Evaluation Of The Physico-Chemical Properties Of Ethiopian Maize Variety (Bh-660) For Dextrose Production
Dextrose was produced from locally available hybrid variety of maize
(Bako Hybrid- 660) in Ethiopia, using acid extraction. The variety was
selected as an experimental input from Bako Agricultural Research
Centre for the production of intermediate product starch using wet
milling and end-product dextrose. The proximate composition values in
the wet, milled, dried and cleaned white dent 2000 g BH-660 maize when
steeped in 0.3% sulfur dioxide for 46 hrs at 50°C were determined.
The mean values were 11.74%, 64.15%, 4.51%, 10.23%, 6.53% and 2.81%,
for moisture content, total starch, germ, gluten, husk and fibre,
respectively on dry weight basis. The total starch obtained from wet
milling was 91.8% pure starch by mass. The proximate analysis values of
moisture, crude protein, crude fat, crude fibre and total ash content
of the sample were 7.65 %, 4.89%, 0.35%, 0.75 % 0.29 % , respectively
on dry weight basis. Besides these, pH value was also determined to be
4.79. This obtained starch was hydrolyzed by an acid extraction method
for the production of BH-660 maize dextrose. An average yield of 91.64%
dextrose result was obtained and from this, 92.24% was pure dextrose by
mass. Analysis result revealed that moisture, crude protein, crude fat,
crude fibre and total ash content of the produced dextrose were 6.24%,
0.11%, 0.25%, 0.30% and 0.03%, respectively on dry weight basis. In
addition, the pH value of 6.28 was determined. The control dextrose
obtained from Ethiopian Pharmaceutical Manufacturing Share Company
analysis values of moisture, crude fibre, crude fat and dextrose
content were 5%, 0.24%, 0.23% and 93.73%, respectively on dry weight
basis. From these data, it can be concluded that the BH- 660 maize
variety has a significant potential for the production of high quality
starch and dextrose, which can be used as a raw material for starch and
dextrose processing industries
