The fenugreek gum powder is tasteless and odourless. It contains galactomannan which is a polysaccharide made of galactose combined with mannan, high molecular compound of mannose. Galactomannan has the property of viscosity which can convert milk into ice cream, cocoa into chocolate and when dissolved in water it forms gum.
The ratio of galactose to mannose for fenugreek is 1:1 when compared to guar gum and locust bean gum having ratio of 1:2 and 1:4 respectively, it can be found that fenugreek gum powder contains more galactose and so has superior solubility as well as dispersiveness which results to forming of stable colloid for a longer period of time. As Mannan is hydrophobic, it is completely insoluble in water. But, as fenugreek gum powder is the combination of galactose which is hydrophilic and mannan which is hydrophobic, fenugreek gum is surface active. It means
that fenugreek gum powder is an emulsifier which can mix water and oil. Thus, fenugreek gum works as a gum and an emulsifier both which has enabled its use as a stabilizer for food. Compared to other conventional gums like guar gum and locust bean gum, fenugreek gum has superior characteristics and so is used in many industries. |
