Background: Oat is one of cereal grain which has about 10-15 species of true grasses (familyrnPoaceae). Even though, Avena sativa L (common oat) is the most important one amongrncultivated oat in most parts of the globe; four other species are grown as crops of minor orrnregional importance of which Triticum decocum which is cultivated in Ethiopia is one. Triticumrndecocum is a half-weed, half-crop with erect stems which are small and fairly stiff withrnequilateral panicles and medium size, just very drooping.rnObjective: The main purpose of current work is to study the physicochemical properties ofrnTriticum decocum starch, and evaluate its binding and disintegrating properties in paracetamolrntablets.rnStatement of the problem: With the recent global renewed interest of natural polymers forrnindustrial consumptions, the demand for the starch is expected to hit 230 million metric tons perrnyear by 2015 globally. Current starch demand of Ethiopia which is more than 400 tons per yearrnis imported from other countries. The need is escalating with industrial advancement. To cope uprnwith these demands, potential endogenous sources of starches including, Triticum decocumrnstarch, should be considered if being economical and sustainable supply is anticipated.rnMethods: Different methods previously described elsewhere were used to achieve the abovernobjective with slight modification as its importance.rnResult and Discussion: The proximate composition of the starch on dry weight basis was foundrnto be 0.23 % ash, 0.26 % protein, 1.54 % fat and 56.31 % starch. The total amylose content wasrn28.4 % with 20.11% apparent amylose and 29.19% lipid complexed amylose. SEM showed ovalrnand spherical shaped granules. The particle size distributions of the starch showed monomodalrnnormal particle size distribution with the average volumetric particle diameters being aboutrn23.03Î¼m, and specific surface area 0.7186 m2/g. XRD showed a pattern that is typical of A-typernwith a distinctive maximum peak at around 17Â° 2Î¸. At all relative humidities, its water sorptionrnproperties resemble that of Zea mays starch. It has unique swelling power and solubility in waterrnat different temperature. Viscosity curves of 10% starch paste showed a peak viscosity ofrn1926cP. Its cold paste viscosity and hot paste viscosity were 4236cP and 1720 cP, respectively.rnThe breakdown and set back of Triticum decocum starch were 206 and 2647cP, respectively.rnIIrnPowder mix of the starch with paracetamol has poor flow and compressibility properties. Butrnafter wet granulation, the granules have good flow and compressibility properties. Tabletrncrushing strengths, friabilities, disintegration times and dissolution profiles results had shownrnpromising results.rnConclusion and RecommendationrnBased on the above results, Triticum decocum starch can be used both as a binding agent andrndisintegrant. It has a better binding ability than Zea mays starch, giving tablets of higher strengthrnand less friability. However, tablets containing Triticum decocum starch disintegrate slightlyrnmore slowly. Different methods of extraction, modifications, and other use evaluations had betterrnconducted on the starch.rnKey Words: Triticum decocum, physico-chemical properties, chemical composition, flow andrncompressibility.
