Pre-harvest sprouting (PHS) severely reduces rice grain yield, significantly affects grain quality, and leads to substantial economic loss. In this study, we aimed to characterize the physicochemical properties and processing quality of the Garumi 2 flour rice variety under PHS conditions and compare them with those of the Seolgaeng, Hangaru, Shingil, and Ilpum rice varieties and the Keumkang wheat variety. Analysis of the molecular structure of starch revealed uniform starch granules, increased proportions of short-chain amylopectin in DP 6–12 (51.0–55.3%), and enhanced crystallinity (30.7–35.7%) in rice varieties for flour compared with the Ilpum cooking rice variety. PHS significantly altered the starch structure and gelatinization properties of Garumi 2. It also caused surface pitting and roughness in Garumi 2 starch granules and decreased their crystallinity. Collectively, the findings of this study provide important novel insights into the effects of PHS on the physicochemical properties of Garumi 2 floury rice for flour.

Digestion Efficiency

Lotus seed starch (LS), dispersed (3%, w/v) in deionized water was homogenized (0–180 MPa) with high-pressure homogenization (HPH) for 15 min. The effects of HPH treatment on the physicochemical properties of the starch system were investigated. The properties were affected by HPH to various extents, depending on the pressure. These influences can be explained by the destruction of the crystalline and amorphous regions of pressurized LS. The short-range order of LS was reduced by HPH and starch structure C-type was transformed into B-type, exhibiting lower transition temperatures and enthalpy. The LS absorbed a great deal of water under HPH and rapidly swelled, resulting in increased swelling power, solubility and size distribution. It then showed “broken porcelain-like” morphology with reduced pasting properties. Digestion of pressurized LS complex investigated by a dynamic in vitro rat stomach–duodenum model showed higher digestion efficiency and the residues exhibited gradual damage in morphology.

The industrial importance of metal catalysts supported on reducible oxides has stimulated considerable interest during the last few years. This presentation reports on the study of the physicochemical properties of metallic rhodium supported on vanadium pentoxide (Rh/V2O5). Electron optical methods, in conjunction with other techniques, were used to characterise the catalyst before its use in the hydrogenolysis of butane; a reaction for which Rh metal is known to be among the most active catalysts.V2O5 powder was prepared by thermal decomposition of high purity ammonium metavanadate in air at 400 °C for 2 hours. Previous studies of the microstructure of this compound, by HREM, SEM and gas adsorption, showed it to be non— porous with a very low surface area of 6m2/g3. The metal loading of the catalyst used was lwt%Rh on V2Q5. It was prepared by wet impregnating the support with an aqueous solution of RhCI3.3H2O.
