Title: Gums And Stabilizers by, Yishen Tey

I hope i can do a summary for me and for you. It is according to the handout from the portals. Freemind is still in the process, on the way figuring out)

Hydrocolloid- polysaccharide with substituent which detemine the properties of hydrocolloid

Function of hydrocolloid : -thickening agent -gelling/texturizing agent -stabilization of emulsion -particles suspension -control of crystalisation -encapsulation: capsule flavor -film formation

There are only non-ionic or ionic food gums.(how about non-food gums?) Cationic food gums are toxic.

DS determine the speed of hydration. >DS, hydrate faster.

DP determine the speed of hydration&viscosity >DP, viscosity higher, hydrate slower.

Gum properties affected by -MW -monosaccharide composition (where polysaccharide made from) -substituent(number, type, how they distribute)
