Abstract:
... Waxy, low-amylose and high-amylose rice starches were chosen to separate inner blocklets and outer shell from their granules under incomplete gelatinization. Isolated outer shells and swollen or merged inner blocklets, based on morphological structure of broken granules, were used as a probe to study the mechanism of differences between outer and inner blocklets formation, through molecular charac ...

Abstract:
... Flow characteristics and the mechanical theory of granular flows in dense sheared granular systems have yet to be fundamentally understood because of the complexities and discreteness of these systems. This study derives the appropriate equations and effects of mechanical parameters on fluctuation velocity, and investigates the solid volume fraction for a dense granular assembly sheared between tw ...

Abstract:
... Native maize starch (NS) is modified by annealing (ANN) and cross‐linking (CL) processes, and also by using two different combinations of the ANN and CL processes (ANN‐CL and CL‐ANN). The effects of modifications on physicochemical properties and in vitro digestibility of starch are studied. The results show that CL‐ANN significantly (p < 0.05) improves swelling power and decreases solubility. The ...

In contrast, a triple mutant impaired in starch degradation by its additional lac ...

... Protein misfolding is a topic that is of primary interest both in biology and medicine because of its impact on fundamental processes and disease. In this review, we revisit the concept of protein misfolding and discuss how the field has evolved from the study of globular folded proteins to focusing mainly on intrinsically unstructured and often disordered regions. We argue that this shift of para ...

To test this ...
