Fenugreek

Abstract

Trigonella foenum-graecum L. (fenugreek) is cultivated in various countries and consumed for many goals including medicinal applications (anti-diabetic, lowering cholesterol level, antioxidant, anti-microbial, anti-ulcer, lactation aid, and anti-obesity), making food (like stew with rice), roasted grains coffee-substitute, and controlling insects in grain storages. Generally, the seeds and leaves of the crop are commonly applied in food and pharmaceutical industries and contain several active ingredients that is linked to the properties of this plant. The chemical composition of fenugreek crop includes moisture, ash, protein, mucilage, lipids, alkaloids (mainly trigonelline), amino acids (particularly 4-hydroxyisoleucine), saponins (mainly diosgenin), flavonoids (mainly quercetin, rutin, and vitexin), fibers (mainly soluble dietary fiber), polyphenols, coumarin, vitamins (mainly vitamin C), and minerals (mainly calcium, zinc, sulfur, and phosphorus). Fenugreek as a hydrocolloid (known as galactomannan) can be applied as a thickening, emulsifying, stabilizing, gelling, and encapsulating agents and also it has positive effects on the textural and appeal properties of food and pharmaceutical products. In this chapter, a review of the methods for extraction and identification of different substances present in fenugreek is evaluated.
