Structures and physicochemical properties of six wild rice starches.
Starches from six wild rice cultivars were studied for their chemical structures and physicochemical properties and compared with a long-grain rice starch. The six wild rice starches were similar in morphological appearance, X-ray diffraction patterns, swelling power, and water solubility index but different in amylose content, beta-amylolysis limit, branch chain length distribution, thermal pr...
متن کاملPhysicochemical properties and digestibility of hydrothermally treated waxy rice starch.
Waxy rice starch was subjected to annealing (ANN) and heat-moisture treatment (HMT). These starches were also treated by a combination of ANN and HMT. The impact of single and dual modifications (ANN-HMT and HMT-ANN) on the molecular weight (M(w)), crystalline structure, thermal properties, and the digestibility were investigated. The relative crystallinity and short-range order on the granule ...

Cereal Chem. 84(5):527-531 Rice starches of long grain and waxy cultivars were annealed (ANN) in viscosity peak heights, lower setbacks, and greater swelling consistency. excess water at 50°C for 4 hr. They were also modified under heat-moisThe modified starch showed increased gelatinization temperatures and tore treatment (HMT) conditions at 110°C with various moisture contents narrower gelati...
متن کاملComparison of physicochemical properties and starch structure of red rice and cultivated rice.
Sixteen red rice accessions from the southern United States were studied for their physical, milling, pasting, and thermal properties, chemical composition, and starch fine structure relative to cultivated medium- and long-grain rice varieties. All red rice samples were medium-grain, but their physicochemical properties were different from those of Bengal, a cultivated medium-grain rice. Their ...
متن کاملAnalysis of the Physicochemical Properties and Grain Yield of Some Rice Promising Lines From Multiple Crosses
Grain quality currently represents a major problem in high yielding rice production in Iran and many other rice producing areas of the world. Quality assessment of rice involves the function of sensory tests and physicochemical determinations based on the chemical composition, cooking quality, gelatinization temperature and physical properties of cooked rice. These research genetic materials we...
