Preparation,properties and applications of natural biomass materials(Ⅸ)The soluble,stable,multi-functional natural polysaccharide gum:fenugreek gum
Fenugreek gum(FG)is one kind of water-soluble natural polysaccharides extracted from the endosperm of fenugreek legumes.It has appropriate physical and chemical properties,such as water solubility,water binding capacity,thickening ability,thermal stability,emulsifying ability,film-forming property,as well as salutary pharmacological actions like hypoglycemic activity,antihyperlipidemic effect,and antioxgenation property.Moreover,its physical,chemical properties and application performance can be significantly improved by physical modification,chemical modification,blending modification and enzymatic modification.Therefore,fenugreek gum has been gained more and more attention in many fields,including daily-use chemical industry,food processing industry,pharmaceutical industry,and oil recovery.In this paper,the name,extraction source,chemical structure,the main physicochemical properties of fenugreek gum along with its extraction and purification technologies,common modification methods are briefly presented.Furthermore,the application areas of fenugreek gum and its modified products,and the current challenges faced in its development,as well as the future research direction and prospects for the development of fenugreek gum are also discussed in this paper.
