28mg/g), Ca
(0.02mg/g), P (0.08mg/g) while potassium (K) and manganese (Mn) were not
detected. Finally, the starch characteristic of the sample were as follows:
amylose content 25.80% and gelatinization temperature 85°C at 31 minutes time
interval. The evaluation of the nutritional and starch characteristics have
unveiled that this plant is culturally, socioeconomically and medically
important. This present study recommends this plant food as diet and natural
therapy for patients suffering from diabetes, hypercholesterolemia and
atherosclerosis.
