Evaluation of Hardness of Waxy Rice Cake Based on the Amylopectin Chain-length Distribution
glutinous rice waxy rice chain-length distribution amylopectin hardness
2008/4/20
Waxy rice is used for staple and processed foods, and for its effective breeding an evaluation/selection index has been required. Here, the chain-length distribution of amylopectin from japonica waxy ...
Correlation between Property of Paste and Drying Rate on Degree of Swelling of Normal Rice Cracker
sembei drying swelling
2008/4/20
Sembei produced from normal rice is one of the traditional Japanese rice crackers (Beika) and is generally produced by roasting the dried rice paste. The degree of swelling after roasting the rice pas...
Cultivar Identification of Rice (Oryza sativa L.) by PCR Method and its Application to Processed Rice Products
rice DNA cultivar identification PCR processed rice product
2008/4/20
As the cultivars of rice affect markedly eating quality, processing suitability and price, identification or differentiation of rice cultivars is very important. The present authors developed suitable...
Plant α-Glucosidase: Molecular Analysis of Rice α-Glucosidase and Degradation Mechanism of Starch Granules in Germination Stage
α-glucosidase starch granules starch granule-binding sit
2008/4/20
In germination of plant seeds, storage starch is principally degraded by the combination of amylolytic enzymes. As starch is an insoluble granule, a conventional view of the degradation pathway is tha...
Process for Producing Brown Rice with Increased Accumulation of GABA Using High-pressure Treatment and Properties of GABA-increased Brown Rice
GABA brown rice high-pressure treatment
2008/4/20
Brown rice is commonly considered to have an effect on various diseases including life-style related diseases. Pre-germinated brown rice is characterized by its easier cooking properties and better ta...
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
