Native Rice Starch and Linseed Gum Blends: Effect on Pasting, Thermal and Rheological Properties
rice starch linseed gum pasting properties thermal properties blends
2015/12/30
Native rice starch was replaced at 3, 6, 9, and 12% with linseed gum. The objective of replacement was to modify the
starch properties as an alternative to chemical and enzymatic modification. In th...
Effect of extrusion treatment on the thermal stability and structure of corn starch with different emulsifiers
crystallinity modified starches extrudate complexes
2015/10/9
Corn starch was treated with raw moisture (30%), screw speed (160 rpm), extrusion temperature (30, 55, 80, 105, 130, and 155°C), and emulsifier (1.2%) to produce the starch extrudate particles in a tw...
