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.
