The Functional Properties and Digestibility of Round and Wrinkled Pea Flour in Swine
… but their starches differ in the proportion of amylose and amylopectin. Wrinkled peas have a higher proportion of amylose due to the deficiency of the starch branching enzyme I (SBEI). In contrast, round peas have a lower proportion of amylose and higher total starch content. A higher proportion …

Evaluation of the Impact of Near-Infrared Spectroscopy on Genomic Prediction Accuracy for Hybrid Rice Traits
… characteristics such as glycemic index, amylose content, and protein levels in rice varieties, little research has explored its application in hybrid rice. This study addresses that gap by applying NIRS to predict phenotypic traits in 1,488 seed samples from 191 hybrid rice lines across …

Preparation of emulsifiers from pea and corn starches using octenyl succinic anhydride modification
… of starch, db). Native PS consisted of more amylose (41.5%) than NCS (32.9%) and WCS (1.7%). The degrees of substitution (DS), thermal properties, and pasting properties of the derived OS starches were determined. Incorporation of OS groups significantly alter the thermal and pasting …

Processing and genetic effects on resistant starch in corn flakes
… of processing and genetics on resistant starch content in corn flakes. Cooking (15 psig/121°C, 50 min), drying (100°C, 30 min), tempering (room temperature, 30 min) and toasting (200°C, 60 s) resulted in flakes produced in laboratory that had similar color parameters (L, a and b values) but …

Preparation, characterization, and evaluation of sorghum flour with increased resistant starch content
… effective process to increase resistant starch content of sorghum flour and investigate the effects of sorghum protein matrix on starch digestibility. Samples of white sorghum flour (28.9% amylose content) with different moisture contents (0%, 12.5%, 20%, and 30%) were treated at different …

Analysis of Starch Branching Enzyme 1 (SBE1) Gene in Maize
… the short arm of chromosome 5 (5S) for endosperm amylose content. In that original study, both low and high amylose parental lines, H99ae and GEMS-0067 respectively, were homozygous recessive for <em>amylose extender 1 (ae1)</em> and the polymorphism responsible for this QTL was additive …
