HylonVII 70% Electro spinning
  • Aqueous glutaraldehyde 50% (GTA)

Fibers
Diameter
(200–700 nm)
Stable in water, non-toxic, 10 times more strength than uncross linked fibers. [41]
Hylon VII 70% Electro spinning
  • Acetic anhydride

Fibers
Diameter
(50 ± 5µm)
Uniform fibers obtained with small diameter at formic acid concentration (90%). [40]
Gelose 80 ~80 Electrospinning Fibers diameter between (2.15–4.02 µm) Better alignment occurred at higher rotational speed and lower ethanol concentration. Speed. [42]
Gelose 80 76 Electrospinning
  • Pullulan,

  • Sodium palmitate

Fibers,
Diameter (146 ± 50 nm)
Pullulan hindered starch association.
Tensile strength of the nanofiber composite
was found to be weaker than that of micro-sized pure starch fiber mats.
[43]

  • Dissolved in different formic acid dispersions (FA)

Fibers,
diameter (304 nm) at 100% formic acid and 84 nm at 80% FA.
Diameter decreased as water content increased [39]
Hylon VII 70 Special pressure vessel at 140–165 °C Hydrogel Lost its rigidity, due to the degradation of AP [45]
Hylon VII 61 Mixing gelatinized starch then autoclave treatment Alginate matrix Macro gels A high AM amount in the starch the produce gels with less degradation after digestibility compared with common starches and high AP starches. [46]
Hylon VII −70 MTGase Gel MTGase treated gels can withstand high temperature.
Hylon VII added to the gels supplied tighter, stronger, and denser protein network.
[47]
Hylon VII −71 Heated in high pressure reactor apparatus Guar gum/Xanthan gum Gel Guar and xanthan gums affected the pasting properties of normal maize starch more than those of waxy maize starch.
no new covalent bonds were formed between the guar and xanthan gums and the starches (normal, waxy and high-AM).
