文摘
- •
Gelation of Gum tragacanth with small amounts of PVA without using other chemicals.
- •
Gelation was investigated at up to four freeze-thaw cycles and two thawing temperatures.
- •
Gel fraction, syneresis as well as mechanical properties and microstructural characteristics of the obtained gels were studied.
- •
Mechanical properties of the gel samples were reinforced by increasing freeze-thaw cycles and decreasing thawing temperature.
