Rheological characteristics of binary composite gels of wheat flour and high amylose corn starch

The effect of addition of high amylose corn starch (Hylon VII or H) to wheat flour (WF) on the mechanical properties of the resulting binary composite gels (BCG) under small and large deformations was evaluated. To this end, the composite gels at different ratios of WF/H including 95:5, 90:10, and 85:15 were tested under a linear viscoelastic regime (LVE) in oscillatory angular frequency and a texture profile analysis in compression mode. However, the gel firmness was increased by Hylon VII addition, but the springiness was reduced. Since the adhesiveness and cohesiveness were not significantly different, no dilution effect was observed for the samples. Furthermore, the dominance of G' than G″ over the range of LVE and high fracture stress at high level of Hylon VII confirmed the high gel strength which can be attributed to the retrogradation of amylose and reduction of amylopectin from WF. The less frequency dependency of BCG revealed the solid-like response and strong gels structures with more elastic network. High value of α revealed a lower number of interactions within the gel network structures. Consequently, due to the high gel strength of BCG of WF/H, it can be exploited at high thermal operations such as retort process...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule.
