This study investigated the influences of paddy aging at 60 C and 70% relative humidity for 5 days on pasting properties of rice flours and molecular structures of major constituents in rice grain. The rice cultivars investigated included waxy rice Sanpah-Tawng 1 (SPT1), which contained 1.3% amylose and 8.3% protein. Non-waxy rice paddies; namely Pathum Thani 1 (PTT1), which had 14.1% amylose and 6.7% protein, as well as and Leuang Pratew 123 (LPT123), which contained 28.6% amylose and 9.6% protein, were also investigated. Paddy aging significantly changed the RVA pasting characteristics of rice flour pastes from all cultivars investigated (p&lt;0.05). All aged rice flour pastes had higher final viscosity than that of new rice flour paste. Fourier...

Cross-linked carboxymethyl rice starches (CL-CMRSs) were prepared from reactions between native rice starch and varied concentrations (0.1 to 15%w/w) of epichlorohydrin (ECH) in a simultaneous carboxymethylation-crosslinking reaction setup using methanol as solvents. The degree of carboxymethyl substitution was between 0.24 to 0.28, while amylose content decreased drastically from native starch. SEM images showed minor change on the granule surface, while XRD profiles indicated slight loss of crystallinity. In contrast, the water uptake (WU) and free swelling capacity (FSC) of CL-CMRSs increased significantly, compared to native starch, as a result of the modification. CMRSs cross-linked with 2% (M-2) and 3% (M-3) ECH yielded FSC values of 8.6 and 9.6 g/g,...

Broken rice was used for the production of dry-milled flour (pin milling). The physicochemical properties and the suitability of the flour for making rice noodle were investigated. The protein content decreased whereas the ash content increased with decreasing particle size. The amylose content of each fraction was similar. The swelling power and solubility index of the flour increased with the decrease of particle sizes. Rapid viscosity analysis indicated that the gelatinization temperature of the flour with smaller particle size was lower than that with larger size. The larger particle size flour exhibited lower peak, breakdown, and final viscosity. The texture of the rice noodle made from flour fraction of 75 μm particle size gave the highest tensile...

Several Thai traditional starch-based foods use alkali treatment to improve their quality and characteristics. However, limited information is available on how alkali changes the product quality. Therefore, the objective of this research was to investigate the effect of alkali treatment on appearance and texture of cooked glutinous rice. Glutinous rice kernels were soaked in 1N sodium carbonate (Na2CO3) or potassium hydroxide (KOH) for 24 h at room temperature. Sample soaked in water was used as a control. Cooked alkali treated glutinous rice had more yellow color and lower gelatinization temperature than the control. Moreover, they also had lower hardness and stickiness than the control (P&lt; 0.05). KOH had more pronounce effect than Na2CO3. The...

This study investigated the effect of freezing on quality of cooked rice. Four rice cultivars: Khao Dawk Mali 105 (KDML 105), Pathum Thani 1 (PT 1), Khao Tah Haeng (KTH) and Leung 11 (L11) were used in this study. After cooking and freezing, the frozen cooked rice was freeze-thawed up to 3 cycles. For the textural properties and sensory evaluation, the results showed that the unfrozen and freeze-thawed cooked rice from KDML 105 had the lowest hardness and the highest stickiness whereas rice from L11 had the highest hardness and the lowest stickiness. In addition, the freeze-thaw cooked rice had a tendency to increase hardness and decrease stickiness with subsequent freeze-thaw cycles. From a scanning electron micrograph, the surface of the unfrozen cooked...

Broken rice was used for the production of dry-milled flour by grinding on Pin Mill. Particle sizes distribution of the resulting flour shown that major portion was coarse flour. Physicochemical properties of the flour with differing particle sizes were investigated and utilized as raw material in rice noodle production; Sen Yai and Sen Mee. The protein content decreased whereas the ash content increased with decreasing particle size. The amylose content of each fraction was similar. Water absorption index (WAI) and water solubility index (WSI) were greater for fine flour. Fine flour also possessed high value of lightness (L*) and low yellowness (b*). Rapid visco analysis indicated that fine flour had lower gelatinization temperature while higher peak...
