Fenugreek (Trigonella foenum-graecum L.) is known as methi in Hindi and vendayam in Tamil. The largest producer of fenugreek in the world is India. Fenugreek seeds are often roasted to reduce their bitterness and enhance their flavour. Galactomannan in fenugreek has been identified to lower blood glucose, hence separation of galactomannan are undertaken at industrial levels (eg. M/s. E.I.D. Parry (India) Limited, Bio Products Division, Cuddalore, Tamilnadu, India) to produce anti-diabetic nutraceutical. Galactomannan are the major polysaccharide found in fenugreek seed and represent approximately 50% of the seed weight. The remaining 50% of the material from fenugreek in galactomannan extraction industry is available as galactomannan depleted fenugreek residue (GDFR). The fenugreek seed and GDFR contained crude protein 26.65 and 33.79%; metabolisable energy 3125 and 3315 kcal/kg; lysine 1.13 and 1.27%; methionine 0.61 and 0.73% respectively.
