文摘
- •
Degalactosylated xyloglucan gels develop a lamellar morphology if incubated at 37 °C.
- •
Irradiation reduces the molecular weight of the polymer in a dose-dependent fashion.
- •
The auto-organization in lamellae is faster for low dose irradiated xyloglucans.
- •
Irradiation at too high doses impairs ordering leading to weaker gels.
- •
Absence of cytotoxicity from gels leachates is demonstrated.
