This research investigated the effect modified solvent-shifting method on the formation, ordered structure, and morphology of V-type starch. Ionic liquid (IL) dissolution and hot ethanol aqueous incubation in gradient concentrations from 30 % to 80 % (v/v) were applied to optimize the relative crystallinity of V-type starch. The results showed that this new method worked in producing V-type conformation, and higher ethanol concentration tended to yield V-type starch with higher crystallinity and more disk-like shape structure within the ethanol range of 30-50 % (v/v).

Article Synopsis
  • - The study examined how treating different types of starch (rice, potato, and pea) with liquid nitrogen and ball-milling affects their structure and properties at multiple scales.
  • - Results showed that the starch granules changed from whole structures to irregular fragments, and prolonged treatment led to a breakdown of their crystalline structure, edging towards amorphization.
  • - As the starches became more amorphous, their thermal stability decreased, while their ability to absorb water and oil, swell, dissolve, and undergo hydrolysis increased, potentially expanding their usage in various applications.

The effects of soy protein isolate hydrolysate (SPIH) on the physicochemical properties and digestive characteristics of three starch types (wheat, potato, and pea) were investigated. Fourier-transform infrared spectroscopy and molecular dynamics simulations showed that hydrogen bonds were the driving force of the interaction between SPIH and starch. Furthermore, the SPIH was predicted to preferentially bind to the terminal region of starch using molecular dynamics simulations.

This study investigated the effects of pullulanase debranching on the structural properties and digestibility of maize starch (MS)-glyceryl monostearate (GMS) complexes. According to our results, the apparent amylose content of MS increased from 36.34 % to 95.
