Biochemical Composition and Nutritional Evaluation of Barley Rihane (hordeum Vulgare L.)

BACKGROUND Many experimental studies have suggested an important role for barley Rihane(BR)in the prevention of colon cancer and cardiovascular diseases. The objective of this study was to evaluate the physico-chemical properties and nutritional characterizations of BR compared to other varieties grown in Tunisia (Manel, Roho and Tej). MATERIAL AND METHODS Total, insoluble and soluble dietary fiber(β-glucan), total protein, ash and some minerals of BR and Tunisian barley varieties were determined. RESULTS The results revealed that BR is good source of dietary fiber mainly β-glucan compared to the other varieties. This variety is a relatively rich source of phosphorous and potassium and it contains many important unsaturated fatty acids. BR has higher nutritional value than other varieties. CONCLUSION Barley Rihane has significant nutritional characterizations compared to others Tunisian barleys varieties.
