EVALUATION OF FOUR SORGHUM HYBRIDS THROUGH THE ...

Moisture Content:
The moisture contents of the starches and flours were determined using an
infrared moisture analyzer, IR-100 Power Module (Denver Instrument Company, Arvada
CO). Between 2 and 3 grams of starch or flour were placed on the machine and
measurements taken.
Crude Protein Content:
The crude protein of each flour was determined using a LECO FP-528 instrument
(Leco Corporation, St. Joseph, MI). The AACC approved method 46-30 (10 th edition)
was followed.
Ash Content:
The ash content was found using an adoption of the AACC approved method 08-
01. Modifications were as followed: 3 to 4 g of flour, 21 hours at 1000 o F, cool for 1 hour
in desiccator and weigh.
Statistical Design
Four treatments of sorghum flour were evaluated for grain and flour
characterizations. For grain characterization, two replications were performed. For flour
characterization, two replications were performed for particle size distributions, total
starch, starch damage, amylose content, and pasting properties. Triplicate readings were
taken for moisture, protein, and ash content.
All data were analyzed using SAS, Software Release 9.1 (SAS, Institute Inc.,
2003). When treatment effects were found significantly different, the least square means
with Tukey-Kramer groupings were used to differentiate treatment means. A level of
significance was observed at α = 0.05.
