Physicochemical 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 ...
متن کاملStructures of Four Waxy Rice Starches in Relation to Thermal, Pasting, and Textural Properties
Cereal Chem. 79(2):252–256 Waxy rice starches from three japonica cultivars (Taichung Waxy 1 [TCW1], Taichung Waxy 70 [TCW70], Tachimemochi) and one indica cultivar (Tainung Sen Waxy 2 [TNSW2]) were characterized for chemical and physicochemical properties. The amylopectin structures were different for the four waxy rice starches in terms of degree of polymerization (DP), average chain length (...
متن کاملPhysicochemical Properties of Low and High Amylose Cross-Linked Rice Starches
Background and Objectives: As chemical methods are commonly used to modify the starch properties, in this study, the influence of chemical modification using POCl3 on the rice starch function was evaluated. Materials and Methods: Rice starch was isolated by alkaline extraction of the proteins and cross-linked rice starches were prepared from reactions between native rice starch (low and high a...
متن کاملNucleotide sequence of rice waxy gene.
Rice waxy gene codes for the starch granule-bound starch synthase (EC 2.4.1.11) (1). To characterize its molecular structure, a rice {Oryza sativa subsp. japonica Hengfeng cultivar) genomic library was constructed in XEMBL-3 vector. Two overlapping genomic clones containing waxy gene sequence were screened and identified from this library by using maize waxy gene DNA as probe (kindly provided b...
متن کاملWaxy and non-waxy barley cultivars exhibit differences in the targeting and catalytic activity of GBSS1a
Amylose synthesis is strictly associated with activity of granule-bound starch synthase (GBSS) enzymes. Among several crops there are cultivars containing starch types with either little or no amylose known as near-waxy or waxy. This (near) amylose-free phenotype is associated with a single locus (waxy) which has been mapped to GBSS-type genes in different crops. Most waxy varieties are a resul...
