A Note on the Metabolic System for the Synthesis of the Tandem-Cluster Structure of Amylopectin in Rice Endosperm
amylopectin cluster rice starch branching enzyme starch debranching enzyme starch synthase
2008/4/20
The tandem-cluster structure of amylopectin must be a refined product that higher plants have evolved from the cluster-free random branched structure of glycogen. During the evolutionary process, plan...
Effect of Heat-moisture Treatment of Glutinous Rice on Promotion of Hardness of Mochi-kiji
glutinous rice heat-moisture treatment gelatinization temperature hardness of mochi-kiji
2008/4/20
Effect of the heat-moisture treatment of glutinous rice on the gelatinization temperature, the color tone of rice, and promotion of the hardness of mochi-kiji were studied. Heat-moisture treatment was...
Effects of Milling Ratio on Properties of Endosperm Starches and Rice Flours from Milled Japanese Rice Grains
milling milled rice grain pasting properties gelatinization properties starch structure
2008/4/20
Flour and endosperm starch prepared from rice grains of three Japanese rice cultivars milled from 90 to 30% of their original weight were subjected to physicochemical/structural analysis in order to e...
Effects of Soaking and High-Pressure Treatment on the Qualities of Cooked Rice
high pressure rice gelatinization, NMR imaging, digestibility
2008/4/20
In this study, changes in rice qualities from High-Pressure (HP) treatment were investigated. Milled rice grains were presoaked in water at 25 and 55°C for 30 min, subjected to HP treatment at 400 MPa...
Measurement of the Concentration of Bioactive Gibberellin in Germinating Rice Seed Using the α-Amylase Induction from Aleurone Cells
rice, aleurone cells α-amylase bioactive GA
2008/4/20
Measurement of the concentrations of bioactive gibberellin (GA) in germinating cereal seeds is important to grasp the molecular mechanisms of storage starch degradation following the activation of ale...
Molecular Structures and Some Properties of Rice Starches from Hokkaido Cultivars
rice amylose amylopectin pasting properties
2008/4/20
The molecular structures and some properties of starches of Hokkaido rice (Hoshinoyume, Kirara 397 and Aya) were examined and compared with Akita rice (Akitakomachi). The Hokkaido cultivars showed a C...
Multiple Evaluation of Cooked Rice Retrogradation in Early Stage of Storage
cooked rice early stage retrogradation instrumental methods sensory test
2008/4/20
Early stage (within 24 h storage) retrogradation of cooked rice stored at 4°C or 15°C were evaluated by instrumental methods, that is, differential scanning calorimetry (DSC), whiteness, hardness and ...
Structure and Properties of Endosperm Starches from Cultivated Rice of Asia and Other Countries
rice starch indica japonica javanica super-long chain
2008/4/20
Starch granules were prepared from mature grains of 75 cultivars (23 indica, 27 Chinese indica, 6 japonica and 19 javanica) of rice originating in Asia and the other countries, including Brazil (4), C...
α-Amylase Affects Starch Accumulation in Rice Grains
α-amylase Oryza sativa L. ripening seeds starch transgenic plant
2008/4/10
isoforms I-1 and II-4 were found in rice grains during ripening, α-amylase II-4 being the most predominant isoform. To determine their functions in ripening seeds, we generated a series of transgenic ...
Sorption and thermal properties of rice, potato starch, and oat flakes
moisture content humidity water activity enthalpy evaporation heat bound water
2014/3/3
A precise design of the equipment for thermal sterilisation of rice, potato starch, and oat flakes by dry heat requires the knowledge of the relevant values of physical properties of these products. W...
The properties of rice after microwave irradiation were evaluated by means of amylograph and enzymic determination of the total and the damaged starch. The content of the total starch was not affected...
Effect of Starch Properties on the Extent of Breakage of Non-Glutinous Dried Rice Cake
breakage of dried rice cake α-amylase degradation of starch
2010/11/23
This study was conducted to determine the reason why dried rice cakes for non-glutinous rice crackers (Senbei) often break in the production process. Breakage after drying at 40°C for 12 h was found t...
Near Infrared Spectra of the Outer Layer of Flour of Stored Milled Rice
