Effect Of Different Extraction Methods On The Fer Physicochemical Properties Of Starch From Green (Improved) And Brown (Local) Mungbean (Vigna-Radiata(T.) Witczek) Cultivars
ABSTRACT
Starch from Mungbean (Vigna-radiata
(L.)Wilczek), Green (Improved) and Brown (Local) was extracted using different
extraction methods. The physicochemical properties, Starch yield, Starch
Isolation efficiency and Total Starches of the Mungbean starches were analyzed
using standard methods. The starch yield ranged from 14.90 to 28.50%, starch
isolation efficiency ranged from 132 to 256%, total starch ranged from 51.15 to
57.86%. The proximate composition of the Mungbean Starch had the following
ranges dry matter 91.50 to 92.70%, moisture content 7.30 to 8.50%, protein
content ranged from 0.27 to 0.50%, fat content from 0.09 to 0.17%, the ash
content from 0.12 to 0.20%, the carbohydrate content from 90.86 to 91.86%,
energy value from 366.16 to 370.83kcal respectively. The functional properties
of the mungbean starches had the following ranges bulk density 0.52 to 0.58g/cm
3 , oil absorption capacity 1.12 to 2.4lg/ml, water absorption capacity ranged
from 1.0 I to 2.02g/ml, emulsion capacity from 36.50 to 63.50sec, wettability
ranged from 1.55 to 3.36secs, gelation temperature from 71.56 to79.25C,
swelling power ranged from 18.35 to 19.08%, gelation time range from 4.10 to
4.26secs and solubility index from 15.29 to 16.61%. The paste clarity values
ranged from 17.12 to 17.42%, amylase from 29.23 to 34.20%, hydration capacity
from 0.67 to 0.70g/s, hydration index from 0.71 to 0.73%, and viscosity from
761.19 to l0l2.24pas). The results indicate that Alkali extraction method gave
the highest starch yield (28.50%) and Cold extraction method gave lowest starch
yield (14.90%). modified Mungbean Starch can be put into various technological,
industrial and food application uses.
