The molecular structural parameters of six normal rice starches with different amylose contents were investigated through their iodine absorption spectra and gel permeation chromatography of fully branched and debranched starches. The thermal and digestion properties of starches were also determined and their relationships with molecular structural parameters were analyzed. Results showed that ...

The objective of this study was to understand the resistant-starch (RS) formation during kernel development of a high-amylose maize, GEMS-0067 line. The RS content of the starch, determined using AOAC method 991.43 for total dietary fiber, increased with kernel maturation and increase in the amylose/intermediate component (IC) content of the starch. Gelatinization of the native starches showed ...

The starch from eight ethyl methanesulfonate (EMS) treated M4 families of the corn (Zea mays L.) inbred line B73 was analyzed using differential scanning calorimetry (DSC), a Rapid Visco Analyser (RVA), a texture analyzer (TA), and scanning electron microscopy (SEM) coupled with image analysis. The eight families were chosen from 144 families previously selected for having starch with unusual D...

Grain quality currently represents a major problem in high yielding rice production in Iran and many other rice producing areas of the world. Quality assessment of rice involves the function of sensory tests and physicochemical determinations based on the chemical composition, cooking quality, gelatinization temperature and physical properties of cooked rice. These research genetic materials we...

A series of hydroxypropylated starch (HPS) that can be dissolved in water at 60–65 °C was obtained via two-step method system from corn starch. The structure and property the HPS its gelatinization temperature were characterized by Fourier transform infrared spectrometer, nuclear magnetic resonance spectroscopy (1H NMR), X-ray diffraction (XRD), differential scanning calorimetry (DSC), electron...

HIGHLIGHTS Extracts and characterizes the starch from stem of pineapple plant. Pineapple shows small granule size high gelatinization temperature. It possesses A-type crystals is more viscous compared to corn starch. Results indicate usefulness this agro-waste in food industries.

Abstract: The objective of this work was to select cassava (Manihot esculenta) genotypes from the Brazilian germplasm bank with a functionality similar that waxy starch. A total 881 were pre-selected using principal component analysis and hierarchical clustering, their industrial potential compared 7745-5WX WX-Maize maize clones, both used as references. Two stood out: BGM0036 BGM0083. Samples ...
